Ice Hunting Guide
« on: June 20, 2017, 01:33:18 am »
Introduction

The science team urgently needs ice sightings from the logs.
Consequently, we are making a first pass through selected logs to collect ice information only.
At a future point we will make a second pass through these logs to collect the weather data and events.

For ice hunting, only the tabs in the tracker with the green stripe need to be done, and only one transcription is required per page.


To make our ice and weather reports more useful, mapurves (Michael) has developed a system to plot the position of the ship on an hourly basis.
For this purpose, we are now asking transcribers to record Course and Distance and Sailing Information.


Please read this first to get an overview of how the new system works
(Note that this section primarily describes general transcribing rather than the ice hunting we are concentrating on now.)

https://sites.google.com/view/owfaq/introduction

The rest of that site has links to the tutorial materials listed below, and has links to the transcribing resources (spreadsheets, trackers, and data uploading forms) that you will be using to participate.
It's a work in progress, so make sure to check back from time to time for updates.

Getting Started

Here are some links to demos and tutorials to help you install, configure, and start using our system:

Installing LibreOffice


Although LibreOffice versions are available for MacOS and Linux, the current version of the spreadsheet only works on Microsoft Windows.

Tutorial Docs and Graphics


Screen Video Demos






What to Transcribe:





See the Additional Information section at the end of this document for information that doesn't fit neatly elsewhere and for updates.





Some people have asked about doing weather and/or events. I will release current instructions as soon as possible. Until then, here are some out of date but - hopefully - still helpful instructions.
Weather
Events

Transcribing: Introduction

Please note that ONLY data entered in a marked box will be saved.
The marked boxes are:
  • Magenta for Date
  • Red for Distance, Course, and Weather
  • Blue for Events and Locations

You will notice that the transcribing box becomes opaque when you begin to type.
This is a feature of the spreadsheet that we just have to live with.
If you find you have forgotten what you were typing half way through, press 'Enter' or 'Esc', check the information again, then double click the box to open it and complete your entry.
Double click any completed cell to open it for correction.

An XML file is generated when the 'Write Data' button is clicked on completion of transcribing a page.
Use a program like WordPad or NotePad to open the file if you want to review your saved data.
Please do not edit this file or re-save it.

In earlier phases of Old Weather, strict TWYS (Type What You See) was the rule.
With a few exceptions, errors were not to be corrected, events had to be transcribed exactly as they appeared, and no comments could be added.
Although TWYS is still the basic rule, you will see that some flexibility has been added.
Also, we now have a 'Transcriber Comment' event type that allows you to add your own comment to the log page.

Here are some general guidelines:
  • If you can read something, type it exactly as it is written.
    If you cannot read something, feel free to guess at it.
    If you are totally lost, you can replace the letter or word with one or more tildes.
  • Fractions, like 1/2, can be tricky.
    If the fraction is associated with a number (21/2), please convert it to a decimal (2.5).
    If the fraction is associated with a direction (N1/2E), please transcribe it as a fraction (N1/2E). Here the 1/2 indicates 1/2 point (1 point = 11.25 degrees).
    For example: N1/2E is 5.625 degrees, but N.5E is 0.5 degrees.
  • Degree (o), minute ('), and second ('') symbols should be omitted.
    If required for clarity, the word degree/degrees can be spelled out.
  • A drawing of an anchor can be transcribed as anchor or anchored.


Adjusting the alignment

Note: These images come from an older version of the spreadsheet so what you see will be slightly different.
Nonetheless, the comments below still apply.


Occasionally, you will see a page that is slanted.



In this case, use the 'Adjust Angle' arrows to rotate the image (clockwise or counterclockwise) so that the red grid lines are parallel to the printed grid lines.



Hint: Do this before adjusting the horizontal and vertical position of the grid on the page (below).

Sometimes the red grid is not correctly lined up with the log grid.



This can easily be fixed by dragging the spreadsheet column separator between columns B and C to move the red grid to the correct horizontal alignment and/or by dragging the spreadsheet column separator between rows 4 and 5 to move the red grid to the correct vertical alignment.
The cursor will change to a left-right arrow ↔ when your cursor is in the right place to do this.



You can also drag the spreadsheet column and row separators (A, B, C ... 1, 2, 3 etc at the top and left-hand side) to fine tune positions of individual red grid lines if you find that helpful.
However, the alignment does not need to be precise; just close enough to be able to make sure you are getting the log entries into the correct cells.


Viewing log pages in your browser

Looking at previous and subsequent pages is helpful when you are having trouble reading something; other instances of the word(s) may appear.

You can open a simple image of the log page(s) by clicking the 'Open In Browser' button.
This will open the JPG image in your default browser.
You can look at other pages by editing the URL.

Starting from:
https://catalog.archives.gov/OpaAPI/media/12095758/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-08/atka-agb-3-1952-08-0051.jpg
You can look at the corresponding events page:
https://catalog.archives.gov/OpaAPI/media/12095758/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-08/atka-agb-3-1952-08-0052.jpg
You can also look at the events page for the following day:
https://catalog.archives.gov/OpaAPI/media/12095758/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-08/atka-agb-3-1952-08-0054.jpg

Inserts

Inserts in a logbook generally require multiple page scans.
Except for the date, duplicate data do not need to be transcribed.

For side-attached inserts:
On the first page transcribe: all weather records, location(s), the date, and anything of interest on the insert (e.g., the person on the sick list).
On the second page transcribe: anything of interest on the back of the insert (in this case it is blank), the date, and anything of interest on the log page.

For top-attached inserts:
On the first page transcribe: all weather records, location(s), the date, and anything of interest on the insert.
On the second page skip the weather records and location, and transcribe: the date and anything of interest on the log page.
If the date is not visible, as is the case here, and you are able to determine the date, add a Transcriber Comment with Subtype Date with the date in the Event Text field using the format YYYY-MM-DD.

For all pages with inserts, please add a Transcriber Comment with Subtype Inserts. It is not necessary to enter any Event Text.

Transcribing: Date

Sometimes the date will be on the weather page, sometimes it will be on the events page, and sometimes it will be on both.
The date should always be transcribed, even when there is nothing of interest to you on the page or when, because of inserts, there are multiple pages with the same date.

In the logs we are currently using, the date can usually be found at the top of both pages.
You will see a magenta box above the log page. It does not cover the date, but that does not matter.

     

Click inside the magenta box and enter the date in YYYY-MM-DD format.
For example, May 6, 1914 would be entered as 1914-05-06.
Please be sure to use the minus character '-' rather than the slash character '/'.
You may depart from the TWYS rule and add or correct the date.
If you do so, it would be helpful if you added a Transcriber Comment with a Subtype of Date and a brief explanation.



Like me, you may have noticed that if the date box happens to be active when you click Clear Data, the date will not be deleted.
Hanibal has pointed out that you can make use of this fact.
If you double-click the date box before clicking the Clear Data button the date is not deleted.
This allows you to edit the day rather than retyping the whole date.



When the date has been entered, the Date X in A14 changes to solid green.

Transcribing: Locations

  • Transcribe the 8:00, Noon, and 20:00 positions (usually latitude and longitude), if given.
    If they are all the same, as when the ship is in port, noon is sufficient.
    If both observed and dead reckoning positions are given, it is not necessary to include the dead reckoning position.
  • If ice is reported, please transcribe the location information on the events page.
  • One big change from previous OW interfaces is that we are now encouraged to do more processing of the location information ourselves and to make corrections.
    Strict TWYS is still acceptable.
    However, you can now convert a place name or a place name with bearings into decimal latitude and longitude where possible. Also, if the cardinal direction is missing or incorrect and you are confident of the correct value, please enter the correct value (you can add a Transcriber Comment event to explain what you changed).
  • The type Not Specified is used with a latitude and longitude when you do not know whether it is Observed or DR (Dead Reckoning).
  • In some logs you will see Celestial, Electronic, and Visual as the method.
    All of these are transcribed as Observed.



You will find the Forum's Geographical Help board and OW Find Place (by our very own mapurves [Michael] & propriome [Matteo]) extraordinarily helpful for dealing with place names and bearings.

You may also find Show Point from Latitude and Longitude useful for locating your ship when only latitude and longitude are give.



In most of the logs we are currently using, the 8:00 (8 AM), Noon, and 20:00 (8 PM) positions can be found in the section below the weather data.
However, in some logs from the second half of 1955, the positions are at the top right and there are additional positions in the synoptic observations table at the bottom.
The positions may not all be filled in.




https://catalog.archives.gov/OpaAPI/media/12095688/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-06/atka-agb-3-1952-06-0007.jpg

Right click on or next to the position - but be sure that your cursor is within the blue box - and select Location Wizard from the popup menu.
You can click anywhere inside the blue box, but you will probably find it less confusing if you click near the information you are transcribing.

Enter the time or select it from the drop-down list.
In this example select 8 AM.

In this example we do not know if latitude and longitude entries are Observed or Dead Reckoning, so select Not Specified.

Enter the latitude and longitude in the Deg/Min/Sec Type-In box.
Note that 21/2 minutes is entered as 2.5 minutes.



The decimal versions of the latitude and longitude, the format requested by the science team, are generated automatically and shown in the Output Preview block.


Warning: Some log keepers mix minutes with decimals and minutes with seconds.




In cases where no latitudes and longitudes have been entered, check the top of the page for a location name or description.


https://catalog.archives.gov/OpaAPI/media/12095758/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-08/atka-agb-3-1952-08-0029.jpg

Do not click next to the place name.
Right click within the blue box below the weather records, and select Location Wizard from the popup menu.

In this case it is probably best to leave the time blank.

The Type will be Place.

Enter the place name or description in the Text Input box under Place/Bearing/Passage/Other (Raw/TWYS).

If you feel more ambitious, you can look up the latitude and longitude of the place, select Decimal under Input Mode, and enter the latitude and longitude in the Decimal Type-In box.
The science team has requested that we do this when possible.



A place name logged in one of the latitude/longitude boxes can be entered in the same way.



This case is similar to the case above but instead of a place name (AT), the origin and destination (PASSAGE FROM / TO) have been filled in.


https://catalog.archives.gov/OpaAPI/media/12095758/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-08/atka-agb-3-1952-08-0012.jpg

Do not click next to the place names.
Right click within the blue box below the weather records, and select Location Wizard from the popup menu.

In this case it is probably safest to leave the time blank.

The Type will be Other.

Enter the place names in the Text Input box under Place/Bearing/Passage/Other (Raw/TWYS).
In this case it is not feasible to enter a latitude and longitude.





Additional locations may be given on the events page.
In general they are not needed, but if there is a mention of ice on that day, or on the previous or subsequent days, they can be very useful.

Here is an example of a location with a bearing.


https://catalog.archives.gov/OpaAPI/media/12095758/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1952-08/atka-agb-3-1952-08-0013.jpg

Right click within the blue box, and select Location Wizard from the popup menu.

Enter the time or select it from the drop-down list.

The Type will be Bearing.

Enter the place name and bearing in the Text Input box under Place/Bearing/Passage/Other (Raw/TWYS).

If you feel more ambitious, you can look up the latitude and longitude of the place and then factor in the bearing and distance (you will find OW Find Place - by mapurves & propriome, with its link to the Resolve Bearing page, very useful).
Select Decimal under Input Mode and enter the latitude and longitude in the Decimal Type-In box.
The science team has requested that we do this when possible.




http://owtools.scienceontheweb.net/owtools/findplace.php
Click the Bearing button to bring up the Resolve Bearings page.


In this case, and in most cases, you will use position A.
Position A is used when the bearing is taken to the landmark.
Position B is used for reverse bearings taken from the landmark (E.g., position thirteen (13) miles to southwest of Princess Royal Islands).

The Resolve Bearing page has an option for factoring in the magnetic declination. Please do not use it.
Although magnetic declination can be a significant factor near the pole, it is not always clear whether the entry in the log is corrected or not, so you may be correcting a bearing that has already been corrected.
As long as you have entered the location and bearing information under Place/Bearing/Passage/Other (Raw/TWYS), the analysts can recalculate the position if necessary.



If the log page includes a synoptic observations table, the locations in that table should be transcribed.


https://catalog.archives.gov/OpaAPI/media/12104738/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/burton-island-agb-1-1955-08/burton-island-agb-1-1955-08-0010.jpg

In a slight departure from TWYS, commas are inserted for clarity because there is no way to show line breaks.
They can be omitted.



When a location has been entered, the Location X indicator in A15 will change to solid green.

Transcribing: Course and Distance

Have a look at some of Michael's earlier work!

There is no need to transcribe the course when anchored because the course is simply the direction the ship is pointed. As she swings with the currents, her head points in different directions. This is not used by our analysts because there is no displacement. Here is an example: https://catalog.archives.gov/OpaAPI/media/12096257/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/atka-agb-3-1953-07/atka-agb-3-1953-07-0072.jpg

The hours, 1-12 AM and 1-12 PM, have already been filled in for you.

Even if a number is clearly wrong, please transcribe it as written.
In you are certain that the data is in the wrong column, enter it in the correct column and use the Event Wizard to add a Transcriber Comment.




If both the By Revs and By Log columns are filled in, you only need to transcribe the By Log column.
If the By Log column is not filled in, transcribe the By Revs column if it is available.
Always transcribe the Course column.


If both the Nautical Miles and Tenths and the Patent Log columns are filled in, you only need to transcribe the Nautical Miles and Tenths column.
If the Nautical Miles and Tenths column is not filled in, transcribe the Patent Log column if it is available.
Always transcribe the Course column.

There is a column for Nautical Miles and a column for Tenths.
Please combine the values in these columns and enter them as a decimal number, as above.
For example, 3 Nautical Miles + 8 Tenths = 3.8.
Simply click in the box, note the value in the box, because it will be obscured as soon as you start to type, and then type in the value.
You can enter the data by rows (press the Tab key after entering the data) or by columns (press the Enter key after entering the data).

You may occasionally see comments in the By Log or By Revs columns.
https://catalog.archives.gov/OpaAPI/media/12103640/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/burton-island-agb-1-1954-05/burton-island-agb-1-1954-05-0019.jpg
There is no need to transcribe them.


There are a few tricky cases.
  • A change of time zones may result in clocks being set ahead causing a line with no data.
    https://catalog.archives.gov/OpaAPI/media/23655480/content/dc-metro/rg-026/559642/0002/Northwind-WAG-282-b742/Northwind-WAG-282-b742_0233.JPG
    If the weather page or the events page states that clocks were set ahead, please create an event (in one of the blue boxes) similar to this example.

     
  • A change of time zones may also result in clocks being set back causing two lines with data for the same hour.
    https://catalog.archives.gov/OpaAPI/media/23655480/content/dc-metro/rg-026/559642/0002/Northwind-WAG-282-b742/Northwind-WAG-282-b742_0222.JPG
    If the weather page or the events page states that clocks were set back, please create an event (in one of the blue boxes) similar to this example.

    Since the spreadsheet is fixed at 24 entries, we need to be a little creative and enter two lines of data into one line of the spreadsheet.
    This can be transcribed by putting pairs of numbers in a single box with a slash (/) to separate them.
    You may also need to shift subsequent rows up one so that they are correctly aligned with the hours.
    You will need to remove the slash and extra hour from the hour box manually.

     
  • Occasionally, a 'half-hour' row will have been added because of a speed or course change.
    As in the case of clocks being set back, this can be handled by putting pairs of numbers in a single box with a slash (/) to separate them.
    You will need to remove the slash and extra hour from the hour box manually.

Transcribing: Ice

All mentions of ice in the log should be transcribed in either the blue events box below the weather grid or the one covering the events on the events page.
Remember that if you transcribe data outside the blue events boxes, the transcription will not be saved.

Right click to select a cell within one of the blue boxes.
A black-bordered box appears on the page together with a menu, from which you should select Event Input Wizard.

Time can be the watch in which the event occurs (e.g., Mid to 4AM) or the time associated with the event (e.g., 2:25).
Leave this section blank if there is no time that applies.

Type is Sea Ice. Normally the Subtype is blank, but some important exceptions are listed at the end of this post.



Here is a sample transcription of the sea ice reports and the associated locations for the first watch (0-4) for 1951-08-13



For Box 1:


For Box 2:

(Because the position is embedded in the ice description, it has been transcribed here even though it should also be transcribed separately with the Location Wizard.)
and


For Box 3:

and


For Box 4:




Sometimes ice is mentioned as text on the weather page.
For example, see the Hydrographic and Meteorological Remarks section at the bottom right on this page.
It can be transcribed as a single event, as shown, or as two separate events.




You may also see ice reported in the weather grid or in specialized grids further down the page.
These should be transcribed using the Subtype Grid.
In some of these cases, TWYS has to be taken with a grain of salt. ;)

Ice mentioned in the weather grid on this page can be transcribed as:

It is counter intuitive, but you need to click in one of the blue event boxes to transcribe this data.


The mention of ice at the bottom left on this page can be transcribed as:



The mention of ice at the bottom left on this page can be transcribed as:



Ice mentioned in the synoptic grid on this page can be transcribed as:


On rare occasions, the Zone Time of Synoptic Observation (column 1) is not filled in.
In that case, enter the Time GCT (column 6) preceded by GCT.




Use the Subtype Elsewhere when you are transcribing a report of ice that is in a different location than the ship's.
This occurs when an ice report from another ship has been entered in the log (E.g., "SS Silverwave reports ice south of Wrangel Island").



We have been asked whether logging ice reconnaissance flights would be helpful.
For example, see the 0400-0800 watch on this page.
If there are good ice reports in the log it is not necessary.
However, if there are no other indications of ice in the log it might be useful.
If you choose to transcribe ice reconnaissance flights, use Type Sea Ice and Subtype Reconnaissance.



During times when the ship is not in icy waters, it is not useful to enter reports of "No ice".
However, during times when the ship is in icy waters, comments about the absence of ice may be useful.
As when you report ice, use Type Sea Ice and leave the Subtype blank.

Transcribing: Sailing Information

On the events page, it would help Michael plot the ship's positions if you record when the ship stops or starts moving and any course summaries.

A stop may be recorded as: anchored, moored, lying to, stopped, hove to, etc.
A start may be recorded as: got underway or simply underway, proceeding, stood out, standing down, etc.
Stops of less than about two hours can be ignored.
There is no need to record comments, such as anchored as before, anchored, underway as before, and underway, that do not reflect a change.
It may not always be clear whether or not the comment indicates a change.
However, an extra entry (which can be filtered out) is better than a missed entry.

There is no need to record course changes!



Right click to select a cell within the blue box.
A black-bordered box appears on the page together with a menu, from which you should select Event Input Wizard.
Remember that if you transcribe data outside the blue events boxes, the transcription will not be saved.

Time can be the watch in which the event occurs (e.g., Mid to 4AM) or the time associated with the event (e.g., 2:25).

Type is Sailing Info.



For Started, entering the Event Text is optional.



For Stopped, the text is requested because some of the terms have different meanings:
  • Anchored means that the ship remains in a fixed position.
  • Lying to means that the ship is moving with tide, current and wind.




On rare occasions, mainly at the end of a watch, you will see a course summary in the log.
That is very helpful when trying to plot the course.


Remember: There is no need to record course changes.

Transcribing: Weather records

You should transcribe any weather information that appears in a red box.
Weather data that is not in a red box, such as Clouds Ceiling, will not be saved.

The course and distance only need to be transcribed once, so if they were transcribed during the Ice Hunting phase there is no need to do it again.
See Transcribing: Course and Distance for more information.

Any mentions of sea ice on the weather page should be transcribed.
See Transcribing: Ice for more information.

The hours, 1-12 AM and 1-12 PM, have already been filled in for you.

Even if a number is clearly wrong, please transcribe it as written.
In you are certain that the data is in the wrong column, enter it in the correct column and use the Event Wizard to add a Transcriber Comment.




https://catalog.archives.gov/OpaAPI/media/12104460/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/burton-island-agb-1-1955-04/burton-island-agb-1-1955-04-0026.jpg
(Note: Format Cells was used to try to make the numbers stand out.)

Simply click in the box, note the value in the box, because it will be obscured as soon as you start to type, and then type in the value.
You can enter the data by rows (press the Tab key after entering the data) or by columns (press the Enter key after entering the data).

This log type separates cloud form into low, middle, and high.
Just enter all the cloud codes into the single box with spaces in them.



If you have chosen to enter the weather data for ships with this log format, use Bob's Sea Surface Temp Wizard to transcribe the Sea Temp. Surf. in the box at the bottom left.
The other sea data in this table should be ignored.



Quote from: philip.brohan
Please encourage people to do both Water Main Injection and Sea Temp Surf as two separate entries.

 The traditional way to measure sea temperature is to throw a bucket over the side to get some sea and stick a thermometer in the bucketful. Round about the middle of the twentieth century mariners mostly stopped doing this and just recorded the temperature of the sea-water they were pumping into the engine room for cooling instead. These two measurement methods don't give quite the same temperature and the difference is a major headache for estimates of global warming - it's hard to tell whether temperature changes seen in this period are real changes in the temperature of the sea-surface, or just artifacts of ships changing their measurement technique.
If you are really curious see: http://journals.ametsoc.org/doi/pdf/10.1175/1520-0450%281963%29002%3C0417%3AASOTQO%3E2.0.CO%3B2.



There are a few tricky cases.
  • A change of time zones may result in clocks being set ahead causing a line with no data.

    If the weather page or the events page states that clocks were set ahead, please create an event (in one of the blue boxes) similar to this example.

     
  • A change of time zones may also result in clocks being set back causing two lines with data for the same hour.

    If the weather page or the events page states that clocks were set back, please create an event (in one of the blue boxes) similar to this example.

    Since the spreadsheet is fixed at 24 entries, we need to be a little creative and enter two lines of data into one line of the spreadsheet.
    This can be transcribed by putting pairs of numbers in a single box with a slash (/) to separate them.
    You may also need to shift subsequent rows up one so that they are correctly aligned with the hours.
    You will need to remove the slash and extra hour from the hour box manually.

     
  • Occasionally, a 'half-hour' row will have been added because of a speed or course change.
    As in the case of clocks being set back, this can be handled by putting pairs of numbers in a single box with a slash (/) to separate them.
    You will need to remove the slash and extra hour from the hour box manually.

Transcribing: Events

For most log books, there are two blue events boxes.
One is below the weather grid and the other covers the miscellaneous events page.
Remember that if you transcribe data outside the blue events boxes the transcription will not be saved.
For example, if you want to transcribe the name of the commanding officer at the top of the page, you need to right click within one of the blue events boxes rather than on the officer's name.
You can click anywhere inside the blue box, but you will probably find it less confusing if you click near the information you are transcribing when possible.



Right click to select a cell within the one of the blue boxes.
A black-bordered box appears on the page together with a menu, from which you should select Event Input Wizard.

Time, Type, and Subtype all have drop-down menus, but they also allow you to enter text.

Time can be the watch in which the event occurs (e.g., Mid to 4AM) or the time associated with the event (e.g., 2:25).
Leave this section blank if there is no time that applies (e.g., for the sick list).

Type categories are: All, Animals, Other, People, Refueling, Sailing Info, Sea Ice, Ships, and Transcriber Comment.
The items that should be entered in these categories are explained below.
Any mentions of Sea Ice should be transcribed.
Transcribing any of the other types of events is optional.

If there is a Type that you think should be added, please post a note in the forum.
It is possible to enter a new Type, but keep in mind that doing so might make things harder to find, rather than easier.
If you do enter a new Type, please post a note in the forum.

The Subtypes available depend on the Type selected.
There are a few Types that do not have Subtypes, and even when there are subtypes you don't always need to use them.

As with Types, if there is a Subtype that you think should be added, please post a note in the forum.
If you enter a new Subtype, please post a note in the forum.



All
Use this to indicate that you are transcribing all the events on the page, either as a single entry or split into watches (the latter is easier to check and correct!).
To help the science team, please create separate Sea Ice events for each mention of sea ice.

Animals
  • Fishing/Hunting
  • Sighted
  • Transported
  • Pet

Other
For example:

  • Instruments
    Include here comments about weather instruments (e.g., dry bulb thermometer found to be reading one degree too high).
  • Astronomical
  • Aurorae
    Mentions of aurorae are used by the Solar Stormwatch researchers to study historical solar activity.
    Old Space Weather: sightings of aurorae and sunspots
  • Ocean/Seaweed/Plankton
    Include here mentions of rough seas, sightings of kelp and other seaweed, and discolored or luminescent patches of sea.
  • Weather
    This is for text descriptions of the weather.
    Such text descriptions will not be needed in the near future, so it is probably not worth transcribing ordinary watch entries (e.g., Light westerly airs, mostly cloudy).
    However, it may be worth transcribing unusual or extreme weather.
  • Volcanic
    Several groups are using our observations to update their records of historic volcanic activity.

People
One or more people (and ships), named or unnamed, may be included in a single entry for the watch in which they appear.
If there are multiple names separated by text that you don't wish to include, put the names on separate lines.
For example:


In general when transcribing people the subtype should be left blank.
  • Ship
    Use this subtype to indicate that one or more ships are mentioned in the transcription (e.g., Philip Wood, Lds, and Kevin Brohan, Sea, were transferred to the USS "Enterprise")
    In this case a Type of Ships with a Subtype of People could also be used. It depends whether you want to emphasize the people or the ships.

Refueling
  • Coal
  • Oil
  • Other

Sailing Info
  • Stopped
  • Started
  • Summary
See Transcribing: Sailing Information for more information.

Sea Ice
In general when reporting sea ice the subtype should be left blank.
  • Grid
  • Reconnaissance
  • Elsewhere
See Transcribing: Ice for more information.

Ships
One or more ships (and people), named or unnamed, may be included in a single entry for the watch in which they appear.
If there are multiple names separated by text that you don't wish to include, put the names on separate lines.
In general when transcribing ships the subtype should be left blank.
  • People
    Use this subtype to indicate that one or more people are mentioned in the transcription (e.g., Philip Wood, Lds, and Kevin Brohan, Sea, were transferred to the USS "Enterprise")
    In this case a Type of People with a Subtype of Ships could also be used. It depends whether you want to emphasize the people or the ships.

Transcriber Comment
At long last we have a way to add our comments to log pages!
  • No Weather or Events
    This can be used to indicate pages where there is nothing to transcribe (for example, instructions for filling out the log).
  • Bad Scan
    Use this to indicate faulty scans.
    It is probably best to report bad scans in the forum too.
  • Date
    Use this to make a note that you corrected the date or to make a comment about the date.
  • Inserts
    Use this to indicate the presence of inserts.
  • Sea Ice
    This can be used if you want to make a comment about sea ice.
  • Location
    Use this to make a note that you corrected the location or to make a comment about the location (for example, the noon location is given as Tolstoi Point but it is really Cape Tolstoi).
  • Weather Record
    Use this to make a note that you corrected the weather data or to make a comment about the weather data.
  • People
    You can use this to summarize events in the log concerning people. TWYS is not required here.
    You can also use it to provide supplementary information about people.
  • Ships
    You can use this to summarize events in the log concerning ships. TWYS is not required here.
    You can also use it to provide supplementary information about ships.
  • TimeChange
    Use this when clocks are set ahead or set back resulting in the loss or the gain of an hour of weather data.

Additional Information


Warnings

Do NOT use Version 5.4.x of LibreOffice.
If you have installed it, you will probably need to redownload the spreadsheet after installing Version 5.3.x of LibreOffice
Update: Version: 5.4.4.2 (x64) appears to work correctly, but Version 5.3.x is still recommended.

If you are in a country that uses a comma rather than a period as a decimal separator, you may see some problems.
Go to Tools -> Options, select "Language Settings", then "Languages" and change the locale setting to English (USA).


Downloading

The National Archives site can be very slow at times.
You may find it less frustrating to download multiple pages before starting to transcribe (Bob's program checks to see if the page has already been downloaded before downloading).
For example:
  • If you are working on Burton Island 1954, you can start from the forum or from the tracker.
  • To download pages for April select the National Archives link https://catalog.archives.gov/id/12103547
  • Right-click on the download icon and then select Open Link in New Tab, or its equivalent, from the pop-up menu.
  • A new tab will be created and you will see the link:
    https://catalog.archives.gov/OpaAPI/media/12103547/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/burton-island-agb-1-1954-04/burton-island-agb-1-1954-04-0001.jpg?download=true
    This page will download automatically.
    Note that I started with the first page. You can scroll through the National Archives display to choose a different starting point.
  • From then on, all you need to do is change the page number to download other pages:
    https://catalog.archives.gov/OpaAPI/media/12103547/content/arcmedia/dc-metro/594258-navy-deck-logs/00003/burton-island-agb-1-1954-04/burton-island-agb-1-1954-04-0011.jpg?download=true

Automated Download


Going back to a page

If you want to continue transcribing but you also want to be able to go back and edit an earlier page, save the spreadsheet, exit, make a copy of the spreadsheet, and then rename the copy (e.g., Burton_v1p820 - Jul 17 WR.ods).
Don't upload the XML file until you are finished with the page. In the future, Bob hopes to allow the system to read in the XML file and so that you can update it.


Customizing

There is a zoom control at the bottom right. You may find it helpful to shift between an overview of the page and a closeup of the data you are reading or transcribing.

It is possible to change your entry text's font size and color, and the position of the entry within the box.
It is also possible to change the color and thickness of the cell's outlines. You may find these changes make transcribing easier.
Select a cell by left clicking in it or select a block of cells by left clicking and dragging.
Then either right click in the cell(s) and select Format Cells... from the pop-up menu or click on the Format drop-down menu at the top of the screen and pick Cells...
From the pop-up window you can select the Font tab to adjust the font size, the Font Effects tab to change the font color (the default is Automatic), the Alignment tab and the Vertical menu under Text Alignment to change the position, or the Borders tab to change the cell outline.

Although previous Old Weather interfaces used row-based order, many transcribers requested column-based order.
Column-based order is very convenient for cut and paste and mapurves has created macros to duplicate the entry one (CopyDown1) or two (CopyDown2) lines above the cursor.
To use these two macros, you will need to assign shortcut keys to them.
Open the Tools drop-down menu and select Customize.
Ignore the message that says: LibreOffice requires a Java runtime environment (JRE) to perform this task. Please install a JRE and restart LibreOffice.
Go to the Keyboard tab and in the Category box, select LibreOfficeMacros | Burton_v1p820.ods (the name you see may be different) | Standard | Extensions.
Then in the Functions box select CopyDown1.
Select an entry from the Shortcut Keys box, for example Alt+1, and then click Modify.
Select CopyDown2 in the Functions box and repeat the shortcut key assignment.

If your log book does not use our default times or time ranges, you can add to the default list. See Adding Times to the Event Input Wizard.

NOTE: It appears that only the left-hand Alt key works in LibreOffice Calc.

AutoHotkey can be very helpful, and its most basic features are easy to implement.


Type What You See

Here is a comment from Philip from the early days of the project:
I have mixed feelings on this issue too, but our general principle is that we don't try and fix errors and omissions by the log-keepers, and we should stick to that here. Please input exactly what is in the logs.

I know we'd get better data if we used our judgement to fix it, and it hurts to abandon that, but it's necessary. Remember that much work on oW is done by people who don't read the forum - so if we agree on special cases here we'll get inconsistent results because not everyone will see the discussion. Also, if we edit the logs we corrupt the data for some possible future uses.

What we really need to do is set up a parallel interface, so we can record exactly what is in the logs as we do today, and also record our comments and corrections, to be stored separately. We are working on this, but it's hard - for the moment please just record whatever idiocies the log-keepers come up with using the current interface, and use the forum to tell us about the peculiarities (and suggest fixes).

Thanks,

 Philip

This is still basically true except for two points:
  • Bob's system allows you to use Transcriber Comment events to add comments.
  • Philip now encourages us to correct the date or location if they are incorrect and also to convert a place name into decimal latitude and longitude. However, this is optional. TWYS is always correct.
    For more information see: Transcribing: Locations and Transcribing: Date

Updates

I just tried to enter the position of 122 59.7W and it was truncated to 122 59W.

The problem is that the limit for that box is currently 59.
Until we get that changed, if your minute field is greater that 59 put the additional time in the seconds field.
In this case transcribe 122 59.7W as 122 59 42W.
