Guide to THE TABS: the headings, entering data, notes for transcribers and what to enterThe headings
The tab headings are Date
, Weather Observation
, Sea Ice
When you open the first entry box on a page, the Date tab will be active (orange)
To open any of the other tabs, simply click the name of the tab you require and it will become active (orange).
Open a separate entry box for each piece of information
that you wish to record.
You need to enter and OK in separate entry boxes the DATE, LOCATION (lat/longs or Port Name), and each set of WEATHER OBSERVATIONS.
Follow the same procedure for each item you choose to include on the other tabs.
For instance, if there are two named ships that you wish to record on the MENTIONS tab, use a separate entry box for each of them.
Open an entry box to enter the details of the first ship, then click OK to save; open another entry box to record the details of the second ship and save that too.
(See the illustration of two completed and saved pages below.)
To recap: you need to record and save one log entry or set of values, on one tab, at a time
Only the entered data visible in the entry box, on the active tab, will be saved when you click OK.
Click 'I've finished with this page' when you have entered all the available information on the page.
Your weather page could look like this when finished: and your Miscellaneous Events page could look like this:
The data for a single day are usually spread over two pages
of the logbook.
The data for the Weather Observation and the Location tabs, and in some logs, Refueling, usually appear on the first (left hand) page.
The second (right hand) page is where you will usually find the data that can be entered on the Date, Animals, Mentions, Sea Ice and Events tabs.
Data for Date, Location and Weather Observation are required.
Animals, Refueling, Mentions, Sea Ice and Events data are optional but if you choose to omit them, you will miss out on a lot of fun ...
and the opportunity to record valuable information for use by both scientists and historians.
Notes for transcribers
- If you prefer to use your keyboard, rather than clicks, to move from one field to the next, use the Tab key.
Use the arrow (cursor) keys to move up and down the drop-down menus, then Enter when you have made your choice.
The Enter key may also be used to OK a complete set of weather entries.
- If you find a ditto (repeat) symbol, such ", ', or any other kind, please enter it as ". You do not need to spell out the entry that has been dittoed.
- A dash on its own in a column may be transcribed as - (hyphen/minus symbol) or the field may be left blank.
- If you cannot even guess at a letter, a groups of letters or a whole word, indicate this by using a tilde or tildes: ~, ~~ etc.
Please do not use question marks for this purpose.
- If there is no written information on a log page, click 'I've finished with this page' and move on.
At the beginning and end of logs you may need to do this several times.
- Do not be alarmed if the temperature information in the timeline on the right of the screen is jumbled
or if the map shows the wrong location for your ship or disappears altogether.
The map and timeline are a visual representation of the data you enter and are for your information only.
- The important thing is to put the entries in the right place. Accuracy is more valuable to this project than speed.
- Again, please do not 'correct' entries which seem to be wrong; similarly, please do not add anything that has not been written in the log.
What to enter
Enter the date in the format suggested: dd/mm/yyyy
. For example: December 5th, 1900 = 05/12/1900.
Make as many Location entries as you wish but please note the following.
The order of preference is as follows:
- Noon Observed latitude/longitude
-- This is the one that our scientists need most. If it appears on your log page, please enter it.
- Noon Dead Reckoning latitude/longitude
- Other time Observed latitude/longitude
- Other time Dead Reckoning latitude/longitude
- Port Name
- Place Name
Only latitude/longitude entries will move the ship marker on your map.
Please enter latitudes/longitudes as they appear in the log.
You may see, for example, N45 00 W45 00 or
45 00N 45 00W. Either format is accepted.
You may even see an Observed latitude and a Dead Reckoning longitude, or single latitudes or longitudes.
Enter these individually as they appear on the log page.
Including degree, minute and second symbols is not necessary. Only the letters and numbers are required, separated by spaces:
eg 45 00N 45 00W.
However, for forms such as 45.00N or 45o
00'N, if you are unsure, enter these as they appear.
A lower case 'o' is sufficient for a degree symbol.
If you find a fraction, eg 147o
'E or a decimal form eg 147o
55.5'E (both of these represent 147 degrees 55 minutes 30 seconds E), the science team prefers that you enter them in the form 147 55 30E.
If the latitude/longitude has been based on bearings, such as Conical Rock 76 02N 68 49W, enter this as Observed 76 02N 68 49W.
The other options on the Location tab are Port Name and Place Name.
Choose Port Name
Cape Wankarem, for instance
for places where the ship has anchored.
Choose Place Name
for sighted towns, cities, rivers, lightships, lighthouses, islands etc.
If a bearing is given, please include it as part of the Place Name.
Location data, usually found at the top of the log page, such as voyages 'from A to B' and 'At sea' should also be entered under Place Name.
Please enter the sets of weather data for every hour that has been recorded. There can be up to 24 sets or more while the ship is at sea.
There are usually six or seven while the ship is in port.
The values to be entered can be found in the corresponding columns on the log page (the wording varies slightly from log to log):
Hour = Hour
Wind Dir = WINDS/Direction
Force = WINDS/Force
Bar Height = BAROMETER/Height in inches
Ther Attached = BAROMETER/Ther att'd
Dry = TEMPERATURE/Air Dry Bulb
Wet = TEMPERATURE/Air Wet Bulb
Water = TEMPERATURE/Water at surface
Weather Code = State of the Weather by symbols
Cloud Code = Forms of Clouds by symbols
Clear Sky = Proportion of Clear Sky in 10ths
If any of these values have not been filled in on the log page, leave the field blank and move to the next one.
Some logs do not have all these columns.
Some have a cloud cover column instead of a clear sky column. You should still enter the figure that is given.
It is not necessary to add am or pm to the Hour
for Wind Dir and Cloud Code
appear when you type the first letter of a wind direction or cloud form.
In addition to directions, Wind Dir also has Calm, Light Airs and Var (for variable or various).
If the entry that you are transcribing does not appear in the menus, please type it as it appears on the page.
This could be a wind direction such as NExE, or a cloud form such as Sc-Cs.
It is quite OK to choose N from the Wind Dir menu, for instance, when the log entry is North spelled out.
Similarly, from the Cloud Code menu, you can choose A-Str when the log entry is Altostratus or As, for example, or Cum-Nim for a Cumulonimbus or Cb log entry.
If you are in any doubt, again, type what appears on the page. That way, you cannot be wrong!
The range for barometer heights
is about 27.05 to 31.50, so take another look if the reading seems at first sight to be 81.50.
A reading of 28.90, for example, could appear in any of the following forms: 28.90, 28-90, 28 90, 2890, or even .90 (when part of a series of similar readings).
Please enter the number exactly as it has been recorded.
These are the Weather Code letters
that you are likely to see:
clear blue sky
drizzling or light rain
wet air, without rain
gloomy, or dark stormy-looking sky
misty or hazy weather
passing showers of rain
rainy weather or continuous rain
snow, snowy weather or snow falling
ugly appearance or threatening weather
wet or heavy dew
A full list of Beaufort weather codes can be found here
You may find references to animals such as penguins, bears, seals or whales.
< You may find these mentioned too!
Please enter all animal references on this tab, giving numbers if the log keeper has recorded them.
If you find a record of the amount of coal, oil or other fuel that has been brought on board your ship, please enter it here.
Records of the amount of fuel used and/or remaining may be entered on the Events tab if you wish to record them.
The options here are Person or Ship. Please add also the context in which these people or ships are mentioned.
Person | Name = Petersen (S) Context = Placed Petersen (S) in double irons for safe keeping upon anchoring
Ship | Name = USS Oregon Context = Exchanged distinguishing pennants with USS Oregon at 9:05
If you wish to enter mentions of unnamed people or ships, put them on the Events tab.
Ice features heavily in the Arctic logs, as you would imagine, and we would like you to enter any records of it on this tab.
An example: Harbor full of loose ice with pack outside.
Kevin Wood, of the Old Weather team, explains why mentions of ice are so important:
Any information about sea ice is of serious interest for several reasons. We are working on an Arctic sea ice reanalysis for the period 1850-on based on the Applied Physic Lab's latest sea ice forecast model. It will be forced by specific large-scale atmospheric fields (I.e. barometric pressure) from global reanalyses. A crucial issue is - will the result have an appropriate characterization of the real Arctic sea ice environment - especially thickness? Since we do not have anything remotely close to a comprehensive long period sea ice data set like ICOADS we must build one that is good enough for validation/verification if the experiment is to be useful. And here is an essential question we hope to answer: why is the Arctic sea ice disappearing at a rate 2 or more times faster than the latest climate models project? Sea ice thickness and the rate of ice advection out of the Arctic via the trans-polar drift are also tied together.
Here you may enter any other items such as naval actions, natural phenomena, astronomical observations or social occasions; anything that you find interesting can be included.
We particularly encourage you to enter mentions of sunspots, aurorae, erratic compass bearings and unusual radio reception
on this tab.
In addition, remember that if you cannot decide on which tab an entry belongs, put it here. This is the catch-all tab.
