Barometer changes and CORRECTIONS required to balance readings:

Description of the Instruments used in making the
Meteorological Observations recorded in the columns of the Log Book.

Barometer
The standard was a Mercurial Barometer made by Adie,
London, No. 1231, and was placed in the
State-room of the Commanding Officer.
 For convenience of observation a Holosteric Aneroid Barometer
made by T.S. & J.D. Negus, New York (without numbers) was placed
in the open air on the outside of the Cabin bulkhead and
remained there from June 25th to 4.30 PM September 25th 1879.
The entries in the Log Book between these dates are readings
of this Baromoeter: and a general correction of one tenth of
an inch (0.1") subtractive must be applied to these to make
them agree with the Standard Mercurial at similar tempera
tures.
 At 4.30 PM September 25th - 1879, the said Aneroid was
moved to within the Cabin, and set by comparison with
Mercurial Standard to a reading reduced to a temperature of
32 degrees Fahrenheit.
 At 2 PM September 27th - 1879 it was set to comparison
with Mercurial Standard to a reading reduced to a tempera
ture of 46 degrees Fahrenheit. The reading of this Aneroid was
discontinued at midnight October 31st - 1879.
 From 1 AM November 1st 1879 to Midnight January 9th 1880
the readings for the Log were made from Aneroid Barometer
No. 28051 which had been set by comparison with Mercurial
Standard to a reading reduced to 32 degrees Fahrenheit.

PLEASE could these thermometer notes go to the scientists - they include corrections to the various readings. Thank you:

Thermometers
The Standard was a Mercurial Thermometer N0. 4313 made by Green, New York.

Air Dry Bulb  Air Wet Bulb.
From June 25th to October 31st midnight, the Dry Bulb
was recorded from readings of Mercurial Thermometer N0 2009,
USN. made by JT Large, and which comparison with
Mercurial Standard requires a correction of eight tenths of
one degree (0.8 degrees) additive.  The Wet Bulb was recorded
from readings of a Mercurial Thermometer (without number)
made by JD Patten, Poultny, London, and which by
comparison with Mercurial Standard requires a correction  of
three and a half degrees (3 1/2 degrees) Subtractive.

From November 1st 1879. 1 AM to January 9th 1880,
Midnight, the Dry Bulb was recorded from readings of
Standard Mercurial thermometer made by Green, New york.

Water Surface.
These temperatures were recorded from readings of a
Mercurial Thermometer mad by JD Patten, Poultny,
London, which by comparison with Mercurial Standard
requires correction of two degrees (2 degrees) Subtractive.

Deep Sea Temperatures
At 1 fathom from the Lead. L Casella, London No 24415
At 16 fathom from the Lead. L Casella, London No 27110
At 30 fathom from the Lead. L casella, London No 25257

------------------------------------------------------
From Joan: Please note the Barometer page has been corrected to show 9th January 1880 towards the end. thank you.

I updated the Barometer page.

Beaufort scale was specifically designed to be judged by when the most common types of ship had to modify their sails.  Permanently caught in the ice, this may have come easier.  It is certainly more detailed.  And an interesting choice.

Better add the info about the air pressure as well which is relative to 32?F. They have become a manned polar drift station and act accordingly, as it seems.

They expected to get caught in ice - partly in the hope that it would drift them to the Pole or lead to open waters leading to the Pole.

I wonder how this differs from the previous routine? Perhaps the weather data were recorded directly into the ship's log rather than being copied from the meteorlogical journal?

I note also that the pressure is now given to 3 decimal places and the attached temperature is blank. Could this mean they are now entering the adjusted pressure in the log?

Inserted notes on pages of January, 10th 1880, start of vol 2 (I think).

Description of the Instruments used in making the Meteorological Observations recorded in the columns of the Log Book.

Barometer

The Standard was a Mercurial Barometer made by Adie, London, No 1231, and was placed in the Cabin. The entries in the Log Book are from reading of Aneroid barometer N 28051 which had been set by comparison ~ Mercurial Standard to a reading reduced to 32? Fahrenheit and placed in the ~ ~ Room.

Temperature.

The "Air Dry Bulb" was recorded from readings of Standard Mercurial Thermometer No 4313 made by Green, New York. So long as the temperature was above the freezing point of the Mercury of that instrument. At other times the temperature was recorded from readings of spirit thermometers, uncolored or colored as marked "clear" or "purple" ~, and indicated by their numbers. All these thermometers were made by Green New York.

The "Water at Surface" was recorded from readings of a thermometer attached to a Hydrometer Cup made by G. ~, New York, (without number) and which thermometer agrees with Standard Mercurial Thermometer No 4313.

Deep Sea Temperatures

The depth of water not being great, ~ one Casella-~ Thermometer was used. The numbers of the Thermometer ~ are written in ~ ~ abreast of the Sounding. ~ were found upon comparison to agree with Standard  Mercurial Thermometer No 4313. The Temperature at a depth of two fathoms was obtained ~ water drawn from one of the Sea ~ in the bottom ~ the ship which was quite uniformly 12 feet below ~ Surface of the water. The readings were made from ~ Thermometer attached to the Hydrometer Cup made by ~, New York before mentioned.

Specific Gravities 

Water was brought up by a ~ Water Cup from ~ greatest depth obtained. Water at 2 fathoms was obtained ~ a Sea ~ as mentioned above. The "Surface"water was obtained from about one foot below the Surface. The Specific Gravities were read from a Hydrometer ~ ~, New York. Specific Gravity ~ Fahr. ~ 1.020 to 1.031, for the greatest depth. Surface water ~ water at 2 fathoms had their Specific Gravity recorded ~ readings of a more delicate Hydrometer marked "Reinmann ~, 96 Fulton St. N.Y. Specific Gravity ~ ~F Scale ~ to 1.040.

Solar Radiation

The "Black Bulb in Vacuo" was made by Green, New York.

The "Black Bulb in Air" was made by Green, New York..

Wind Velocities

These were recorded from readings of an Anemometer marked " ~. Green, N.Y." "Signal Service U.S.A:" "10" "No. 120"

Until April 16th the Thermometer was secured in and about a lattice work box which was fastened to the Starboard ~ Rigging, and the Anemometer mounted on top of a ~ ~ to the ~ ~. On April 16th the Thermometer Box and Anemometer were removed to the ice about 150 feet from the ship and mounted on a frame work about ~ feet in height.

Please do put the whole inset transcriptions on the page they would have been on if they had fitted.

Before I took up climate science I used to work on safety assessments for (nuclear) power stations, and a main steam-line break was one of the most serious accidents we modelled. Tragedy though it was, I reckon the Concord did well - I'm amazed that more people were not killed or injured.

The barometer change is also notable - it happens before the accident, but after they have done their exercises and fired their guns. It could well be that they broke their mercury barometer doing this - they wouldn't be the first. Perhaps on another day it would have rated an entry in the log.

It's also clear that at least one of their barometers is badly calibrated (probably the replacement (aneroid)) - the measurements switch by 0.5 inches when they change instrument. I'd expect a mercury barometer to be about 0.1 inches higher than a good aneroid at 68F, but 0.5 inches is a lot. I'll be interested to see when they switch again - presumably they'll be back in port for a refit soon.

Old thread, but I noticed the Concord received another aneroid barometer on 22/07/1891.

4-8 pm watch. It's last in a larger shipment of equipment and parts and there's no mention of installing the barometer in the following days, so it might be a spare.

I'd mark it as an event but I'm not actually transcribing this page, just snuck a peek (I transcribed the weather log for this day, and then it skipped to the next weather log, so I assume the event log got its third pass before I got to it).

edit: Accidentally linked the wrong log page, fixed.

The Yukon barometer during the 1917 voyage appears to be biased on the low side. The average reading is in the mid 29's and it is not unusual for it to drop below 29. Here is a good example - a reading of 28.33.

For anyone using or parsing this data:

It appears that on September 28, 1913 (http://oldweather.s3.amazonaws.com/ow3/final/USCS%20Patterson/Book%2013/IMG_6346_0.jpg), the wet bulb thermometer was broken and replaced with a new one.

I suppose theoretically, that should not matter.  But given that it's 1913, and I have no idea how precise instrumentation was back then, it may make a difference in the readings.

Post by: Janet Jaguar on January 17, 2014, 05:07:25 pm
Just to clarify that I'm doing this right...

On this page: http://oldweather.s3.amazonaws.com/ow3/final/USCS%20Patterson/Book%2025/IMG_7557_0.jpg

at the point where the Patterson sets sail, the log keeper suddenly starts recording a Fahrenheit temperature in the column where they've been recording wet bulb temperature (in Celsius) for quite a while.  And from previous and future log pages, I know that the Fahrenheit reading is used for surface water temperature.  (You'll also notice that the 4 am and 8 am readings are done as per normal - not like the records for the rest of this day)

So, I'm recording the Fahrenheit number in the surface column, and not the wet bulb column as TWYS would have me do.

ETA

Actually, I'm now officially confused about what to do - which maybe means I should revert to TWYS and let smarter people figure it out??

The next page: http://oldweather.s3.amazonaws.com/ow3/final/USCS%20Patterson/Book%2025/IMG_7558_0.jpg has entries from 1-7 am with a celsius reading in that column.  From 5-7 they also specify a Fahrenheit reading specifically labeled surface temp.

Then from 8am - 8 pm that 2nd column is in Fahrenheit, and from 9pm - mid it's back to Celsius.

SO..

Does anyone know if it's easy to swap thermometers around in the devices they use for measuring these things, or is it more likely to be a case of column confusion by the logkeeper?
That whole thing is so confusing, I'd stick with strict TWYS and ask the mods (me!) to tell Philip that the log keeper made a mess out of things that his analysts will have to figure out.   :-\

Consider the notice to Philip as done.
Page recorded as normal while working in Alaska:  (1st col in F for surface temp, 2nd col in C for dry bulb, 3rd col in C for wet bulb)

On the high seas, they abandon anything like time zones and go by "sun time" a.k.a. "apparent ship's time" or some variation of that.  So a traveling ship needs to continually update the mechanical clocks that control the watch periods.  Anytime they are in national border waters, they usually switch over to local time.

The Albatross lost thermometer no. 98247 on 03/03/1904. However, this isn't either of the two listed on the instruments page (Nos. 6085 and 6086), so I presume that no. 98247 was used solely in connection with the scientific dredging/sounding studies (which involved taking temperatures at the sea floor), and probably won't affect the weather records - if nothing else, they kept recording temperatures normally!

As mentioned in the Concord discussion, mercurial barometer (and attached thermometer) readings were recorded in the logs, in addition to what I assume are aneroid readings, beginning March 9, 1907. They appear twice a day for about a month and then sporadically after than until about mid May. The recorded aneroid readings appear to be unusually low throughout that period and as far as I have so far recorded (June 18, 1907). I have transcribed both the mercurial and aneroid readings for 20 days in the attached Excel file as Philip said he might use this information to adjust barometer data. For these 40 observations that I transcribed the difference between the mercurial and aneroid readings varies between about .55 and .75 inches.

That graph is scary - no wonder they kept recording both, they are totally out of tune in ways that are not just a calibration issue.
Title: Re: Barometers, Instrumentation and Specifications by Ship - Phase 3
Post by: Craig on March 08, 2015, 04:28:28 pm
The graph does look scary, Janet, but it looks worse that it is because I set the minimum Y axis to .55 rather then zero. 80% of the differences from the mean bar difference are less than .02 inches. It's the 7 or 8 outliers that make it look so bad. Using a  + .67 inch correction to the aneroid may not be too bad.
Title: Re: Barometers, Instrumentation and Specifications by Ship - Phase 3
Post by: Janet Jaguar on March 08, 2015, 04:37:50 pm
I don't think the log keepers did any of the mathematical corrections - I think they just saw the inconsistencies in the raw data and weren't sure which instrument to trust.
Title: Re: Barometers, Instrumentation and Specifications by Ship - Phase 3
Post by: Craig on March 08, 2015, 05:30:07 pm
I think they may have especially found that the aneroid was too low, Janet. It has been consistently, with a few minor exceptions, below 29.5 for half a year so far. The average aneroid reading for the numbers in my spreadsheet is 29.42 compared to 30.09 for the mercurial.  That's the .67 inch "correction" I was referring to.

A plus or minus .02 inch variation on the mean difference (between the two barometers) doesn't seem too bad when you look at Michael's comparisons between the Concord and other ships it meets (in earlier years).
Title: Re: Barometers, Instrumentation and Specifications by Ship - Phase 3

I agree with the "too low" - and from the newer instrument, that's a sign of unreliable until they understand how to adjust.

You're only at the end of August 1900?
I'm in the middle of October 1900 - so I must have passed you even though I only do five pages per day on this ship.
And I'm planning to do make the Concord my next primary target once I finish the Patterson, which will take a month at the most.

As an additional confirmation of the instruments page from April 1904, the barometer on the Albatross was located in the pilot house in August 1904 - they couldn't read it when the pilot house floor was being painted 24-27/08/19043

Barometer sent ashore for adjustment.  No readings after 1pm.

No mention was made of the actual adjustment, but it was minor enough that I can't see much difference (maybe slightly higher now).

Next day they are using two barometers with very different readings, the usual one jumps up 8am- 9am from 29.69 to 30.16 (.39) and the first reading from the Merc at 9am shows 30.32.
From then on the Merc shows .14 higher most of the time over the usual one (Aneroid) which I am logging.

From 1st Feb 1894 they start recording Aneroid barometer readings as well as the normal (presumably mercurial one) but not on every line. No mention in the remarks about why they are doing this. I've been putting the aneroid ones in as an extra WR, hope that's correct.

http://oldweather.s3.amazonaws.com/ow3/final/USS%20Thetis/vol017of024/vol017_143_0.jpg
Part way through May 29th 1894 they start to just use the aneroid - 'The mecurial barometer being reviewed'

It happens around here (Western Lake Ontario, US/Canada - South Shore) somewhat often in the summer. The lake is very deep and if we get a good East wind it will run over 400mi (480km) of lake and 'flip' the lower, colder layer up. Lake surface temps along the shore can go 70 to 40F (21 - 4 C) in a few minutes!! Gets us some REAL interesting fogs when we are out sailing!!

On August 29th, 1889, Jamestown switched to an aneroid barometer at 10 am:
https://oldweather.s3.amazonaws.com/ow3/final/USS%20Jamestown/vol061of067/vol061of067_155_0.jpg

This seems to last at least until the end of the logbook (October 12th) - the barometer column isn't always explicitly marked as aneroid, but I think we can assume it was like that the whole time.

EDIT: I checked the next log, and it's still aneroid on October 14th: https://oldweather.s3.amazonaws.com/ow3/final/USS%20Jamestown/vol062of067/vol062of067_010_0.jpg
Will keep an eye out for any more changes when I get to that log.

Thanks Maikel but mine was for 1903.
I was a bit lazy and I did not want to look back through all the pages to find 1903, twice is better than none.
