Crossovers (2)

oldWeather has its own venue for high-quality science gossip, but in the late nineteenth century there were no internet forums; instead they had a printed magazine: Hardwicke’s Science Gossip: A Monthly Medium of Interchange and Gossip for Students and Lovers of Nature.

Today we’d call those ‘Students and Lovers of Nature’ scientists, so our friends at the Zooniverse have set up another transcription project, to read Science Gossip and related magazines, and find out what the citizen scientists of 100 years ago were interested in.

There is one thing in particular that we are also interested in – it’s a safe bet that the pages of those magazines contained information on the weather of the time; comments and perhaps original observations. At oldWeather we specialise in ship’s logbooks, but we are not fussy, and we value weather observations from any source. So we’ve added another tag to this new project for marking pages: #oldweather for any weather observations that turn up.

Thanks to @VanHyningV, @SiobhanLeachman, our own Jil, and the whole Science Gossip project community, for this Zooniverse/documentary records/historic weather crossover.

Florence Augusta Merriam Bailey was an eminent ornithologist round about a century ago. The Smithsonian have her diary from 1887, and are running a volunteer project to transcribe it. Despite the strong hints given in the printed page headers of her diary, Florence rarely included weather observations, but there is at least one:

Minus 26 degrees (presumably F), and down to minus 30 in the valley. That’s pretty cold even for New York state (where Florence was at the time). Why so cold? Now, that’s something we can help with, with our rich collection of historical observations and renalysis. I don’t usually do forecasts (there’s another part of the Met Office for that), but as this one’s for 128 years ago maybe we can stretch a point:

Forecast for Monday, January 3rd, 1887: The high pressure currently over the central United States will strengthen and move eastward, bringing clear skies, northerly winds, and very cold weather.

A forecast for Florence Bailey in 1887: Uses data from the Twentieth Century Reanalysis (esrl.noaa.gov/psd/data/20thC_Rean/ - version 2c) and shows the places where we have observations (yellow dots) sea-level pressure anomalies (contours: solid=low pressure and dashed=high), and temperature anomalies (red=unusually hot, blue=unusually cold).

A history of the world in 1,399,120,833 observations

Locations of the weather (surface pressure) observations being used to reconstruct global weather and climate: Observations coverage (1851-2008) in version 3.2.9 of the International Surface Pressure Databank (that used in the Twentieth Century Reanalysis version 2c).

There’s a lot of history hiding in even purely scientific datasets. This movie shows just the locations of the 1.4 billion observations in the International Surface Pressure Databank (1851-2008), and in it I think I can see:

  1. The constraints on sailing-ship trade routes imposed by the global wind fields.
  2. The transition from sail to steam in shipping (late nineteenth century).
  3. The opening of the Suez canal in 1869 (01:30).
  4. The Famous Arctic voyage of Nansen’s Fram (03:20).
  5. The heroic age of Antarctic exploration (starting at about 04:00).
  6. The opening of the Panama canal in 1914 (05:10).
  7. The first world war (05:10).
  8. The second world war (07:00).
  9. Major administrative changes in India (08:00).
  10. The introduction of drifting buoys (1978: 10:20)
  11. And, sadly, a reduction in observations coverage in the last couple of decades as participation in the Voluntary Observing Fleet declines.

Of course these observations are not all that were made. Many more historical observations exist (on paper, or in restricted access collections), but these are the ones that are currently available to science. The process of rescuing the observations has also left its mark on the coverage – including right at the beginning of the video, where the coverage of ship observations reduces sharply in 1863 – the end of Matthew Fontaine Maury‘s pioneering data collection work. Various subsequent rises and falls in coverage result from the work of many other scientists and teams; including, of course, a large group of Royal Navy ship observations in the period around the First World War (starting about 05:00) clearly distinguishable just from their locations, as Naval ships move in a quite different pattern from commercial shipping. (Our US Arctic ships are not in this database yet – they will be in the next version).

A centennial: The Battle of the Falkland Islands

oldWeather forum moderator Caro has been showcasing the history in our logs, by tweeting, every day, excerpts from the logs of exactly 100-years ago (follow along here). The terse style of the logs is a good match for Twitter, but on some days so much happened that we’d like to go into more detail. December 8th, 1914 was such a day, so Caro has written this post:

It’s been said before: oldWeather is not just about the weather. We transcribe history too and few of the historical narratives to emerge from our WWI ships’ logs can compare to the events that took place on this day, 8 December, 100 years ago: the Battle of the Falkland Islands. The logs of all nine Royal Navy ships involved ― Bristol, Canopus, Carnarvon, Cornwall, Glasgow, Inflexible, Invincible, Kent, and Macedonia ― have given our transcribers and editors first-hand accounts of one of the most important sea battles of WWI.

Back on November 1, Admiral von Spee and his German cruisers had defeated a Royal Navy squadron near Coronel, Chile. British losses were heavy; the ships Good Hope and Monmouth were lost and with them the lives of about 1600 men. Glasgow and Otranto escaped. The British Admiralty, realising the danger of the German ships escaping into the South Atlantic and disrupting the Allies’ operations along the African coast; or sailing around the Horn to attack the now almost defenceless British base in the Falkland Islands, sent a squadron to the South Atlantic to track down von Spee’s cruisers. Eight Royal Navy warships assembled at Port Stanley in the Falkland Islands on December 7. The old battleship Canopus had been set in place as guardship for Port Stanley, resting on the mud, since mid-November.

On 8 December, the German cruisers Scharnhorst, Gneisenau, Nürnberg, Dresden and Leipzig, together with three auxiliary vessels, gathered to attack the Falklands and raid the British facilities there. Gneisenau and Nürnberg detached from the rest of the German squadron and moved to attack the wireless station and port facilities of Port Stanley. The two raiders were seen by a hilltop spotter who reported their approach to Canopus, waiting out of sight behind the hills.

The logs continue the story:

  • 9.19am Canopus: Opened fire fore & aft 12” turrets on Gneisenau & Nürnberg
  • 930am Canopus: Ceased fire. Enemy retreated
  • 9.30am Glasgow: Weighed and proceeded
  • 9.50am Kent: Proceeded to follow enemy. 3 more German cruisers reported in sight, Scharnhorst, Leipzig, and Dresden
  • 10.15am Glasgow: As requisite keeping touch with enemy; squadron weighing and proceeding from Port William
  • 11.43am Carnarvon: Bristol ordered to take Macedonia & destroy transports
  • 12.57pm Inflexible: Opened fire at extreme range on Leipzig, firing 12 rounds of 12 inch, apparently making no hits
  • 12.57pm Invincible: Invincible opened fire
  • 1.25pm Invincible: Enemy’s light cruisers observed to spread to starboard
  • 1.33pm Invincible: Scharnhorst & Gneisenau opened fire
  • 1.35pm Invincible: Cornwall, Kent & Glasgow ordered to chase enemy light cruisers
  • 2.51pm Inflexible: Opened fire on Gneisenau, 15,200 yards, Invincible engaging Scharnhorst, the leading ship in line ahead
  • 3.00pm Glasgow: Opened fire & engaged Leipzig with 6″ gun
  • 3.30pm Bristol: Fired 2 rounds fore 6″ and ordered Santa Isabel and Baden, German colliers, to stop; crews ordered to abandon ships. German crews transferred to Macedonia
  • 4.01pm Inflexible: Scharnhorst listing heavily to starboard, two funnels gone, and ship on fire. Ceased firing on her
  • 4.15pm Carnarvon: Opened fire [on Scharnhorst]
  • 4.17pm Carnarvon: Scharnhorst turned over & sank bow first; cease fire
  • 5.00pm Kent: Kent proceeded in chase of Nürnberg
  • 5.30pm Cornwall: Opened fire [on Leipzig] with 6″ guns & continued action with all guns
  • 5.40pm Macedonia: Opened fire on Baden
  • 5.48pm Inflexible: Finally ceased firing [on Gneisenau]. Signalled to Carnarvon, “I think enemy have hauled down their colours”
  • 6.02pm Invincible: Gneisenau sinks. Invincible, Inflexible and Carnarvon proceeded at full speed to pick up survivors
  • 6.45pm Kent: Opened fire and finally ceased fire at 6.57pm; Nürnberg sank at 7.25 pm
  • 6.50pm Cornwall: Enemy [Leipzig] on fire fore and aft
  • 7.00pm Bristol: Macedonia ordered to remain till colliers sunk and proceed to Port Stanley with crews
  • 7.23pm Kent: Stopped and endeavoured to pick up [Nürnberg] survivors
  • 7.53pm Macedonia: Baden sank
  • 8.15pm Macedonia: Opened fire on Santa Isabel
  • 9.00pm Cornwall: Stopped; lowered port boats to pick up [Leipzig] survivors
  • 9.23pm Cornwall: Leipzig foundered
  • 9.30pm Macedonia: Santa Isabel sank

The German auxiliary Seydlitz and light cruiser Dresden escaped. Almost 1900 German seamen lost their lives; 10 British were killed.

One hundred years on, we remember all those who died at Coronel and the Falklands and in the battles to come.

Documenting World War 1 at Sea

We chose our first batch of logbooks to cover the period of the First World War, as our climate records from this period were particularly poor. This gave us not only invaluable new climate information, but also a new look at a key historical period which is about to reach its centenary.

To use our historical results, we teamed up with Gordon and Naval-History.net. In Gordon’s words: ‘Our present world has been shaped by World War 1 – as much a maritime war as World War 2. Not just the Battle of Jutland or the Allies near-defeat by the U-boats, but Mediterranean, Belgian coast, South West & South Africa, East Africa, Persian Gulf, German raiders, Atlantic convoys, North Russia.’ We need to present our logbook records so they can contribute to public and scholarly understanding of the period.

The transcribed and edited logbook records are now a major component of naval-history.net, where they are described as:

British warship log books of the World War 1 era, totalling some 300,000 pages. The logs of over 300 ships have been transcribed, and most are online. They include coverage of Battle of the Falklands, Northern Patrol, Dardanelles, East Africa, trans-Atlantic convoys, Indian Ocean, China Station, amounting to some 60-70 percent of all major warship movements 1914-18, outside of British home waters.

But they are not enough on their own, we should combine them with other sources of information. Naval-History.Net has prepared for the centenary for some years, using contemporary sources where possible and more recent research where available. Current projects include:

  1. Chronology providing the political and military background to the war at sea.
  2. Naval Operations by Corbett and Newbolt – many of the excellent plans are online including all the Battle of Jutland – and the three volume Merchant Navy histories by Hurd.
  3. Navy despatches and relevant Army despatches from the London Gazette. Also Royal Navy honours and gallantry awards by award and by Gazette date. Includes Medal index/database by name.
  4. Royal Navy and Royal Marine casualties (researched by Don Kindell working with the Naval Historical Branch (MOD)), as well as those of the Dominion Navies and U.S. Navy & Marine Corps.
  5. Royal Navy warships and auxiliaries from the invaluable “Ships of the Royal Navy 1914-1919″ by Dittmar and Colledge. Although still in progress, all warships and many of the auxiliaries are listed by name and by type/class.

Journey Plotter, or an Old Weather addiction story

[This post is from Maikel, who has come up with a new way of using and viewing the information we are collecting].

The voyage of HMS Birmingham (showing a few position errors) as seen in Journey Plotter.

The voyage of HMS Birmingham (showing a few position errors) as seen in Journey Plotter.

Having been active as an Old Weather transcriber and in editing the transcribed logs for display on Naval-History.Net, I started to be curious about the journeys of the Royal Naval ships.

Giving in to this form of Old Weather addiction, I started to create an application that could retrieve the position information for the vessels I had edited. Seeing the dry numbers being transformed into a 2-dimensional voyage on a map was such a satisfying experience, I just had to share it with others.

This resulted in Journey Plotter, a Windows application for plotting the journeys, or parts thereof, of Royal Navy ships from the World War 1 era. Journey Plotter makes use of data from original Royal Naval log-books that have been transcribed and edited by oldWeather volunteers, and then made available by Naval-History.Net. Journey Plotter also turned into a valuable tool for the log editors: Position mistakes of a vessel are easily overlooked if it’s just a number. Seeing a strange jump in a voyage makes it much easier to spot.

If you are interested in Journey Plotter, visit http://tinyurl.com/journeyplotter to learn more about it. I trust you will enjoy looking at the journeys of the Royal Navy vessels and/or have a useful tool during the editing of their voyages.

Images from Journey Plotter are now being used in some of the ship history files we’re producing: E.g. HMS Birmingham, HMS Una.

oldWeather Arctic

USRC Bear


Volunteers wanted for vicarious journeys. Bitter cold, long months of complete darkness, constant danger, safe return doubtful. Honour and recognition in case of success.

Today we launch a new fleet on oldWeather.org: the focus this time is on Arctic voyages, and the logbooks are from the collection of the US National Archives in Washington. We’ve ships from the Revenue and Coast Guard, the Navy, and the Coast Survey; and they include some famous names and some exciting voyages.

The Arctic is very sensitive to climate variability and change. This year (2012) was a record year for sea-ice: there was less sea-ice this September than for any other year for which we have good satellite records. But the satellite records only go back to 1979, and we need many more than 30 years of records to really understand how the Arctic climate behaves. This means we need to rescue the weather records of the people who travelled there – to read the logs of Arctic voyages.

If you joined in the original oldWeather, you’ll notice some differences in this new version: There are fewer ships (at least to start with, we’ll be adding more regularly), but the records for each ship usually cover many years, so we have just as many pages to read. These logbooks are also older (back to 1850 in some cases), and differently laid-out, so we’ve had to change the way you enter data: Basically it’s the same – select the location on the log page with an important record and then type the record into the pop-up box – but the details have changed. So whether you’re a new recruit or an old hand, please experiment until you get used to it – there is a tutorial to guide you, and help and encouragement on the project forum.

We’re still looking for all weather records, and anything else you read and think is interesting or notable. There will be plenty of notable historical events: the dangers of sailing through the ice add a lot of drama to the stories in the logs – whether you prefer the daring rescue by USRC Bear, ice and fire on the USS Rodgers, or the so-far-unknown adventures of less famous ships.

The transit of Venus

The weather in Exeter yesterday was best described as “ocr“, so I missed the transit this time. Fortunately, the skies were clear back in 2004, and I remember the experience of peering through a pair of binoculars equipped with a sun-filter and seeing the small black dot of Venus silhouetted against the sun.

The transit of Venus is a periodic event, and the big year was in 1769. I understand that the astronomers valued the transit as a way to get a handle on the size of the universe; but the real virtue was that it provided an excuse for the British Government to send an expedition down into the South Pacific. That expedition was commanded by James Cook, and it started the career of the greatest explorer of them all.

Of course, as a naval officer (Lieutenant, at the time), Cook kept a journal. If your eyesight is up to it, you can read his account of June 3rd 1769 in the original handwriting; but I admit that I looked up Project Gutenberg’s transcription:

Saturday, 3rd. This day proved as favourable to our purpose as we could wish. Not a Cloud was to be seen the whole day, and the Air was perfectly Clear, so that we had every advantage we could desire in observing the whole of the Passage of the planet Venus over the Sun’s Disk. We very distinctly saw an Atmosphere or Dusky shade round the body of the planet, which very much disturbed the times of the Contact, particularly the two internal ones. Dr. Solander observed as well as Mr. Green and myself, and we differ’d from one another in Observing the times of the Contact much more than could be expected. Mr. Green’s Telescope and mine where of the same Magnifying power, but that of the Doctor was greater than ours. It was nearly calm the whole day, and the Thermometer Exposed to the Sun about the Middle of the day rose to a degree of heat we have not before met with.

The ideal weather observer does not expose his thermometer to the sun (shade temperatures please), so perhaps it’s no great loss that Cook’s journal does not contain regular weather observations. For those, we must turn to the Master’s log of HM Bark Endeavour (the closest equivalent to the familiar modern-day logs). For the day of the transit, this records “Little wind and variable with fine pleasant clear weather”. I reckon that’s “Lt. Airs, Var., 1, b” in our notation. Sadly, none of the logs contain regular thermometer or barometer observations – Cook did better on his subsequent voyages – but we do get wind speed and direction reports for every day.
