43 years in the North

The voyages of the Bear, Corwin, Jeannette, Manning, Rush, Rodgers, Unalga II, and Yukon


Today is the fourth birthday of oldWeather, and it’s almost two years since we started work on the Arctic voyages. So it’s a good time to illustrate some more of what we’ve achieved:

I’m looking at the moment at the Arctic ships we’ve finished: Bear, Corwin, Jeannette, Manning, Rush, Rodgers, Unalga II, and Yukon have each had all of their logbook pages read by three people; so it’s time to add their records to the global climate databases and start using them in weather reconstructions. From them we have recovered 43 ship-years of hourly observations – more than 125,000 observations concentrating on the marginal sea-ice zones in Baffin Bay and the Bering Strait – an enormous addition to our observational records.

The video above shows the movements of this fleet (compressed into a single year). They may occasionally choose to winter in San Pedro or Honolulu, but every summer they are back up against the ice – making observations exactly where we want them most.

So in our last two years of work, we’ve completed the recovery of 43-ship years of logbooks, and actually we’ve done much more than that: The eight completed ships shown here make up only about 25% of the 1.5 million transcriptions we’ve done so far. So this group is only a taster – there’s three times as much more material already in the pipeline.
