HMS Hecla 1819-20

In 1819, HMS Hecla formed part of William Parry's first Northwest Passage expedition, spending a winter in the Canadian Arctic. Several logs from this expedition are in the ADM55 collection but in this case we have taken meteorological observations from a published account of the expedition instead.
We have then converted these data into the standard IMMA format for analysis and archiving.

Analysis

 Comparing the observed sea temperatures and air temperatures with typical values for the recent past (1961-90 normals) give a picture of the weather in the Canadian Arctic in 1819-20 - an area where no observations were previously available. (Detailed analysis .)
