I see that a buoy in the Arctic at 85.9°N 31.0°E reported a temperature
of -1°C
early on 9th Feb and +1°C late on 10th Feb. It then went back down to
-25°C
yesterday. Fascinating times!
========================
Not at 85N admittedly, but Svarlbard seems to have been significantly
above freezing for several days recently. See eg post #2760 at:
https://forum.arctic-sea-ice.net/ind...1611.2750.html
Seems to be the end of the (relatively) very mild weather in the Arctic
for now, but interesting while it lasted.
It sounds really strange to hear of above freezing temperatures that
close to the North Pole. Surely it should be like a deep freezer up
there at this time of year.
There's open water about 300nm due south of the buoy whereas it should
be about 700nm at this time of year
I thought nm meant nanometres?
I was going to type 'NM' but made the mistake of Googling to check. The
top reference I saw gave 'nm' as the abbreviation. Now I've had another
look and this is what Wikipedia says:

There is no internationally agreed symbol.
M is used as the abbreviation for the nautical mile by the International
Hydrographic Organization and by the International Bureau of Weights and
Measures.
NM is used by the International Civil Aviation Organization.
nm (the SI symbol for the nanometer) is used by the U.S. National
Oceanic and Atmospheric Administration.
nmi is used by the Institute of Electrical and Electronics Engineers and
the United States Government Publishing Office.

Considering the nautical mile is based on a numerical system that dates
back to Babylonian times, you'd think someone might have come up with an
agreed standard by now. ;-)
