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!

The next milestone/millstone is the lowest maximum sea-ice extent for
the Arctic that was 14.517 x10^6 sq km, on 25 Feb 2015 (NSIDC method),
yesterday it stood at 13.900.
Total global sea-ice yesterday was a 38 year "all-time" record minimum.
Antarctic sea-ice is likely to be also "all-time" minimum today,
reportage tomorrow.
The experts don't know what if anything (except climate change) is
linking similar tipping-point? events at both poles

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.

Maybe Norman's already seen this, but some further info on the background to
the buoy data:

There's open water about 300nm due south of the buoy whereas it should
be about 700nm at this time of year so there's not a great deal of ice
to cool down southerly winds. Even so, there would be open water west of
Svalbard to near 80N in most winters in the past so, even then it
wouldn't be too far from the warming effect of the ocean.

This warm spell has pushed the ice northwards in the Svalbard area so
keeping the extent of Arctic ice at record low levels but it may also
have the effect of reducing the chance of a record low this summer by
blocking the outflow of old ice through the Fram Strait. The conditions
off the east coast of Greenland remind me more of a typical June and
July in the 1960s, which seems to back that up that supposition.
However, I still think we're in for a record low this summer in spite of
that.

Minus 25?
Sea temperatures are between 2 and minus 2. It must have got frozen in above the ice.

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. ;-)

Just to confuse the issue further, in the Units and Terminology section in the
Admiralty Sailing Directions (Pilots) it states that 'Distances are expressed
in sea miles of 60 to a degree of latitude'. In the body of the text they then
simply refer to 'miles'.

In reports that I write in a marine context I normally refer only to 'miles'.
In that context it is implicit that I mean 'nautical miles'. This is consistent
with how distances are referred to by mariners i.e. 'miles' means 'nautical
miles'. The reason is that distances in nautical miles can easily be measured
using the latitude scale on navigation charts.
