A new ensemble prediction from an ice - ocean model was submitted by Zhang for the July outlook and the new
sea ice thickness map for September 2010 still shows ice remaining in Lancaster Sound.
Examining the CyroSat - 2
sea ice thickness map for this spring, Stefan Hendricks further explained: «The Transpolar Drift Stream, a well - known current in the Arctic Ocean, will be carrying the majority of the thick, perennial ice currently located off the northern coasts of Greenland and Canada through the Fram Strait to the North Atlantic.
However, as you'll see by
the sea ice thickness maps below, there may be good reason for the lack of ringed seal lairs, and a general lack of seals except at the nearshore lead that forms because of tidal action: the ice just a bit further offshore ice looks too thick for a good crop of ringed seals in all three years of the study.

After compiling 10 floe - scale
maps of the
ice from the Weddell, Bellingshausen, and the Wilkes Land regions of the continent, the researchers found that the
sea ice thickness tended to be highly variable, with many ridges and valleys, they report online today in Nature Geoscience.
If we compare the
ice thickness map of the previous winter with that of 2012, we can see that the current
ice conditions are similar to those of the spring of 2012 — in some places, the
ice is even thinner,» Dr Marcel Nicolaus,
sea ice physicist at AWI, said today at a press conference during the EGU General Assembly in Vienna.
So what we need is detailed topo
maps of the bed and
thickness of the GIS, and to work out a
map of the «net buoyancy», or some such (i.e. total
ice area density subtracted from the area density of a hypothetical column of water resting on the bed and extending up to
sea level).
Now, the complete 2010 — 11 winter season data have been processed to produce a seasonal variation
map of
sea -
ice thickness.
In June 2011, the first
map of Arctic
sea -
ice thickness was unveiled, using CryoSat data acquired between January and February of that year.
After nearly a year and a half of operations, CryoSat has yielded its first seasonal variation
map of Arctic
sea -
ice thickness.
As surface temperture is altitude dependent one might have thought the first thing to check would be a
map, as the arctic
ice lies at
sea level + 9 % of its
thickness, while the antarctic
ice sits several kilometers high in the sky, and the surrounding apron of the stuff is immune to windage because of the circumpolar continent in its midst.
This SMOS
thickness map reveals how thin the recently refrozen
sea ice on the Atlantic side still is:
