Their research examines the effects of more
mobile ice cover since 2000.
An arctic ice pack that consists mostly of first - and second - year rather than multi-year sea ice, implies a thinner, more
mobile ice cover relative to conditions five or more years ago.
The absence of anomalous features evident in 2007 in SLP and stratospheric and surface winds in spring in 2011 indicates that accelerated decline associated with the former will not be an artifact of dynamical phenomena, although a thinner and more
mobile ice cover may lower the wind forcing threshold required for increased ice export.
The volume of ice divergence has doubled since 2000 due to a more
mobile ice cover as multiyear ice has declined, which can explain the drastic ice reduction in the Arctic Ocean in recent years.

Now the team is packing up their tools and
mobile labs so that they can be shipped out to the
ice sheet for the real deal: Boring through a half - mile of
ice covering Lake Whillans.
Skoda also claims the five - seat Rapid family car offers class - leading rear headroom (972 mm) and rear kneeroom (65 mm), as well as 19 «Simply Clever» features including four large door compartments, front seat pockets, an
ice scraper in the fuel filler flap, a double - sided boot floor
cover, two side boot compartments, a
mobile phone holder and slots to secure the rear seatbelt buckles.
He notes that the sat photos show that cloud
cover remains low and that the
ice is very
mobile at a time when the pack should be most firm (not really a surprise since ocean temps are much more important than air temps, and apparently it's the ocean temps that have been the largest factor in the recent sharp sea
ice reduction).
Overall, the curve shown in Figure 4 is commensurate with the notion that a thinner arctic
ice cover that is more
mobile can lead to greater seasonal and interannual variability, with a potential loss in predictability.
Sampling areas were split according to their
ice cover: North - West (less sea
ice cover), South - East (larger amplitude in sea
ice extent) and North - East / South - West (NESW) as bears from that zone are more
mobile among all regions of Svalbard.
A combined lack of coherence in
ice drift fields and reduced
ice concentrations in April 2011 relative to April 2007 suggest that springtime
ice dynamical contributions to fall sea
ice extent may be associated with sea
ice deformation and ridging within an increasingly
mobile and fractured
ice cover.
