First-year sea ice extent was lowest during the glacial stadials suggesting complete coverage of the Arctic Ocean by multi-year sea ice. These findings demonstrate a clear relationship between temperature and first-year sea ice extent in the Arctic and suggest multi-year sea ice will continue to...
The field of Arctic sea ice prediction on “weather time scales” is still in its infancy with little existing understanding of the limits of predictability. This is especially true for sea ice deformation along so-called Linear Kinematic Features (LKFs) including leads that are relevant for marin...
Now, understand that “arctic sea ice” as a term for “an area of ocean covered by sea ice up north” includes more than the nominal 14.0 Mkm^2 area of the “arctic ocean” itself. Those who spend our billions tracking these thigns add the sea ice over Hudson Bay, the Labrador and...
Arctic sea ice retreat is linked to extrapolar thermal energy import, while the potential impact of pan-Arctic river heat discharge on sea-ice loss has been unresolved. We reconstructed the Holocene history of Arctic sea ice and Russian pan-Arctic river heat discharge, combining ice-rafted debris...
Across the analyzed CMIP6 models, the projected increase in ocean surface stress in the Beaufort Gyre region is not correlated with the decrease in sea ice extent (Fig.5d). However, this does not imply that the decline in sea ice does not contribute to the simulated increases in ocean surfa...
Analysis of the entire SSM/I time series shows that there are significant differences in trend between sea ice extent and area, using different algorithms. This indicates that long-term trends in surface and atmospheric properties, unrelated to sea ice concentration, influence the computed trends....
Ever since the End Zone-series I've been focussing a lot on PIPS ice displacement arrows and atmospheric patterns in general, but I mustn't forget about temperatures, both air and sea surface. Especially the latter could extend the melt season some more
Intercomparison of the algorithms gives the differences between sea ice extent estimates, while comparison with ship observations shows the difference between each algorithm results and field data and helps explain the reasons of such huge discrepancies in sea ice extent estimates. Comparisons of ...
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at thePolar Science Center: As usual, the minimum was reached during September, and as with other data sets (extent and area)...
The sea ice undergoes a seasonal cycle, spreading across the Arctic waters during winter and retreating in the warmth of summer. Historically, the ice — which provides important habitat for walrus and polar bears— reaches its minimum extent between the first week of September and around the end...
