sea ice productionIn Arctic coastal polynyas, persistent areas of thin ice, a large amount of new ice forms during winters. Significant heat is lost through these regions of thin ice. Knowing how much ice is produced in polynyas is important for determining overall cold saline water formation ...
Figure 1. Map of the Arctic Ocean showing the average minimum and maximum sea ice extent, as well as the major bathymetric features, and other significant geographic locations. Over the last half-century Arctic acoustics research and development has largely supported submarine operations. The importan...
In 2019, the Swedish icebreakerOdenset out on theRyder 2019Expedition to map and retrieve marine sediment cores from the uncharted Sherard Osborn Fjord and southeastern Lincoln Sea (Fig.1). Here we examine Holocene sea-ice dynamics based on two gravity cores (Ryder19-12-GC1, Ryder19-14-GC1;...
Map of the Arctic region 2. Name: The Arctic Ocean derives its name from the Greek word 'arktos' which means 'bear'. 3. Size: How big is the Arctic Ocean?The Arctic Ocean is thesmallest oceanon earth and covers less than 3% of the earth’s surface. Much of the ocean is covered b...
(Fig.4c), freshwater input to the Arctic was reduced due to the closure of the Bering Strait, which today accounts for around 30% of total freshwater inflows to the Arctic Ocean10, alongside lower precipitation in the Arctic region under a colder regional climate and ice-damming of major ...
Shifting El Nio inhibits summer Arctic warming and Arctic sea-ice melting over the Canada Basin Arctic climate changes include not only changes in trends and mean states but also strong interannual variations in various fields. Although it is known that tropical-extratropical teleconnection is ...
Theextent of sea ice, an important habitat for many animals, has declined in ways that make today’s mostly thin and seasonal sea ice landscape unrecognizable compared with the thicker and more extensive sea ice of decades past. With a shorter sea i...
Here we produce Arctic sea ice biomarker proxy records for the penultimate glacial (Marine Isotope Stage 6) and the subsequent last interglacial (Marine Isotope Stage 5e). The latter is a time interval when the high latitudes were significantly warmer than today. We document that even under such...

(b) shows the discrimination of sea ice cover (yellow) and open water (purple) based on the EW data, and (c) is the sea surface wind map of the case, where the gray tone represents the sea ice cover from the IMS data (note its discrepancy with the result in (b)). The color ...
