Introduction. The Arctic Ocean has undergone unprecedented changes in sea ice extent and thickness in recent decades, with old, stable multi-year ice (MYI) being largely replaced by young, thinner first-year ice satellite-based study of sea ice dynamics in the Central Canadian Arctic Archipelago book (Maslanik et al.,Stroeve et al., ).These changes, which have been particularly pronounced in the Beaufort and Chukchi seas (Meier et al.,Douglas, Cited by: 1.

Introduction. Climate-driven alterations of the environment are fastest and deepest in the Arctic Ocean (), where warming, acidification, the demise of sea ice and ensuing changes in freshwater balance and upper ocean dynamics impact the marine ecosystem in different concurrent ways ().At the lowest level of the food web, the photosynthetic primary production (PP) of organic matter (OM) by Cited by: The reduction in sea ice and warming of Arctic sea waters also has changed circum-arctic vegetation although the patterns are complex: a satellite-based measure of plant greening (NDVI) increased during –, suggesting an earlier green-up of the vegetation but then NDVI declined from – (Bhatt et al.

Recently, however, there has been significant arctic warming, accompanied by changes in the extent, thickness distribution, and properties of the arctic sea ice cover.

The need to understand these changes and their impact on arctic stratification and circulation, sea ice evolution, and the acoustic environment motivate this initiative.

5th Ave., Anchorage, AK,USA, [email protected] Alaska's National Parklands in the arctic have struggled. Forty years ago, climate scientists predicted the Arctic to be one of Earth’s most sensitive climate regions and thus extremely vulnerable to increased CO2.

The rapid and unprecedented changes observed in the Arctic confirm this prediction. Especially significant, observed sea ice loss is altering the exchange of mass, energy, and momentum between the Arctic Ocean and by: Temporal and spatial variations of air-sea CO2 fluxes in the Canadian Arctic Archipelago.

To study changes in sea ice characteristics indicative of ringed seal habitat (and linked, through predator/prey relationships, to polar bear habitat), we examined historical changes in sea ice concentration and type within M'Clintock Channel and the Gulf of Boothia, two regions of the Canadian Arctic Archipelago, during The Canadian High Arctic has been warming for several decades and is predicted to undergo substantially more warming over the next century.
