Updated description of Freshwater Seepage Into Sediments of the Shelf, Shelf Edge, and Continental Slope of the Canadian Beaufort Sea from
The continental shelf of the Canadian Beaufort Sea caused by the transgression associated with the last deglaciation is researched to see if it's causing decomposition of relict offshore subsea permafrost and gas hydrates.
toThe continental shelf of the Canadian Beaufort Sea is investigated to see if it is causing decomposition of relict offshore subsea permafrost and gas hydrates.

Changed value of field
local_relevance
toThe continental shelf of the Canadian Beaufort Sea may be a major source of subsea permafrost and gas hydrate decomposition, which would impact our understanding of the extent of landscape carbon storage in the NWT, and its potential to be released into the atmosphere.
