Biogeochemistry of suspended particulate matter and sediment from the nearshore zone of Herschel Island, Canada
Collapse of permafrost coasts delivers large quantities of particulate organic carbon (POC) to arctic coastal areas. The objective of this study is to assess the pathways and fate of POC derived from thawing and eroding permafrost coasts in the nearshore zone, to better understand its impact on the...

Collapse of permafrost coasts delivers large quantities of particulate organic carbon (POC) to arctic coastal areas. The objective of this study is to assess the pathways and fate of POC derived from thawing and eroding permafrost coasts in the nearshore zone, to better understand its impact on the carbon cycle and climate. We collected suspended particulate matter and sediment samples at the coastline and in the nearshore zone of Herschel Island - Qikiqtaruk (N 69.60°; W 139.00°) during a two‐week period in July‐August 2017. Locations were labelled A - H clockwise around the island, starting at the NE corner (Collinson Head). Samples were taken in transects perpendicular to the coast, at point locations offshore ('Monitoring point 1 - 3'), and from 'thaw streams', creeks carrying material from retrogressive thaw slumps and other abrupt thaw features, at various locations around the island.
