Bathymetry and sediment geochemistry of Lake Hazen (Quttinirpaaq National Park, Ellesmere Island, Nunavut) / G. Köck, and 6 others.
Title: | Bathymetry and sediment geochemistry of Lake Hazen (Quttinirpaaq National Park, Ellesmere Island, Nunavut) / G. Köck, and 6 others. |
Author(s): | Köck, G. |
Date: | 2012. |
In: | Arctic. (2012.), Vol. 65(1) (2012) |
Abstract: | Reports first detailed bathymetric study of Lake Hazen (Ellesmere Island, Nunavut), world's largest lake north of 74°. Data were used to determine optimal locations for sediment coring and for collection and analysis of profundal sediment cores. Geochemical profiles suggest that Lake Hazen is responding very slowly to climate change, as evidenced by increasing total organic carbon and lithogenic elements, as well as by changing sedimentation rates. |
