CEN project

On the left side, the location of Bylot Island in the Canadian Arctic Archipelago (top), and an aerial view of the study site showing the location of the six ponds considered in this incubation experiment. On the right side, photos are showing the three limnological categories of ponds that differed in erosion, transparency and terrestrial inputs. Map and photos credits to Vilmantas Preskienis.

The study site is located on Bylot Island, in the Canadian Arctic Archipelago (Nunavut). The ice wedge polygons are found in the Qarlikturvik valley, on the south bank of the river draining melt water from the C-79 and C-93 glaciers, near the CEN station.

The ponds are located on a 3–5 m thick terrace resulting from the aggradation of Holocene deposits composed of peat mixed with aeolian sands and silts (syngenetic permafrost).
