Known for	leading expert on permafrost

Steven Kokelj is a Canadian environmental scientist.^[1] Meagan Wohlberg, writing in the Northern Journal, called him the Northwest Territories' foremost expert on permafrost.^[2]^[3]

Kokelj's PhD thesis, published in 2003, was entitled, "Near-surface Ground Ice in Sediments of the Mackenzie Delta Region, Northwest Territories".^[4] Since then Kokelj has held several research positions in the Northwest Territories.

In 2014 Kokelj was the very first speaker invited to lead off a series of talks on Northern issues, hosted in NWT's legislative assembly.^[5] The talks were modelled after the TED conferences, and the legislature has made them available via podcast.

Many sumps from the 1970s have collapsed, or started to fail, releasing potassium chloride into the environment, says federal environmental scientist Steven Kokelj.
