Deep Yedoma permafrost: A synthesis of depositional characteristics and carbon vulnerability [PDF]
, 2017 Permafrost is a distinct feature of the terrestrial Arctic and is vulnerable to climate warming. Permafrost degrades in different ways, including deepening of a seasonally unfrozen surface and localized but rapid development of deep thaw features ...

Thermokarst ponding, North Slave region, Northwest Territories
, 2017 This open file provides an inventory of thermokarst pond development between 1945 and 2005 in a study area that is representative of the southern North Slave region between Behchoko and Yellowknife, Northwest Territories. The primary purpose of this inventory is to approximate the location and size of thermokarst ponds in a study area representative of
