Ground temperatures for Eastern Baffin Island, Canada (2018-2019)

Rapid warming of the Arctic is promoting an expansion of shrubs and consequently, a greener land surface. This greening of the Arctic land surface may cause many feedbacks, including a potential acceleration of carbon release through permafrost thaw. Permafrost thaw is triggered by warmer ground tem...

Description
Summary:Rapid warming of the Arctic is promoting an expansion of shrubs and consequently, a greener land surface. This greening of the Arctic land surface may cause many feedbacks, including a potential acceleration of carbon release through permafrost thaw. Permafrost thaw is triggered by warmer ground temperatures that can occur when expanding shrubs trap snow which acts as a blanket and insulates the ground surface from cold air. We collected this dataset of 10 centimeter (cm) ground temperatures at 22 study locations throughout eastern Baffin Island, Canada to better understand the relationship between a greener Arctic land surface and warming ground temperatures. Temperatures were collected from approximately 2018-07-21 to 2019-08-21 at hourly or every four-hour intervals with Thermochron iButtons (DS1925L or DS1922L, Maxim Integrated Products, accuracy ±0.0625°Celsius (C) or ±0.5°C, respectively, from −40°C to +85°C).
