High resolution temperature profiles along a latitudinal gradient near Utqiagvik, Atqasuk, and Ivotuk Alaska from 2016-2019
The research project will assist in investigations of year-around CH4 (methane) and CO2 (carbon dioxide) fluxes at three Alaskan Arctic sites (Utqiagvik, Atqasuk, and Ivotuk) across a latitudinal gradient of about 300 kilometers from the northern part of the Arctic Coastal Plain to the foothills of...
