XI (2018-2023): Instrumentation for Multidisciplinary Monitoring of an Alaskan Peatland

• U.S.G.S. - Geology, Geophysics, Geochemistry Science Center (GGGSC), United States of America

This small seismic array was deployed in April 2018 at a permafrost site near Fairbanks, Alaska to continuously record ambient seismic noise for the purposes of near-surface monitoring and characterization. The array of 9 stations form a transect between a forested permafrost plateau down a gentle slope to two collapse-scar bogs. From April 2018 - June 2019, the array consisted of 4 broadband stations and 5 short period geophones. In June 2019 the broadband stations were replaced with the same short period geophones for continued operation going forward. The stations are co-located with other geophysical measurements, temperature, soil moisture, and carbon flux data to allow for a more complete understanding of how physical processes control biogeochemical processes, and how those relationships vary across the thaw gradient. This study takes place at the site of the Alaskan Peatland Experiment (APEX).
