ANTERMON | ANTarctic Electrical Resistivity Monitoring Network
ANTERMON aims to establish an observation network in Antarctica based on the soil electrical resistivity monitoring using geophysical techniques to improve the spatio-temporal understanding of active layer and permafrost dynamics and water availability with minimal environmental disturbance. It allows detecting high-temporal resolution changes on freezing and thawing in larger spatial scale, providing new insight into the site-specific reactions of active layer and permafrost to climate change. A-ERT systems are installed in the GTN-P and CALM sites, where air, surface and borehole temperatures as well as snow thickness are being monitored. A-ERT systems are monitoring electrical resistivity in 6h interval at the same times in all sites. The data gathered from the network will allow for improved assessment of climate change impacts on permafrost dynamics and especially for its analysis with unprecedented temporal resolution. An example is the detection of short-lived events that promote fast active-layer and permafrost warming, potentially leading to abrupt permafrost thaw, such as heat advection associated with increasing atmospheric river events.
