Objective(s): To test new equipment for characterizing the energy fluxes from and around thermokarst slumps; to establish a baseline for future subsidence measurements; and, to quantify lake and atmospheric methane concentrations in relation to thermokarst slumps.
Project Description: This licence has been issued for the scientific research application No.5023. The goals for this expedition are to test new equipment for characterizing the energy fluxes from and around thermokarst slumps and to establish a baseline for future subsidence measurements. Additionally, lake and atmospheric methane concentrations in relation to thermokarst slumps will be quantified. The research team will conduct ground-truth surveys using a differential GPS. Small GPS observation stations will be installed, approximately 2 meters above the surface, to collect GPS data for the analysis of reflected GPS signals. Analysis of these signals will allow us to observe any surface movement that might be due to ground subsidence. The research team will deploy one environmental monitoring station to measure air temperature and relative humidity, wind, net radiation, soil temperature and moisture, and soil heat flux. The team will ... Show more
