International expedition to Tiksi, Yakutia
April 21, 2017
In the spring of 2017 an international multi-month project «Bykovsky Spring 2017: Subaquatic permafrost thaw - biogeochemical, microbiological and geophysical gradients and its implications for climate change» was launched that is сoordinated by The Alfred Wegener Institute for Polar and Marine Research (Potsdam, Germany). Scientific tasks of the project are microbiological, sedimentological, geochemical, climatological, hydrological, geocryological and geophysical studies.
We took our part in the expedition to Bykovsky Peninsula in April 2017 to carry out georadar surveys of the lakes of different salinity in order to obtain UWB georadar data and to compare our results with data obtained by other methods, including geological columns.
In total 14 gpr profiles were made with a different modification of the GROT 12 georadars using antennas 10m, 2m and 0.5m, receivers of different dynamic range and transmitters of 9 kV and 15 kV.
We thank the project coordinators and participants of the expedition for the opportunity and look forward to the fruitful results of the joint work.
