Field experiments

Upcoming

• Collaborative marine cruise, North Carolina, Cape Fear USA
  – We are conducting a 33-days cruise on board of the M/V Langseth, May-June 2023 along shore North Carolina, Cape Fear USA to study the Mass Transport Deposits and the hazard associated with. See internship offers for joining the cruise!

2020-2022 surveys

Multi-instrumental campaign in Bangladesh (2022)
– We have conducted an amphibious field campaign in Bangladesh In April 2022 where we have deployed GNSS, Relative Gravimeters and the Nano-Cyclopee instruments with the overall target to measure the Geoid and the Relative Sea Level in Southwest Bangladesh

GNSS campaign in 2020 in Bangladesh (2020)
– We have conducted a large campaign of re-occupation of Geodetic monuments in Southwest Bangladesh. We have deployed campaign GNSS/GPS to measure the elevation changes since 20-30 yrs.
