The Helgoland Gravimetric Observatory Germany (HELGOG) was established in March 2020 in the basement of the Biologische Anstalt Helgoland (BAH) of the Alfred Wegener Institute AWI, Helmholtz Centre for Polar and Marine Research. The main research focus is on the analysis of tidal and non-tidal ocean loading in the North Sea for the validation and calibration of the satellite mission GRACE Follow-On. This observatory includes the superconducting gravimeter iGrav 047. The superconducting gravimeter data are available for registered users from the IGETS data base hosted by GFZ. When using this dataset please cite it as follows

The HELGOG observations are integrated into the SFB1464: TerraQ at Leibniz Universität Hannover.
