Absolute gravity campaign within the BalMarGrav project (Latvia, Lithuania), August 1-3, 2023

Added on: 08 August 2023

A gravity campaign with the use of the A10-020 absolute gravimeter conducted by the team of the Institute of Geodesy and Cartography (Poland), with the support from colleagues from Lithuania and Latvia to provide reference gravity measurements for the marine gravimetric surveys within the project.

In total nearly 1700 km were travelled to conduct absolute gravity and vertical gravity gradient determinations on three locations near the ports of Klaipeda, Liepaja (Grobina) and Riga. Remaining relative gravity measurements will be conducted by colleagues from Lithuania and Latvia. Similar measurements are planned at the ports of Szczecin in the upcoming weeks to complete providing reference measurements.
