Marine gravity data of the Southern Baltic Sea region

Description

Gravity data were registered in 2021 and 2023 by a research team from Gdańsk University of Technology during two gravimetric measurement campaigns in the southern Baltic Sea.  The campaigns were carried out aboard the Polish Navy research vessel ORP "Heweliusz" and the training ship s/s "Nawigator XXI." The routes were planned according to the needs of gravimetric measurements. In both cases, the MGS-6 Marine Gravity System by Micro-g LaCoste was used. The campaign on ORP "Heweliusz" began on June 6, 2021, at 19:59 in Gdynia Port and ended on June 10, 2021, at 10:53 in the same port. It lasted continuously for 86 hours and 54 minutes. The ship remained in constant motion, as reflected in the GNSS antenna positions and other measurement sensors.
The campaign on s/s "Nawigator XXI" began on June 5, 2023, at 20:00 in Szczecin Port and ended on June 15, 2023, at 11:30 in the same port. During the voyage, the ship docked in the ports of Rønne (entry on June 6, 2023, at 09:00; departure on June 9, 2023, at 20:00) and Klaipeda (entry on June 10, 2023, at 09:00; departure on June 14, 2023, at 18:00). At both ports, gravimetric points located on the docks were referenced, transferring gravity values from the geodetic control points in Denmark (Bornholm) and Lithuania (Klaipeda).
GNSS receivers, data was recorded from aboard the ship. These devices provided data to determine corrections for vertical accelerations caused by the ship's motion and the dynamic effect resulting from the cross-coupling of horizontal and vertical acceleration components.
The analyses of the data presented are presented in the article “Data Processing Strategies for Marine Gravity Using Gravity Anomalies and Gravity Disturbances: A Case Study in the Southern Baltic Sea Region.”
