Shipboard Marine Gravimeters Operated on Vessels in the U.S. Academic Research Fleet: Capabilities and Data Quality

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Shipboard gravity anomaly data provide high‐resolution information for a wide range of Earth and ocean science research as well as ground‐truthing US national geodetic modeling. Motivated by the end of life‐cycle for legacy Bell aerospace marine Gravity Meter system (BGM‐3) gravimeters onboard vessels in the U.S. Academic Research Fleet, a new

Enhanced Seafloor Topography Inversion Using an Attention Channel 1D Convolutional Network Based on Multiparameter Gravity Data: Case Study of the Mariana Trench

Journal of Marine Science and Engineering
Seafloor topography data are fundamental for marine resource development, oceanographic research, and maritime rights protection. However, approximately 75% of the ocean remains unsurveyed for bathymetry.

Swath sonar multibeam bathymetry during HEINCKE cruise HE450 with links to raw data files of bathymetry and water column information

, 2016
The aim of the cruise was to explore gas emissions using the echosounders of the ship along the slope of the Barents Sea up to Svalbard to find more evidence for dynamic changes of gas hydrates and emissions of free gas.

Understanding satellite-derived bathymetry using Sentinel 2 imagery and spatial prediction models

GIScience & Remote Sensing, 2020
Optical satellite data is an efficient and complementary method to hydrographic surveys for deriving bathymetry in shallow coastal waters. Empirical approaches (in particular, the models of Stumpf and Lyzenga) provide a practical methodology to derive ...

Mapping of Cold-Water Coral Carbonate Mounds Based on Geomorphometric Features: An Object-Based Approach

Geosciences, 2018
Cold-water coral reefs are rich, yet fragile ecosystems found in colder oceanic waters. Knowledge of their spatial distribution on continental shelves, slopes, seamounts and ridge systems is vital for marine spatial planning and conservation.
