First wide-angle view of channelized turbidity currents links migrating cyclic steps to flow characteristics [PDF]

, 2016
Field observations of turbidity currents remain scarce, and thus there is continued debate about their internal structure and how they modify underlying bedforms.

Seafloor Sediments, Morphologic Features, and Geotechnical Properties of Harrison Bay in the Alaskan Beaufort Sea

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Sediments on Arctic continental shelves are impacted by sea ice and ice‐related processes for up to 9 months per year. As a result, seabed morphology in cold regions can exhibit features such as ice scours which are absent on lower‐latitude shelves.

Multibeam Bathymetry and CTD-Measurements in two fjord systems in Southeast Greenland [PDF]

Earth System Science Data, 2017
Abstract. We present bathymetry and hydrological observations collected in the summer of 2014 from two fjord systems in Southeast Greenland, using SS Activ with a multibeam system temporally installed over the side of the ship. Our results provide a detailed bathymetric map of the fjord complex around Skjoldungen Island and the outer part of ...

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
