Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 41, Issue 5, Page 686-701, July 2026.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Measuring Centimeter-Scale Sand Ripples Using Multibeam Echosounder Backscatter Data from the Brown Bank Area of the Dutch Continental Shelf

Geosciences, 2020
Backscatter data from multibeam echosounders are commonly used to classify seafloor sediment composition. Previously, it was found that the survey azimuth affects backscatter when small organized seafloor structures, such as sand ripples, are present ...

Post‐Miocene Transtensional Opening of the Northern Red Sea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The mechanism of opening, as well as the crustal characteristics of the northern Red Sea are subject of ongoing controversial scientific debate. With the objective of elucidating the nature of rifting in this area, a grid of 2D multi‐channel reflection seismic data was acquired off the Al Wajh carbonate platform (AWCP), and supplemented by ...

M72-5 raw data of EM120 multibeam echosounder (bathymetry, beam time series & water column)

, 2018
Multibeam echosounder (MBES) data recorded during RV METEOR cruise M72-5 between 14.05.2007 and 06.06.2007 in the Black Sea. This cruise focused on the biogeochemical and microbiological processes around the oxic/anoxic interface of the chemocline in the

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...

Hotspot magmatism and volcanic hazard at Cape Verde through the lens of shipborne surveying and dredging

Geology Today, Volume 42, Issue 4, Page 174-182, July/August 2026.
The Cape Verde archipelago is a long‐lived volcanic ocean island chain formed by a mantle plume in the Atlantic Ocean. The archipelago is characterized by ten subaerial islands with complex age relationships, abundant submarine volcanism and variable volcanic hazards.

Using seafloor echo-integrated backscatter for monitoring single beam echosounder calibration

Frontiers in Remote Sensing
IntroductionIn recent years, methods have been developed to calibrate seafloor backscatter measurements from hydrographic multibeam echosounders. Some of these methods involve the use of well-characterized reference areas that consistently exhibit stable
