Elastic Flexure of Young, Overlapping Basaltic Lava Flows Offshore the Galápagos and Hawaiian Islands: Observations, Modeling, and Thermal/Chronological Analysis

Geochemistry, Geophysics, Geosystems, 2020
A recent multibeam bathymetry survey in the Galápagos archipelago revealed a novel observation between the islands of Santa Cruz and Santiago: a steep flexural moat formed between two volcanic flows, nearly 50 m deep and about 500 m wide.

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

SS: Multibeam Backscatter: Utilization of Multibeam Bathymetry and Backscatter For Documenting and Planning Detailed Investigations of Deepwater Archaeological Sites

, 2010
In the past, planning detailed visual investigations of deepwater archaeological sites has primarily been done with side scan sonar and subbottom profiler data.

Bathymetry mapping with empirical bathymetry method based on sentinel application platform case study: Bawean Island, Central Java [PDF]

BIO Web of Conferences
Bathymetry information is an important requirement for the marine and fisheries sector in Indonesia. However, the acquisition of information is done in the traditional way, namely surveys using single/multibeam echosounder devices carried by ships.

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East

Decadal‐Scale Bathymetric Change in a Shallow Coastal Bay

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Coastal marshes and bays must accumulate sediment to maintain their position relative to mean sea level during periods of sea level rise (SLR). Resuspension of bay‐bottom sediment, which together with tidal inundation promotes marsh deposition, is sensitive to water depth, but quantitative measurements of bathymetric change across shallow bays

First Direct Observations of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behavior, and long‐term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations.

Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]

, 2005
The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

Bathymetry prediction from gravity data using combined linear regression and neural networks for enhanced cross-regional transferability

Geo-spatial Information Science
Linear regression (LR) and neural network methods are widely used to infer seafloor topography from satellite altimetry-derived gravity fields. LR methods are effective in capturing large-scale topographic features but often fail to resolve fine-scale ...
