SDUST2023BCO: a global seafloor model determined from a multi-layer perceptron neural network using multi-source differential marine geodetic data [PDF]

Earth System Science Data
Seafloor topography, as a fundamental marine spatial geographic information, plays a vital role in marine observation and science research. With the growing demand for high-precision bathymetric models, a multi-layer perceptron (MLP) neural network is ...

Bathymetric effects and corrections in marine CSEM data [PDF]

Geophysics, 2011
Abstract The effect of seafloor topographic variations on controlled-source electromagnetic (CSEM) responses is investigated using a finite-difference modeling approach for both petroleum and gas-hydrate exploration scenarios. In a deepwater reservoir model, distortions in the inline electric field responses are mainly due to galvanic

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

River Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Comparative Analysis of Wavelet-Based Anisotropy Index Calculation for Bathymetric Data

Sakarya University Journal of Computer and Information Sciences
This study investigates the relationship between seabed structures and ship manoeuvrability by applying an anisotropic transformation to bathymetric data. The one of the selected study areas is the downstream section of the Mississippi River in Chalmette,

Automated object detection based on YOLOv11 for monitoring benthic population dynamics: A new approach combining photogrammetry and open‐source GIS tools applied to sea cucumbers

Remote Sensing in Ecology and Conservation, EarlyView.
This research established a new object detection model based on YOLOv11 to recognise benthic organisms, specifically sea cucumbers, by utilising high‐resolution photogrammetric‐based orthomosaics acquired along infralittoral Mediterranean Sea beds. The model demonstrated impressive performance metrics and, when combined with the Deepness plugin for the
