Limitations of Boulder Detection in Shallow Water Habitats Using High-Resolution Sidescan Sonar Images

Geosciences, 2019
Stones and boulders in shallow waters (0−10 m water depth) form complex geo-habitats, serving as a hardground for many benthic species, and are important contributors to coastal biodiversity and high benthic production.

Global automated extraction of bathymetric photons from ICESat-2 data based on a PointNet++ model

International Journal of Applied Earth Observations and Geoinformation, 2023
We developed and tested a fully automated method to extract bathymetric photons globally from ICESat-2 ATLAS data by leveraging the PointNet++ model, which performs well for classification and segmentation of point clouds.

Analysis-ready optical underwater images of Manganese-nodule covered seafloor of the Clarion-Clipperton Zone

Scientific Data, 2023
We provide a sequence of analysis-ready optical underwater images from the Clarion-Clipperton Zone (CCZ) of the Pacific Ocean. The images were originally recorded using a towed camera sledge that photographed a seabed covered with polymetallic manganese ...

Circular structures on the seabed: differentiating between natural and anthropogenic origins—Examples from the Southwestern Baltic Sea

Frontiers in Earth Science, 2023
Hydroacoustic observations of shallow marine environments reveal a variety of seafloor structures–both of natural and anthropogenic origin. Natural processes can result in features with circular geometries on the seafloor, such as kettles, sinkholes or ...
