A two-part seabed geomorphology classification scheme; Part 2: Geomorphology classification framework and glossary (Version 1.0)

, 2023
Maps of seabed geomorphology derived from bathymetry data provide foundational information that is used to support the sustainable use of the marine environment across a range of activities that contribute to the Blue Economy. The global recognition of the value of the Blue Economy and several key global initiatives, notably the Seabed 2030 project to ...

Characteristics, classification and genetic mechanism of pockmarks

地质科技通报, 2023
Pockmarks are a kind of negative geomorphology formed by overpressure fluid spilling from the seabed. They are widely distributed in various underwater tectonic environments (such as continental margin basins and accretion wedges).

Seabed geomorphology of the Porcupine Bank, West of Ireland

Journal of Maps, 2015
ABSTRACTA new map of the seabed geomorphology on the Porcupine Bank, located at the western edge of the north-eastern Atlantic shelf west of Ireland, uses high-resolution multibeam bathymetric and backscatter data as well as numerous shallow seismic profiles to identify individual landforms.

Geomorphological significance of shelf-incised valleys as mesophotic habitats

Frontiers in Remote Sensing, 2023
Geomorphology provides the core attributes for outlining marine seascapes, once the structural complexity of the seafloor mediates several oceanographic processes and ecosystem services, and is positively associated with biodiversity.

Lifting back the waters: Marine geophysics provides new insights into the uThukela Banks Marine Protected Area

South African Journal of Science, 2022
Using the first high-resolution geophysical data set collected from the uThukela Banks Marine Protected Area (MPA), we reveal a plethora of hitherto unknown or poorly resolved seabed features.

A Characterisation of Benthic Currents from Seabed Bathymetry: An Object-Based Image Analysis of Cold-Water Coral Mounds

Remote Sensing, 2022
Seabed sedimentary bedforms (SSBs) are strong indicators of current flow (direction and velocity) and can be mapped in high resolution using multibeam echosounders.

Subsidence model of the ancient Alexandria Royal port linked to sea-level rise and natural hazards using integrated geophysical methods

Egyptian Journal of Aquatic Research, 2021
Marine geophysical methods are quite valuable in geoarchaeological investigations and remote seabed classifications due to their capability to cover vast areas in a short time and reveal fine details of the seafloor and subsurface features in unexcavated
