Evolution of marine gravel dunes on the open shelf under multi-directional currents conditions

open access: yesFrontiers in Earth Science, 2022
On inner continental shelves, a variety of coarse grained bedforms, such as gravel dunes, are shaped by hydrodynamic and morphodynamic processes. The formation and evolution of bedforms reflect a balance between seabed and coastal morphology, sediment ...

Blending single beam RoxAnn and multi-beam swathe QTC hydro-acoustic discrimination techniques for the Stonehaven area, Scotland, UK [PDF]

open access: yes, 2011
Surface properties of the seabed in a 180 km2 area of coastal waters (14-57 m depth) off northeast Scotland were mapped by hydro-acoustic discrimination using single and multi-beam echosounders linked to signal processing systems (RoxAnn for the single ...

A synthetic map of the north-west European Shelf sedimentary environment for applications in marine science [PDF]

open access: yesEarth System Science Data, 2018
Seabed sediment mapping is important for a wide range of marine policy, planning and scientific issues, and there has been considerable national and international investment around the world in the collation and synthesis of sediment datasets. However,

Review : Bathymetry Mapping Using Underwater Acoustic Technology

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019
The bathymetry mapping using underwater acoustic technology very important in Indonesia waters. Bathymetry is the result of measuring the height of the seabed so that the bathymetric map provides information about the seabed, where this information can ...

Synthetic shelf sediment maps for the Greenland Sea and Barents Sea

open access: yesGeoscience Data Journal, 2023
Seabed sediment maps underpin a variety of marine research endeavours. Seabed mapping data are available for many regions, but these usually provide discrete classifications which obscure underlying continuous properties of the sediments. Other areas are

Classification of seabed landforms on continental and island shelves

open access: yesFrontiers in Marine Science, 2023
The increasing availability and quality of high-resolution bathymetry data has led to a growing need for automated classification approaches to extract seabed features and better understand our ever-changing and complex seascapes.

Unsupervised Optical Classification of the Seabed Color in Shallow Oligotrophic Waters from Sentinel-2 Images: A Case Study in the Voh-Koné-Pouembout Lagoon (New Caledonia)

open access: yesRemote Sensing, 2022
Monitoring chlorophyll-a concentration or turbidity is crucial for understanding and managing oligo- to mesotrophic coastal waters quality. However, mapping bio-optical components from space in such shallow settings remains challenging because of the ...

Seabed Mapping for the 21st Century – The Marine Environmental Mapping Programme (MAREMAP): Preface [PDF]

open access: yesEarth and Environmental Science Transactions of the Royal Society of Edinburgh, 2014
During the 1970s and 1980s, the British Geological Survey (BGS) carried out systematic surveys of the seabed and subseabed around Britain, as part of a Government-funded programme to map the UK Continental Shelf (UKCS). Using an array of sampling, coring and seismic profiling equipment, the programme resulted in a series of geological maps and ...
