Techniques for Classifying Seabed Morphology and Composition on a Subtropical-Temperate Continental Shelf

Geosciences (Switzerland), 2019
In 2017, the New South Wales (NSW) Office of Environment and Heritage (OEH) initiated a state-wide mapping program, SeaBed NSW, which systematically acquires high-resolution (2–5 m cell size) multibeam echosounder (MBES) and marine LiDAR data along

Changes in the geomorphology and littoral environment associated to dredged of seabed in Moa, Cuba

Minería y Geología, 2017
Geomorphological and environmental modifications that originate the dredging of carbonated mud in Cayo Moa bay were analyzed. Bathymetric data of different dates (1972, 2001 and 2010) were compared to evaluate the geomorphological changes in the bottom ...

Seabed geomorphology, substrate and benthic habitats informing long-term conservation of the Ascension Island Marine Protected Area

Journal of Maps
The Ascension Island Marine Protected Area (AI-MPA) is one of the largest areas of protected ocean, safeguarding a unique ecosystem in the South Atlantic Ocean. This study presents the first seabed geomorphology, substrate and benthic habitat maps of the

Tracking Sea Level Changes and Their Effect on The Seabed Geomorphology and Sediment Depositional System in Menai Strait by Using SBES and MBES Data

Al-Mukhtar journal of basic sciences
The Menai Strait, a tidal channel in northern Wales, represents a unique and dynamic marine environment where strong tidal currents drive significant changes in seabed geomorphology and sediment distribution. This study aims to investigate these changes using a combination of Single Beam Echo Sounder (SBES) data collected over seven years (2007–2014 ...

A geomorphological seabed classification for the Weddell Sea, Antarctica [PDF]

Marine Geophysical Research, 2015
Sea floor morphology plays an important role in many scientific disciplines such as ecology, hydrology and sedimentology since geomorphic features can act as physical controls for e.g. species distribution, oceanographically flow-path estimations or sedimentation processes.

Seabed Sediment Classification Using Spatial Statistical Characteristics

Journal of Marine Science and Engineering, 2022
Conventional sediment classification methods based on Multibeam Echo System (MBES) data have low accuracy since the correlation between features and sediment has not been fully considered.

The value of multibeam bathymetry in marine spatial planning in South Africa: A review

South African Journal of Science, 2023
Given a growing global population and shift to embrace the blue economy, a need for marine spatial planning (MSP) has emerged in South Africa to sustainably resolve the rising conflicts over the use of marine and seabed resources and services.

LATE QUATERNARY SEABED GEOMORPHOLOGY OF THE PROKLJAN LAKE (KRKA RIVER ESTUARY)

, 2021
A multiproxy investigation has been carried out to study the seabed geomorphology of the Krka River estuary located in the central Dalmatia. A detailed multibeam survey (MBES bathymetry and MBES backscatter), side scan sonar imaging, subbottom acoustics coupled with piston sediment cores and bottom samples were used to characterize 6.2 km2 of submerged
