Geomorphology of the Cook Islands, tropical South Pacific Ocean

Journal of Maps, 2023
We use the 2021 GEBCO grid to interpret the seabed geomorphology within the Cook Islands and adjacent areas. A complex geological history dating back to 125 Ma is manifested in a range of geoforms.

An Enhanced Photogrammetric Approach for the Underwater Surveying of the Posidonia Meadow Structure in the Spiaggia Nera Area of Maratea [PDF]

Journal of Imaging, 2023
The Posidonia oceanica meadows represent a fundamental biological indicator for the assessment of the marine ecosystem’s state of health. They also play an essential role in the conservation of coastal morphology.

Inversion of Side Scan Sonar Motion and Posture in Seabed Geomorphology

Polish Maritime Research, 2017
Side scan sonar measurement platform, affected by underwater environment and its own motion precision, inevitably has posture and motion disturbance, which greatly affects accuracy of geomorphic image formation.

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

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.
