Assessing the contribution of super-resolution in satellite derived bathymetry in the Antarctic
Estuarine, Coastal and Shelf ScienceThe difficulty of defining the depth of near-shore seas (bathymetry) arises from the limits imposed by traditional ship-based approaches during data collection. Although LiDAR sensors with green lasers have been used to solve some of these problems, they come at a high cost in terms of their footprint and are prone to inaccuracies in turbid water.

Integrating multibeam echo sounder and satellite-derived bathymetry for mapping of shallow coastal water [PDF]
Echosounders are the most used depth acquisition equipments in bathymetry surveys. Despite its widespread usage, the vessels that are equipped with echosounders and their necessary components are not able to enter certain areas where the water depth is ...

Thermal Stress Is Associated With Fragmentation of Mediterranean Posidonia oceanica Meadows
Global Change Biology Communications, Volume 1, Issue 3, September 2026.By combining a physiological model of cumulative thermal stress with AI‐based seagrass mapping, we show that chronic sublethal warming is associated with fragmentation of Mediterranean Posidonia oceanica meadows and increased regression risk by 2100. ABSTRACT Posidonia oceanica meadows, which underpin Mediterranean coastal ecosystems, are undergoing ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Ocean models can represent surface circulation at kilometer scales, but their computational cost limits broad experimentation. We present DeepCUN, a deep convolutional encoder–decoder (U‐Net) that emulates daily mean Baltic Sea surface current components on a 1‐nautical‐mile grid.

Satellite derived bathymetry for times of absent in situ data
, 2020 Knowledge of seafloor topography (bathymetry) is increasingly important as coastal environments are unprecedentedly stressed by climate change and anthropogenic pressure.

Assessment of Satellite Derived Bathymetry from Spot 7 satellite imagery / Hanim Fazira Abd Hamid [PDF]
, 2020 Bathymetry is the measurement of water depth in oceans, rivers, or lakes. Nowadays, the measurement of water depth also can be estimated by using remotely sensed satellite imagery which is known as Satellite Derived Bathymetry (SDB). Water depth from SDB

Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches
Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.
