A Crossover Adjustment Method Considering the Beam Incident Angle for a Multibeam Bathymetric Survey Based on USV Swarms

Journal of Marine Science and Engineering
Multibeam echosounder systems (MBESs) are widely used in unmanned surface vehicle swarms (USVs) to perform various marine bathymetry surveys because of their excellent performance. To address the challenges of systematic error superposition and edge beam

Global Assessment of SWOT River Discharge Representation at Channel Bifurcations

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract SWOT river discharge products rely on the SWOT River Database (SWORD), designed mainly for single‐thread channels. We assess how well SWORD represents ∼65,000 river bifurcations from the Global River Topology (GRIT) network. SWORD geographically intersects both downstream branches at 88.2% of bifurcations, but only 2.0% of these have distinct ...

A Novel Cooperative Localization Algorithm Based on LSTM and Factor Graph for AUV Swarms

Journal of Marine Science and Engineering
To address localization error accumulation in autonomous underwater vehicle (AUV) swarms due to underwater acoustic communication interruptions, this paper proposes a cooperative localization method that integrates Long Short-Term Memory (LSTM ...

Investigating the role of air-sea forcing on the variability of hydrography, circulation, and mixed layer depth in the Arabian Sea and Bay of Bengal

, 2017
Summary An effort is made to understand and quantify the influence of near surface zonal and meridional winds, incoming shortwave radiation, and freshwater flux air-sea forcings on the seasonal variability of the hydrography, circulation, and mixed layer

Quantifying Land–Sea Connectivity Through Remotely Sensed River Plumes

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Coastal ecosystems are highly influenced by riverine freshwater inputs, but the nature of these influences is dynamic and hard to characterize. Here we present a method that leverages remote sensing data of river plumes to quantify land–sea connectivity.

A High-Precision Method for Evaluating the Similarity of Maritime Vessel Trajectories

Journal of Marine Science and Engineering
This study investigates the demand for high-precision trajectory similarity assessment in intelligent maritime navigation. This is done by analyzing discrepancies between GPS-derived trajectories and actual vessel paths, while identifying critical ...

SWOT‐Fitted River Bathymetry for Global Hydrodynamic Models

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present a robust, global method to reconcile absolute water surface elevations (WSE) from the Surface Water and Ocean Topography (SWOT) mission with a large‐scale hydrodynamic model by iteratively correcting river bathymetry. After removing sensor and representativeness bias, we update riverbed elevations under DEM and min‐depth feasibility

Method for Delineating the Formula Limit of the Continental Shelf under the Maximum Area Principle Constraint

Journal of Marine Science and Engineering
In current practices of determining continental shelf area, the measured sediment thickness data do not effectively reflect the distribution of sediments across the area due to its dispersed nature.
