Satellite Data Trace Seasonal Freshwater Dispersion in Hudson and James Bays

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Freshwater dispersal controls stratification, circulation, and biogeochemical processes in Hudson and James Bay (HJB); however, limited field observations hinder understanding of how different freshwater types drive change. This study uses Aqua‐Moderate Resolution Imaging Spectroradiometer and Soil Moisture and Ocean Salinity‐Microwave Imaging

Economic impacts on key Barents Sea fisheries arising from changes in the strength of the Atlantic thermohaline circulation [PDF]

A bioeconomic model of key fisheries of the Barents Sea is run with scenarios generated by an earth system model of intermediate complexity to assess how the Barents Sea fisheries of cod (Gadus morhua) and capelin (Mallotus villosus) are affected by ...

Strengthening of Labrador Sea Overturning Linked to Subsurface Freshening Over Recent Decades

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The Labrador Sea is a key formation site for dense waters that contribute to the lower limb of the Atlantic meridional overturning circulation (AMOC). Recent observations have revealed a distinctly weak overturning in this basin, attributed to compensating effects of temperature and salinity anomalies on density.

Method for Automatic Path Planning of Underwater Vehicles Considering Ambient Noise Fields

Journal of Marine Science and Engineering
To tackle the problem of existing underwater vehicle covert path planning methods ignoring ambient noise fields, an automated path planning method based on a statistically characterized environmental noise field is proposed.

Halogenated Organic Compounds: A Massive Halogen Reservoir and an Intriguing Component of the Marine Dissolved Organic Matter Pool

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Biogeochemical reactions produce volatile halocarbons and semi‐ to nonvolatile dissolved organic halogens (DOX) in marine systems. The former has a large influence on atmospheric chemistry, but little is known about DOX. Here, we present depth profiles of dissolved organic bromine (DOBr) and ‐iodine (DOI) isolated from the Central North ...

Developing an acceptance test for non-hydrographic airborne bathymetric lidar data application to NOAA charts in shallow waters [PDF]

, 2013
Hydrographic data of the National Oceanic and Atmospheric Administration are typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for nearshore areas.

An appraisal of backscatter removal and refraction calibration models for improving the performance of vision-based mapping and navigation in shallow underwater environments

Intelligent Systems with Applications
Vision-based mapping (VbM) is one of the fundamental origins of automation in remote and autonomous spatial data acquisitions. Complexity in obtaining accurate data arises when such a method is applied in the underwater environment.
