On the Variability of the Agulhas Bank Circulation

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract This modeling study investigates the variability of the Agulhas Bank (AB) circulation, focusing on its connections to the local wind forcing and the Agulhas Current (AC) as well as to teleconnections to the tropical South Atlantic. The mean AB circulation is dominated by a westward flow composed of a coastal jet, an outer‐shelf flow influenced

Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

A new benchmark for spatiotemporal fusion of Sentinel-2 and Sentinel-3 OLCI images

Earth Science Informatics
Abstract In Earth Observation, the use of multiple sensors has gained considerable attention as a tool to overcome the limitations inherent in individual data. Despite this, the operational lifespans of sensors are finite, creating an ongoing need to explore and integrate new sensors to sustain critical Earth Observation capabilities across ...

Fusing Multi‐ and Hyperspectral Satellite Data for Harmful Algal Bloom Monitoring With Self‐Supervised and Hierarchical Deep Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a self‐supervised machine learning framework for detecting and mapping the severity and speciation of harmful algal blooms (HABs) using multi‐sensor satellite data. By fusing reflectance data from operational polar‐orbiting satellite‐based instruments (VIIRS, MODIS, OLCI, and OCI) with TROPOMI solar‐induced fluorescence (SIF), our ...

Recent Changes and Variability of Suspended Particulate Matter in European and Mediterranean Coastal Waters Inferred From OLCI Data

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Suspended Particulate Matter (SPM) plays a central role in coastal marine ecosystems, influencing light availability, primary production, and transport of sediments, nutrients, and pollutants. Monitoring its variability is essential for understanding the impacts of both natural and anthropogenic pressures on coastal regions.
