ClearEarth Observations for Monitoring Marine Coastal Hazards and Their Drivers
Researchers reviewed the use of Earth observation technologies for monitoring coastal hazards including pollution, sea-level changes, and extreme weather events. The study highlights how satellite-based monitoring and forecasting systems are increasingly important for managing risks to densely populated coastal zones, including emerging threats from marine pollution such as microplastics.
Small Microplastics As a Main Contributor to Plastic Mass Balance in the North Atlantic Subtropical Gyre
Researchers re-analyzed microplastic data from the North Atlantic Subtropical Gyre and found that small microplastics (under 1 mm) constitute the dominant fraction of plastic mass in surface waters, contradicting previous estimates. The finding helps explain the apparent "missing plastic" problem and suggests that small fragments are a more significant pollution concern than previously recognized.
SKIM, a Candidate Satellite Mission Exploring Global Ocean Currents and Waves
Researchers described the Sea surface KInematics Multiscale monitoring (SKIM) satellite mission concept, designed to measure global ocean surface currents and waves including in the Arctic up to 82.5 degrees north, with applications including tracking of buoyant marine debris accumulation zones.
Anticyclonic eddies increase accumulation of microplastic in the North Atlantic subtropical gyre
Researchers found that anticyclonic eddies significantly increase the accumulation of microplastics in the North Atlantic subtropical gyre, using in situ measurements combined with satellite observations and modelling to reveal eddy-driven convergence as a key mechanism controlling microplastic distribution.
Assessing microplastics pollution in the atmosphere and riverine system in the Pyrenees
This study measured airborne microplastics deposited in the Pyrenees mountains — a remote area far from major urban sources — finding significant contamination in both air deposition and river sediments. The results confirm that microplastics are transported long distances by wind and deposited even in pristine mountain environments. Rivers then act as conduits that transport these atmospherically deposited microplastics toward the ocean.
