Seagrass in Mosquito Lagoon recovered to pre-collapse levels
What the study found The study found that seagrass in Mosquito Lagoon, Florida, recovered rapidly after Hurricanes Ian and Nicole. It was still in significant decline until March 2023, then returned to pre-collapse levels in summer 2023 and later. Why the authors say this matters The authors say the findings raise awareness that Mosquito Lagoon…
HYBRID improved tidal and stratification simulation in the Yellow Sea
What the study found The hybrid z*-isopycnal vertical coordinate system (HYBRID) performed better than the z* coordinate system (ZSTAR) in simulations of Yellow Sea tides and stratification. It gave a more accurate picture of sea surface temperature, vertical thermal structure, and several tidal measures, especially in summer when the water column is strongly stratified. Why…
New BedMachine updates improve Antarctic and Greenland bed maps
What the study found The study reports major improvements in the description of the bed topography and bathymetry, meaning the shape of the land under the ice and the ocean floor, for both the Antarctic and Greenland Ice Sheets. Why the authors say this matters The authors say these improvements address known limitations in BedMachine,…
Bed topography uncertainty strongly affects Antarctic ice-sheet projections
What the study found Uncertainty in bed topography, the shape and elevation of the land beneath the Antarctic Ice Sheet, can substantially affect simulations of Antarctica's future evolution. The abstract reports that these errors can change the Antarctic contribution to sea level by more than 40 cm by 2150 and 1 m by 2300. Why…
Hydrology strongly controlled nitrate cycling in a tidal freshwater river
Study reveals how discharge and residence time control nitrogen cycling in tidal freshwater zones, with denitrification dominating during low-flow periods and implications for managing estuarine.
Baranof Island glaciers persisted into the Holocene and then retreated rapidly
Cosmogenic dating and sediment cores reveal glacial history of Baranof Island and document tenfold acceleration in glacier retreat since 1986, with implications for sea-level rise.
Sea ice reference data prepared for satellite altimetry comparison
A standardized collection of sea ice measurements from 1993–2024 enables validation of satellite altimetry thickness products across both polar regions at matching spatial and temporal scales.
Cala del Cefalo showed major shoreline retreat and dune degradation
Multi-technique assessment of coastal dune degradation at a protected Mediterranean site, documenting shoreline retreat, vegetation loss, and increased storm vulnerability under climate change.
Atlantic δ13CDIC reconstructed with machine learning
Gaussian Process Regression reconstructs stable carbon isotope composition of dissolved inorganic carbon in the Atlantic Ocean, expanding historical data coverage 7.65-fold.
Freshwater and carbon export to northern Alaska estuaries increased
Model-based analysis reveals intensified freshwater and organic carbon discharge to northern Alaska’s Beaufort Sea estuaries driven by permafrost thaw and hydrological cycle changes.
