OceansTwo Sentinel-2 satellites flown in tandem image ocean surface currents at 1 km resolution
Two optical satellites flying 27 s apart can track short wind waves and so map surface currents at 1 km scale, showing fine-scale divergence that altimetry misses.

OceansNew global ocean mean dynamic topography improves the Arctic but only slightly elsewhere
CNES-CLS22 is a modest update to the previous global mean sea surface height map, with clear gains in the Arctic and Nordic Seas but little change globally and persistent problems on continental shelves.

OceansOpen Sentinel-1 dataset labels oil slicks and look-alikes in the Eastern Mediterranean
The authors released a labeled set of radar image patches with 3225 oil objects and many look-alike scenes, so oil spill detectors can be tested on a common benchmark.

OceansSea level rebuilt at 945 tide gauges since 1900 shows a rise of 1.75 mm per year
The authors filled the gaps in 945 tide gauge records from 1900 to 2022 with a physics-based method, and the result matches other global sea level curves while following the raw records where they exist.
