Rapid melting of Antarctic sea ice largely driven by ocean warming
University of Gothenburg
Published: 18 March 2026
A study using 110,000 ocean profiles reveals that thinning of a cold subsurface layer and strong Southern Ocean storms in 2015 allowed warm deep water to reach the surface, triggering rapid Antarctic sea ice loss.

Tremendous amount of plastic floats as nanoparticles in the ocean
Royal Netherlands Institute for Sea Research (NIOZ)
Published: 9 July 2025
NIOZ researchers estimated 27 million tons of nanoplastics in the North Atlantic — more than all known micro- and macroplastics in all oceans combined, solving the missing plastic paradox.
