How bubbles may speed up CO2 uptake by the ocean
Plymouth Marine Laboratory
Published: 6 January 2026
Analysis of 4,082 hours of sea-air CO2 flux measurements across 17 cruises found clear evidence of asymmetric bubble-mediated CO2 transfer, increasing global ocean CO2 uptake estimates by about 15%.

Can spores transported from distant terrestrial regions act as cloud seeds over the Arctic Ocean?

R/V Mirai observations reveal that land-emitted spores travel over 100 km to the Arctic Ocean and may seed cloud ice crystals, though mixing with sea-salt particles during transport reduces their effectiveness.
