Calcifying plankton: From biomineralization to global change The cycling of calcium carbonate (CaCO3) in the ocean is closely linked to seawater alkalinity and the regulation of atmospheric CO2. In the modern pelagic ocean, almost all CaCO3 is produced by three...

New in @science.org: Calcifying plankton #coccolithophores, #foraminifera & #pteropods quietly drive the ocean carbon pump. Their traits (incl. “shallow dissolution”) are missing from many climate models. Time to put CaCO₃ back in the picture. #ClimateScience 🌊 doi.org/10.1126/scie... #protistsonsky

Mating #pteropods get broken up by my video lights. Sorry!!!

This is really really cool 😎
Check out these beautiful #pteropods They look very much like #diacavolinia
#gastropoda
#molluscsofsrilanka

After a few rough days, some calm, open sea on #M197, perfect for collecting some #mud (and lots of #pteropods) from the deepest (>3000m) parts of the #Mediterranean Sea.
