  • Historical phases of ocean oxygen minimum are associated with near extinctions of mesopelagic fish, suggesting risks of future deoxygenation to marine fisheries due to warming, according to an analysis of a fish otolith record from a Mediterranean sediment core.

  • Ziveri et al find calcifying phytoplankton dominate pelagic CaCO3 production, but a large portion of this CaCO3 dissolves in the photic zone - they suggest the processes driving shallow CaCO3 dissolution are key to understanding the role of planktonic calcifiers in regulating atmospheric CO2.

  • Increasing atmospheric concentrations of anthropogenic carbon dioxide and acidification of surface waters have led to basin wide reductions in planktic foraminifera calcification in the Mediterranean Sea, suggest sediment core analyses of shell weight, geochemistry, and supporting proxies.
