Air-sea gas disequilibrium drove deoxygenation of the deep ice-age ocean
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.

Dissolved neodymium isotopes and Rare Earth Elements combined with oxygen isotopes trace water masses in the Fram Strait
Georgi Laukert and co-workers (2017, see reference below) provide new insights into the sources, distribution and mixing of water masses passing the Fram Strait, the gateway between the Arctic Ocean […]
Oxygen biogeochemistry exerts a strong influence on cobalt cycling
This is an important result of the US GEOTRACES East Pacific Zonal Transect (EPZT) cruise (GP16) discussed by Hawco and his co-workers (2016, see reference below). The distribution of dissolved […]
Tracking the sea ice exported from the Siberian Shelf to the Arctic Ocean
An original method based on the use of the couple salinity – δ18O allows determining the fractions of water that had been removed as ice across the shelf and the […]
