Irradiance-normalized non-photochemical quenching (NPQ): a new proxy of iron stress for phytoplankton
Ryan-Keogh and his colleagues used NPQ to fingerprint the photo-physiological response of phytoplankton to their environment.
The causes of the 90-ppm glacial atmospheric CO2 drawdown still strongly debated
Joint Science Highlight with US-Ocean Carbon & Biogeochemistry (US-OCB). Using an observationally constrained earth system model, S. Khatiwala and co-workers (2019, see reference below) compare different processes that could lead […]
Climate change induced spectacular increase of the land-ocean inputs in the Arctic Ocean
Measurements of radium-228 (228Ra) in the framework of the 2015 U.S. GEOTRACES Arctic Transect (GN01), revealed that the surface water content of this tracer has almost doubled over the last […]
