Sea ice loss and the changing Arctic carbon cycle

Loss of Arctic Ocean ice cover is altering the carbon cycle in ways that are not well understood. Effectively “popping the top off” the Arctic Ocean, ice loss exposes the sea surface to warming and exchange of CO2 with the atmosphere. These processes are expected to increase CO2 levels in the Arctic Ocean, changing its […]

Estuarine sediment resuspension drives non-local impacts on biogeochemistry

Sediment processes, including resuspension and transport, affect water quality in estuaries by altering light attenuation, primary productivity, and organic matter remineralization, which then influence oxygen and nitrogen dynamics. In a recent paper published in Estuaries and Coasts, the authors quantified the degree to which sediment resuspension and transport affected estuarine biogeochemistry by implementing a coupled […]

A quest for change

“The only way we can change the geoscience culture is by a massive shift in individual mindsets, with the aim of moving the field from passively non-racist to actively anti-racist.” – Kuheli Dutt (2019) – Nature Geoscience “Racism, injustice and police brutality are awful on their own, but are additionally pernicious because of the brain power […]
