Turning a spotlight on grazing

Microscopic plankton in the surface ocean make planet Earth habitable by generating oxygen and forming the basis of marine food webs, yielding harvestable protein. For over 100 years, oceanographers have tried to ascertain the physical, chemical, and biological processes governing phytoplankton blooms. Zooplankton grazing of phytoplankton is the single largest loss process for primary production, […]

Modern OMZ copepod dynamics provide analog for future oceans

Global warming increases ocean deoxygenation and expands the oxygen minimum zone (OMZ), which has implications for major zooplankton groups like copepods. Reduced oxygen levels may impact individual copepod species abundance, vertical distribution, and life history strategy, which is likely to perturb intricate oceanic food webs and export processes. In a study recently published in Biogeosciences, […]

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 […]

Global Ocean DOM Data Collection Under Construction

Dennis Hansell and Craig Carlson are compiling DOM data (DOC/TDN) from the global ocean with the intention of making those available to current and future generations of ocean scientists. Please contribute your data. We are compiling the long line (U.S. GO-SHIP and earlier) DOC/TDN and affiliated hydrographic data into a single collection. Our intention is […]
