Radium in Changing Environments: A Novel Tracer of Iron Fluxes at Ocean Margins
Phytoplankton are microscopic plants that live in the sunlit surface ocean. Iron (Fe) is an essential nutrient for phytoplankton, which use Fe for photosynthesis, converting carbon dioxide (CO2) to oxygen and organic matter. Organic carbon that sinks...

GEOTRACES: Physical and Chemical Forcing of Diazotrophy in the (sub) - tropical Atlantic Ocean
The oceans play a central role in the global carbon cycle, and have taken up ca. 30-40% of the anthropogenically produced CO2. It has long been known that ocean biota play a major role in sequestering CO2 on very long time scales (>1000 y). Recent...

Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS) - Lam - OES
The surface ocean is home to billions of microscopic plants called phytoplankton which produce organic matter in the surface ocean using sunlight and carbon dioxide. When they die they sink, taking this carbon into the deep ocean, where it is stored ...
