A new application of aerosol iron isotopes: tracing anthropogenic iron; an example of the North Atlantic Ocean

Conway and co-authors (2019, see reference below) present the first evidence that anthropogenic iron (Fe) from combustion sources is visible at the basin scale, using iron isotopic composition (δ56Fe) analysis […]

Upwelled hydrothermal iron stimulates massive phytoplankton blooms in the Southern Ocean

Joint Science Highlight with US-Ocean Carbon & Biogeochemistry (US-OCB). In a recent study, Ardyna et al (2019, see reference below) combined observations of profiling floats with historical trace element data and […]

Glacial erosion processes suspected to enhance the lability of particulate iron, with a strong influence on the biological demand in the subantarctic waters

As part of the GEOTRACES process study HEOBI (GIpr05) van der Merwe and co-workers (2019, see reference below) conducted a thorough characterization of the labile and refractory iron phases of the […]

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 […]

South Pacific particulate organic carbon fate challenges Martin’s Law

Joint Science Highlight with US-Ocean Carbon & Biogeochemistry (OCB). Carbon storage in the ocean is sensitive to the depths at which particulate organic carbon (POC) is respired back to CO2 […]
