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 […]

Welcome to the first Korean participation in GEOTRACES

Thanks to the newly launched research vessel (R/V) Isabu of the Korea Institute of Ocean Science and Technology (KIOST), and the acquisition of a contamination-free PRISTINE (NIOZ, NL) ultraclean seawater sampling system […]

Neural network as tools to replace oceanic data deficiencies

The importance of the cycle and speciation of nitrate and its isotopes (δ15N) in the ocean does not have to be demonstrated anymore. In an attempt to overcome the difficulty […]

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 […]

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 […]
