Krisch and colleagues present a flux budget for micronutrient exchange between the Arctic and the North Atlantic Ocean.
Xiang and co-workers compiled full ocean-depth size-fractionated particle data from three recent U.S. GEOTRACES cruises.
They have developed optical sensors for particulate inorganic carbon concentration.
Among other findings, authors find that the new opal flux is roughly a factor of two increase over previous estimates having important implications for the global silicon cycle.
Authors estimated particulate trace element export fluxes and residence times in the upper North Atlantic Ocean
In the ocean, the residence time of mercury (Hg), is largely driven by two removal mechanisms: evasion to the atmosphere and downward export flux with settling particles. The later was […]
A complete review of published and new water column profiles of thorium-230 (230Th) and protactinium-231 (231Pa) concentrations and neodymium (Nd) isotopic compositions collected in the Amerasian Basin of the Arctic […]
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 […]
In the framework of GEOVIDE-GEOTRACES GA01 cruise (spring 2014), Cossa and co-workers (see reference below) measured the first high-resolution mercury (Hg) distribution pattern along a transect from Greenland to Labrador […]
