Gulf stream eddies are fertilizing the Western Atlantic Ocean
Tim Conway and co-authors (2018, see reference below) show that Gulf Steam eddies can provide an extra supply of iron, and nutrients such as phosphate and nitrate to the iron-starved […]

High mesopelagic carbon remineralization traced by particulate biogenic barium in the North Atlantic Ocean
The high resolution section of particulate “excess Ba” (Baxs) measured by Lemaitre and co-authors (2018, see reference below) along the GEOVIDE GA1 section (R/V Pourquoi Pas? spring 2014) confirmed the […]

Arctic rivers are discharging organic matter enriched in mercury to the Labrador Sea
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 […]

Where, how and which trace elements are released from dust at the sea surface?
Alex Baker and Tim Jickells (2017, see reference below) propose to answer to this question thanks to analysis of aerosols collected in the framework of the Atlantic Meridional Transect (AMT). […]

Widespread nutrient co-limitation discovered on GEOTRACES cruise
Browning and co-workers (2017, see reference below) find that multiple nutrients must be supplied to stimulate phytoplankton growth on the southeast Atlantic GEOTRACES GA08 cruise. The paper has been published […]

Tracing scavenging intensity with the original coupling between scandium, yttrium and lanthanum in surface waters
The first basin-wide surface scandium (Sc), yttrium (Y) and lanthanum (La) concentration data in a section across the North Atlantic subtropical gyre (2011 GEOTRACES GA03) is reported by Till and […]

Manganese in the west Atlantic Ocean in the context of the first global ocean circulation model of manganese
Marco van Hulten and co-workers (2017, see reference below) ran a global ocean model to understand manganese (Mn), a biologically essential element. The model shows that: (i) in the deep […]

Surprising cadmium isotope results north of the Subantarctic Front in the South West Atlantic Ocean
Xie and co-workers (2017, see reference below) report cadmium (Cd) isotopic compositions from five stations and 15 tow-Fish surface waters from 50ºS to the equator along GEOTRACES GA02 Leg 3. […]
