Science Highlights

Estuary solid loads and solid-solution exchanges yield considerable dissolved trace metal enrichments

Based on a thorough investigation of water and suspended sediment samples collected over two years and a six seasons, Samanta and Dalai (2018, see reference below) show that the annual […]

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 […]

High production of methylmercury in the anoxic waters of the Black Sea

As part of the GEOTRACES MedBlack cruise, the research vessel Pelagia occupied 12 full-depth stations in the Black Sea along an East-West transect between July 13th and 25th, 2013. In […]

Using ICPMS/MS to determine manganese, iron, nickel, copper, zinc, cadmium and lead concentrations on less than 40ml of seawater

Jackson and co-workers (2018, see reference below) first did a classical offline preconcentration of small seawater aliquots using a SeaFast system. More innovative is the use of a state of […]

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 […]

Astonishing protactinium and thorium profiles in the Mediterranean Sea

In the framework of the GEOTRACES cruise along the GA04 section in the Meditterranean Sea, Gdaniec et al. (2018, see reference below) measured thorium (Th) and protactinium (Pa) isotope distributions […]

Surface South Pacific ecosystems reflect the availability of the nutrients iron, nitrate and phosphate

Thanks to a high resolution section across the South Pacific (150°E-150°W, GEOTRACES GP13 cruise), Ellwood and co-workers (2018, see reference below) identify that the gradient of sources and fates of […]

Why did the concentration of atmospheric carbon dioxide rise so much and so quickly during the last deglaciation?

During the Last Glacial Maximum, the deep southern Pacific waters were stratified, efficiently accumulating old, CO2 rich waters. Basak and co-authors (2018, see reference below) measured neodymium isotopes in sediment […]

Particle distribution in repeated ocean sections and sediment resuspension

This is the first compilation of an expansive data base of transmissometer data on a decadal period of time. More than 7376 stations have been analyzed for “cp” value, a […]
