Tracking the sea ice exported from the Siberian Shelf to the Arctic Ocean
An original method based on the use of the couple salinity – δ18O allows determining the fractions of water that had been removed as ice across the shelf and the […]
Science Highlights
Some recent GEOTRACES science findings are reported below.
GEOTRACES publishes the motivations and description of its first Intermediate Data Product
GEOTRACES proposes an article that describes its first integrated and quality controlled Intermediate Data Product 2014 (IDP2014): the digital data package and the eGEOTRACES electronic Atlas that provides section plots and […]
Metal contents of North Atlantic phytoplankton across environmental gradients
Twining and co-workers (2015, see reference below) provide the first direct measurements of metal quotas in phytoplankton from across the North Atlantic Ocean (US GEOTRACES GA03), known to be subjected […]
New insights into global barium cycling from the first barium isotope data for seawater
A new method developed by Horner and co-workers (2015, see reference below) allows for the determination of dissolved barium (Ba) isotopic compositions in seawater using nanogram quantities of Ba. The […]
Large fluxes of dissolved aluminium exported from the coast to the ocean
In the Eastern China Sea (ECS), the continental shelf serves as an important source of dissolved aluminium (DAl) for the overlaying waters via resuspension of sediments and benthic fluxes. This […]
Multiple controls on the dissolved aluminium fate in the Western Atlantic Ocean
Thanks to the most impressive set of dissolved aluminium (Al) and silicon (Si) data ever published in the Atlantic Ocean, Middag and co-workers (2015, see reference below) are thoroughly scanning […]
Do you know that coastal phytoplankton is able to adapt to iron limitation?
Oceanographers have long understood that phytoplankton in the open ocean tend to have lower iron (Fe) requirements and/or more strategies for obtaining Fe from the environment. Adding a new twist […]
Decoupling between dissolved zinc and silicon in the North Atlantic Ocean driven by mixing of end-members
Roshan and Wu (2015, see reference below) reveal that the correlation between dissolved zinc (Zn) and silicon (Si) is relatively weak in the North Atlantic Ocean (GA03 US section). They […]
Changing the cadmium : phosphorus paradigm?
The well-established strong linear relationship linking dissolved cadmium (Cd) and phosphorus (P) concentrations in seawater is at the origin of the attraction of Cd as a proxy for PO4 in […]
