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 on 8 profiles across the Mediterranean Sea. Contrasting with what is observed in the open ocean: Depth profiles of these tracers are non linear, indicating […]

Complex cobalt story in the Mediterranean Sea

Dulaquais and co-authors (2017, see reference below) propose the first comprehensive study of cobalt behaviour in the Mediterranean Sea, work conducted in the framework of MedBlack GEOTRACES cruise (GA04N). They measured the following cobalt (Co) fractions: soluble (sCo<0.02 μm), dissolved (DCo<0.2 μm), colloidal (cCo, as DCo minus sCo), and particulate (pCo>0.2 μm). While soluble Co […]

Helium isotopes help to constrain high-resolution model dynamics in the Mediterranean Sea

The terrigenic helium isotope distribution was simulated for the first time in the whole Mediterranean Sea, using a high-resolution model (NEMO-MED12) at one-twelfth of a degree horizontal resolution (6–8 km). Together with providing valuable constraints on the crustal and mantle helium fluxes, the simulations and their comparisons with observations provide a new technique for improving […]

The potential of coupling high-resolution circulation models and geochemical tracers: example of the Mediterranean Sea

For the first time, a numerical study proposes the simulation of the anthropogenic tritium (3H) invasion as well as the distribution of its decay product helium-3 (3He) using a high-resolution regional circulation model (NEMO 1/12). Comparison with the numerous set of data acquired in the framework of different Mediterranean Sea transects conducted on the last […]
