The circulation loop in the North Atlantic and Arctic oceans depicted by the artificial radionuclides
Three articles from three cruises highlighted here! Atlantic waters have been recently recognized to play an increasing role in reducing sea-ice extent in the Arctic Ocean at a rate now […]
What do the first 236-Uranium data reveal in the Arctic Ocean?
Casacuberta and co-authors (2016, see reference below) propose the first set of data for the artificial radionuclide 236-Uranium (236U) in the Arctic Ocean. The novelty of this study compared to […]
The potential of anthropogenic 236-Uranium as a new and transient oceanographic tracer demonstrated in the North Atlantic
236-Uranium (236U) is present on Earth due to natural and anthropogenic production. However, the estimated inventory of anthropogenic 236U (106 kg) largely exceeds the natural one (30 kg). Releasing even […]
