Nutrient Chemistry of the Arctic Ocean

AWI scientist Sinhué Torres-Valdés observed the nutrient chemistry of the Arctic Ocean on an expedition as part of the PEANUTS project (Primary production driven by Escalating Arctic NUTrient fluxeS). The SCRIPPS Institution of Oceanography led the expedition in 2018. The results have now been published in a paper in the journal Nature Communications. The PEANUTS project is funded by the Changing Arctic Ocean Program (CAO).

Arctic Ocean: Greater Future acidification in summer

Over the past 200 years, our planet’s oceans have absorbed more than a quarter of all anthropogenic carbon dioxide from the atmosphere. As a result, their acidity has increased by nearly 30 percent their [...] recently demonstrated. If this comes to pass, it could have far-reaching consequences for life in the ocean, as they report in the journal Nature.
