New Study on Molybdenum & Uranium Inputs in the Atantic Ocean

Sandra Pöhle together with Andrea Koschinsky and alumna Imelda Velasquez recently published a study titled “Do desert dust input and pronounced oxygen minimum zones act as sources or sinks for dissolved molybdenum and uranium? A GEOTRACES study in the eastern Atlantic Ocean.” in the journal Marine Chemistry.

The study evaluates samples from two GEOTRACES research cruises: GA11 – NE-Atlantic affected by Saharan dust and the Mauritanian upwelling and GA08 – SE-Atlantic affected by Namibian dust and the Benguela upwelling and finds that the expansion of less oxygenated waters with a potential shift towards euxinic conditions and more extensive dust events in the future due to e.g. climate change may affect the distribution and potentially isotopic signatures of Mo and U.
