Additional nutrients intensify dead zones in oceans
As more and more nutrients from land and air enter the world’s oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that PhD student Zoë van Kemenade, an organic geochemist at NIOZ, draws from…

NIOZ@SEA | GoM2020 expedition in the northern Gulf of Mexico
The mighty Mississippi river and its Atchafalaya branch bring in vast amounts of sediment material and dissolved nutrients into the northern Gulf of Mexico. By doing so, these rivers have an enormous impact on the chemistry and biology in the water…

NIOZ@SEA | 64PE450
Along the southwestern African continental margin off Namibia and Angola coral mound provinces were found during the Meteor (ANNA) cruise in 2016. While the corals in the south along the Namibian margin were mostly fossil frame structures, the corals…

NIOZ@SEA | FUNAMOX expedition in the southeast Atlantic
Off the coast of southwest Africa, currents force cold deep waters full of essential elements required for ocean life to the surface. This so-called upwelling has enormous impacts on the chemistry and biology of the water and sediment. We are sailing…
