Koralen van 'Darwin' verklaren schommelingen in mondiale opwarmingssnelheid
De aarde warmt snel op door de menselijke uitstoot van broeikasgassen, maar ook natuurlijke factoren spelen een rol bij variaties in de opwarmingssnelheid. Metingen van de mondiale oppervlaktetemperaturen laten soms onderbrekingen zien in de…

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…

NIOZ@Sea: Black Sea cruise
This edition of NIOZ@Sea is a series of blogs from the Black Sea cruise of our scientists on board research vessel Pelagia. The Black Sea is the largest permanently stratified sea in the world. This is ideal to study the structure of microbial…
