The forerunner of the Royal NIOZ in Yerseke, the Centre for Estuarine and Marine Ecology (CEME), started in 1957 as Delta Institute for Hydrobiological Research under the flag of the Netherlands Institute of Ecology (NIOO). Working together with universities and research partners CEME was a central institute to Dutch research in coastal and estuarine systems.
In 2012 the Royal NIOZ merged with the Centre for Estuarine and Marine Ecology. Focusing on an integrative scientific approach to ecosystems in brackish and salt water, research programmes of Royal NIOZ Yerseke aim to unravel fundamental processes in material cycles. Addressing the protection and the restoration of valuable ecosystems is a secondary research objective.
At the Yerseke facilities, about 120 people are working within the science department Estuarine and Delta Systems (EDS). The focus is on seagoing research, for which the institute uses its own research fleet. This fleet consists of four modern ships, headed by the ocean-going RV Pelagia. Seaport Texel is the homeport.
