Researchers working at Wittbülten have the opportunity to stay in affordable apartments, conduct research, process samples professionally in the laboratory, and evaluate data.

The diverse fields of research on site include the island's habitats, which are within easy walking distance of the research center. These are the extensive beach areas, foredunes with beach grass, white dunes with beach grass and beach thistle, extensive gray and brown dunes, and salt marshes with adjacent mudflats.

The Ostplate, a very young and dynamic habitat, borders the east of the research center. It is particularly interesting because the sandy area, which was still bare in 1950, is in the process of becoming an island and makes up more than half of the island's body. Its zoning and habitats still show their originality and are now located in the quiet zone of the national park.

Other possible subjects of study include freshwater lenses, species diversity of flora and fauna, marine macrozoobenthos, climate adaptation strategies, and Spiekeroog as an example of sustainable tourism/sustainability development.

Work in the national park must be approved by the Lower Saxony Wadden Sea National Park Administration.
