Recent projects

Foraminifera biogeography

Data on planktic foraminifera assemblages in the ocean sediments exist in several published databases. There is a need for a new, corrected compilation and publication of this data in an up to date format.
Multi-Plankton-Sampler

Plankton sampling

I work on the constant improvement of our Multi-Plankton-Sampler. Next to the addition of new sensors this includes the development of our own control software.

Transferfunction
methodology

I am looking for ways of improving current transfer functions methodology.

Red Sea paleoceanography

I am working on the completion of planktic foraminifera fauna downcore record of a core from the central Red Sea.
