Leibniz Centre for Tropical Marine Research (ZMT), Bremen

The Leibniz Centre for Tropical Marine Research (ZMT) GmbH (www.leibniz-zmt.de) is an independent research and teaching institute that provides scientific knowledge for the protection and sustainable use of tropical coastal ecosystems. To this end, we work in an inter- and transdisciplinary manner with our partners in the tropics. The ZMT is a member of the Leibniz Association.

We aim to advance our understanding of groundwater availability across the world’s islands. Building on previous work in our research group, the project will develop a comprehensive global database of island hydrogeological characteristics and adapt an existing global groundwater modeling framework (Nazari et al., 2025) to capture the unique conditions of insular environments. The results will provide new insights into groundwater availability and recharge dynamics under present and future climate scenarios, supporting sustainable water management in vulnerable island regions.

The working group Submarine Groundwater Discharge is seeking to fill an opening for a doctoral candidate (subject to release of funds).
