On cold winters, warm summers and life in the sea
|Date||11 December 2019|
During this Christmas lecture, we will explore how climate change is presently impacting life in the sea. Increase in water temperatures, for example, results geographical shifts of marine organisms to colder waters, shifts in ecological interactions (such a prey-predator relationships) and decline in average size of marine organisms. In addition, changes in rainfall influence coastal systems whilst acidification leaves its traces on oceanic and coral reef communities worldwide. Climate-driven shifts in marine food webs result in shifts in marine ecosystem functioning and services, which should be taken into account when exploring and exploiting life in the sea. These ongoing changes will be illustrated by recent findings occurring in various oceans and seas in the world.

In 1994, Katja defended her PhD thesis on the seagrass dynamics, based upon fieldwork in the Wadden Sea and in Mauritania. Hereafter, she studied coastal food web dynamics in general and the interactions between microscopic algae and bivalves in particular (amongst others in the Wadden Sea and the Venice lagoon). Working at NIOZ since 1993, she obtained and coordinated multiple large research projects on, amongst others, impacts of coastal fisheries, sustainable use and conservation of marine living resources, designing multiple platforms to determine primary productivity of coastal systems, climate change impacts on the marine environment, long-term ecosystem research and shellfish aquaculture. In 2013, she became a board member (portfolio Ecology) of the Wadden Academy. The Wadden Academy aims to furnish the scientific foundations for an economically and ecologically responsible future in the Wadden Sea Region, a World Heritage Site. Since 2014, she is affiliated with the Utrecht University, where she became a Professor by Special Appointment on “Productivity of Coastal Marine Ecosystems” in February 2018.
