Dr. Hans van Haren

Senior Scientist

Within the scientific discipline of physical oceanography my interest focuses on the dynamical effects of density variations, ranging from diapycnal mixing via modification of oscillatory currents to internal waves. Over the years my research was always based on the analysis of measurements obtained at sea, with emphasis on those from moored instrumentation.

Through the development of specialized instrumentation of high-resolution temperature sensors in tight collaboration with NIOZ technicians, my research interest extended to very high-frequency nonlinear fronts of internal waves and their impact on deep-ocean mixing. This led to various searches on internal wave breaking over diverse sloping bottom topography, including sediment-internal wave interactions.

The effects of internal wave mixing on deep-sea life led to some new observations on very deep plankton migration following the moon and sun at depths where not a glimpse of surface light penetrates.
