My principal research interests of studying internal waves, turbulence and turbulent exchange through oceanographic observations have roused interest in the development of seagoing instrumentation. The available facilities and enthusiasm of technicians at NIOZ and Post-doctoral fellows like Louis Gostiaux, Andrea Cimatoribus and Frederic Cyr have allowed a creative atmosphere. In close collaboration with electro-technicians, especially Martin Laan, software-engineer Frank van Maarsseveen and fine-mechanics engineers Johan van Heerwaarden and Roel Bakker NIOZ high-resolution temperature sensors have been developed. Together with many NIOZ-sea-technicians led by Lorendz Boom they were also involved in the development of new mooring techniques like thin-line moorings, self-unrolling moorings and (un)foldable 3D moorings.
