Abstract: The remote and inaccessible nature of oceanic habitats have largely precluded direct observations of their inhabitants. However, submerged echosounders can provide information on organismal behavior and ecosystem processes even at mesopelagic depths and beyond. By deploying autonomous echosounders, which may be battery powered or cabled to shore for power and transmission of data, ecosystem processes and organisms can be studies at timescales of seconds to years. In this talk I will present data on the behavior of both deep-living (mesopelagic) and epipelagic fishes, as well as illustrating the type of data that can be obtained in studies of plankton.  

Bio: ‚ÄčProfessor Stein Kaartvedt earned his PhD in marine biology at the University of Bergen, Norway. He was affiliated with the University and the Institute of Marine Research, Bergen, until moving to Woods Hole Oceanographic institution, USA, for a post-doctoral scholarship. Kaartvedt thereafter became professor at the University of Oslo, Norway, where he also has served as Chairman for the Biology Department. Kaartvedt was founding Faculty at KAUST, and spent 5 years as professor in marine science at the Red Sea Research Center, also acting as associate director at the center. He is currently professor in marine science at the University of Oslo.
