Chemical Oceanography of Frontal Zones

Igor Belkin holds a PhD in Oceanography from the Shirshov Institute of Oceanology, Moscow, Russia. Since 1973, he has been studying oceanic fronts, currents, and eddies in all five oceans from 72 DegreesN to 78 DegreesS, having spent five years at sea in 16 expeditions, including a six-month drift on the ice island "North Pole-22" in the Arctic Ocean. He also studied the Great Salinity Anomalies in the North Atlantic and climate change in the Large Marine Ecosystems around the world. Since 1997, he has been associated with the Graduate School of Oceanography, University of Rhode Island, Narragansett, RI, USA. Since 2019, he is Professor of Oceanography at the College of Marine Science and Technology, Zhejiang Ocean University, Zhoushan, Zhejiang, China, where he continues his global survey of oceanic fronts and eddies.
