UNL’s Anatoly Gitelson will delve into aquatic ecosystems in a 3:30 p.m., Sept. 21 talk in the Hardin Hall Auditorium. Gitelson’s lecture, “Physically Based Models for Remote Estimation of Terrestrial and Aquatic Ecosystems Production,” is part of the School of Natural Resources’ 2011 Fall Seminar Series.

Gitelson is a physicist, remote sensing specialist, and professor of agronomy and horticulture. He is also part of the Center for Applied Land Management Information Technology in the School of Natural Resources.

Biological processes on land and in the oceans strongly affect the global carbon cycle on all time scales. In both components of the biosphere, oxygenic photosynthesis is responsible for virtually all of the biochemical production of organic matter. Mechanisms of and constraints on photosynthesis on land and in the oceans are similar in many respects. Integrating conceptually similar models of the growth of terrestrial and marine primary producers, Gitelson will present a unified approach to estimation of primary production of organic matter by terrestrial and aquatic ecosystems based on satellite measurements.

Gitelson received a master’s degree and doctorate in radio physics from Russia’s Taganrog Institute of Radio Technology. His main research interests are radiative transfer in the atmosphere, water, and vegetation, as well as remote sensing of aquatic and terrestrial environments.

Before joining UNL in 2000, Gitelson headed the Department for Environmental Physics and Energy Research at the J. Blaustein Institute for Desert Research, Ben-Gurion University of the Negev, 1997-2000. In 1998 he received the Israeli State Award for Outstanding Contribution to Israeli Science. Gitelson also held scientific posts in the former USSR.
