Environmental bottom investigations of the Arctic Shelf are to determine the anthropogenic component and the degree of its impact to biota in the course of the sedimentation process. Hereby, the main focus in Geoecology of the Western Arctic Shelf of Russia is on analysis of sources of supply, pathways of migration, mechanisms of transformation and accumulation of pollutants as well as on the selection of the criteria of assessment of the bottom environment at different levels.
Three groups of pollutant sources are distinguished: exogenic, endogenic and aquapolytechogenic. This volume, Geoecology of the Western Arctic Shelf of Russia, reports on multidisciplinary environmental investigations carried out by SIA Sevmorgeologia in the Western part of Arctic through 1991-2010, with more than 1100 complex stations.
A variety of geochemical parameters and criteria were monitored to enhance the existing methods of assessment including the background concentrations of major groups of contaminants (chlororganic compounds, heavy metals, phenols, HC, PAH, SSAS, radionuclides) in water and sediments, calculated for various levels of complexity of geological objects (transregional – for Barents Sea, regional – for Pechora and White Seas, St. Anna Trough, local – for Shtockman and Prirazlomnoe fields, mouse of Pechora, Ob, Enisej Rivers, and special polygon-dumpsites of nuclides).

Gennady Ivanov, principal scientist, doctor of geological-mineralogical sciences, is a graduate of the Leningrad Mining Institute. For 27 years he was involved in the prospecting and exploration of the ocean floor in NIIGA, All-Russia Research Institute of Geology and Mineral Resources of the World Ocean. He worked as a senior technician and became head of division. From 1987 to 1990, he worked as an expert in the joint (through CEA) organization A"InteroceanmetalA", Szczecin, Poland. Since 2004 he runs "Sevmorgeo" as chief geologist, deputy director for science, principal scientific officer. He was director of several international collaborative projects with research organizations in Germany (Alfred Wegener Institute, Geomar), USA (Naval Research Laboratory), Canada (Bedford Institute of Oceanography), Norway (Aqua Planniva), UK (British Petroleum), etc. Conducts teaching work with students of the Faculty of Geology of the St. Petersburg University, reading them a course of lectures on "Geo-ecology of the oceans and seas".
