Professor D.Sc. Rune Dietz (RD), Department of Bioscience, Arctic Research Centre, Aarhus University. RD was educated at University of Copenhagen in 1981 and has now worked more than 30 years of experience with the work on contaminants and marine mammals. RD is a member of IUCN Polar Bear Specialist Group and HELCOM Seal Specialist Group. In addition RD has been responsible for the Arctic Monitoring and Assessment Programme (AMAP) assessments on heavy metals and Mercury since 1995 and has contributed to the AMAP POP Effect and time trend Assessment. RD has recently been responsible for a number of larger international programmes including the IPY (International Polar Year) programme BEARHEALTH, ARCTIC (Advanced Research on Contaminant Transfer, Impact and Consequences) and PELATES (Population Effect Levels in Arctic Top EcoSystems), OCEANS12, Species at Risk, PREDATORS and Unexpected. RD has extensive Arctic field experience over the last 30 years and has been involved with satellite tracking of marine mammals during the last 20 years. RD has been tracking more than 400 animals from14 primary marine mammal species with satellite tags and others data loggers. RD has been responsible for a large part of the samples stored in Department for Arctic Environment Data Bank, which were initiated more than 25 years ago. In the later years examination of historic samples have revealed the temporal trends of Mercury in polar bears and other top predators before the industrial revolution (>150 years). RD have also published results on all contaminant groups including conventional POPs, brominated flame retardants and perflourinated compounds covering more than three decades in e.g. polar bears and ringed seals. Since 1999 the contaminant work has been linked with effect studies from the Arctic regions, which are the longest lasting Arctic effect studies. RD was also responsible for the controlled effect study on sledge, where the effects of contaminants from the Greenlandic food were investigated. Within the Arctic Research Center (ARC) RD has become responsible for combining wildlife and human health in Greenland. RD has published 266 scientific papers and another 15 have been submitted or are in press. RD has produced a similar number of conference contributions and technical reports. RD is a member of the editorial board of SM Journal of Environmental Toxicology and co-editor of Archives of Environmental Contaminants and Toxicology. RD has an extensive collaboration with science colleagues, of which he has published with more than 200 colleagues. RD is or has been supervisor, co-supervisor and coauthored with 40 Masters and PhD students and Post Docs in Denmark, Norway and Canada. RD has a Scopus H-index of 41 and a Google H-index of 53 by February 2016 as well as 8937 citations.
