Opcn to C\eryulle intercsted In the Arctic. these met'tings kive cOllsistecl of a series nr talk:-, ilflc) postcr<;essio!1s covt'llng i!ll aspects of high-Lltitudc environments, past and present Like the prniolls i\rctic Workshops. this workshClp also include presentJtions on Arctic and l\ntarctic clim:lte. archeology, environmental geochemistry, geomorphology, hyd rolog y . gl,l(iology, soils , ecology, oceano graphy , and QuaternJry histelry . Thm, the workshop offers all opportunity for stimu!ating discussions between scientists studying various aspects of high-IJtitucle cliIl1Jtes and environments. The first Arctic Workshop w as organized by J ohn Andre\vs Jt INSTAAR in 1970 to give grJduate students an opportunity to present their ongoing research, obtain some ex perience in public spe aking , and to get feedback from more senior researchers. ]n keeping with this tradition, the U.S. National Science Foundation and the Research Council of Norway have sponsered the participation of 4S graduate students from all over the world to this meeting , We are extremely pleased to have such a high participation of gradu ate students - making up nearly half of the worksh op participants. We hope to be as much inspired by these young minds as we can inspire them further in their wonderfully exciting guest to understand high latitude climates ,md environments. The conferenee is being held at the Polar Environmental Centre. The Centre for the Enviro nment ,md co - operation in the Polar Areas and the Barents region - The Polar Environmental Centre - is Norw ay 's new centre of research, environmental monitoring and a d visory services in the Northern Region and the Arctic/ Antarctic . The conveners (Stein Bondevik, :JvIorten Hald, Elisabeth ]saksson, Nalan Ko\, Tore Vorren) would like to thank our sponsers: the Norwegian Polar Institute , the University of Tromsø, the Research Council of Norway and the U.S. National Science Found ation. We also offer our sincere thanks to Anne Kibsgaard , who did an excellent job as secretary for this workshop, Ellen Berg, who assisted A Ki bsgaard , and Audun 1gesund , who was respansible for the web layout . We hope the 33rd Annual Arctic Workshop \Vill be a rewarding interdisciplinary meeting for you on a variety of Arctic research thernes. WeJcome to Tromsø!
