ACKNOWLEDGEMENTS Development of this system was made possible by financial support from the Danish Environmental Protection Agency as part of the environmental support program DANCEA – Danish Cooperation for Environment in the Arctic and The University of Southern Denmark, Department of Chemistry. Stihl GmbH (Switzerland and Sweden) provided us with a BT 360 two- man motor, extension rods for initial laboratory and field-testing of the prototype corer, as well as relevant technical specifications. AN IARC grant (to 3d author) provided for the fieldwork on Bathurst Island and for this work, and Stihl Canada loaned us a BT 360 two-man motor and provided technical manuals, oil, and spare parts (thanks to K. Eberle, G. Quigg and E. Zynomirski). Special thanks to Weston Blake Jr. for his assistance while we were preparing the sampling plans, testing and building the corer and for providing his original peat cores from Bathurst Island for testing, in addition to critically reading this manuscript. For the fieldwork phases we would like to thank our scientific colleagues: Dr.’s A. Cheburkin, O. Bennike and E. Warncke. The help from team members who did not take part in the fieldwork, especially Dr. C. Lohse, N. Givelet and G. Le Roux (esp. Fig. 4 and 5.) is gratefully acknowledged. M.E.G. was supported by a Ph.D. fellowship from NERI and the Danish Research Agency, as a graduate student at the University of Copenhagen (Global Change Initiative Graduate School) under the academic supervision of H. Skov, S. Lindberg, and O.J. Nielsen, for which he is most grateful. 9
