INTRODUCTION

Overview and history The 41st Annual International Arctic Workshop will be held March 2-4, 2011, at the Université du Québec à Montréal, Québec, Canada, and hosted by GEOTOP and Centre d’études nordiques. This workshop has grown out of a series of informal annual meetings started by John T. Andrews and sponsored by INSTAAR and other academic institutions worldwide. In keeping with this tradition, there are no formalized topics and the workshop has been organized around themes developed from the abstracts submitted. Website http://www.arcticworkshop2011.uqam.ca/ On-site registration Please check in or register on (1) Tuesday evening at the Icebreaker between 5 – 8pm, or (2) Wednesday morning between 8:00 – 8:30am. At registration you will receive the Program only (no Abstracts volume) as well as other workshop information. Posters At registration you will receive information on where to set up your poster. Please put it up during the morning or lunch break on the day of your session, and remove it at the end of your poster session. Presentation Files (i.e., PowerPoint) Please load your presentation onto our computer during the Icebreaker on Tuesday 5 – 8pm or the Check-In/Registration on Wednesday 8:00 – 8:30am. Time during breaks is limited. Support Student financial assistance is available thanks to support from the NSF, INSTAAR, GEOTOP and CEN. The special session and the general public talk were made possible thanks to the contribution of the Institut des sciences de la mer de Rimouski (ISMER). Additional support was provided by the UQAM Faculty of sciences and the Conseil franco-québécois de coopération universitaire (CFQCU).
