Objectif(s): The major objective is to increase our basic understanding of certain permafrost features and processes, such as; the growth of ice wedges, aggradational ice, massive underground ice; mass wasting on hillslopes; the growth of permafrost from the very beginning in the bottom of a drained lake; pore water expulsion, freezing point depression, and groundwater flow. The work is believed to be important because it seeks to answer many basic origin and process questions that are only possible if field work and data collection are carried out summer and winter on a long-term and continuing basis. The motivation is scientific curiosity.
Description du projet: Transportation to and from the field sites will be by helicopter, either from Tuktoyaktuk or Inuvik, to and from Garry Island and Illisarvik (West Point, Richards Island). Most of the equipment used in the field is for measurement purposes , such as surveying equipment for precise height, distance, and tilt determinations of bench marks already installed across ice wedges and elsewhere, temperature measuring equipment for obtaining small soil and peat samples to a depth of about 1 to 2 m. Field dates will probably be in August with perhaps a visit in the fall, such as November. No heavy equipment nor are any wildlife involved in the study.
