AbstractThe Geological Survey of Canada's project SAFE (Sedimentology of Arctic Fiords Experiment) was initiated in 1981 and is being carried out in a series of fiords situated along the east coast of Baffin Island. SAFE emphasizes the study of the Quaternary history and modern processes of arctic fiord environments. Project participants are interested in evaluating the significance of the comparatively rapid process rates and of the high-resolution sedimentary records that typify these settings.
The key objectives of SAFE include: 1. To understand sandur development and the character of the resultant facies. 2. To understand the time-dependent influences of rivers, tides, waves, wind and deep-water renewal on fiord circulation and sedimentation patterns. 3. To use the geological record of raised marine deposits in establishing late Quaternary history within and between fiords.
Following a reconnaissance of1 0 fiords along the east coast of Baffin Island in 1982, 3 were selected for detailed study during the 1983 field season (Cambridge, Itirbilung, McBeth). The 1982 and 1983 investigations utilized the oceanographic research vessel CSS Hudson as an operations base. During both surveys, core sampling, CTD profiling, geophysical mapping and other heavy work were carried out from the Hudson up to the 100 m isobath. The shallow water operation was supported by two launches outfitted with equipment to carry the oceanographic and geological programs into nearshore uncharted areas. Field parties were landed to study raised marine deposits and glacial features. The 1983 survey was preceded by a helicopter-supported program that succeeded in mooring and recovering several strings of current meters and sediment traps near the heads of Cambridge and Itirbilung fiords.
