ARCTIC The Coastal Morphology and Sedimentology of Cape Hatt Peninsula
ABSTRACT. A small peninsula located on northern Baffin Island was selected as the site for an experimental oil spill. The experiment required three similar bays, one to serve as control a d two to compare the fate and behaviour of oil and an oil-dispersant mix spilled in the nearshore zone. Geomorph...

| Summary: | ABSTRACT. A small peninsula located on northern Baffin Island was selected as the site for an experimental oil spill. The experiment required three similar bays, one to serve as control a d two to compare the fate and behaviour of oil and an oil-dispersant mix spilled in the nearshore zone. Geomorphic and sedimentologic observations indicate that (1) the shoreline sediments of Cape Hatt are reworked glacial deposits, (2) bays facing Eclipse Sound are the most exposed to wave and ice action and those of Z-Lagoon are the most sheltered, (3) there is a westerly sediment transport direction in the bays of Eclipse Sound, a winnowing of fines from the most exposed bays of Z-Lagoon and several transport directions in Ragged Channel and (4)ice action is the most important process at Cape Hatt. Qualitative assessment of these features was used to recommend that Bay 10 be used for control, Bay 9 for the oil-alone experiment and Bay 11 for the oil-dispersant mix experiment. Geological features, however, reflect the integration f all processes operating at Cape Hatt over long periods f time and do not warrant as high a priority as meteorological and o eanographic criteria in the final selection of bays for the BIOS Project.

Une petite p6ninsule situ & 1 l’extremitk nord de I’ile de Baffin, a CtC choisie pour y conduire un diversement experimental d’hydrocarbure. L’exgrience necessita trois baies semblables, une devant &tre utilisee comme thoin, et deux pour cornparer les consequences d’un deversement d’hydrocarbure et d’un melange d’hydrocarbure et d’un agent de dispersion. L’Btude gkomorphique et skdimentologique du cap Hatt demontra que (1) les sediments des plages du cap Hatt sont constitues d’ancient d6pBts glaciaires modifies par I’action des vagues et de la glace, (2) les plages adjacentes 1 Eclipse Sound sont les plus exposees 1l’action des vagues et des glaces, et ceux du lagon “Z ” les plus abritkes, (3) les sediments des ... |
