Abstract
Oceanographic measurements, sediment and biological sampling were undertaken in several studies of the southern and western intertidal and subtidal coastal zones of the island of Igloolik, Nunavut. Coastal areas were composed of raised shingle beaches with narrow gravel intertidal zones. Locations with flat low-lying intertidal areas were underlain by bedrock with a thin veneer of fines and gravels, no marine fauna were ever collected from these sites. Subtidal zones with unconsolidated substrates were host to a range of benthic fauna while those with rocky substrates had more limited communities dominated by epifauna. Eighty-three benthic marine invertebrate species were identified in a detailed study of Turton Bay, a shallow embayment that opened to the south and contained the town site of Igloolik. Overall oceanographic conditions did not appear to be greatly influenced by the shallow depths (23.4 m), dissolved oxygen values remained high throughout the sample season, although temperatures decreased and salinity increased slightly with depth. The shallow subtidal zone (<5 m) was characterized by a thin sandy surface veneer overlying bedrock and was an extension of the intertidal zone and much affected by ice action during breakup. Sediments fine with depth but were poorly sorted throughout the bay.
