Abstract
Seismic reflection surveys using a compressed air source in nine fiords on Baffin Island provide information on the amounts of sediment deposited and the relation of sedimentation to events during Late Quaternary glaciation. Five sedimentary facies can be recognised in the seismic records: (1) a basal facies of ice contact glacial sediment including moraines and deformed, stratified, glaciomarine sediment; (2) a lower glaciomarine facies of well-stratified sediment deposited in an ice-proximal environment; (3) a facies of acoustically transparent sediment deposited in a lower energy environment farther from sources of glacial sediment; (4) and upper, well-stratified facies similar to facies B and also interpreted as ice-proximal; and (5) a thin facies of modern sediment on top of the other materials. These facies are tentatively correlated with glacial events on eastern Baffin Island.
