Sedimentology of an Arctic Basin: M44-91/11E-PDF
Itirbilung Fiord, Baffin Island, Northwest Territories /
"Itirbilung Fiord was investigated using geophysical, oceanographic and sediment surveys in 1982, 1983, 1985, and 1987. Itirbilung typifies a deep arctic basin that experiences episodic sedimentation events, cycled principally by nival and glacier melt with punctuations by mass-sediment failures. Aeolian transport of sediment into the fiord basin may also be large, possibly four times the sediment volume transported by the Itirbilung River. A Quaternary fill of greater than 150 m is located in two of the four basins. Paleohydraulic calculations suggest that for the period 8400 to 6000 years BP, Itirbilung fiord received up to five times the present rate of fluvial delivery, reflecting the ablation of the Late Foxe Ice Sheet. Between 6000 and 150 years BP, a time of Neoglacial ice storage, sediment yield was much lower"--Abstract.
