Glacigenic mudflows on the Bear Island submarine fan / P.R. Vogt, Kathleen Crane, E. Sundvor.

Title: Glacigenic mudflows on the Bear Island submarine fan / P.R. Vogt, Kathleen Crane, E. Sundvor.
Author(s): Vogt, P. R.
Crane, Kathleen.
Sundvor, E.
Date: 1993.
In: Eos : transactions, American Geophysical Union. (1993.), Vol. 74(40) (1993)
Abstract: Fan dominates 3.1x10⁵ km² accumulation zone extending from south-west Barents Sea shelf to south Lofoten abyssal plain. Glacigenic mass-wasting has been studied by SeaMARC II sidescan sonar/bathymetric swathmapping system towed by research vessel in October--November 1989 and September--October 1990. Glacigenic formation under fan is thought to consist of thick accumulations of sediment, rapidly deposited during relatively short periods when Barents ice shelf approached shelf edge, separated by longer intervals when fan was sediment-starved (as in Holocene) and accumulated only hemipelagic materials at 1 to 10 cm ka⁻¹. Has been speculated that glacigenic formation under fan comprises packets of mudflows, each packet representing one of about half-a-dozen ice-sheet advances to shelf edge in last 900 ka.
