SEDIMENT TRANSPORT OVER THE HATTON AND GARDAR CONTOURITE DRIFTS uri icon

abstract

  • Gardar Drift is made of muddy contourites deposited from Iceland-Scotland Overflow Water with a thick and relatively intense nepheloid layer whose particles originate from Iceland. Hatton Drift is also mainly mud, possibly from Rockall Bank, but at its foot a strong NE-flowing boundary current moves winnowed foraminiferal sand as ripples and low sand waves. The nepheloid layer on Hatton Drift is locally generated and is mainly in a stratum of N Atlantic Deep Water that is contaminated with AABW. This stratum, with its entrained particles, spreads across the basin as far as the crest of Gardar Drift. -from AuthorsSchool of Environmental Sciences, Univ. of East Anglia, Norwich UK. English
