Bedforms and the Benthic Boundary Layer in the North Atlantic: A Cruise Report of INDOMED Leg 11.

In August and September 1978, deep-tow surveys were conducted with R/V Melville at four sites in the North Atlantic: a field of mud waves on the Moroccan continental rise; a patch of hyperbolae-creating bedforms with interfingering debris flows on the Saharan continental rise; an area of abyssal fur...

Description
Summary:In August and September 1978, deep-tow surveys were conducted with R/V Melville at four sites in the North Atlantic: a field of mud waves on the Moroccan continental rise; a patch of hyperbolae-creating bedforms with interfingering debris flows on the Saharan continental rise; an area of abyssal furrows near the crest of Eastward Scarp on the Bermuda Rise; and a field of furrowed sediment waves on the southwest Bermuda Rise. In addition to near-bottom acoustic records, the deep-tow instrument collected stereo photos, CTD and nephelometer data, and samples of bottom water and suspended sediment. There were also current meter, hydrocast and coring stations. This report includes preliminary deep-tow maps of each site, locating photo runs and samples, and presents a few typical sections of data. (Author)
