Ship name (ship code)RRS Charles Darwin (74AB)
Cruise identifierCD179
Cruise period2006-04-14 — 2006-05-17
StatusCompleted
Port of departureCartagena, Spain
Port of returnFalmouth, United Kingdom
ObjectivesOne of a series of cruises studying the biology, geology, biochemistry and physical oceanography of Portuguese Margin canyon systems as part of the EU Integrated Project HERMES (Hotspot Ecosystem Research on the Margins of European Seas).

The cruise was in two legs with a mid-cruise port call in Lisbon on 1 May 2006. Leg 1 focussed on the upper and middle parts of the Lisbon and Setúbal Canyons, which join together at a depth of about 2000m, and the upper and middle Cascais Canyon. Leg 2 sampled the lower Cascais and Setúbal Canyons, and a wide variety of depths in the Nazaré Canyon
