Cruise Inventory Information
| Long name | RRS Charles Darwin (74AB) cruise CD179 |
|---|---|
| Short name | CD179 |
| Objectives and Narrative |
One 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 |
