| Objectives | 1. To recover and relay the NEADS-6 upper-bottom c/m mooring at 52 degrees 30' north 17 degrees 45' west, deployed during CIROLANA 11/77.
2. To recover the three upper bottom c/m moorings deployed in the Gibbs Fracture Zone during CIROLANA 11/77. 3. To lay an east-west network of upper bottom c/m moorings north east of the Azores between the mid-Atlantic Ridge and the NEADS-4 site at 41 degrees north 25 degrees west. 4. To test the MK II neutrally buoyant float tracking system at the above site. 5. To make XBT observations every 15-20 miles on passage with emphasis on the mid-Atlantic Ridge crestline and the continental slope of the eastern North Atlantic. 6.
