(2) To recover NEADS 5.
(3) To recover and re-lay four upper-bottom moorings deployed by CIR06/81 east of the mid-Atlantic Ridge. Accomplished.
(4) To lay six moorings across the Madeira Abyssal Plain at 30 N. Accomplshed.
(5) Deploy abyssal fish traps. Accomplished. Catch included Coryphanoides and amphipods.
(6) Recover moorings deployed by CIR9/80 in the King's Trough area. Three of four moorings recovered.
(7) Collect large-volume water samples for radiochemical analysis. Accomplished.
(8) CTD profiling and nutrient sampling. Accomplished.
(9) Regular deployment of XBTs across appropriate parts of the cruise track. Accomplished.
(10) Investigate CTD lowering rate on conductivity measurements in near-surface water. Accomplished.
(11) Take box, boomerang and gravity cores accompanied by near-bed water samples. Accomplished.
(12) Collect surface water samples for neodymium analysis. Accomplished.
(13) Run an on-line HIAC particle sampler section across the continental slope. Accomplished.
