ObjectivesThe aims of this cruise were:
(1) Recover 8-mooring array on the SW Approaches continental slope. Four recovered, but four lost.
(2) Recover the NEADS-6 mooring from 52.5N, 17.75W. Accomplished.
(3) Survey midwater nepheloid layers along the Porcupine Bank Slope using CTD, nephelometer, transmissometer and HIAC. Accomplished.
(4) Lay and recover a short-term mooring of thermistors and current meters on a site of slope erosion on the Porcupine Bank. Deployed for three days.
(5) Establish a working shipboard system for bulk radiochemical sampling. Accomplished.
(6) Lay bottom current meter moorings to the SW of Rockall Bank and east of the mid-Atlantic Ridge. Four moorings deployed to be recovered on CIR9/81.
(7) Deploy abyssal fish traps. Four deployments yielding 7 Coryphanoides and a few amphipods.
(8) Make continuous surface chlorophyll and nutrient measurements. Accomplished.
(9) Sample mackerel post-larvae using a neuston net. Accomplished.
(10) Recover the Nab Tower current meter mooring. Accomplished.
(11) Take regular XBT profiles whilst underway. Accomplished.
(12) Take surface samples for radiocaesium analysis. Accomplished.
