PurposeResearch
Objectives1. To recover the NEADS-6 upper bottom c/m mooring at 52° 30' N 17° 45' W and replace it with a full depth mooring.
2. To recover the seven upper bottom c/m moorings deployed along 41° N during CIROLANA 6/78.
3. To lay a further seven upper bottom c/m moorings at positions between the NEA low level waste dumpsite and the European continental slope.
4. To conduct hydrochemical sampling and TSD calibration in the vicinity of the NEA dumpsite (around 46° N 17° W).
5. To conduct an XBT and/or STD reconnaissance of an eddy over the Biscay Abyssal Plain (location to be determined).
6. To sample bottom living fish and other species in the NEA dumpsite using traps and hooks.
