RV Corystes COR3B/89
Cruise summary report
Cruise Info. | |
Ship name (ship code) | RV Corystes (74RY) |
Cruise identifier | COR3B/89 |
Cruise period | 1989-03-06 — 1989-03-20 |
Status | Completed |
Port of departure | Workington, United Kingdom |
Port of return | Immingham, United Kingdom |
Purpose | Research |
Objectives | 1. To investigate the effects of tidally-induced resuspension of sediment on the scavenging of dissolved radionuclides in the north-east Irish Sea. Two anchor stations will be occupied, for at least 13 hours, and in both cases the NBVR will be deployed nearby. ACB4/6
2. To examine the nature and rates of chemical processes in the sea bed using Ra-226, ultra-filtration, incubation experiments, fine resolution sampling and selective leaching. ACB3/4/8 3. To determine temporal trends in the biological characterisation of representative sites. ACB1 4. To measure the concentration of Ra-226 in sea water off Whitehaven and Maryport in relation to local anthropogenic sources. ACB4 5. To collect water and sediment samples for C-14 analysis at SURRC, East Kilbride in support of a NERC/MAFF CASE studentship. ACB10 6. To examine further the distribution and inventory of transuranic and gamma-emitting radionuclides in seabed sediments at selected sites following improvements in the Kasten corer. ACB2 7. To make a deliberate tracer release (sulphur bexafluoride and helium-3) in surface waters off the Netherlands coast, in conjunction with RRS Challenger and PML scientists, to examine dispersion and venting to the atmosphere. |
