Cruise identifierCIR11/96
Cruise period1996-12-02 — 1996-12-22
StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
PurposeResearch
ObjectivesOne of a series of cruises to study:
1) The properties of real dredged material at two key sites (Harwich Tower and Tees Bay.
2) Environmental monitoring and research relating to the distribution and behaviour of radionuclides in the water column and sediments of UK waters.
Main tasks:
A) To deploy instruments, obtain core samples and carry out side scan surveys in two locations (Harwich Tower and Tees Bay).
B) To collect and process surface/bottom seawater and sediments for the analysis of TC-99 and transuranic radionuclides, as part of post-EARP surveys.
C) To collect and process surface water for analysis of SS and tritium for the biennial monitoring programme.
