Cruise period | 1982-04-23 — 1982-05-03 |
Status | Completed |
Port of departure | Aberdeen, United Kingdom |
Port of return | Aberdeen, United Kingdom |
Purpose | Research |
Objectives | 1. To obtain and analyse samples for total soluble and particulate nitrogen from a number of sections in the central and northern North Sea.
2. To work standard hydrographic/chemistry/plankton stations on the same sections. 3. To study the depth distribution of the zooplankton standing stock using a Longhurst-Hardy Plankton Recorder. 4. To test plankton gear instrumentation. 5. To collect water at 56 32'N 2 20'W for radio-caesium monitoring. 6. To collect plankton from a number of areas for heavy metal analysis. With the exception of the zooplankton depth distribution samples, all samples were obtained successfully. |
