|Cruise identifier||4/82 PT2|
|Cruise period||1982-04-23 — 1982-05-03|
|Port of departure||Aberdeen, United Kingdom|
|Port of return||Aberdeen, United Kingdom|
|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.
