PurposeResearch
ObjectivesThe scientific objectives of the cruise, undertaken as part of the NERC North Sea Project, were to investigate gross and net primary production during bloom conditions and to examine the relationships between primary productivity and the biogeochemical cycling of certain trace metals and biogenic trace gases. In order to be able to relate changes in water chemistry to primary productivity it was intended to make time series measurements of chemical, biological and hydrographic parameters within a tracked body of water in which production was occurring. Measurements on transects were also to be made (1) to enable the characteristics of the tracked water body to be related to those of the surrounding waters, and (2) to enable comparisons to be made of biological and chemical characteristics of waters within contrasting productivity regimes, affording additional information and an alternative strategy should the required changes in biological activity not occur during the time series experiments.
