BODC Cruise Metadata Report for RV Corystes (74RY) cruise COR8/02

Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RV Corystes (74RY) cruise COR8/02
Short name COR8/02
Objectives and Narrative The work was directed toward:
a) a better understanding of the circulation processes of the southern and central North Sea in order to characterise the transport of nutrients from UK waters;
b) improved knowledge of the processes that determine areas of strong phytoplankton production in the vicinity of the Frisian Front.

The main sampling aims of the cruise were:
1) Deploy free-floating satellite tracked buoys in order to determine the Lagrangian circulation. Subsequently, a number may be retrieved.
2) To undertake Scanfish and CTD surveys to collect information on the water column structure in relation to nutrient and plankton dynamics.
3) Conduct productivity experiments and assess nutrient uptake.
