Purpose

Research

Objectives

1. To map the density field on a fine grid approx 50km x 40km centred on the OSCR measurement area; three separate surveys covering the neaps-springs cycle were needed to initialise and test numerical models of the flow.
2. To determine the vertical structure of the longshore and cross-shore velocity field on the principal section of OSCR area using the ADCP over two separate 25 hour periods.
3. To undertake an initial trial of a cluster of Argos-Decca buoys with the intention of providing data on near-surface currents to validate the OSCR measurements and to test the flexibility of the experimental design for dispersion experiments planned for cruise 36 (Hill et al).
4. To provide sea surface data for an aerial survey of the frontal zone by the Daedius scanner mounted on the NERC aircraft. Sea level measurements were to include irradiance meter measurements of reflection together with water samples for pigment and seston determination.
In addition to these primary goals, we also aimed to make some measurements of the T-S structure off Flamborough Head both as a reconnaissance exercise for cruise 36 and to investigate the possible occurrence of filament structures with a scale of 10km which have been observed in satellite I-R images of the area.
