BODC Cruise Metadata Report for RRS Discovery (74E3) cruise D214

Introduction

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

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D214
Short name D214
Objectives and Narrative The primary objective of the cruise was to deploy an array of moored current meters.
The second objective of the cruise was to make a hydrographic section of the Agulhas Current in order to determine the geostrophic transport of the Current.
In addition, for this cruise, two developmental acoustic profiling techniques were prepared to help define the velocity structure of the Agulhas Current.
