BODC Cruise Metadata Report for RRS Discovery (74E3) cruise D164

Introduction

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

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D164
Short name D164
Objectives and Narrative 1. To document the incidence and nature of frontal structures in the Southern Ocean.
2. To document downstream variations in the structure of the Antarctic Circumpolar Current.
3. To estimate the transport of the ACC.
4. To observe spatial variations in the T/S properties of mode waters and compare the observations with theories of mode water formation.
5. To explore the potential of the SeaSoar and Acoustic Doppler Profiler to quantify the scales and meridional transport of mesoscale eddies in the Subantarctic Zone.
