Cruise summary report

Cruise Info. 
Ship name (ship code)RRS Discovery (74E3)
Cruise identifierD214
Cruise period1995-02-26 — 1995-03-09
StatusCompleted
Port of departureDurban, South Africa
Port of returnCape Town, South Africa
PurposeResearch
ObjectivesThe 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.
