Description 
Summary

RRS Discovery cruise 199 was a UK contribution to the World Ocean Circulation Experiment (WOCE) one time survey, its designation A11. The cruise ports were Punta Arenas, Chile to Cape Town, South Africa. 91 full depth stations were worked with a NBIS Mk3b CTD and GO 24x10 litre rosette water sampler. Salinity, oxygen, silicate, nitrate and phosphate were measured on each station, CFC-11, CFC-12, and CFC-13 were measured on every other station and XBT drops (mostly T7) made between stations. Meteorological parameters, sea-surface temperature and salinity, and current profiles to 300m (from a hull-mounted RDI 150kHz ADCP) were measured throughout the cruise. To improve estimates of the ship's heading (and hence currents) a three-dimensional gps receiver from Ashtech was employed.
