A16N-2013

CLIVAR/GO-SHIP cruise A16S_2014 in the South Atlantic on NOAA ship Ronald H. Brown was successfully completed over two legs: Leg 1: (3 August to 23 August 2013) and Leg 2:(1 September to 3 October 2013). Leg 1 of the A16N_2013 cruise began in Reykjavik, Iceland and ended in Funchal, Portugal. Leg 2 of the A16N_2013 cruise began in Funchal, Portugal and ended in Natal, Brazil. The A16N_2013 cruise ran from approximately 66°N to 6°S, repeating the section previously occupied by the US in 1988 and 2003. A total of 145 full water column CTD/02/LADCP/rosette casts were completed along the A16N_2013 section at ~30 nautical mile (nm) spacing, with closer spacing near boundaries and between 3°N and 3°S. A 24 position rosette was used for the hydrocasts. Separate casts for trace metal analysis were occupied at approximately 60 nm spacing, using a specially designed 12 position trace metal clean winch and rosette system. In addition, 16 Argo floats and 10 surface drifters were deployed.
