The Second SAMOC Workshop took place in Paris France, July 1 and 2, 2009.
The main objective of the workshop were:
• Review the main achievements made since May 2007
• Review and update current collaborations
• Further coordinate the efforts with the Southern Ocean Observing System community and the paleo community.
• To agree and design a poster to be presented at OceanObs’09
• To review the South Atlantic component of the AMOC White paper for OceanObs’09.

The first day of the meeting consisted in presentations detailing new advances in science and in observations in the South Atlantic. The importance of monitoring the South Atlantic was emphasized based on modeling results that demonstrated:1) the SA, the sole generator of the compensating flows for the southward flowing NADW, is not a passive ocean. Water mass transformations occurred in the regions of high variability, i.e., the Confluence and the Cape Basin. Therefore observations of the AMOC are need in the Subtropical South Atlantic. 2) The variability in those regions is highly correlated to the variability of the winds in the South Pacific and Indian Oceans. Therefore, in order to understand the origins of this variability, observations in the SA should be related to observations or modeling results in the adjacent basins. The main discussion was focused on what parameters are needed to be measured and what were the best locations to observe them.
It was agreed to have the next meeting in Brazil, May-June 2010.

The SAMOC group already started with ongoing collaborative projects that include :
1) the undertaking of proof-of-concept numerical studies to design a monitoring system capable of determining the time-variable overturning in the South Atlantic and its horizontal fluxes of heat/
2) a number of coordinated observing efforts such as the GoodHope international effort and the already deployed arrays of C-PIES and PIES along the high resolution NOAA-AOML XBT AX18 zonal line (see figure here below for a summary of ongoing/planned observations).
