Summary: | discuss the design and implementation of an observational system to monitor the South Atlantic’s branch of the Meridional Overturning Circulation (SAMOC). The workshop was financially supported by the NOAA Climate Program Office and US CLIVAR. After reviewing and discussing existing modeling and observational efforts in the South Atlantic Ocean it was concluded that they are inadequate to monitor the MOC and ensuing discussions were focused on the design of an observational array that was adequate for this purpose. Plans were established to coordinate modeling efforts, and existing and future observations in the Drake Passage, in the region between South Africa and Antarctica, and on a zonal transect nominally across 30˚S. The main recommendations from the workshop can be summarized as follows: 1. Modeling results indicate the need to increase observations not only in the choke points but also in the interior of the South Atlantic, where water mass transformations occur and large discrepancies exist between different models and between models and observations. Therefore, it is imperative to sustain and expand the existing basin wide observations (i.e. Argo, surface drifters, high density XBT programs) and satellite altimetric missions with sufficient spatial and temporal resolution to resolve mesoscale features. The group also endorsed collaboration with |
