  • Highlight #1:
    South Atlantic Workshop and SAMOC V Meeting in Buenos Aires, Argentina, Dec 1-5, 2014
  • The main objective of this workshop was to bring together theoreticians, modelers and observationalists interested in the South Atlantic Ocean region and its interactions with other ocean basins. The Workshop included a strong training component for students and young researchers. Participants had the opportunity to interact and discuss with experts from the international South Atlantic Meridional Overturning Circulation (SAMOC) community and other guest specialists interested in the basin circulation and its effects on global circulation and climate. The workshop conveyed state-of-the-science knowledge and understanding of the subject, allowing participants to improve their research and to strengthen and develop new professional links. The SAMOC V Workshop conducted in days 4 and 5 was aimed at communicating preliminary results from the SAMOC observations and models, to compare these results with estimates of the MOC fluxes at other locations in the Atlantic and elsewhere, and to discuss ongoing and planned observations and modeling activities. The Workshop received financial support from the Abdus Salam International Center for Theoretical Physics, NOAA Climate Program Office, the US Clivar office, the Inter-American Institute for Global Change Research, Montevideo, Uruguay, and Consejo Nacional de Investigaciones Cientificas y Tecnicas. The event was attended by participants from Argentina, Brazil, France, Germany, Italy, Peru, Uruguay, the United Kingdom, and the United States.

  • Highlight #2:
    SAMOC-9 Cruise,
    Oct 4-16, 2014
  • The Argentine research vessel Puerto Deseado just completed the ninth joint USA-Argentina-Brazil cruise in support of SAMOC and the Southwest Atlantic MOC ("SAM") project along 34.5S. Participants in the cruise included researchers from the Universidade de Buenos Aires (UBA), the Servicio de Hidrografia Naval (SHN), the Instituto Nacional de Investigacion y Desarrollo Pesquero (INIDEP), the Universidade Federal do Rio Grande (FURG), and the Universidade de Sao Paulo (USP), as well as NOAA-AOML. On this Puerto Deseado cruise, the scientists collected temperature, salinity, and dissolved oxygen profiles and acoustically downloaded data from four pressure-equipped inverted echo sounders (PIES) moorings in the SAM array, as well as two similar Brazilian instruments.
