  • Nov 2016: SAMOC was featured in Issue 26 (page 9) of the Partnership for Observation of the Global Oceans (POGO) newsletter.
  • Aug 2016: Several SAMOC-related postdoctoral positions at the University of Miami are now open. Successful candidates will work with researchers in the Physical Oceanography Division (PhOD) of NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Florida. These open postdoctoral positions will focus on 1) Argo analysis of oceanic variability, 2) Atlantic MOC observations, 3) South Atlantic MOC variability, 4) southward returning pathways of the AMOC, and 5) inter-ocean exchanges in the South Atlantic and their link to global monsoons. More details about these postdoctoral positions can be found at the bottom of the NOAA/AOML/PhOD webpage. Additionally, these postdoctoral opportunities can be found by searching on the University of Miami employment webpage for the following position numbers (P100015908, P100015909, P100015913, P100015914).

  • Mar 2016: A recent paper published in the Journal of Climate by Hosmay Lopez, Shenfu Dong, Sang-Ki Lee, and Gustavo Goni provides a physical mechanism on how low frequency variability of the South Atlantic Meridional Heat Transport (SAMHT) associated with the Atlantic Meridional Overturning Circulation (AMOC) may influence decadal variability of atmospheric circulation and monsoons. This is the first attempt to link the South Atlantic Overturning Circulation variability to weather and climate. For more details, visit this link.
  • Mar 2016: Sabrina Speich is conducting a cross-basin, lower atmosphere/upper ocean physical and biogeochemical survey aboard the Meteor, a German research vessel, in the South Atlantic. The South Atlantic is a key region in the context of the global thermohaline circulation where exchange between Indian, Southern, Pacific and the Atlantic Oceans takes place. The survey during M124 aims to: estimate the upper ocean meridional heat and freshwater transport along approximately 30S, the physical/biogeochemical characteristics of Agulhas Rings, transporting Indian Ocean Water far into the South Atlantic; aerosols, surface radiation balance, and precipitation measurements; the surface water carbonate system parameters (pCO2). The expedition will also be used for training purposes, in particular students from South Atlantic bordering countries will participate and will use the data to perform their own investigations related to the scientific objectives of the cruise. For more details about this cruise, please visit the cruise webpage and the blog by cruise participants.
