Observations

An expedition to the Weddell Sea aboard the R.V. Nathaniel B. Palmer will take place in the late Antartic Winter of 2005 (see Figures 1 and 2). The goals of the expedition are to survey the area around Maud Rise looking for conditions favorable for overturning convection and to conduct a detailed process study of the role of nonlinearities in the equation of state in promoting convection (Figure 3).
