The mechanism of thermocline ventilation is investigated using a global, high-resolution ocean GCM, with realistic topography and surface wind forcing. Because 2-dimensional representations of circulation can be misleading, the subsurface flow is examined by visualizing the trajectories of particles which subduct in the mid-latitudes and travel within the ventilated thermocline.

The Coherent Launch Site Atmospheric Wind Sounder (CLAWS) is a test and demonstration program to investigate the feasibility of using a solid-state coherent lidar to obtain wind data from the surface to 20 km or more altitude in real time for launch site vehicle guidance and control (G&C) applications.1 This paper discusses the design and tests of a 1-J coherent lidar.
