The Ocean Reference Station at 20 degs S, 85 degs W under the stratus clouds west of northern Chile is being maintained to provide ongoing climate-quality records of surface meteorology air-sea fluxes of heat, freshwater, and momentum, and of upper ocean temperature, salinity, and velocity variability. The Stratus Ocean Reference Station ORS Stratus is supported by the National Oceanic and Atmospheric Administrations NOAA Climate Observation Program. It is recovered and redeployed annually, with cruises between October and December. During the October 2007 cruise on the NOAA ship Ronald H. Brown to the ORS Stratus site, the primary activities were recovery of the Stratus 7 WHOI surface mooring that had been deployed in October 2006, deployment of a new Stratus 8 WHOI surface mooring at that site in-situ calibration of the buoy meteorological sensors by comparison with instrumentation put on board the ship by staff of the NOAA Earth System Research Laboratory ESRL and observations of the stratus clouds and lower atmosphere by NOAA ESRL. Meteorological sensors on a buoy for the Pacific tsunami warning system were also serviced, in collaboration with the Hydrographic and Oceanographic Service of the Chilean Navy SHOA. The DART Deep-Ocean Assessment and Reporting of Tsunami carries IMET sensors and subsurface oceanographic instruments. A new DART II buoy was deployed north of the STRATUS buoy, by personnel from the National Data Buoy Center NDBC Argo floats and drifters were launched, and CTD casts carried out during the cruise.
