The third time was the charm for WHOI researchers and their Chilean partners to replace an instrument-rich surface mooring in the eastern tropical Pacific, 976 nautical miles east of Valparaiso. Two earlier attempts to deploy a new Stratus Ocean Reference Station to collect atmospheric and oceanographic data had been scrubbed. The Stratus 19 deployment continues a more than 20-year ongoing presence of a buoy in the otherwise data sparse area. Researchers use the data to calibrate climate models which otherwise can include inaccurate sea surface temperature measurements for the region. The National Oceanic and Atmospheric Administration, which supports the ORS mission, pays for WHOI’s use of the Cabo de Hornos.
