Tsunami Warning Buoy Deployed off Chile


January 1, 2005

Scientists from the Chilean Navy Hydrographic and Oceanographic Office (SHOA),
in cooperation with the Woods Hole Oceanographic Institution (WHOI), deployed a
SHOA tsunami warning buoy off Northern Chile in the Pacific in December 2004
just prior to the devastating Indian Ocean tsunami. The mooring is part of a
Chilean national plan for a comprehensive ocean array west of Chile. The tsunami
deployment buoy was one of many NOAA-funded activities undertaken under the
direction of a WHOI Chief Scientist from the vessel Ronald H. Brown,
which sailed from Arica, Chile, December 5 with the primary mission of
recovering and redeploying the NOAA Climate Observation program.s Ocean
Reference Station (ORS) at 85°W, 20°S under persistent stratus clouds found off
northern Chile and Peru. The WHOI Upper Ocean Processes Group maintains this
station as well as one north of Hawaii and another near Barbados in the North
Atlantic. The high quality data collected at the ORS are used to produce
accurate estimates of the air-sea exchanges of heat, freshwater, and momentum
and to validate and motivate improvement in numerical atmosphere, ocean, and
coupled models. As in earlier cruises to the stratus region, scientists from
NOAA.s Environmental Technology Laboratory in Boulder, CO and Chilean university
investigators and graduate students participated in research activities, as did
a middle school teacher from Arkansas chosen as the NOAA teacher at sea for this
cruise.
