Between 1985 and 1994, an extensive array of moored and drifting buoys was deployed across the equatorial Pacific Ocean to monitor and help predict the El Niño phenomenon.[10] Hurricane Katrina capsized a 10 m (33 ft) buoy for the first time in the history of the National Data Buoy Center (NDBC) on August 28, 2005.[11] On June 13, 2006, drifting buoy 26028 ended its long-term data collection of sea surface temperature after transmitting for 10 years, 4 months, and 16 days, which is the longest known data collection time for any drifting buoy.[12] The first weather buoy in the Southern Ocean was deployed by the Integrated Marine Observing System (IMOS) on March 17, 2010.[13]
