January 16 2012 Pacific Islands Regional Climate Assessment (PIRCA), Honolulu, Hawaii, LONG TERM SEA SURFACE TEMPERATURES TRENDS IN US AFFILIATED PACIFIC ISLANDS FROM SATELLITE DATA, 1982-2003
Thomas J. Goreau, PhD Monthly average NOAA satellite-derived Sea Surface Temperature (SST) values from 1982-2003 and their long term trends are presented for sixteen US affiliated Pacific Islands: Midway, Johnson, Maui, Tutuila, Bikini, Enewetak, Kwajalein, Majuro, Kapingamarangi, Kosrae, Pohnpei, Chuuk, Yap, Palau, Guam, Saipan, and Palmyra from the Global Coral Reef Alliance Long Term Global Coral Reef Sea Surface Temperature Database. These data were compiled from NOAA data and are part of a worldwide database covering every major reef area of the world. All sites show clear upward trends in mean temperature but these differ from place to place due to regional trends in ocean circulation. Also very noticeable is a strong cooling event in 1982, especially in some northern Hemisphere sites, cause by stratospheric aerosol plume from the eruption of the El Chichon volcano, and a much smaller one at some sites from the Pinatubo eruption in 1991. The upward trends at all sites remain when those years and when El Nino years are removed from the data (for more details see references). The raw data trend equations are shown on each graph where x is time in months. For much more information on methods, results, and analysis see: 1. T. J. Goreau, R. L. Hayes, J. W. Clark, D. J.
