3.4.2.2.2. Sea surface temperature

Distribution of monthly day and night sea surface temperature SST in 2010–2011 at Pangumbahan beach and adjacent coasts were obtained from Aqua Modis satellite images level-3 with 4x4 km resolution. These image data were available in National Aeronautic Space Agency NASA website http:www.oceancolor.gsfc.nasa.gov. The raw image data then cropped and extracted into .ascii data format with Seadas 5.2.0. program. The .ascii data were copied into Microsoft Excel 2007 spreadsheets to be furthermore to be saved into .txt data format and visualized them in Ocean Data View ODV 4 program. Population and nest temperature data were compiled and processed in Microsoft Excel 2007 and Statistica 6.0 program. Statistical significance tests were done by using XLstat program.
