Dataset: Long-term mean daily seawater temperature data from USVI starting in 2003.

These data have been utilized for several publications analyzing different aspects of seawater temperature, including Edmunds: Royal Society 2006, Green et al: Journal of Experimental Marine Biology and Ecology 2010, Green and Edmunds: Journal of Experimental Marine Biology and Ecology 2011, and Edmunds: Marine Ecology Project Series 2013. Temperatures were averaged by day and month and used to calculate annual mean and range using monthly mean temperatures. Daily temperatures were used to categorize days as hot (> 29.3°C) or cold (≤ 26.0°C), with hot days exceeding the coral bleaching threshold for St. John (http://coralreefwatch.noaa.gov/satellite), and ‘cold days’ less than or equal to the lower 12th percentile of daily seawater temperatures in Great Lameshur Bay between 1989-2005 (Edmunds 2006).This dataset cotains data annually updated data ongoing since July 1999.
