Title:
Summer 2004 Coral Bleaching Event on Tutuila, American Samoa (NODC Accession 0001955)
Abstract:
American Samoa's coral reefs have been impacted by a variety of major events, including periodic severe hurricanes, the most recent of which was Hurricane Heta, which was closest on Jan 6, 2004. Other events have included a Crown-of-Thorns seastar outbreak in 1974 and night scuba spearfishing from 1994-2002. Mass coral bleaching occurred in 1994 and then again in the summers of 2002 and 2003, and the bleaching was severe enough to kill some corals. Bi-weekly surveys were made of the reefs at Airport Lagoon. During the peak of the summer bleaching, surveys were made at five other locations. The data given with this data set refer to the percent corals bleached within the survey area.

  2. How were the data generated, processed, and modified?

    Date: Unknown (process 1 of 1)
    The percentage of bleached colonies was estimated visually and mentally following a roughly one-hour swim in the lagoon along roughly the same path. The swimming rate was steady and moderate for a SCUBA diver wearing fins. This method results in course resolution. Accuracy subjectly estimated at 10-20%. Craig, P., Birkeland C, Belliveau S. 2001.
