GOES-13 (GOES-East) Sounder instrument is experiencing an anomaly. GOES-13 Sounder IR data is not available. All products from GOES-13 (GOES-East) Sounder IR data have been halted and distribution has been stopped. Engineers are investigating the problem.
NOAA/NESDIS oceanographer, Dr. Al Strong, has collected reports of coral bleaching from an informal network of coral reef researchers and observers. These reports have been overlayed on the following 1998 animations and images.
Each asterisk symbolizes a new bleaching report and remains on the animation/image for four weeks.
The Animation of the Great Barrier Reef Bleaching Event, (El Nino, 1/17/98-4/17/98, 1.6 mb) depicts hotspots in the Indian Ocean intensifying east of Australia, east of Madagascar, and south of Africa, with bleaching reports noted in the Great Barrier Reef. The hotspots then dissipate somewhat and move northward towards India.
The Animation of the Indian Ocean Bleaching Event, (El Nino/La Nina transition period, 3/24/98-7/24/98, 1.0 mb) depicts hotspots from Africa to west of Indonesia and Australia moving northwards towards India, with coral bleaching reports scattered throughout the Indian Ocean.
The Animation of Bahrain, Red Sea and Eastern Pacific Bleaching Events, (early La Nina, 7/4/98-10/27/98, 0.8 mb) shows hotspots in Southeast Asia, with intense hotspots in the Red, Caspian, Black, Arabian, and Mediterranean Seas and east of Japan.
The Animation of the Western Hemisphere Bleaching Events, (early La Nina, 6/20/98-11/7/98, 1.1 mb) depicts hotspots near Panama and Colombia, followed by development of a large area of hotspots from the Atlantic to the Baja peninsula, with bleaching reports clustered in the Caribbean. The pattern then breaks up and shifts south between South America and northwest of Africa.
The Animation of HotSpots during El Nino, (1/3/98-6/6/98 in the Western Hemisphere, 2.0 mb) shows the classic pattern of an extensive region of hotspots reaching from the coasts of Colombia, Ecuador, and Peru out into the Pacific Ocean.
The Indian Ocean Bleaching Event - time series , (3/24/98-8/11/98) is a series of five images showing hotspots extending the entire length of the Indian Ocean from Africa to Indonesia, with hotspots decreasing in intensity over time.
The Western Hemisphere Bleaching Event - time series, (6/20/98-9/8/98) is a series of six images showing hotspots initially focused off the coast of Colombia and the Pacific side of lower Central America. Later hotspots are located east of Florida and in the Caribbean. Most of the reports indicate bleaching around Florida and Cuba.
