Colvocoresses Reef
In the article Colvocoresses Reef, you write that the reef is named after Dr. Alden Partridge Colvocoresses. Please provide references to this statement.

According to http://mitglied.lycos.de/dc3mf/Blenheim.htm the reef is named after the Portugese vessel 'Colvocoresse', which ran aground on the reef in January of 1790.

I would like to determine which information is correct.Ratzer 20:26, 13 September 2006 (UTC)

Reply: The reef was named after by Dr. Colvocoresses by the Defense Mapping Agency's Geographic Board of Names shortly after it's discovery on the Landsat MSS images. As I was the discoverer, I was the one to nominate that the reef be named after Dr Colvocoresses. This was formalized in September 1976 with the publishing of Nautical Chart 61610 (Third Edition) showing the recently discovered reef as well as correctly repositioning a number of other islands and reefs in the Chagos area, some of which had been shown up to 18 km from their true position. This is documented in the paper: "Landsat Goes to Sea" by Hammack J. presented at the Second Annual William T. Pecora Memorial Symposium in Sioux Falls, S. D., [Oct. 25-29, 1976]. It was also published in the Journal of the American Society of Photogrammetry and Remote Sensing in June 1977 ("Landsat Goes To Sea" by Hammack J.
