First observations on phytoplankton and chlorophyll ecology in the coast of Hadhramout, Gulf of Aden


Author(s): Ali Attaala Mukhaysin, Bazar Salem Rubae

Abstract: Data were collected from 5 sites at Hadhramout coast between October 2009 and January 2011 once a month; the characterization of these sites is based on phytoplankton biomass, enumeration and chlorophyll a measurements. The chlorophyll a pattern was found to have significant local and seasonal variations within the coast with a values ranging from 0.08 mg/m3 in April at Mukalla area to 15.2 mg/m3 in Sep. at BirAli area. Naturally this is a result of strongly changed phytoplankton mass level during the year. The seasonal dynamic character of phytoplankton characterized by summer raising that observed in May and July, with a clear excess in Broome and BirAli areas. Least phytoplankton content was observed in November in the Broome and Mukalla stations. 240 phytoplankton species were identified, in which Diatoms and Dinoflagellates were dominant taxonomic categories in abundance. Phytoplankton mass along the coast illustrates general decreasing from BirAli station in the west to Sharma in the east of Hadhramout coast.
