Parr (1939) estimated an average biomass of Sargassum as approximately 1 g.m-2 wet weight in the 1930s for the Sargasso Sea. The South Atlantic Fishery Management Council (2002) estimated 0.8 to 2 g.m-2. The present satellite observations suggest concentrations an order of magnitude greater (25 g.m-2) in the western Gulf of Mexico. ................
