Abstract: An intense bloom of Tetraselmis sp., producing strong water discoloration was observed from December 28th of 2005 through January 10th of 2006 in the Valparaiso Bay (32º 57’S; 71º 33’W). Blooms of Tetraselmis sp. have never been reported in this bay, or along the coast of Chile. The confluence of a series of environmental conditions observed before and during the bloom such as: high solar radiation, anomalous UV radiation levels, high sea surface temperatures, water stratification and high nutrient concentrations may have contributed to the development of this unique event.
