Date: 1975Title/Ch.: Mortality of marine organisms associated with offshore summer blooms of thetoxic dinoflagellate Gonyaulax monilata Howell at Galveston, TexasBook: Proceedings of the First International Conference on Toxic DinoflagellateBloomsEditor: V. R. LoCiceroPages: 257-263Publisher: The Massachusetts Science and Technology Foundation, Wakefield, MAKey words: mortality, bloom, dinoflagellate, Gonyaulax monilata, Galveston, Texas, snail,hermit crab, brittle star, red tideSummary: The authors document two red tides of the toxic dinoflagellate Gonyaulaxmonilata [preferred name Alexandrium monilata] that occurred in waters nearGalveston, Texas in the summers of 1971 and 1972, with recorded maximum celldensities of 1.2 x 10 6 cells/L and 1.88 x 10 6 cells/L, respectively. Twenty-ninespecies of cnidarians, annelids, molluscs, crustaceans, echinoderms and fishes, allsedentary or slow-moving, were represented among the organisms that perishedfrom the toxin. Monitoring in the summers of 1973 and 1974 did not detect thepresence of G. monilata, perhaps due to lower salinities (
Date: 1993Title/Ch.: The nutrient and hydrographic conditions prevailing in Laguna Madre, Texasbefore and during a brown tide bloomBook: Toxic Phytoplankton Blooms in the SeaEditor: T. J. Smayda and Y. ShimizuPages: 711-716Publisher: Elsevier Science Publishers B. V.Key words: nutrients, Laguna Madre, Texas, brown tide, bloom, pigment, chrysophyte, BaffinBay, dissolved inorganic nitrogen, ammoniumSummary: An unidentified aberrant chrysophyte bloomed widely for more than 18 months inthe hypersaline Laguna Madre. The bloom followed dissolved inorganic nitrogen(DIN) concentrations of almost 20 µmol/l, especially in Baffin Bay, withammonium composing 60-95% of the DIN. Baffin Bay, subject to annual salinityvariations of as much as 65 ppt, also had the greatest salinity of the north to southgradient in the Laguna Madre, ranging from 40-60 ppt during the bloom.Methods: See “Methods.”QA/QC: None per se; see “Methods.”Contact: Terry E.
