(1) The paper reports results of laboratory studies on growth rates at elevated temperatures of two diatoms (Chaetoceros wighami and Amphora coffeaeformis) isolated from the intake and outfall sites of a coastal power station on the east coast of India. (2) Temperature exposures consisted of acute and chronic treatments to simulate condenser transit and prolonged thermal plume entrainment. (3) The results showed that the various temperature zones presented by cooling water circuit of the power station would permit diatom growth, with growth rates that are marginally different form those at average ambient sea temperature. (4) Fundamental differences in the response of different diatom species to temperature stress result in the abundance of the more tolerant species such as A. coffeaeformis which dominate in an elevated temperature zone, such as that offered by the discharge canal of the power station.
