Marine Environmental Assessment at Three Sites in Pearl Harbor, Oahu, August-October 1978

摘要

Marine environmental investigations were conducted at three sites in Pearl Harbor, Oahu, during the period Aug-Oct 78. Data were obtained from planktonic, epifaunal, nektonic and benthic assemblages of the resident ecosystem. These studies were designed to evaluate the impact from cooling water systems(both intake and discharge effects) in areas adjacent to study sites. Entrainment, impingement and entrapment were judged to be the primary intake factors capable of causing adverse impact. Elevated temperatures of effluent cooling water were considered the major discharge perturbation. Analysis of data suggest that minor, localized adverse impacts from cooling water systems occur at the two former power plant sites in Pearl Harbor. No impact from the Submarine Training Center discharge was detected. The harbor contains a complex estuarine ecosystem which has undergone many changes due to human activities. Present ecological conditions indicate that harbor biota have a remarkable resiliency to various perturbations. Representative important species of harbor organisms have been selected and are discussed in relation to cooling water system impacts. Tabulations of data collected, listing of organisms identified and detailed descriptions of marine environmental survey techniques used during this study are presented. (Author)
