Impact of Point and Non-point Source Pollution on Coral Reef Ecosystems In Mamala Bay, Oahu, Hawaii based on Water Quality Measurements and Benthic Surveys in 1993-1994 (NODC Accession 0001172)

browse graphicPreview graphic
The effects of both point and non-point sources of pollution on coral reef ecosystems in Mamala Bay were studied at three levels of biological organization; the cell, the population and the community. The results show a uniform lack of negative environmental impact. Calcification and growth show no relation to point or non-point sources of pollution within the bay. Neither do species abundance patterns, diversity or community structure. Changes in water quality caused by rainfall and wave events are too small and too short lived to affect coral reef ecosystems in the bay. Species abundance patterns and community structure of coral ecosystems in the bay appear to be related to the effects of large hurricane wave events in 1982 (Iwa) and 1992 (Iniki). Recovery of coral reef ecosystems in Mamala Bay is now taking place from damage sustained during and after these storms, and from an earlier period of severe environmental degradation prior to 1977 when raw sewage was discharged into the bay at 13 m depth off Sand Island. Not withstanding future disturbances, existing sources of point and non-point source pollution are not expected to interfere with the recovery process now ongoing in Mamala Bay, and long-term biological processes should eventually return the coral ecosystem to a more mature successional stage. This data set includes surveys from 16 stations in Mamala Bay with comparisons to Hanauma Bay and Sunset Beach. Coral data types include percent coral cover, calcification rates of P.Lobata, bioerosion of P.Lobata, and coral species diversity. The data also includes water quality parameters for control periods, after wave events, and after rain events. Finally, data from sediment traps are given.

Purpose The purpose of the Mamala Bay Study is to develop an Integrated Coastal Management Plan in order to protect the environment and public health of this unique embayment off leeward Oahu in the Hawaiian Islands. Having resulted from a Consent Decree of the United States District Court in Honolulu, Hawaii, the study called specifically for: 1) An analysis of point and non-point source discharges into Mamala Bay, 2) A determination of the effects of these discharges on water quality, ecosystems and public health, and 3) A management plan to reduce pollution and improve water quality in the bay. The study was divided into twelve sub-projects. This report presents the results of one part of MB-9 which dealt with ecosystem response and was charged with identifying pollution impacts on target or receptor aquatic species in the water column and benthic environments.
