Coastal Condition (Combined) This layer is one of the South Atlantic LCC indicators in the estuarine ecosystem (both estuarine marsh and estuarine open water). It is an index of coastal condition capturing water quality, sediment quality, and benthic community condition. Reason for Selection This index measures the overall abiotic condition of the system, is well monitored, and is synthesized by the Environmental Protection Agency (EPA) every 5 years. It integrates measures of water quality, sediment quality, and benthic habitat quality. Input Data The EPA Coastal Condition Index (CCI) is a ranking derived from a water quality index, sediment quality index, benthic index, coastal habitat index, and fish tissue...
Long-term studies were used to examine (1) contrasting time scales and mechanisms of structural variations within two benthic communities and (2) the usefulness of long data sets for evaluating human impact. A 10-year study of a San Francisco Bay mudflat, the details of which are reported elsewhere, has revealed large short-term (on the order of months) variations in species abundances within a community composed predominantly of opportunistic species. The study site, located in a highly urbanized estuary, is subject to the influence of a nearby sewage-treatment facility. However, rapid changes in population size of the common species, in part due to periodic natural habitat disturbance, impedes the detection of...
