Western and Atlantic Ecology Division Scientists To Provide Technical Support to Estuarine Numeric Nutrient Criteria Development by California State Water Resources Control Board

James Kaldy (WED) and Naomi Detenbeck (AED) have been asked by the Southern California Coastal Water Research Project (SCCWRP, Costa Mesa California) to assist in providing technical support to the California State Water Resources Control Board on the development of nutrient criteria for the State's estuaries. Dr. Kaldy's expertise will be used to evaluate how submerged aquatic vegetation (SAV) can be used as an indicator of eutrophication for a diverse set of California estuaries. Dr. Detenbeck is providing technical assistance and expertise with development of estuarine classification work, an integral part of California nutrient criteria development. The technical issues on SAV as indicators of numeric nutrient end points are complex, and the state of the science is such that expert opinion will be required to provide guidance to the California Regional Water Boards. This work is likely to generate at least one white paper synthesizing the state of the science on SAV as indicators in West Coast estuaries, as well as a classification system for California estuaries.
