Primary amines in California coastal waters: Utilization by phytoplankton

A new reagent, fluorescamine, provides a simple, rapid fluorometric measurement of primary amino compounds in seawater. The reagent detects as little as 0.2 r.lM (glycine equivalents) directly in 2 ml of seawater. Fluorescamine-positive primary amines in the region of Newport Bay, California, range from about 0.3 PM in nearshore waters to 14 PM in bay sediments. About half the fluorescamine-pos...

Health risk of bathing in Southern California coastal waters.

Urbanized areas often discharge large volumes of contaminated waste into coastal waters, which may pose a health risk to bathers at nearby beach areas. In this investigation the authors estimated the number of gastrointestinal and respiratory illness episodes associated with the microbial contamination of coastal waters among bathers at Southern California beaches from 2000 through 2004. Bather...

Antifouling pesticides in the coastal waters of Southern California.

After the United Nation’s International Maritime Organization banned the use of organotins in antifouling products, organic booster biocides were introduced as alternatives to these compounds. The purpose of this study was to measure concentrations of the antifouling agent Irgarol 1051, its major metabolite M1 (aka GS26575), and other antifouling pesticides (diuron, chlorothalonil, dichlofluani...

Optical Closure in Coastal Waters

Our scientific objectives encompass both empirical and theoretical investigations. Empirical objectives are: 1) develop new instruments and methods for measuring ocean-optical properties, 2) conduct systematic coastal ocean measurements for testing closure and for characterizing optical properties and the processes related to their changes, and 3) perform laboratory experiments to investigate o...
