The concentrations of the ionic, particulate, and total soluble copper in waters off Florida were determined spectrophotometrically. Most of the copper was in the soluble organic complex. Nearshore waters had significantly more total copper (approximately 20 µg/liter) than the waters flowing through the center of the Straits of Florida (approximately 10 µg/liter). Ionic copper concentrations were always less than 2µg/liter, and the particulate copper concentrations rarely exceeded 0.2 µg/liter.
