A fiber-optic fluorometry system is used in conjunction with a benthic flux chamber in an attempt to estimate fluxes of dissolved organic carbon (DOC) and polycyclic aromatic hydrocarbons (PAH) in situ from coastal marine sediments. These initial deployments in San Diego Bay demonstrate the usefulness of laser-induced fluorescence measurements for continuous DOC determinations and reveal the possibility...
Describes a benthic flux sampling device developed at the US Naval Command, Control and Ocean Surveillance Centre. The remotely operated device measures in-situ sediment-water contaminant exchange rates. It can operate in water depth to 50m and for up to four days at a time. Results of a series of deployment tests to determine its effectiveness in quantifying contaminant exchange rates are detailed.
