Chemical Plume Mapping with the XZ-Profiler in the Providence River

Two dimensional maps showing directional current velocities (top panel) and the distribution of dissolved oxygen (bottom panel). Data acquired in real-time with the XZ-Profiler, in the Providence River region of Narragansett Bay, RI on August 31, 2000.  Note the presence of hypoxic (low oxygen) bottom waters.

The shipboard ADCP data (RD Instruments) on directional current velocities can be merged with the underway-chemical data to estimate directional chemical fluxes.
