Autonomous water column profilers are deployed over an area and each independently samples attributes in its water column to provide a three dimensional array of data points. The profilers are negatively buoyant and autonomously assume positive buoyancy; for example, by jettisoning a ballast weight, preferably collecting and storing measurements at programmed times or depths when descending and again when ascending. The devices can be recovered for accessing onboard memories or a wireless communications system can be employed for uploading data to a transponder. The profilers can be deployed from marine vessels, aircraft, or remotely operated vehicles and are advantageous for monitoring oil well leaks or spills, assessing dispersant programs when ameliorating released oil, for sensing natural seeps, and similar applications.
