We propose Ranger ES, a low cost, autonomous underwater vehicle (AUV) for three-dimensional profiling and water samplings of chemical, physical, and biological parameters of oceanic and fresh waters. The AUV will be programmable by point and click to analyze a volume of water continuously for the selected parameters. After returning for pickup after a days run, it will download its data into an intuitive graphical user interface and visual profiling tool, which will permit the user to draw inferences while still in the field, as well as storing the runs data for further analysis. The systems continuous, granular profile volumes captured with reduced cost of personnel and ship- time imposed by existing technology will enable new insights into aquatic systems for research, management, or regulatory purposes. Specific capabilities of the initial design will be derived from interviews of potential end users both before and after a live technology demonstration. SUMMARY OF
Anticipated Results: Results in Phase I will be: 1) a summary of guidance from representative users regarding sampling capabilities of the proposed Ranger system, 2) demonstration of data capture at sea, 3) summary of input from representative users following demonstration, 4) final report. In Phase II, we will implement a low cost vehicle and data analysis and presentation system suitable for unattended use in ocean and fresh water survey in research or management applications
