    Collection Overview: PI: Dr. Craig Glennie, University of Houston. NSF Project. The survey area is located over the confluence of Blue and Colorado rivers south of Kremmling, Colorado. Data were collected to test the Aquarius bathymetry laser since the confluence creates a variety of conditions with clear and muddy waters mixing from the two rivers. The Aquarius was tested for bathymetric performance with respect to water turbidity within the rivers. The data on OpenTopography are from the Gemini instrument. Bathymetric point cloud data (LAZ) from the Optech Aquarius sensor are available via the "bulk download" link below.
