This dataset is a digital surface model of the roughness for five (of six) sites where known rock structures exist in the St. Croix River. Roughness is the degree of irregularity of the surface...
-
This dataset is a digital elevation model (DEM) of the bathymetry for six sites where known rock structures exist in the St. Croix River. The DEMs have a 10-cm resolution (Boom site is 0.5-m) to...

This dataset is a digital image mosaic of sidescan for six sites where known rock structures exist in the St. Croix River. Sidescan sonar emits conical or fan-shaped beam down across a wide angle...
-
These data are digital hillshades of the bathymetry for five (of six) sites where known rock structures exist in the St. Croix River. Hillshades are shaded relief surfaces created by the...
-
This dataset is a digital surface model of the slope for six sites where known rock structures exist in the St. Croix River. Slope is the gradient, or rate of maximum change in elevation, and is...

This dataset is a digital surface of depth-averaged flow velocities for six sites where known rock structures exist in the St. Croix River. Acoustic Doppler Current Profilers (ADCP) are used to...
-
This dataset is a digital image mosaic of the backscatter for five (of six) sites where known rock structures exist in the St. Croix River. Backscatter is the strength of the returned signal, or...
