    • 700kHz Bathymetric Slope of select Rock Outcrops of the St. Croix River, May 2021

    Metadata Updated: July 6, 2024

    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 derived from the DEM. Slope measures will be used for investigating the use of hydroacoustic technologies for quantifying habitat for imperiled mussels Spectaclecase (Margaritifera monodonta) and Salamander (Simpsonaias ambigua) typically associated with rock structures (e.g., wing dams, revetment) in rivers. Slope is a driver of energy below the water and influences biotic diversity, distribution, and the functional traits of those biota. Slope is expressed in degrees; it calculates the maximum rate of change in value from one cell to its neighbors. The lower the slope value, the flatter the terrain; the higher the slope value, the steeper the terrain. Multibeam sonar data were collected using a Norbit integrated wide band multibeam system compact (iWBMSc) sonar unit. All hydroacoustic data were collected in early May of 2021, and the slope rasters are provided in GeoTiff format.
