Bathymetric maps look a lot like topographic maps, which use lines to show the shape and elevation of land features.. On topographic maps, the lines connect points of equal elevation.On bathymetric maps, they connect points of equal depth. Finally, measurements indicate that indeed the use of FM pulses can result in a noisier bathymetry. For single-beam systems, increasing the horizontal resolution of the bathymetry measurements requires increasing the number of observations of the seafloor collected over a given distance.

Treating the drifter and echo sounder measurements as truth, the accuracies of the MR near-surface currents and bathymetry are 0.04–0.07 m/s and 1.2 m (or 7% of the mean water depth). However, direct high resolution surveys of near-shore bathymetry are relatively difficult to perform due to budget constraints and logistical restrictions. The bathymetry measurements could also help researchers better decipher the past hydrology of a region and its past climate, said Yehouda Enzel, Armon’s advisor at The Hebrew University of Jerusalem. To better characterize the water supply capacity of Clear Creek Reservoir, Chaffee County, Colorado, the U.S. Geological Survey, in cooperation with the Pueblo Board of Water Works and Colorado Mountain College, carried out a bathymetry survey of Clear Creek Reservoir.
