Navigation was updated from NDSF shipboard model using features in backscatter image to determine offsets at track crossing. For 32 crossings, offsets ranged from 0-175m, with mean 96±44m. A spline fit pinned with these specified offsets at the track crossings was computed using algorithm written by Jeff Gee, SIO, in 2004.
