The February JASA Express Letters cover features Figure 2b from the article, “Scattering measurements of rocky seafloors using a split-beam echosounder,” by Jen A. Gruber and Derek R. Olson. The image depicts a comparison of estimated bathymetry with ground truth from California State University, Monterey Bay, plotted in across-shore and along-shore coordinates.
