Bathymetric Maps
Bathymetry is the measurements of water depths. One way to visualize the seafloor is by using a contour map. Contours are lines drawn connecting points of equal depth. Its like connect the dots but with a twist. The lines are called isobaths a line on a map that connects all points having the same depth below sea-level.
