The contour interval is printed in the margin of each U.S. Geological Survey (USGS) map. Bathymetric contours are shown in blue or black, depending on their location. They show the shape and slope of the ocean bottom surface. The bathymetric contour interval may vary on each map and is explained in the map margin.

Hope it helps you ✌
