This modern, artistic wood chart of Martha’s Vineyard also illustrates the depth of the sea. This three-dimensional representation conveys the same bathymetric (measurement of water depth at various places) information found on Des Barres’ chart of the area. The various layers of wood in these charts demonstrate how the ocean gradually gets deeper the further one travels from shore. Soundings and bathymetry illustrate what exists under the water’s surface. Although not used for navigational purposes, these works of art visually convey depth of the ocean floor in a way that is not only easily understandable, but also captivating.
