In 1922 a historic moment in cartography and oceanography occurred. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The second largest ocean on earth the atlantic drives our weather patterns including hurricanes and is home to many species from sea turtles to dolphins.
