Quizplus · Accepted Answer

Early cartographers were able to include information on the directions of currents, position of large rocks in harbors, and even sailing times. They also included various landmarks that would be helpful for navigation. Initially these charts did not have water related information like depths because they were just used to stimulate a sailor's memory of the journey rather than to specifically guide his path. Information can be found in the section Marine Scientists Use the Logic of Science to Study the Ocean.
