Answer to Question 1

ANS: A
Although the Meteor expedition introduced the use of modern optical and electronic equipment, the
echo sounder was considered the most important. An echo sounder is a device that bounces sound
waves off the ocean bottom to study the depth and shape of the seafloor. Information can be found in
the section Contemporary Oceanography Makes Use of Modern Technology.

Answer to Question 2

ANS: B
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.
