Seafloor Mapping
Wet Maps
Grade Level:
6th-8th grade (Earth Science/Technology)
Lesson Description:
High resolution bathymetric maps are essential for finding and exploring geological, archaeological,and biological features in the ocean. In this lesson, students develop and use models to explore seafloor features; analyze and interpret data to explain how multibeam sonar is used to identify patterns of ocean floor structures; construct three-dimensional maps; and learn how multibeam sonar technology extends the measurement and exploration capacity of modern ocean exploration.
