Course Requirements Completing of all the assigned homework and a final exam. The final grade will be based 2/3 on problem sets and 1/3 on final exam. Students should enroll in four (4) units as either letter or S/U.

Description This course, Nearshore Physical Oceanography, will cover the basic physics of the nearshore and coastal regions spanning the surfzone to the outer shelf. Topics covered will include how surface gravity waves, winds, and tides force circulation and its intrinsic response across this region. Additional topics are also possible.
