Field trip to the Woods Hole Oceanographic Institution (WHOI): (DATE TBA) 2012; We'll be leaving Cambridge very early in the morning, back in the late afternoon. Our Host will be Dr. Bob Pickart; last time we visited the R/V Atlantis, the submersible Alvin, and toured the labs of WHOI; photos;

Outline

This course will cover observations and the understanding of ocean phenomena from local surface beach waves to the effects of the oceans on global climate. We will discuss ocean waves, the Coriolis force and ocean currents, the large scale temperature and salinity distributions and more. As part of the ocean's role in climate we will cover the wind-driven circulation and the Gulf stream, the thermohaline circulation and the potential instability of Europe's climate due to global warming, El Nino events in the equatorial Pacific ocean, and more. The basic fluid dynamics equations will be gradually introduced. A field trip to the Woods Hole Oceanographic Institution on Cape Code will be held during the course, which will be an opportunity to learn about sea-going oceanography as well.

The students will be introduced to the Matlab software for scientific computation and graphics, which will be used for some of the homework assignments.

Prerequisite: Mathematics/ Applied Mathematics 21, Physics 15/ 11, or equivalents, or permission of instructor.

Requirements

Semi-weekly homework will be given throughout the course. The best 90% of the homework will constitute 40% of the final grade. Each student will be invited to present a brief informal description of some aspects of the ocean circulation and its role in climate and possibly do a class presentation of a fluid experiment (20%), see details here for a list of possible subjects. The final exam may be a take home (40%).
