Lecture 16: The Ocean and Climate; El Nino Today we will cover: 1.Surface Currents ----Warm currents ----Cold (upwelling) currents 2. El Nino 3. Downwelling and thermohaline currents 4. Sea Surface Temperature (SST) and Ocean Heat Storage 5. Carbon and the Ocean The major ocean currents are ____________ currents. The ______________ are responsible for many of the Earth's great ocean currents. The winds of the subtropical highs push the water beneath them, creating ocean currents. These ocean circulation systems, which are driven by the subtropical high pressure areas, are called ________________ (which means a spiral, or vortex). The circulation of ocean currents around subtropical highs are called: A. Hadley currents B. Ferrill currents C. Gyres D. Subtropical circuits T/F ocean currents are driven by the winds around the subtropical highs. http://video.google.com/videosearch?hl=en&q=plastic+in+the+ocean&um=1&ie=UTF- Answer the following questions from the video above. Many seabirds eat fish. What do the fish eat? Are petroleum based plastics biodegradable? When scientists compared the weight of plastic in the sea to the weight of zooplankton, what did they find? Where do these plastics accumulate? What are adult birds feeding their chicks? What was found in the digestive system of the dead bird? What are “nurdles”? Why are the tan pieces a particular problem?

What shape is a particular problem, and why? What collects on plastic particles? Warm ocean currents Warm ocean currents are corridors of warm water moving from the _________ towards the ______ where they release energy to the air. The _________ is a famous warm ocean current. After it crosses the Atlantic, it is called _________________ This ocean current warms Northern Europe. The ____________ current warms Japan. The ______________ currents occur near the equator, where the __________ drive the ocean surface waters westward in a concentrated channel along the equator. As these surface currents approach the western margins of the oceans, the water actually piles up against the eastern shores of the continents. This phenomenon is known as the ______________ . Sea levels are higher here. The piled-up ocean water then spills northward and southward. In the Northern Hemisphere, the Gulf Stream and Kuroshio (current east of Japan) move north at great speeds. The circulation systems are offset towards the
