Climate Change Part 2 - Oceans ViewThe Climate Change Part 2 lesson uses GIS and media to explore a critical area of climate change research: glacial melting and its potential impact on the ocean currents. Evidence shows increased melting of glaciers in Greenland. The addition of fresh water to the North Atlantic threatens to alter the ocean's salinity in the North Atlantic region. Scientists have monitored the currents and conditions in the Atlantic Ocean since Ben Franklin discovered the Gulf Stream in the 1770. Recently, with the advent of satellites and enhanced buoy systems, scientists have been able to more accurately track the origin and movement of the ocean water. The conditions in the ocean are monitored using a combination of satellite sensing and ocean buoy data recording. There is much international attention to the region closest to Greenland; the origin of the dense water that drives (thermo= temperature, haline=salty) thermohaline circulation which is more commonly called the Oceanic Conveyer Belt. This lesson can be used on its own or in combination with two other lessons (Greenland and Impact View). When used together, this set of lessons will give students a deeper understanding of the phenomena of climate change. The other two lessons can be found in the ArcView 9.x lessons section of the K-12 website http://www.esricanada.com/english/3780.asp Before starting this lesson, please read the Teacher's Guide provided. * PLEASE READ: By downloading this lesson and data you have been deemed to agree to the terms below: THE LESSON AND DATA ARE PROVIDED "AS-IS," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, BY STATUTE OR OTHERWISE, INCLUDING, BUT NOT LIMITED TO ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT.
