Polar Oceanography: Focusing on the Relationship with Thermal Salt Circulation and Climate Change
Sea ice drives the mid- and deep-ocean (thermohaline) circulation, an important component of the climate system, through the production of high-density water during its formation. In addition, the high albedo (high reflectance of solar radiation) characteristics of sea ice can exacerbate climate change and warming. In this intensive course, we will discuss ocean circulation, water mass formation, sea ice variability, and the role of sea ice in the ocean and atmosphere, including the latest topics in the polar and sea ice regions. In addition, research methods such as in-situ observation, remote sensing, and numerical modeling in the polar and sea ice regions will be introduced using actual research examples. By deepening understanding of oceanographic phenomena in the polar and sea ice regions, which are also important for global ocean circulation and climate change, students will be able to understand ocean and atmospheric circulation and change from a broader perspective. |
