Students will discover from this text that oceans are major climate-controllers because of their large heat capacity. As a result, over a long period, oceans can store and transport heat from one location to another. Of particular interest is the ocean’s Conveyor Belt or thermohaline circulation, since both temperature and salinity are at the root of its existence. A major player in the thermohaline circulation is a process known as deep convection (DC), that mixes warm and cold waters, affects sea ice melting and how much solar radiation is absorbed. DC is being modeled by computers to help answer the overwhelming question: how significant are greenhouse gases against the backdrop of larger climate changes, and how self-correcting is the Earth system to these changes.
