This lesson allows students to consider navigation around Antarctica, where longitudinal lines converge at South Pole. Through this study, students should learn about polar stereographic projection, satellites, navigation using various instruments, Antarctic geography, and NASA’s Operation IceBridge airborne mission. In the first part of this 55-80 minute lesson, students will be faced with a dilemma. Their task will be
NASA’s Operation IceBridge (OIB) flies airborne missions each year over both Polar Regions, collecting ice thickness and extent data on glaciers, ice caps, ice shelves and sea ice. This data is useful to many disciplines studying climate, weather, ocean circulation, sea level and many related fields. The National Snow and Ice Data Center (NSIDC) houses and organizes the data

Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
