Geology and Environmental Science
Mapping Paleocurrents: Using the Past to Understand the Present part of Cutting Edge:Oceanography:Activities
In this activity, students are given a series of world maps showing the different configurations of the continents through geologic history. Working back from the present, students reconstruct the location of past surface currents based on the location of the continents and global atmospheric circulation patterns. Students also need to consider the importance of oceanic gyres in global heat transport by identifying warm and cold currents, as well as, areas that in the past were isolated from hemisphere-scale gyres and as a result, experienced unusually cold or warm conditions.
Oceanography part of Cutting Edge:Oceanography:Courses
A basic survey of the physical, chemical, and geologic character of the world's oceans. Topics include physical and chemical properties of sea-water, atmospheric and oceanic circulation, the origins and dynamics of waves and tides, plate tectonics and the evolution of ocean basins, ocean sediments, coastal processes and landforms, and marine environmental issues. Course content focuses on both scientific processes and the exploration of how this scientific understanding can be applied to real world oceanographic issues. Labs provide hands-on opportunities in the field and laboratory, where students investigate oceanographic principles and processes through the scientific method.
