Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few brief phrases about the ocean on each slide. Information addresses ocean zones, light filtration, salinity, water movements, and other physical characteristics. Then it introduces marine animals from microscopic plankton to the enormous whale. Use this slide show as a skeleton for building an entire oceanography and marine biology unit!
