ArcGIS Animation: Deepwater Horizon Oil Spill

http://students.uwf.edu/ylm2/DeepwaterHorizonOilExtent.avi

The above animation shows the deep water horizon oil extent between April 24, 2010 through May 26Th 2010. I was having trouble with the projections on this assignment. I tried to use the Projections & Transformations/Feature/Project tool in ArcCatalog and could not get it to work. I finally checked out the discussion board and found Dily's post to be very helpful. With using the Define Projection tool on each layer to set the property to Unknown and then using the Define Projection tool again to redefine each layer to GCS NAD 1983. I was able to go back and Project each feature to UTM NAD 16N. It worked like a charm.
