1 Time Series for Oil Facility on East Timbalier Island Aerial Video Survey Program Pontchartrain Institute of Environmental Sciences University of New Orleans Karen A Westphal

2 The Aerial Video Survey Program has been acquiring photography and video of the northern Gulf of Mexico shoreline since Oblique aerial photography does not produce exact matches due to variations in altitude, camera angle and distance from the shore (and different photographers). Photos that matched well were scaled and aligned to illustrate the landscape changes that have taken place between time periods. Occasionally a pointer or symbol was added to assist with the visual comparison.

22 Relevant Coastal Restoration Projects  East Timbalier Island Sediment Restoration, Phase 1. State Project Number: TE- 25 Project Priority List (PPL): 03 Federal Sponsor: National Marine Fisheries Service (NMFS) Project Type: Barrier Island Construction Completion Date: 2000 Description: The objective of this project is to strengthen and thus increase the life expectancy of East Timbalier Island. The project called for the mining of 890,000 cubic yards of sediment and placement of the material in three embayments along the landward shoreline of East Timbalier Island. The project also included aerial seeding of the dune platform, installation of sand fencing, and dune vegetation plantings have been completed.  East Timbalier Island Sediment Restoration, Phase 2. State Project Number: TE- 30 Project Priority List (PPL): 04 Federal Sponsor: National Marine Fisheries Service (NMFS) Project Type: Barrier Island Construction Completion Date: 2000 Description: The project goal is to strengthen and increase the life expectancy of East Timbalier Island by placing dredged material along its landward shoreline. Additional rock has been placed on the existing breakwater in front of the island which will help protect the created area from erosion.  East Timbalier Island Sediment Restoration, Phase 1.
