2 BACKGROUND & RELEVANCE Ditton et al., 1995, 1999, 2001, 2002 Links to tourism Included demographics of divers Lee, 2013 Corpus Christi a top tourism destination in TX Nature tourism comprises a large portion of all visitortrips Adams et al, 2007 USS Oriskany Malki et al, 2010 USTS Texas Clipper Stolk et al, 2004 Artificial reefs great for divers, help protect natural reefs Meyer & Holland, 2008 MPA in Hawaii seeing some damage from divers Riad et al., 2007 Applied weighted overlay for site suitability for groundwater artificial recharge locations Demesouka et al., 2013 Landfill suitability analysis using MC-SDSS

3 Recognize what constitutes acceptable artificial reef deployment sites suitable for recreational scuba diving OBJECTIVES Understand how the local economy benefits from scuba diving K. Mendenhall

8 METHODS AND SURVEY DESIGN In person/phone surveys of licensed full service dive shop owners and boat operators Online surveys of individual certified scuba divers via Qualtrics Site suitability via ArcMAP Economic Impact Analysis via IMPLAN V 3.1 with State Plus Package (Texas) Socio-demographics Use patterns Level of involvement Motivations Attitudes Expenditures

9 BROADER IMPACTS OF ECONOMIC ANALYSIS Assess economic benefits accruing from scuba diving Identify to what degree the local public benefits from scuba diving Determine actual and potential impacts of artificial reef development and deployment on the Texas economy Determine to what extent artificial reef deployment and development is an efficient public investment

10 ECONOMIC IMPACT ANALYSIS RESULTS DIRECT EFFECT SECONDARY EFFECTS INDIRECT INDUCED TOTAL EFFECT OUTPUT $1,698,713 $697,230 $1,109,354 $3,505,297 EMPLOYMENT DIRECT EFFECT SECONDARY EFFECTS INDIRECT INDUCED TOTAL EFFECT MULTIPLIER OUTPUT $1.00 $0.42 $0.66 $2.08 $2.08 EMPLOYMENT

11 BROADER IMPACTS OF GIS Determine what constitutes suitable scuba diving in Texas Gulf waters Identify what kinds of artificial reefs need to be developed to better suit scuba divers Determine optimal locations for artificial reef deployment to better suits scuba divers ANALYSIS

12 WHAT DO TEXAS DIVERS WANT M0a.com A day trip Close to a dive shop for diving needs Best visibility possible Structure in feet of water In proximity to an existing structure Wrecks Fishingdestin.com

13 WEIGHTING SCHEME Distance to viable boat dock Distance Weight Distance to full service dive shop Distance Weight Visibility Distance Weight Distance to existing structures Distance Weight Bathymetry Depth Weight = most favorable/most heavily weighted 1 = least favorable/least heavily weighted

14 WEIGHTED OVERLAY TABLE Weighted Overlay Table Raster Distance to a viable boat dock % Influence 40 Visibility 30 Distance to a full service dive shop Distance to existing structures Bathymetry 10 K. Mendenhall

15 WEIGHTED OVERLAY RESULTS

16 MOVING FORWARD Analyze local differences and preferences Compare with data prior to rig removals Compare with diving internationally Incorporate Qualtrics survey results Compare impacts with that of the recreational fishing industry Objective visibility measure Analyze where the divers are coming from Take in to account seasonality; weather, water temp, currents, visibility
