A Geospatial Assessment of Nearshore Sand Resources and Sediment Transport Pathways for Georgia Coastal Resiliency and Recovery
Principal Investigator: Clark Alexander, Skidaway Institute of Oceanography

  • Sand resources are needed to rebuild beach and dune systems to provide the same or better level of protection to lives and property, and to restore habitats that are degraded by events such as hurricanes and large storms. These sand resource data are critically needed in Georgia, as the sand resources on the continental shelf are the most poorly known of all the states along the East Coast. This project proposes to collect new, high-resolution data to build toward an understanding of the sand resources available on the Georgia shelf, and the transport pathways by which these sediments are redistributed. The focus will be on the three developed barrier islands that have not been renourished (Sea, St. Simons and Jekyll Islands) as these are the regions that may require renourishment in the future.

2014-2016 Projects

Adding dynamic information to resiliency planning: wetland mitigation and open space opportunities
Principal Investigators: Liz Kramer, University of Georgia; Craig Landry, University of Georgia; Shana Jones, University of Georgia

  • The objective of this project is to identify and prioritize the best sites for wetland protection, mitigation, restoration and migration along the Georgia Coast, taking account of potential future land use change and the impacts of sea level rise. Recognizing that local government financing of infrastructure has a 30-year life cycle, the researchers will identify and prioritize wetland sites that could be restored, created or protected based on their location and condition 30 years from now.

Black Gill Disease in Georgia Shrimp: Causes, Distribution, and Transmission
Principal Investigators: Marc Frischer, Skidaway Institute of Oceanography; Richard Lee, Skidaway Institute of Oceanography

  • The objectives of this project are to identify the cause of Black Gill in Georgia shrimp, develop tools to identify the source of Black Gill and conduct studies useful for forecasting and managing Black Gill in coastal Georgia. Through collaboration with the Georgia Department of Natural Resources and Georgia shrimpers, the results of this research will be utilized to guide the management of Georgia’s shrimp fishery.

Can the local food movement be an opportunity for Georgia seafood producers to participate in the inland seafood market?
Principal Investigators: Tracy Yandle, Emory University; Peggy Bartlett, Emory University

  • This study’s objective is to answer the broad question: “How can Georgia seafood producers use the burgeoning local food movement to increase their participation in the inland market and make sustainable, local fish available to a larger segment of the Georgia population?” The researchers will assess the potential of three innovative ways to bring Georgia seafood into the local food market (Community Supported Fisheries, placement in existing farmers markets and greater presence at farm-to-table restaurants). Recommendations of how each market could be developed will be provided, and the most economically advantageous option will be piloted.

Closing the water budget for the Satilla Basin, Georgia*
Principal Investigators: Marc Stieglitz, Georgia Institute of Technology; Elizabeth Kramer, University of Georgia

  • The goal of this project is to show proof of concept for being able to model the water budget for ungauged portions of the coastal zone. Prior to examining the effect of land use change and management of freshwater to the coastal estuary, it is necessary to prove that it’s possible to determine the water budget, especially prove that evapotranspiration (ET) can be modeled accurately. The results of this study would provide a better understanding for the development of a more targeted wetland restoration program, thereby enhancing the resiliency of estuary fisheries through the restoration of the timing of delivery of freshwater inputs.

Coastal Georgia Regional Wastewater Planning
Principal Investigators: Laurie Fowler, University of Georgia; Katie Sheehan, University of Georgia

  • With supervision and support from the Coastal Regional Commission, this project aims to develop a regional wastewater plan that will provide the framework for sustainable wastewater infrastructure decisions on Georgia’s coast. We will convene groups of experts and stakeholders, construct a framework for the plan, educate our constituents and analyze regional wastewater infrastructure alternatives according to a set of parameters chosen by our coastal stakeholders.

Creating a Model System for Sustainable Development: Striking a Balance Between the Ecological, Economic, and Social Needs of Jekyll Island State Park
Principal Investigator: Kimberly Andrews, University of Georgia; Katie Mascovich, University of Georgia; Tracey Tuberville, University of Georgia

  • As one of Georgia’s four barrier islands accessible by car, Jekyll Island is in a unique position to serve as a model for sustainable development. In order to balance maintaining a healthy beach ecosystem while developing Jekyll’s beachfront, this project focuses on accomplishing the following goals: monitor the response of the federally protected loggerhead sea turtle (Caretta caretta) to the developing and changing beach habitat; create a habitat change model that can be used in the development of Jekyll Island’s beach management plan; work with Jekyll Island stakeholders to promote sustainable development; and increase the environmental literacy of Jekyll Island’s guests and residents such that they become better beach stewards.

Evaluation of a turtle excluder device (TED) design for use in the cannonball jellyfish fishery operating in Georgia’s territorial waters
Principal Investigators: David Stasek, College of Coastal Georgia; James Page, Georgia Department of Natural Resources; Todd Mathes, Georgia Department of Natural Resources; Patrick Geer, Georgia Department of Natural Resources; Lisa Liguori, University of Georgia

  • The practice of harvesting jellyfish for human use is a relatively new endeavor in Georgia. Since fishing efforts began, several fishers have expressed concerns over the negative impact of the mandated use of the TED on jellyball catches. Gear-related concerns in this fishery need to be addressed. This study will develop and evaluate new TED designs to potentially increase jellyball retention in nets while still promoting sea turtle exclusion.

Increased Tidal Flooding in Coastal Georgia: Assessing the Barriers and Value of Acquiring and Relocating Property
Principal Investigators: Scott Pippin, University of Georgia; Shana Jones, University of Georgia

  • A strong need exists in Georgia to develop tools and information for local decision-makers so that they understand the growing risk posed by sea level rise and identify where acquisition and relocation might be an appropriate response. Where a risk analysis indicates that an acquisition program will be beneficial, local officials need information to help them overcome identified barriers to establishing such a program, in order to improve local resilience to flood risks. This project will calculate, using Tybee Island as a study area, 1) the up-front and long-term costs to the local government and 2) the benefits of generating Community Rating System (CRS) credits and reducing flood insurance rates with respect to acquiring the most at-risk properties currently subject to repeated flooding. The researchers will examine legal and policy barriers to property acquisition and analyze existing studies that demonstrate how green space increases property values and promotes community continuity.

Planning for Competitive Port Expansion on the U.S. Eastern Seaboard: The Case of the Savannah Harbor Expansion Project (SHEP)
Principal Investigator: Stephen Ramos, University of Georgia

  • This project will analyze the geographic coastal impacts of port competition and look at the unique circumstances of the Greater Savannah Metropolitan Region in planning for future growth of its port. The project will incorporate GIS to generate thematic maps, exploring issues related port expansion and river deepening. These include a regional impact analysis of the transportation and land-use changes, an impact analysis on local ecologies and government capacity in the area surrounding the port and job creation and economic development generated by the port.
