Research has shown that in Currituck Sound the primary factor limiting SAV distribution is water clarity. Data collection in the last several months has suggested an expansion of SAV in some shallow regions of Currituck Sound. An understanding of SAV depth distribution and light availability in this system has provided water depth zones to differentiate the likelihood ofsustaining planted SAV. Changes in water clarity driven by Colored Dissolved Organic Matter (CDOM) is likely changing SAV growth on annual timescales. In addition, shoreline erosion is likely impacting water clarity and certainly will influence construction along the banks. SAV in the sound will likely be impacted by construction and shading post construction of the Mid- Currituck Bridge. In addition, studies have shown that shorelines near the Mid-Currituck Bridge terminus on the east and west side are experiencing significant erosion rates. This research will focus on expanding data collection near the bridge corridor. The project will further develop the SAV mitigation tool by collecting the necessary higher resolution data (e.g., shoreline position, bathymetry, SAV presence, proximity to existing vegetation, water quality/clarity) to focus future SAV mitigation sites.
