Carbon Sequestration and Modern Sediment Dynamics
Presentation
Overview
Overview
Description
The shoreline of the lower Cape Fear River estuary is subject to a combination of erosive forces such as currents, wind waves, and vessel wakes. The estuary is also home to vital fringing marsh habitat and sites of significant cultural and historic value. To mitigate the impacts of erosion along one of these shorelines, novel wave attenuator structures were installed at Brunswick Town Fort Anderson (BTFA) in 2017. Vessel wakes from large cargo ships that pass close to the site have exacerbated the rate of e rosion in recent years. This project aims to examine the impact of the attenuators on shoreline morphology and carbon storage. This will be done by collecting sediment data to examine grainsize, sediment composition, and to determine carbon sequestration. Additionally, changes in marsh shoreline morphology over time will be examined. The results of this study will provide insights into the long term effects of shoreline protection structures on sediment dynamics. Findings can be used in future management an d restoration efforts in riparian marsh habitats.
