Scientists from the NOAA National Centers for Coastal Ocean Science (NCCOS) documented sediment and soil characteristics, erosion rates and biological communities within the sediment placement region and in undisturbed inter‐and subtidal regions of Mordecai Island from 2017 – 2019. The goal of these efforts was to quantify the immediate success of restoration efforts, evaluate ecological benefits and impacts of the project, and provide a baseline against which to measure future changes. This report summarizes the results of those efforts and provides a snapshot of the morphological and ecological status of Mordecai Island during that time. The work was funded through discretionary science funding from NOAA/NCCOS with supplemental support in the form of laboratory analysis provided by the USACE Engineering Research and Development Center.
