The proposed plan will use remote sensing techniques and targeted in-situ observations to monitor the post-restoration evolution of beaches, dunes, vegetative cover, and sediment budgets at beach and dune restoration sites specified in the RFP. We will use these data to evaluate if/how restoration projects improved ecological
outcomes and decreased storm vulnerability relative to unaltered environments, thereby providing input necessary for estimating cost-effectiveness. The work as part of this field activity will focus on in-situ monitoring of sediment transport and water-quality in creeks within two of the restored marsh/dune sites.
Equipment or personnel only. Data, if any, are managed under a different field activity.
Location
Stone Harbor and Thompsons Beach, New Jersey, United States, Atlantic Ocean and Delaware Bay.
Summary
Recovery 1115D, 1116D, 1118CD, 1119D: On July 16, 2019, the YSI EXO2 and RBR Dwave were recovered from mooring 1116D. The Sontek IQ Plus measurements at mooring 1115D were stopped and data downloaded. On July 17, 2019, the YSI EXO2 and RBR Dwave were recovered from mooring 1119D and the Nortek Aquadopp was recovered from mooring 1118CD. Data was downloaded from all recovered instruments and archived on a WHCMSC file server.
Deployment 1115E, 1116E, 1118E, and 1119E: On July 16, 2019, the Sontek IQ Plus was configured to continue collecting data at mooring 1115E. A YSI EXO2 and RBR Dwave were deployed at mooring 1116E on a bottom lander platform. An SP80 RTK receiver was used to get the horizontal and vertical positions of 1115E and 1116E platforms as well as a cross-sectional survey of the marsh channel for Sontek IQ Plus flow calculations. On July 17, 2019, the Nortek Aquadopp was deployed at 1118E and a YSI EXO2 and RBR Dwave at mooring 1119E.
