STANDARD FORM 330 (REV. 312013) PAGE 2 shallow-water habitats to offshore reef habitats spanning depths between 11 feet and 90 feet and included anticipated direct and indirect impact areas of the PENIP. Pinnacle scientific divers participated in all aspects of the field data collection during this project. The coral reef habitat baseline data collected during the ESA and RECON Surveys will be used to inform the design of future surveys, including pre-construction, during construction, and post-construction. Pinnacle) installed multiple oceanographic instruments to collect hydrod ynamic field measurements in the vicinity of the Port Everglades Harbor. The field measurements will be used in support of model verification for sediment transport. The objective of the numerical model is to understand the fate of suspended sediment from dredge material during the proposed Port Everglades Harbor navigation channel deepening and widening project. Pinnacle installed six tide gauges – one gauge each at Port Everglades Inlet, near the Port Everglades Harbor Main Turning Basin, Tarpon River/New River near S. Andrews Ave., Port Laudania (Dania cut-off canal), Intracoastal Waterway (ICWW) near Hillsboro Inlet, and Dumfoundling Bay on 23 and 29 June 2016. There was a delay in deploying the tide gauge at the Tarpon River/New River Station due to sewage leaks in the Middle and New Rivers, the Florida Fish and Wildlife Conservation Commission prohibited access to the New River on 23 June through 27 June 2016. On 29 and 30 June 2016, Pinnacle installed four Acoustic Doppler Current Profilers (ADCPs) to m easure current flow velocity – one ADCP each at Port Everglades Inlet (just west of the jetty), ICWW near the SE 17th Street Bridge, the Southport Access Channel (SAC) between Eller Drive and N. Ocean Drive, and the SAC south of the Turning Notch. During instrument deployment, each of the tide gauges and ADCPs were inspected and data was downloaded to ensure that data was being collected. After inspection the instruments were reinstalled for the remainder of the deployment. On 1 and 2 August 2016, after a t otal deployment period of 30 days, the ADCPs and tide gauges were retrieved for final data download and processing. Pressure data collected by the tide gauges was converted into water levels and provided in NAVD88. Flow velocity data was processed accounting for water depth, height of instrument, blank distance, bin size, side-lobe error and tide range. On 8 December 2016, Pinnacle installed ADCPs to measure offshore wave properties at two stations located approximately four and six miles north of the Port at depths of 40 and 112 feet (12.2 and 34.1 meters), respectively. Additionally, a tide gauge was reinstalled in the Port Everglades Inlet to collect reference water level data during the December ADCP deployment. The two ADCPs were recovered on 13 December 2016 for instrument inspection and data download, and then redeployed. Upon data inspection, it was determined that the ADCP installed at the deep (112 -foot) station was not working correctly. A new ADCP was deployed at the deep station on 15 December 2016; and on 22 December 2016 the instrument was inspected and data was downloaded before it was redeployed to ensure that the new instrument was in working order. The tide gauge in the Port Everglades Inlet was recovered 15 December 2016 for inspection and data download, and then redeployed. On 18 January 2016 the two ADCPs and the tide gauge were retrieved for final data download and processing. 109
