Equipment Used: Interferometric Bathymetry System, Valeport SVP, Chirp 424, Ashtech Z-Xtreme DGPS, F190 DGPS/IMU, Light Detection and Ranging (LIDAR), Other, Valeport Mini Sound Velocity Probe, Choke Ring Antenna, Water Level Recorder

Information to be Derived: Swath bathymetry and backscatter data, sub-bottom data; water level data from recovery of Seabird Gauges

Summary of Activity and Data Gathered: Geophysics in the surf zone and nearshore and around Hewes Point . Colletcted interferometric swath bathymetry (37 lines) and swath backscatter(37 lines), chirp sub-bottom (32 lines), sound velocity profile casts (10), and recovery of the seabird water level gauges.

Notes: This FAN is linked with several other FAN numbers working together yet gathering different portions of data. 1) Geophysics in the surf zone and nearshore and around Hewes Point (bathymetry & sub-bottom) 2) Sediment Sampling 3) Lidar Ground Control Surveys 4) Recovery of Water Level Sensors (Seabird Gauges), and 6) Back-barrier coring. Direct questions to Jennifer Miselis. Additional Vehicles: Green Suburban and Ford Excursion. There are several activities that will be part of the larger geophysical effort. FANs are assigned by platform: R/V Sallenger = 13BIM02 collecting interfermometric swath bathy (37 lines) and backscatter (37 lines); chirp sub-bottom (32 lines), and sound velocity profile casts (10). The R/V Twin Vee = 13BIM03 collecting single beam bathy; R/V Shark jet ski= 13BIM04 collecting single beam bathy; and the 14' skiff 13BIM05 and 13BIM06 collecting sediment cores and lidar ground control.
