Equipment Used: Sensor - SVP, Klein 3000, EdgeTech 424 chirp sub-bottom profiler, HYPACK, SeaBOSS, SEA SWATHplus-M 234 kHz
Information to be Derived: Geologic framework of Moultonborough Bay, Lake Winnipesaukee, NH.
Summary of Activity and Data Gathered: Geophysical survey was conducted within Moultonborough Bay, Lake Winnipesaukee using high-resolution sidescan-sonar, swath bathymetry, and chirp sub-bottom profiler. Sediment samples, video and bottom photographs were collected to ground truth the geophysics. These data will lay the foundation for further habitat studies within the Bay.
