|Purpose||Sea floor mapping of Lake Winnipesaukee working with NH WRD; invasive species mapping project.|
|Location||Lake Winnipesaukee, Moultonborough, Carroll County, New Hampshire, United States, North America;|
|Summary||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.|
|Info derived||Geologic framework of Moultonborough Bay, Lake Winnipesaukee, NH.|
|Comments||Dates have changed from initial pre-cruise report.|

Sensor - SVP
This system is used to acquire the speed of sound within the water column.
This system acquires acoustic backscatter data (frequencies nominally of 100 and 500 kHz).
EdgeTech 424 chirp sub-bottom profiler
Sub Bottom Profiler
This system acquires chirp sub-bottom data (4 to 24 kHz).
These are the navigation data acquired during survey operations and stored in HYPACK raw format.
Surveys (biological), Experiments (biological), Species ID, Photo, Video, Geology, Biology
This system is used to acquire van veen grab samples of surface sediment, digital video and photographs of the seafloor surface.
SEA SWATHplus-M 234 kHz
This system is used to acquire swath bathymetry and acoustic backscatter.
