Summary of Activity and Data Gathered: Visited locations within Stellwagen Bank National Marine Sanctuary. A customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a conductivity, temperature, and depth (CTD) instrument was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties. Total stations 13; total CTD casts 13; total sediment samples 13; total video drifts (6 to 12 minutes, 1.4 to 2.7 gigabytes) 13; total seabed images 26; total sediment sample images 19.
Staff: Dann Blackwood
Notes: Travel to and from Plymouth, MA for day-cruises to Stellwagen Bank.
CTD required as for previous cruises.
Load Auk on Friday, Jan 27 in Plymouth, MA.

|Survey Equipment||Survey Info||Data Type(s)||Data Collected|
|SeaBOSS||The SEABed Observation and Sampling System (SEABOSS) was used to collect sediment samples with a modified Van Veen sampler and video images of the seabed with GoPro cameras mounted on the frame. A CTD was mounted horizontally on the SEABOSS frame and its maximum depth is approximately 1 meter above the seabed.||Surveys (biological)|

|Furuno satellite compass SC-30||The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at two second intervals with a horizontal accuracy of 10 m. The navigation antenna is located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition.||Navigation||2017-009-FA_nav (Navigation data collectd aboard the R/V Auk on Stellwagen Bank)|
|GoPro camera||Seabed video images were collected using a battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video camera mounted on the USGS SEABed Observation and Sampling System (SEABOSS). The SEABOSS system had two GoPro cameras and a Seaviewer camera attached to it. The Seaviewer camera had a live feed to the surface and was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. In the case of camera failure, the additional cameras provided backup video.||Photo|

|Nikon 7100 digital camera||Still images of sediment sample surfaces were collected using a hand-held Nikon 7100 digital camera with a resolution of 24 megapixels (6000 x 4000 pixels), using a 18-200x zoom lens with an aperture ranging from f3.5 to f5.6. A Nikon macro Speedlight was used for illumination.||Photo||2017-009-FA_SampleImages (Grab sample still images collected aboard the R/V Auk on Stellwagen Bank (JPEG image format.

|SBE 19plus V2 SeaCAT Profiler CTD||These data were collected with a Sea-Bird CTD (conductivity, temperature, depth) instrument - a SBE 19plus SeaCAT Profiler CTD. In addition to the CTD water column profiling, the CTD is equipped with auxiliary sensors to measure fluorescence and turbidity. This instrument was deployed on the USGS SEABed Observation and Sampling System (SEABOSS). The CTD is mounted horizontally on the SEABOSS frame and its maximum depth is approximately 1 meter above the seabed.||CTD|
