Description:
Abstract:
These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Science Center (WHSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (<http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html>). This spatial dataset is from the study area located between Duxbury and Hull Massachusetts, and consists of high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples, video tracklines and bottom photographs). The data were collected during four separate surveys conducted between 2003 and 2007 (NOAA survey H10993 in 2003, USGS-WHSC survey 06012 in 2006, and USGS-WHSC surveys 07001 and 07003 in 2007) and cover more than 200 square kilometers of the inner continental shelf.
Purpose:
This data set includes the bottom photographs acquired with the large SEABed Observation and Sampling System (SEABOSS) during USGS survey 07003, conducted September 7-11, 2007 aboard the R/V Connecticut offshore Massachusetts in the Duxbury to Hull survey area. This data set was collected to ground-truth (verify) the acoustic data sets that were acquired during NOAA hydrographic survey H10993 (2003) and USGS geophysical surveys 06012 (2006) and 07001 (2007). The locations of these bottom photos can be found in the shapefile DH_BottomPhotos.shp. Bottom video were also taken at each station occupied by the SEABOSS (see shapefile DH_SeaBossTrackline.shp)

Data_Quality_Information:
Logical_Consistency_Report:
Gaps in sequential photo numbers exist. If camera was triggered accidentally on deck or picture did not come out, it was deleted.
Completeness_Report:
Only the subset of bottom photographs collected during the R/V Connecticut survey 07003 within the Duxbury to Hull survey area have been included in this spatial dataset. Seventy-seven stations were occupied within the study area between Duxbury and Hull. A total of 184 sampling sites were occupied during survey 07003. The bottom photograph that are not included in this report are from sites south of Brant Rock, Massachusetts and will be published in a subsequent data release focused on Cape Cod Bay. Any bottom photographs taken in water column or were otherwise not usable were deleted.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The JPEG photos alone do not represent spatial data, however the shapefile "DH_BottomPhotos" makes the link between these photos and the navigation from USGS field activity 07003. Navigation for survey 07003 used differential Global Positioning System (GPS). The recorded position of each sediment sample is actually the position of the GPS antenna on the survey vessel, not the SEABOSS sampler. The SEABOSS was deployed approximately 5 meters astern of the GPS antenna off the ship's J-frame on the starboard side. No layback or offset was applied to the recorded position. In addition to the +/-5 meter offset the SEABOSS may drift additionally away from the survey vessel when deployed to the seafloor. Based on the various sources for horizontal offsets, a conservative estimate the horizontal accuracy of the bottom photograph locations is 20-30 meters.

Source_Contribution:
The SEABed Observation and Sampling System (SEABOSS) was designed by the U.S. Geological Survey (USGS) for rapid and effective collection of seabed images and sediment samples in coastal regions. The observations from video and still cameras and the sediment data are used to explore the nature of the seafloor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate the acoustic remote sensing data. The SEABOSS is a simple system that can be deployed from both small and large surface vessels and operates in water depths up to 200m. It incorporates two video cameras, a still camera, a depth sensor, and a modified Van Veen sediment sampler. The elements of this particular SEABOSS system are held within a stainless steel framework that measures 1.2 x 1.2 meters and weighs 136 kilograms overall. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The digital camera, a Minolta DiMAGE A2, is mounted in a machined Delrin housing with a flat port and is set for 3264x2448 pixel images at the "fine" setting for compression. This allows the camera to be used for over 200 images with a 1 GB Compact Flash card without downloading. The system also has a PHOTOSEA strobe. Two lasers are set 20 cm apart (both as they are mounted on the SEABOSS frame and as seen in photographs and video on the seabed) for scale measurements. The red laser dots can usually be seen in the photo depending on the bottom type and the distance to the sea floor. A third laser is positioned at an angle so that when it intersects the other lasers, the SEABOSS is at the optimum height (approximately 75 cm) off the bottom for a still photograph. The camera is set to a manual focus and set to a default focus distance once the camera is powered up. The default focus distance is slightly less than the optimum height above the seafloor to account for optical distortion under water. All of the system's elements are powered from the surface vessel through a conducting cable. The winch operator views a video monitor so that the system can be maintained at an appropriate height above the bottom and obstacles can be avoided. Scientists also view video monitors and decide when to sample and take still photographs. Video displays include station number, water depth (from the depth sensor), and date, time, and geographic position (provided by a shipboard navigation system). The SEABOSS was deployed from the R/V Connecticut off the ship's J-frame on the starboard side. The vessel occupied one of the target stations and deployed the SEABOSS. The winch operator lowered the sampler until the seafloor was observed in the real-time bottom video. On most stations, the vessel and sampler drifted with wind and current for approximately 5-15 minutes. The SEABOSS operator monitored the real-time bottom video and acquired still bottom photographs at points of interest by remotely triggering the camera shutter. The number of photographs per station varied from 4-20 depending on the complexity of the bottom. The third laser on the system was set to an angle such that the optimum photograph height was 75 cm. The default focus on the camera was set to 50 cm. The imaged area is most often within 0.5 to 1.25 meters from left to right. Other camera settings are as follows: aperture is set at f/8; shutter speed is 1/125 second. The camera time during this survey was set to EDT, unless otherwise noted (see metadata for DH_BottomPhotos.shp (<https://pubs.usgs.gov/of/2009/1072/html/appendix1.html>) for details on when the time value was wrong and how it was corrected).
Process_Step:
Process_Description:
One hundred eighty-four target stations were occupied aboard the R/V Connecticut (USGS survey 07003) with the large SEABOSS (Blackwood and Parolski, 2001) that was equipped with a Van Veen grab sampler, a digital still camera, and a video camera. Seventy-seven of those sites are within the Duxbury to Hull survey area. JPEG photographs were acquired at each station. The digital photographs were downloaded from the camera and backed-up to a laptop and hard-drive four times during the sampling survey. The JPEG photos alone do not represent spatial data, however the shapefile DH_BottomPhotos.shp (also in this report, USGS OFR 2009-1072) makes the link between these photos and the navigation from USGS field activity 07003. The link is possible because the JPEG photographs EXIF header records acquisition time. However, there were errors in setting the camera's clock; see metadata for DH_BottomPhotos.shp for details on when the time value was wrong and how it was corrected.

Image names repeated for each subsequent day therefore the original JPEG images were renamed from the sequential, camera automatic filename (i.e. PICT001.JPG) to a filename with the download number (1-4) prepended to the filename (e.g. DL1_PICT001.JPG). For example, DL1 indicates the first download session.
