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, Coastal and Marine Geology Program, Woods Hole Science Center. 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 reserves, 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 Cape Ann and Salisbury Beach Massachusetts project area. The data collected in two separate surveys in 2004 and 2005 and cover approximately 325 square kilometers of the inner continental shelf. High resolution bathymetry and backscatter intensity were collected in 2004 and 2005. Seismic profile data, sediment samples and bottom photography were also collected in 2005.
Purpose:
This data set includes the bottom photographs acquired with the large SEABed Observation and Sampling System (SEABOSS) during USGS survey 05005, conducted September 18-20, 2005 aboard the R/V Connecticut. This data set was collected to ground-truth (verify) the geophysical data sets that were acquired immediately preceeding this sampling survey (September 8-16, 2005). The locations of these bottom photos can be found in the shapefile BottomPhotos.shp. Bottom video were also taken at each station occupied by the SEABOSS (see shapefile SeaBossTracklines.shp)

Horizontal_Positional_Accuracy_Report:
The JPEG photos alone do not represent spatial data, however the feature class/ shapefile "BottomPhotos" makes the link between these photos and the navigation from USGS Survey Number 05005. Navigation for survey 05005 used Real Time Kinematic (RTK) GPS from a base station established by USGS for this survey. RTK-GPS provides horizontal positional accuracies on the decimeter scale. The recorded position of each sediment sample is actually the position of the GPS antenna on the survey vessel, not the SEABOSS sampler. No layback or offset was applied to the recorded position. The SEABOSS was deployed approximately 10 meters astern of the GPS antenna and 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 SEABOSS location is 30-40 meters.

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 (on the SEABOSS frame or on the bottom) 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 by the A-Frame on the stern. 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 5-10 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 3-26 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.

Process_Description:
Eighty-seven target stations were occupied aboard the R/V Connecticut (USGS survey 05005) with the large SEABOSS (Blackwood and Parolski, 2001). JPEG photographs were acquired at each station. The JPEG photos alone do not represent spatial data, however the shapefile BottomPhotos.shp (<https://pubs.usgs.gov/of/2007/1373/GIS/shapefile/BottomPhotos.zip>) makes the link between these photos and the navigation from USGS Survey Number 05005. . The link is possible because the JPEG photographs EXIF header records acquisition time. However, the time recorded is local time, not UTC time. In addition, the local time is off by 47 seconds. The total time adjustment was +4 hours 47 seconds.

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 date prepended to the filename (e.g. 919_pict001.jpg). For example, 919 indicated September 19th. This date is based on local time, not UTC time.
