Description:
Abstract:
The U.S. Geological Survey, in collaboration with the National Oceanic and Atmospheric Administration's (NOAA) National Marine Sanctuary Program, conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary region from 1993 to 2004. The mapped area is approximately 3,700 square km (1,100 square nm) in size and was subdivided into 18 quadrangles. Several series of sea floor maps of the region based on multibeam sonar surveys have been published. In addition, 2,628 seabed sediment samples were collected and analyzed and approximately 10,600 still photographs of the seabed were acquired during the project. These data provide the basis for scientists, policymakers, and managers for understanding the complex ecosystem of the sanctuary region and for monitoring and managing its economic and natural resources.
Purpose:
These data provide the locations of seabed sediment samples taken in the Stellwagen Bank National Marine Sanctuary region from 1993 to 2004. In addition to location information, the data also provides sediment analyses of each sample. See attribute section for complete description. The data for all of Stellwagen Bank is available as a shapefile.
Supplemental_Information:
These data are provided in shapefile format covering the entire Stellwagen Bank study area. The metadata bounding coordinates refers to the whole dataset.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The seabed sediment sample locations were plotted in ArcMap 9.3 to ensure geographic location and station names were correct.
Logical_Consistency_Report:
Data was sorted by station number to check for duplications. No other checks for topological consistency were preformed on this data.
Completeness_Report:
This shapefile has the locations for all seabed sediment samples taken between 1993 and 2004 on Stellwagen Bank as part of this project. We did not always collect photographs and video at stations where the purpose was just to collect sediment. All available grain-size data collected by the research cruises are included in this data set.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
These data were navigated with a Differential Global Position System (DGPS); they are accurate to +/- 10 meters horizontally. During deployment, the camera system hangs directly below the side of the ship, and the recorded navigation data closely approximates the position of the camera system near the seabed. The ship is oriented so that wind and waves will not cause it to drift over the conducting cable attached to the SEABed Observation and Sampling System (SEABOSS).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Depth was acquired using the ship fathometer until 1998. After 1998 depth was acquired using the depth sensor on the SEABOSS. Depths are accurate to +/- 1 meter.

Source_Information:
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 200 m. It incorporates two video cameras, a still camera, a depth sensor, and a modified Van Veen sediment sampler. The elements of the SEABOSS system used on Stellwagen Bank are housed within a stainless steel framework that measures 1.2 x 1.2 meters and weighs approximately136 kilograms overall. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The height of the camera above the seabed (76 cm; 30 in) initially was determined by viewing an object hanging from the SEABOSS below the video camera; when the object touched the seabed, the camera height was appropriate for still photography. Later in the project, the camera height was determined by viewing a pattern of laser beams on the seabed. Two parallel lasers are set 20 cm apart on the SEABOSS frame and project onto the seabed for scale measurements. All of the system's elements are powered from the surface vessel through a conducting cable. Video displays include station number, water depth (from the depth sensor), and date, time, and geographic position (provided by a shipboard navigation system). During deployment, the camera system hangs directly below the side of the ship, and the recorded navigation data closely approximates the position of the camera system near the seabed. The ship is oriented so that wind and waves will not cause it to drift over the conducting cable attached to the SEABOSS. The winch operator uses a video feed from the system to maintain the camera at the proper height above the seabed and to avoid obstacles. The scientist uses the video to decide when to take a grab sample of seabed sediment.
Process_Step:
Process_Description:
Annual research cruises visited stations from 1993-2004 and took seabed sediment samples using the SEABOSS that was equipped with a modified Van Veen grab sampler, a still camera and video cameras. The modified Van Veen sediment grab sampler is located in the center of the SEABOSS frame. Before deployment, the grab's buckets (jaws) are opened by collapsing the extended arms to a near-horizontal position and locking them in place with two catches. The sampler operates passively to sample the seabed; it is not spring-loaded. To collect a sample, the SEABOSS is lowered to rest gently on the seabed, and the time is recorded for navigation purposes. When the cable is slack, the two locking catches automatically release by gravity. As the cable is retrieved, the grab sampler's arms are pulled upward closing the bucket around the sediment, and the SEABOSS is lifted off the seabed. Weight can be added to the SEABOSS frame, making it harder to lift off the seabed, which results in the grab buckets closing more tightly around the sediment. The SEABOSS is retrieved and set upon a wooden platform that keeps the sampler buckets and camera systems above the deck. The sampler's arms are maintained in the upright position by holding them or by maintaining tension on the cable; the doors on the upper sides of the buckets are opened; and the sediment is retrieved. For this project, the upper 2 cm of sediment, representing the surface of the seabed, was removed with a rectangular shovel 2-cm deep and stored in a plastic bag for analysis ashore. The remaining sediment was dumped into a tray located on the deck below the sampler, and the Van Veen grab was washed in preparation for the next site.

Process_Description:
Station sediment sample analyses records were exported from the lab's database using Microsoft Excel 2007 (12.0.6504.5001) SP2 MSO (12.0.6425.1000). Some fields were deleted from the sediment lab analysis report that are unnecessary to our purpose. A mud weight percent column was added to the exported Excel spreadsheet since mud was found to be an important seabed characteristic in the Stellwagen region. Second, a quad column was added to organize the data into eighteen individual quadrangles. Third, Julian Day and time was complied in another column. Fourth an original Excel column, "Field ID" was reformatted as a text field for ease of import into ArcGIS. The reason being during the project, the station numbering scheme was not consistent, so that some station names used a decimal number format and some a number and letter format. For the purpose of this report, all sediment sample stations were renamed using the number and letter format for the station name where necessary. For example, station 3131.1 is now named 3131a. Lastly, headers were applied to the exported sediment sample Excel file. A check of the exported data was conducted against the lab's database to ensure consistency.

Station number for samples collected during this project in the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The stations were named using a number and in some instances a letter (3131a) or a decimal number (3131.1) suffix was appended. During the project, this station numbering scheme was not consistent, so that some station names used one format and some the other. For example, station 3131.1 is now named 3131a.
