Edition: 1.0 Series_Information: Series_Name: Open-File Report Issue_Identification: 2010-1006 Publication_Information: Publication_Place: Woods Hole Coastal and Marine Science Center, Woods Hole, Massachusetts Publisher: U.S. Geological Survey, Coastal and Marine Geology Program Online_Linkage: http://pubs.usgs.gov/of/2010/1006/ 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 Coastal and Marine Science Center (WHCMSC). 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 of coastal Massachusetts, primarily in water depths of 3-30 meters deep. 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). The data collected in the study area located in Northern Cape Cod Bay Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection), and ground validation (sediment samples, video tracklines, and bottom photographs). The data were collected during five separate surveys conducted between 2006 and 2008 and cover 480 square kilometers of the inner continental shelf. More information about the individual USGS surveys conducted as part of the northern Cape Cod Bay project can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage: 06012: http://quashnet.er.usgs.gov/data/2006/06012/ 07001: http://quashnet.er.usgs.gov/data/2007/07001/ 07002: http://quashnet.er.usgs.gov/data/2007/07002/ 07003: http://quashnet.er.usgs.gov/data/2007/07003/ 08002: http://quashnet.er.usgs.gov/data/2008/08002/ Purpose: The purpose of this dataset is to record the trackline navigation along which bottom video was recorded and using the 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 Northern Cape Cod Bay survey area. This data set was collected to ground-truth (verify) the acoustic data sets that were acquired during USGS geophysical surveys 06012 (2006), 07001 (2007), 07002 (2007), and 08002 (2008). High-resolution digital photographs of the seafloor were also taken during the video drift (see shapefile CCB_BottomPhotos.shp).

Gaps in sequential SEABOSS station numbers may exist. Completeness_Report: A total of 184 sampling sites were occupied during survey 07003 covering both the Duxbury to Hull and Cape Cod Bay survey areas. Only the 109 sampling sites within Cape Cod Bay survey area are included in this spatial dataset. The SEABOSS video tracklines that are not included in this report are from sites north of Brant Rock, Massachusetts and have been published in a previous data release (Barnhardt and other 2010) focused on the Duxbury to Hull survey area. The length of the trackline represents the distance along the drift that the bottom was in view on the monitor aboard the ship. Video may not have been recorded at each station or for the full duration of the SEABOSS drift. The tracklines do not represent video of the water column during deployment or retrieval. Stations represented by SEABOSS tracklines 41-60 and 71-76 were rapid deployment sites where no video was collected. Only bottom photographs and sediment samples (when possible) were collected at these sites. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigation for survey 07003 used differential Global Positioning System (GPS). The recorded position of each node along the SEABOSS trackline 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 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 trackline is 20-30 meters.
