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 (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 is the spatial dataset for the Red Brook Harbor survey area within Buzzards Bay, Massachusetts. These data are the results of a high-resolution geophysical (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples and bottom photographs) survey, conducted in 2009.
In addition to inclusion within the USGS-CZM geologic mapping effort, these Red Brook Harbor data will be used to assess the shallow-water mapping capability of the geophysical systems deployed for this project, with an emphasis on identifying resolution benchmarks for the interferometric sonar system. (<http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-018-FA>)
Purpose:
This data set includes the locations, identifiers, grain-size data, and textural descriptions of surficial sediments collected at 41 sample stations in Red Brook Harbor, MA, during USGS survey 09018. Sediment sampling was conducted November 16th and 17th, 2009, aboard the R/V Rafael. Samples were collected with a modified Van Veen grab device (the USGS Mini-SEABed Observation and Sampling System (Mini SEABOSS)). This dataset was collected to ground-truth (verify) the acoustic datasets that were acquired in Red Brook Harbor. Samples were analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: All attributes were checked in a consistent manner.
Logical_Consistency_Report: Gaps in sequential sample numbers may exist.
Completeness_Report:
Sediment samples were collected at 41 of the 48 planned sampling sites within the Red Brook Harbor survey area. Samples were not collected in areas where real-time video and photography indicated the sea bed composition might damage the sampling equipment. Samples were collected with the USGS Mini-SEABOSS.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal positions for sediment samples were provided by a Differential Global Positioning System (DGPS) with an estimated accuracy of ± 2 meters. However, the recorded position of each sediment sample is actually the position of the DGPS antenna on the survey vessel, not the Mini-SEABOSS sampler. The Mini-SEABOSS was deployed approximately 5 meters astern of the DGPS antenna, off the starboard side of the R/V Rafael. In addition to this 5-meter offset, currents may have caused the Mini-SEABOSS to drift horizontally from the survey vessel. Based on the various horizontal offsets, a conservative estimate for the horizontal accuracy of the Mini-SEABOSS locations for the Red Brook Harbor survey is 10-15 meters.

Source_Contribution:
Sediment samples were collected with the USGS Mini-SEABOSS sampling device equipped with a Van Veen grab sampler in areas where the sea floor composition permitted sampling without damaging equipment. Half of the 48 planned sample locations were chosen based on interferometric sonar backscatter intensity values, with a focus on collecting samples in areas of transition between high and low backscatter, and areas of homogeneous backscatter. The remaining 24 sample locations were chosen by a randomized GIS routine. In addition to being used for ground-truthing the Red Brook Harbor geophysical data, these random sediment samples will be used in future habitat modeling efforts.

The HYPACK target file (with eastings and northings) was added to ArcMap v9.3 as an event theme (Tools/Add XY Data, UTM, Zone 19, WGS84), and then converted to a shapefile. Planned sample sites where the sea floor composition prohibited collecting a sample are not included in this dataset.

Samples were analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. Coarse fraction determined by sieve; fine fraction determined by Coulter Counter. See Poppe, Williams, and Paskevich (2005) for analytical specifics. The sediment analyses were returned from the lab as a Microsoft Excel file (XLS).

Overview_Description:
Entity_and_Attribute_Overview:
The Attribute Definition Source for most of these attributes is the USGS East Coast Sediment Texture Database data dictionary which can be found in USGS Open File Report 2005-1001 (<https://pubs.usgs.gov/of/2005/1001/>). The following seven fields in the attribute table are not populated with values: MODE1CLASS, MODE1FREQ, MODE2CLASS, MODE2FREQ, MODE3CLASS, MODE3FREQ, and NMODES. These fields were utilized in previous versions of the USGS sediment analysis process, but were not utilized in the sediment sample analysis for this project.
