Summary
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. To address these concerns the U.S. Geological Survey, in cooperation with the Massachusetts Office of Coastal Zone Management (CZM), comprehensively mapped the Cape Cod Bay sea floor to characterize the surface and shallow subsurface geologic framework. Geophysical data collected include swath bathymetry, backscatter, and seismic reflection profile data. Ground-truth data, including sediment samples, underwater video, and bottom photographs were also collected. This effort is part of a long-term collaboration between the USGS and the Commonwealth of Massachusetts to map the State's waters, support research on the Quaternary evolution of coastal Massachusetts, the influence of sea-level change and sediment supply on coastal evolution, and efforts to understand the type, distribution, and quality of subtidal marine habitats. This collaboration produces high-resolution geologic maps and Geographic Information System (GIS) data that serve the needs of research, management and the public. Data collected as part of this mapping cooperative continue to be released in a series of USGS Open-File Reports and Data Releases

Sound velocity profile data from an AML Oceanographic MVP30 and Minos X collected in Cape Cod Bay, Massachusetts during USGS Field Activity 2019-002-FA (PNG images, SVP text, and point shapefile, GCS WGS 84)
This dataset is used to display the locations of sound velocity profiles collected with an AML MVP30 (moving vessel profiler) and an AML Minos X SVP (sound velocity profiler) during survey 2019-002-FA in Cape Cod Bay, Massachusetts. The information contained within the sound velocity profiles is needed to account for refraction artifacts that may be present within raw swath bathymetric data. This dataset contains graphs of the sound velocity profile at each station location, as well as location in Geographic Coordinate System (GCS) WGS 84 latitude and longitude, time of day and date of collection.

Seismic Data
-
Multichannel seismic-reflection and navigation data collected using an Applied Acoustics S-Boom and a Geometrics GeoEel digital 32-channel streamer during USGS field activity 2019-002-FA (point and polyline shapefiles, CSV text, PNG Images, and SEG-Y data, GCS WGS 84).
This dataset contains common mid-point (CMP) and trackline navigation, profile images, and raw SEG-Y trace data for approximately 580 km of multichannel seismic-reflection data collected by the U.S. Geological Survey during USGS field activity 2019-002-FA in Cape Cod Bay. Images of each seismic profile were generated in order to provide portable and easily viewable alternatives to the SEG-Y versions of the data. Each profile image can be hyperlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2019-002-FA_MCS_cmpTracklines.shp'. CMP and tick marks along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile '2019-002-FA_MCS_cmp500.shp'. This information allows for spatial correlation of MCS seismic-reflection profiles images with other geophysical and sample data for investigating sea-floor morphology and stratigraphy in the area. An additional single MCS profile from a pre-cruise equipment testing survey (2019-014-FA) is also included with this dataset.

Geotagged sea-floor images and locations of bottom images collected in Cape Cod Bay, Massachusetts, in September 2019 by the U.S. Geological Survey during field activity 2019-034-FA (JPEG images, point shapefile, and CSV file; GCS WGS 84)
This dataset provides the geotagged sea-floor images as well as the location of those images acquired with a GoPro HERO4 Black camera and SeaViewer 6000 HD Sea-Drop video camera on the Mini SEABed Observation and Sampling System (MiniSEABOSS) aboard the Research Vessel (R/V) Tioga during USGS field activity 2019-034-FA (September 17 and 19, 2019). These data were collected to characterize the sea floor by identifying sediment texture and to ground-truth acoustic data collected during USGS field activity 2019-002-FA. Bottom images serve as a means to visually classify grain size and identify sea-floor habitats, and they are especially important for sample sites where no physical sediment sample was collected.

Locations and grain-size analysis results of sediment samples collected in Cape Cod Bay, Massachusetts, in September 2019 by the U.S. Geological Survey during field activity 2019-034-FA (point shapefile and CSV file, GCS WGS 84, MLLW vertical datum)
This dataset provides access to the locations and grain-size analysis results of surficial sediments collected with a modified Van Veen grab sampler on the Mini SEABed Observation and Sampling System (MiniSEABOSS) aboard the Research Vessel (R/V) Tioga during USGS field activity 2019-034-FA (September 17 and 19, 2019). The sediments were analyzed using the Beckman Coulter Multisizer 3 and sieving of the >= 4-phi fraction. These data were collected to characterize the sea floor by identifying sediment texture and to ground-truth acoustic data collected during USGS field activity 2019-002-FA.

Revision History
First release: 2022
Revised: September 2022 (ver. 2.0)
Changes in Version 2.0
1) An existing dataset was modified: "Multibeam bathymetric data collected in Cape Cod Bay, Massachusetts during USGS Field Activity 2019-002-FA, using a dual-head Reson T20-P multibeam echo sounder (32-bit GeoTIFF, UTM Zone 19N, NAD 83, MLLW Vertical Datum, 5-m resolution)" had erroneous interpolation applied to the final bathymetry raster. These data were corrected and an additional process step was added to the metadata file to describe the change as well as document the revision and update the larger work citation. The revised GeoTIFF and associated metadata file have the same filenames as the originally published dataset.
