 Sea-Floor Character and Sedimentary Processes in the Vicinity of Woods Hole, Massachusetts; 2008, U.S. Geological Survey Open-File Report 2008-1004 |
The digital terrain models (DTMs), imagery, interpretive data layers, and data presented herein were derived from multibeam echo-sounder and sidescan-sonar data collected in the vicinity of Woods Hole, the main passage between Buzzards Bay and Vineyard Sound, Massachusetts, and from the stations occupied to verify these acoustic data (fig. 1). Basic data layers show sea-floor topography, sun-illuminated shaded relief, and backscatter intensity; interpretive layers show the distributions of surficial sediment, sedimentary environments, and sea-floor features. Presented verification data include sediment grain-size analyses and a gallery of still photographs of the seabed.
This publication is the fourth in a series of digital reports describing the sea-floor geology around Cape Cod. The first focused on the area off the eastern shore of the outer Cape (Poppe and others, 2006); the second on Quicks Hole, another passage through the Elizabeth Islands (Poppe and others, 2007a); and the third on Great Round Shoal Channel at the eastern entrance to Nantucket Sound (Poppe and others, 2007b). |
| Sidescan-Sonar Imagery and Surficial Geologic Interpretations of the Sea Floor in Central Rhode Island Sound; 2008, U.S. Geological Survey Open-File Report 2007-1366 |
The U.S. Geological Survey (USGS) has been working with the National Oceanic and Atmospheric Administration (NOAA) to interpret the surficial geology of areas along the northeastern coast of the United States. During 2004, the NOAA Ship RUDE conducted Hydrographic Survey H11321 in Rhode Island Sound. This sidescan-sonar and bathymetry survey covers an area of 93 km² located 12 km southeast of Brenton Point, RI in water depths of 28-39 m (fig. 1). The purpose of this report is to delineate sea floor features and sedimentary environments of this area in central Rhode Island Sound using sidescan-sonar and bathymetric data from NOAA Survey H11321 and seismic-reflection data from a previous USGS field study (Needell and others, 1983a). |
| Sea-Floor Character and Sedimentary Processes of Great Round Shoal Channel, Offshore Massachusetts; 2007, U.S. Geological Survey Open-File Report 2007-1138 |
During 2004 the National Oceanic and Atmospheric Administration (NOAA) Ship THOMAS JEFFERSON completed a hydrographic survey (H11079) that covered a roughly 33.9 square km area of Great Round Shoal Channel, located at the eastern entrance to Nantucket Sound. This digital publication contains bathymetric grids and GeoTIFF images generated from the multibeam data, sidescan-sonar imagery, bottom photographs, textural data, and an interpretion of the surficial geology. |
| Sidescan-Sonar Imagery, Multibeam Bathymetry, and Surficial Geologic Interpretations of the Sea Floor in Rhode Island Sound, off Sakonnet Point, Rhode Island; 2007, U.S. Geological Survey Open-File Report 2007-1150 |
The U.S. Geological Survey (USGS) is working with the National Oceanic and Atmospheric Administration (NOAA) to interpret the surficial geology in estuaries and sounds along the northeastern coast of the United States. This report interprets the area covered in 2004 by NOAA Survey H11320, about 72 km² of sea floor in eastern Rhode Island Sound (RIS), located about 8 km south of Sakonnet Point, Rhode Island. This DVD-ROM contains digital versions of the sidescan and bathymetric imagery and interpretive data layers and maps showing distributions of surficial features and sedimentary environments.
The imagery and its interpretations are provided to help define the geological variability of the sea floor, improve our understanding of surficial processes, and provide a detailed framework for future research, monitoring, and management activities. |
| Sea-Floor Character and Surface Processes in the Vicinity of Quicks Hole, Elizabeth Islands, Massachusetts; 2007, U.S. Geological Survey Open-File Report 2006-1357 |
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. The imagery, interpretive data layers, and data presented within this Open-File Report were derived from multibeam echo-sounder and sidescan sonar surveys conducted by NOAA survey H11076 in the vicinity of Quicks Hole, a passage through the Elizabeth Islands, which extend in a chain southwest off Cape Cod, Massachusetts, and from the stations occupied by the USGS to verify these acoustic data. Although originally collected for charting purposes, these data provide a fundamental framework for research and management activities along this part of the Massachusetts coastline, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. |
| A GIS Library of Multibeam Data for Massachusetts Bay and the Stellwagen Bank National Marine Sanctuary, Offshore of Boston, Massachusetts; 2007, U.S. Geological Survey Data Series 99 |
The U.S. Geological Survey (USGS) has mapped the sea floor of the Stellwagen Bank National Marine Sanctuary and western Massachusetts Bay, offshore of Boston, Massachusetts. The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick. This GIS Library contains images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys. |
| High-Resolution Geologic Mapping of the Inner Continental Shelf: Boston Harbor and Approaches, Massachusetts; 2006, U.S. Geological Survey Open-File Report 2006-1008, 1 DVD-ROM. |
This report presents the surficial geologic framework data and information for the sea floor of Boston Harbor and Approaches, Massachusetts. Included in this report is the geospatial data used to create the high-resolution maps of the sea floor and a gallery of photographs of the sea floor. |
| High-Resolution Geologic Mapping of the Inner Continental Shelf: Nahant to Gloucester, Massachusetts; 2006, U.S. Geological Survey Open-File Report 2005-1293 |
This report presents high-resolution geologic maps and geospatial data of the seafloor offshore of Massachusetts, from Nahant to Gloucester. Approximately 134 km² of the inner shelf were mapped with a focus on the nearshore region in water depths less than 40 m. Data layers include distribution of bottom types, sediment thickness and location and links to acquired bottom photographs. |
| Geological Interpretation of Bathymetric and Backscatter Imagery of the Sea Floor Off Eastern Cape Cod, Massachusetts; 2006, U.S. Geological Survey Open-File Report 2005-1048, 1 DVD-ROM. |
