This report presents high-resolution maps 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 (fig. 1.1). The maps were prepared as part of a cooperative mapping program between the U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management (CZM). They are based on marine geophysical data, sediment sampling, and bottom photography obtained on two research cruises carried out in 2003 and 2004. The primary objective of this program is to develop a suite of seafloor maps that provide geologic information for management of coastal and marine resources. Accurate maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine reserves, and assessing environmental changes due to natural or human impacts. The maps also provide a geologic framework for scientific research, industry and the public.
The organization of this report is outlined in the navigation bar along the left-hand margin of the page. This is section 1, the introduction. Section 2 briefly describes the mapping products contained in this report and has links to large-format map sheets, that can be viewed on line or downloaded. Section 3 is a description of the data collection, processing, and analysis procedures used to create the map products. Section 4 examines the geologic framework and late Quaternary evolution of the region, and presents two different strategies for mapping the complex seafloor. This report also contains four appendices that include GIS layers of all data collected in this study, and copies of the sample and photographic data used to validate the interpretations.

S. Geological Survey (USGS) has collected a large amount of surficial and shallow subsurface geologic information in the deep-water parts of the US EEZ in the northern Gulf of Mexico. These data include digital sidescan sonar imagery, digital seismic-reflection data, and descriptions and analyses of piston and gravity cores. The data were collected during several different projects that addressed surficial and shallow subsurface geologic processes. Some of these datasets have already been published, but the growing interest in the occurrence and distribution of gas hydrates in the Gulf of Mexico warrants integrating these existing USGS datasets and associated interpretations into a Geographic Information System (GIS) to provide regional background information for ongoing and future gas hydrate research.
This GIS is organized into five different components that contain (1) information needed to develop an assessment of gas hydrates, (2) background information for the Gulf of Mexico, (3) cores collected by the USGS, (4) seismic surveys conducted by the USGS, and (5) sidescan sonar surveys conducted by the USGS. A brief summary of the goals and findings of the USGS field programs in the Gulf of Mexico is given in the Geologic Findings section, and then the contents of each of the five data categories are described in greater detail in the GIS Data Catalog section.

Direct implementation of point-to-point transformation with appropriate functions yields the variety of projections available in commercial software packages, but implementation with data other than points requires specific adaptation of the transformation equations or prior preparation of the data to allow the transformation to succeed. It seems that some of these packages use the U.S. Geological Survey's (USGS) General Cartographic Transformation Package (GCTP) or similar point transformations without adaptation to the specific characteristics of raster data (Usery and others, 2003a).\r\n\r\nUsery and others (2003b) compiled and tabulated the accuracy of categorical areas in projected raster datasets of global extent. Based on the shortcomings identified in these studies, geographers and applications programmers at the USGS expanded and evolved a USGS software package, MapIMG, for raster map projection transformation (Finn and Trent, 2004). Daniel R. Steinwand of Science Applications International Corporation, National Center for Earth Resources Observation and Science, originally developed MapIMG for the USGS, basing it on GCTP. Through previous and continuing efforts at the USGS' National Geospatial Technical Operations Center, this program has been transformed from an application based on command line input into a software package based on a graphical user interface for Windows, Linux, and other UNIX machines.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20061016","usgsCitation":"Finn, M.P., Trent, J.R., and Buehler, R.A., 2006, User's Guide for MapIMG 2: Map Image Re-projection Software Package (Supersedes OFR 2003-433): U.S. Geological Survey Open-File Report 2006-1016, 21 p., https://doi.org/10.3133/ofr20061016.","productDescription":"21 p.","numberOfPages":"21","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":194755,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10633,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://carto-research.er.usgs.gov/projection/pdf/mapimg2UG.pdf","size":"299","linkFileType":{"id":1,"text":"pdf"}}],"edition":"Supersedes OFR 2003-433","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adae4b07f02db68568a","contributors":{"authors":[{"text":"Finn, Michael P. 0000-0003-0415-2194 mfinn@usgs.gov","orcid":"https://orcid.org/0000-0003-0415-2194","contributorId":2657,"corporation":false,"usgs":true,"family":"Finn","given":"Michael","email":"mfinn@usgs.gov","middleInitial":"P.","affiliations":[{"id":5047,"text":"NGTOC Denver","active":true,"usgs":true},{"id":5074,"text":"Center for Geospatial Information Science (CEGIS)","active":true,"usgs":true}],"preferred":true,"id":287122,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Trent, Jason R.","contributorId":81187,"corporation":false,"usgs":true,"family":"Trent","given":"Jason","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":287123,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Buehler, Robert A.","contributorId":92369,"corporation":false,"usgs":true,"family":"Buehler","given":"Robert","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":287124,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":76273,"text":"ofr20061002 - 2006 - The 20th-Century Topographic Survey as Source Data for Long-Term Landscape Studies at Local and Regional Scales","interactions":[],"lastModifiedDate":"2012-04-15T17:28:15","indexId":"ofr20061002","displayToPublicDate":"2006-03-30T00:00:00","publicationYear":"2006","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2006-1002","title":"The 20th-Century Topographic Survey as Source Data for Long-Term Landscape Studies at Local and Regional Scales","docAbstract":"Historical topographic maps are the only systematically collected data resource covering the entire nation for long-term landscape change studies over the 20th century for geographical and environmental research.

These coal districts include: (1) Catanduanes (Eocene); (2) Cebu, Zamboanga Sibuguey, Bukidnon, Maguindanao, Sarangani, and Surigao (Oligocene to Miocene); (3) Batan Island, Masbate, Semirara (including Mindoro), and Quezon-Polilio (lower-upper Miocene); (4) Davao, Negros, and Sorsogon (middle-upper Miocene); (5) Cotabato (lower Miocene-lower Pliocene), Cagayan-Isabella, and Quirino (upper Miocene-Pliocene); (6) Sultan Kudarat (upper Miocene-Pleistocene); and (7) Samar-Leyte (lower Pliocene-Pleistocene). In general, coal rank is directly related to the age of the deposits - for example, the Eocene coal is semi-anthracite and the Pliocene-Pleistocene coal is lignite.\r\n\r\nTotal coal resources in these 19 coal districts, which are compiled by the Geothermal and Coal Resources Development Division (GCRDD) of the Department of Energy of the Philippines, are estimated at a minimum of 2,268.4 million metric tonnes (MMT) (approximately 2.3 billion metric tones). The largest resource (550 MMT) is the subbituminous coal in the Semirara (including Mindoro) coal district, and the smallest (0.7 MMT) is the lignite-subbituminous coal in the Quirino coal district. The combined lignite and subbituminous coal resources, using the classification by GCRDD and including Semirara and Surigao coal districts, are about 1,899.2 MMT, which make up about 84 percent of the total coal resources of the Philippines. The remaining resources are composed of bituminous and semi-anthracite coal.\r\n\r\nThe subbituminous coal of Semirara Island in the Mindoro-\r\nSemirara coal district (fig. 2) is known to contain coalbed\r\nmethane (CBM), with the coal being comparable in gas content and adsorption isotherms to the coal of the Paleocene Fort Union Formation in the Powder River Basin in Wyoming, USA (Flores and others, 2005). As a consequence, the presence of CBM in the Semirara coal led to the present study of determining the adsorption isotherms, or gas (CBM) holding or storage capacity, of coal beds of various ages from selected coal districts in the Philippines. Samples for the study were collected\r\nfrom the Batan Island, Catanduanes, Cagayan-Isabella, Cebu, Negros, Samar, Semirara, Cotabato, Surigao, and Malangas coalfield of the Zamboanga Sibuguey coal districts by five field geology teams from the GCRDD.","language":"ENGLISH","doi":"10.3133/ofr20061063","usgsCitation":"Flores, R.M., Stricker, G.D., Papasin, R.F., Pendon, R.R., del Rosario, R.A., Malapitan, R.T., Pastor, M.S., Altomea, E.A., Cuaresma, F., Malapitan, A.S., Mortos, B.R., and Tilos, E.N., 2006, The Republic of the Philippines coalbed methane assessment: based on seventeen high pressure methane adsorption isotherms (Online only, Version 1.0): U.S. Geological Survey Open-File Report 2006-1063, 70 p., https://doi.org/10.3133/ofr20061063.","productDescription":"70 p.","numberOfPages":"70","onlineOnly":"Y","costCenters":[],"links":[{"id":194896,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":7082,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2006/1063/","linkFileType":{"id":5,"text":"html"}}],"edition":"Online only, Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67acb4","contributors":{"authors":[{"text":"Flores, Romeo M. rflores@usgs.gov","contributorId":71984,"corporation":false,"usgs":true,"family":"Flores","given":"Romeo","email":"rflores@usgs.gov","middleInitial":"M.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":286994,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stricker, Gary D. gstricker@usgs.gov","contributorId":87163,"corporation":false,"usgs":true,"family":"Stricker","given":"Gary","email":"gstricker@usgs.gov","middleInitial":"D.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":286997,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Papasin, Ramon F.","contributorId":95164,"corporation":false,"usgs":true,"family":"Papasin","given":"Ramon","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":286999,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pendon, Ronaldo R.","contributorId":96377,"corporation":false,"usgs":true,"family":"Pendon","given":"Ronaldo","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":287000,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"del Rosario, Rogelio A.","contributorId":47043,"corporation":false,"usgs":true,"family":"del Rosario","given":"Rogelio","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":286992,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Malapitan, Ruel T.","contributorId":77621,"corporation":false,"usgs":true,"family":"Malapitan","given":"Ruel","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":286995,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Pastor, Michael S.","contributorId":13710,"corporation":false,"usgs":true,"family":"Pastor","given":"Michael","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":286990,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Altomea, Elmer A.","contributorId":31854,"corporation":false,"usgs":true,"family":"Altomea","given":"Elmer","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":286991,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Cuaresma, Federico","contributorId":78428,"corporation":false,"usgs":true,"family":"Cuaresma","given":"Federico","email":"","affiliations":[],"preferred":false,"id":286996,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Malapitan, Armando S.","contributorId":105815,"corporation":false,"usgs":true,"family":"Malapitan","given":"Armando","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":287001,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Mortos, Benjamin R.","contributorId":60732,"corporation":false,"usgs":true,"family":"Mortos","given":"Benjamin","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":286993,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Tilos, Elizabeth N.","contributorId":89997,"corporation":false,"usgs":true,"family":"Tilos","given":"Elizabeth","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":286998,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}} ,{"id":75863,"text":"ofr20061070 -

Although most mining activity ceased by the 1990s, the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S. Geological Survey identified ground-water discharge as a significant pathway for the loading of metals to surface water from both acid-mine drainage and acid-rock drainage. In an effort to understand the ground-water flow system in the upper Animas River watershed, Prospect Gulch was selected for further study because of the amount of previous data provided in and around that particular watershed. In support of this ground-water research effort, wells and piezometers were installed to allow for coring during installation, subsurface hydrologic testing, and the monitoring of ground-water hydraulic heads and geochemistry. This report summarizes the data that were collected during and after the installation of these wells and piezometers and includes (1) subsurface completion details, (2) locations and elevations, (3) geologic logs and elemental data, (4) slug test data for the estimation of subsurface hydraulic conductives, and (5) hydraulic head data.","language":"ENGLISH","doi":"10.3133/ofr20061030","usgsCitation":"Johnson, R.H., and Yager, D.B., 2006, Completion reports, core logs, and hydrogeologic data from wells and piezometers in Prospect Gulch, San Juan County, Colorado (Version 1.01): U.S. Geological Survey Open-File Report 2006-1030, v, 32 p.; data files, https://doi.org/10.3133/ofr20061030.","productDescription":"v, 32 p.; data files","numberOfPages":"37","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[],"links":[{"id":194853,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":7040,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2006/1030/","linkFileType":{"id":5,"text":"html"}},{"id":8046,"rank":9999,"type":{"id":2,"text":"Additional Report Piece"},"url":"https://pubs.usgs.gov/of/2006/1030/downloads/","linkFileType":{"id":5,"text":"html"}}],"scale":"0","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -107.83416666666666,37.75 ], [ -107.83416666666666,37.96666666666667 ], [ -107.5,37.96666666666667 ], [ -107.5,37.75 ], [ -107.83416666666666,37.75 ] ] ] } } ] }","edition":"Version 1.01","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a82c9","contributors":{"authors":[{"text":"Johnson, Raymond H. rhjohnso@usgs.gov","contributorId":707,"corporation":false,"usgs":true,"family":"Johnson","given":"Raymond","email":"rhjohnso@usgs.gov","middleInitial":"H.","affiliations":[],"preferred":true,"id":286978,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yager, Douglas B. 0000-0001-5074-4022 dyager@usgs.gov","orcid":"https://orcid.org/0000-0001-5074-4022","contributorId":798,"corporation":false,"usgs":true,"family":"Yager","given":"Douglas","email":"dyager@usgs.gov","middleInitial":"B.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":286979,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":75843,"text":"ofr20061027 - 2006 - Concepts and procedures required for successful reduction of tensor magnetic gradiometer data obtained from an unexploded ordnance detection demonstration at Yuma Proving Grounds, Arizona","interactions":[],"lastModifiedDate":"2012-02-02T00:14:20","indexId":"ofr20061027","displayToPublicDate":"2006-03-26T00:00:00","publicationYear":"2006","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2006-1027","title":"Concepts and procedures required for successful reduction of tensor magnetic gradiometer data obtained from an unexploded ordnance detection demonstration at Yuma Proving Grounds, Arizona","docAbstract":"On March 12, 2003, data were gathered at Yuma Proving Grounds, in Arizona, using a Tensor Magnetic Gradiometer System (TMGS). This report shows how these data were processed and explains concepts required for successful TMGS data reduction. Important concepts discussed include extreme attitudinal sensitivity of vector measurements, low attitudinal sensitivity of gradient measurements, leakage of the common-mode field into gradient measurements, consequences of thermal drift, and effects of field curvature. Spatial-data collection procedures and a spin-calibration method are addressed. Discussions of data-reduction procedures include tracking of axial data by mathematically matching transfer functions among the axes, derivation and application of calibration coefficients, calculation of sensor-pair gradients, thermal-drift corrections, and gradient collocation. For presentation, the magnetic tensor at each data station is converted to a scalar quantity, the I2 tensor invariant, which is easily found by calculating the determinant of the tensor. At important processing junctures, the determinants for all stations in the mapped area are shown in shaded relief map-view. Final processed results are compared to a mathematical model to show the validity of the assumptions made during processing and the reasonableness of the ultimate answer obtained.","language":"ENGLISH","doi":"10.3133/ofr20061027","usgsCitation":"Bracken, R.E., and Brown, P.J., 2006, Concepts and procedures required for successful reduction of tensor magnetic gradiometer data obtained from an unexploded ordnance detection demonstration at Yuma Proving Grounds, Arizona (Online only, Version 1.0): U.S. Geological Survey Open-File Report 2006-1027, 53 p., https://doi.org/10.3133/ofr20061027.","productDescription":"53 p.","numberOfPages":"53","onlineOnly":"Y","costCenters":[],"links":[{"id":194854,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":7041,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2006/1027/","linkFileType":{"id":5,"text":"html"}}],"edition":"Online only, Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a487d","contributors":{"authors":[{"text":"Bracken, Robert E. 0000-0001-7759-2743 rbracken@usgs.gov","orcid":"https://orcid.org/0000-0001-7759-2743","contributorId":2640,"corporation":false,"usgs":true,"family":"Bracken","given":"Robert","email":"rbracken@usgs.gov","middleInitial":"E.","affiliations":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":286980,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brown, Philip J.

The density and gravity modeling indicates that CP basin is a shallow, oval-shaped basin which trends north-northeast and contains ~800 m of basin-filling rocks and sediment at its deepest point in the northeast. CP basin is separated from the deeper Frenchman Flat basin by a subsurface ridge that may represent a Tertiary erosion surface at the top of the Paleozoic strata. The magnetic modeling indicates that the Cane Spring fault appears to merge with faults in northwest Massachusetts Mountain, rather than cut through to Yucca Flat basin and that the basin is downed-dropped relative to Massachusetts Mountain.\r\n\r\nThe magnetic modeling indicates volcanic units within Yucca Flat basin are down-dropped on the west and supports the interpretations of Phelps and KcKee (1999). The magnetic data indicate that the only faults that appear to be through-going from Yucca Flat into either Frenchman Flat or CP basin are the faults that bound the CP hogback. In general, the north-trending faults present along the length of Yucca Flat bend, merge, and disappear before reaching CP hogback and Massachusetts Mountain or French Peak.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20051367","collaboration":"Prepared in cooperation with the U.

The geology of these deposits within the Newark Bedrock Valley is complex, however, and a detailed investigation of their water bearing and transmitting properties will be required to successfully locate high-capacity wells.
Volatile organic compounds, pesticides, and cyanide were not detected in ground water during this investigation. Metals and nitrogen compounds were not detected at concentrations above their Maximum Contaminant Level. Iron, manganese, and aluminum were detected at concentrations above their Secondary Maximum Con-taminant Level and various constituents were detected at concentrations above background levels downgradient of the landfill. Nitrate and ammonia, presumably derived from agricultural practices, also were detected in samples from locations hydraulically upgradient of the landfill.
Oxidation-reduction conditions in the aquifer become more reducing with depth. This change is reflected by a change in the type of nitrogen compound detected and the concentration of dissolved oxygen and iron in the glacial drift aquifer. Concentrations of some of the major ions and metals may be affected by dissolution of carbonate minerals in the aquifer and perhaps road salts.
