Investigations of coastal change and coastal resources often require continuous elevation profiles from the seafloor to coastal terrestrial landscapes. Differences in elevation data collection in the terrestrial and marine environments result in separate elevation products that may not share a vertical datum. This data release contains the assimilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S., focused on the coastal interface. All datasets were converted to a consistent horizontal datum, the North American Datum of 1983, but the native vertical datum for...

OBIS-USA brings together marine biological occurrence data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. Waters or with U.S. funding. Coordinated by the Core Science, Analytics, Synthesis, and Libraries (CSAS&L) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biogeographic Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization International Oceanographic...

Species occurrence records of the taxonomic class of Bivalvia in oceans within 1000 kilometers of the United States shoreline. This is a subset of the OBIS-USA dataset where Bivalvia records were queried on December 2, 2014. After initial queries, the remaining data were further queried to retain only samples within 1000 kilometers of the U.S. shoreline. Spatial queries were then used to remove samples overlaying land masses. Data are provided in a geodatabase format, as well as a comma seperated values format. OBIS-USA provides aggregated, interoperable biogeographic data collected primarily from U.S. waters and oceanic regions--the Arctic, the Atlantic and Pacific oceans, the Caribbean Sea, Gulf of Mexico and...

NOTE - This map contains two datasets: "Important Anadromous Fish Habitat, Northeast U.S." and "Atlantic Salmon Rearing Areas, Maine"These dataset are part of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. "Important Anadromous Fish Habitat" and “Atlantic Salmon Rearing Areas, Maine” are two input used in developing “Lotic Core Areas, Stratified by Watershed, Northeast U.S.” that is also part of Nature’s Network. Lotic core areas represent intact, well-connected rivers and stream reaches in...

This data set contains the sea floor topographic contours,sun-illuminated topographic imagery, and backscatterintensity generated from a multibeam sonar survey of theStellwagen Bank National Marine Sanctuary region off Boston,Massachusetts, an area of approximately 1100 square nauticalmiles. The Stellwagen Bank NMS Mapping Project is designed toprovide detailed maps of the Stellwagen Bank region'senvironments and habitats and the first complete multibeamtopographic and sea floor characterization maps of asignificant region of the shallow EEZ.Data were collected on four cruises over atwo year period from the fall of 1994 to the fall of 1996.The surveys were conducted aboard the Candian HydrographicService vessel...

Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes. The area is divided into the following four geographical areas to reduce file size and facilitate publishing: Massachusetts Bay from the Massachusetts-New Hampshire border south to Provincetown and Scituate and east to Stellwagen Bank; Cape Cod Bay from Provincetown to Scituate and south to Hyannis; Buzzards Bay from the Cape Cod Canal southwest to the State border including the Elizabeth Islands and extending north to Fall River and Mount Hope Bay; and Nantucket and Vineyard Sounds, from Hyannis south...

The NFHAP Coastal Spatial Framework and Indicator Datasets consist of a geospatial base layer developed in ArcGIS, and associated data fields joined to the spatial framework. The Coastal Spatial Framework is a layer of 612 distinct polygons covering coastal areas of the Continental U.S. Polygons represent either coastal watersheds (land) or coastal waters (estuaries, inshore marine, offshore marine),and are classified into six regions and 22 nested subregions. Each polygon is assigned a unique code (UniqueID) to provide location reference for indicator data, and enable joins to separate data tables.s for information recorded in the Bibliography and Assessment tables. Key indicator data fields attributed to each...

Strong indicators of species’ sensitivity, adaptive capacity, and overall vulnerability to climate change are provided by changes in phenology, the timing of recurring life events (Parmesan and Yohe, 2003). We possess poor information on climate induced shifts in phenology of marine organisms, especially top predators. The Gulf of Maine (GOM) Seasonal Migrants Project is an ongoing effort to determine the phenological changes occurring in the GOM across marine mammals, sea turtles, and other marine species of conservation concern. As part of that study, stranding data of injured or dead animals was explored for its utility to serve as supplemental data to amend more traditional survey data where observations are...

These data include species occurrence records of fish in oceans within 1000 kilometers of the United States shoreline. This dataset is a subset of the OBIS-USA dataset as of December 2, 2014 and includes records of the taxonomic groups of Actinopterygii, Chondrichthyes, Myxini, Osteichthyes, and Petromyzontida. After initial taxonomic queries, the remaining data were further queried to retain only samples within 1000 kilometers of the U.S. shoreline. Spatial queries were then used to remove samples overlaying land masses. Data are provided in a geodatabase format, as well as a comma seperated values format.

The sampling of the riverine-to-marine transect (Penobscot River, Penobscot Bay, and the Gulf of Maine) took place in 2008. Water samples were collected and filtered in the field using 0.45 micrometer capsule filters (Versapor membrane), silicon tubing, and a peristaltic pump. Water samples were then shipped on ice to the U.S. Geological Survey in Boulder, Colorado and chilled to approximately 4 degrees Celsius until analysis. Dissolved organic matter (DOM) was separated into fractions by an isolation method that passes aqueous sample through Amberlite XAD8 and XAD4 resins using low pressure liquid chromatography. The hydrophobic organic acid (HPOA) fraction is the eluate from the XAD8 fractionation column and the...
