Discover and access data, information, and decision tools related to our ocean, coasts, and Great Lakes. The National Ocean Council provides this site to support regional marine planning efforts across the country and to create a convenient place for anyone to find out more about our marine, coastal, and Great Lakes environments.

The oceanographic processes that disturb the continental shelf include the actions of surface waves, internal waves, and currents (tidal, density, wave-driven, wind-driven, and geostrophic). Because the North Pacific Ocean can generate extremely large surface waves that yield relatively high near-bed wave orbital velocities, wave-generated near-bed currents are often considered to be the dominant mechanism for seabed disturbances along the California coast (Sherwood and others, 1994; Storlazzi and Jaffe, 2002; Storlazzi and others, 2003). In this...

This web site describes the Pacific Coastal and Marine Science Center Project titled, "The Impact of Sea-Level Rise and Climate Change on Pacific Ocean Atolls that House Department of Defense Installations." The study itself is a collaboration between the U.S. Geological Survey (USGS), the National Oceanographic and Atmospheric Administration (NOAA), Deltares (an applied research institute in the Netherlands), and the University of Hawaii (UH). The goals of this study are to: 1.) provide basic understanding...

In freshwater bodies of New Hampshire, the most problematic aquatic invasive plant species is Myriophyllum heterophyllum or variable leaf water-milfoil. Once established, variable leaf water-milfoil forms dense beds that can alter the limnologic characteristics of a waterbody, impacting natural lacustrine communities and their habitats. Variable leaf water-milfoil infestations also disrupt recreational uses of waterbodies and have negatively affected swimming, boating, fishing, and property values in and around several lakes and ponds in New Hampshire. In...

This data product contains avian habitat data collected on the Seward Peninsula, Alaska, USA, during 21 May ? 10 June 2012. We conducted replicated 10-min surveys at 111 points located along 9 transects occurring over gradients of physical and biotic habitat conditions and recorded observations of individual birds identified to species. Survey points, or sites, were located approximately 500 m apart and observations of birds were limited to a maximum distance of 250 m to...

Water analyses are reported for 371 water samples collected from numerous thermal and non-thermal features in Yellowstone National Park (YNP) during 2009?2013. Water samples were collected and analyzed for major and trace constituents from 19 thermal areas of YNP including the Amphitheater Springs area, Nymph Lake area, West Nymph Creek Thermal Area, Norris Geyser Basin, Chocolate Pots, Gibbon Geyser Basin (including Geyser Springs Group, Sylvan Spring area, and Monument Geyser Basin), Secret Valley Hot Springs,...

Regional water-table maps of the Mojave River and Morongo ground-water basins have been published in reports by the U.S. Geological Survey (USGS) every two years since 1992. The water-level reports for the years 1992-2004 were published as USGS Water-Resources Investigations Reports or Scientific Investigations Reports and are available online as separate Portable Document Fomat (pdf) formatted reports, which can be accessed on the "References" page on this website; the water-level contours from most of the...

The Basin Characterization Model (BCM), can translate fine-scale maps of climate trends and projections into the hydrologic consequences, to permit evaluation of the impacts to water availability at regional, watershed, and landscape scales, as caused by changes in temperature and precipitation.
