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...
