]]> <![CDATA["Fog and Wind" - Cloud Forests of Santa Rosa Island]]> http://gallery.usgs.gov/videos/594 Fog and wind are ever present on Santa Rosa Island -- one of the Channel Islands offshore of Los Angeles and southern California. Fog condenses on twigs and leaves of island woodland plants, dripping and soaking into the ground. These �cloud forests� harvest the fog and provide critical water for wildlife and the ecosystem.

But grazing in decades past nearly eliminated the native woodlands and changed the fog ecosystem and island hydrology. Now, USGS scientist Kathryn McEachern is working with Channel Island National Park scientists and other collaborators to restore the cloud forests of Santa Rosa Island. As they return, the forests will again harvest water for the island, returning moisture to soils, springs and streams.

]]> <![CDATA[Elevation]]> http://gallery.usgs.gov/videos/567 The National Elevation Dataset (NED) is the primary elevation data product produced and distributed by the USGS National 3D Elevation Program (3DEP). The NED provides seamless raster elevation data of the conterminous United States, Alaska, Hawaii, and the island territories. The NED is derived from diverse source data sets that are processed to a specification with a consistent resolution, coordinate system, elevation units, and horizontal and vertical datums. The NED is the logical result of the maturation of the long-standing USGS elevation program, which for many years concentrated on production of topographic map quadrangle-based digital elevation models. The NED serves as the elevation layer of The National Map, and provides basic elevation information for earth science studies and mapping applications in the United States.

The NED is a multi-resolution dataset that is updated bimonthly to integrate newly available, improved elevation source data. NED data are available nationally at grid spacings of 1 arc-second (approximately 30 meters) for the conterminous United States, and at 1/3 and 1/9 arc-seconds (approximately 10 and 3 meters, respectively) for parts of the United States. Quality Level 3 and higher lidar point cloud are also available in the public domain for download when they are the source of new NED DEMs. Most of the NED for Alaska is available at 2-arc-second (about 60 meters) grid spacing, where only lower resolution source data exist. Part of Alaska is available at the 1/3-arc-second resolution, and plans are in development for a significant upgrade in elevation data coverage of the State over the next 5 years. Specifications for the NED include the following:

Coordinate system: Geographic (decimal degrees of latitude and longitude),
Horizontal datum: North American Datum of 1983 (NAD 83),
Vertical datum: North American Vertical Datum of 1988 (NAVD 88) over the conterminous United States and varies in other areas, and
Elevation units: Decimal meters.

]]> <![CDATA[US Topo]]> http://gallery.usgs.gov/videos/568 US Topo is the next generation of topographic maps from the U.S. Geological Survey (USGS). Arranged in the familiar 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel (and perform) like the traditional paper topographic maps for which the USGS is so well known. In contrast to paper-based maps, US Topo maps provide modern technical advantages that support faster, wider public distribution and enable basic, on-screen geographic analysis for all users.

US Topo maps are available free on the Web. Each map quadrangle is constructed in GeoPDF� format from key layers of geographic data (orthoimagery, roads, geographic names, topographic contours, and hydrographic features) found in The National Map.

US Topo quadrangles can be printed from personal computers or plotters as complete, full-sized, maps or in customized sections, in a user-desired specific format. Paper copies of the maps can also be purchased from the USGS Store (http://store.usgs.gov). Download links and a users guide are featured on the US Topo Web site.

US Topo users can turn geographic data layers on and off as needed; they can zoom in and out to highlight specific features or see a broader area. File size for each digital 7.5-minute quadrangle, about 15-20 megabytes, is suitable for most users. Associated electronic tools for geographic analysis are available free for download.

]]> <![CDATA[Alaska Roundtable]]> http://gallery.usgs.gov/videos/560 Aviation safety, energy development, resource assessments, flood plain management, and a long list of other Federal and State government activities depend on access to accurate, up-to-date topographic maps and data. Remarkably, modern mapping information does not exist over the majority of land in Alaska, where significant resource, safety and national security interests intersect.

To address this issue, the Department of the Interior (DOI) and the State of Alaska co-hosted the Alaska Mapping Roundtable meeting of senior Federal and State executives to raise awareness of status and plans and to explore alternatives for a joint funding strategy for completing topographic mapping in Alaska. The Roundtable was held in Washington, DC on June 28, 2012 and more than 20 Federal departments and bureaus participated because of their mission critical needs for this information. Alaska participants included representatives from the Governor's Office, Department of Transportation, Department of Natural Resources, the University, and the Congressional delegation.

This features an address to the Alaska Roundtable participants by David Hayes, Deputy Secretary of the Department of the Interior. Mr. Hayes outlines the urgency and needs for completing topographic mapping in the State of Alaska.

During this lecture, Dr. Jake Weltzin gives an overview of the USGS sponsored USA National Phenology Network, a national effort to help track the timing of plant and animal activity as an indicator of environmental variation and climate change. This unique project engages both professional and �citizen� scientists to document life cycles of nature. This presentation describes results of some of the research to date and explains how anyone can participate as a �citizen scientist,� tracking plants and animals in their own backyard!

In this episode of Climate Connections, USGS scientists answer questions gathered from the beautiful Glacier National Park in Montana. Questions include:

When I come back in ten years, what will I see in Glacier National Park?
How is climate change impacting the glaciers?
Does all the snow we received this winter help the glaciers?
How do receding glaciers and climate change affect the local economy in terms of recreation, agriculture, tourism?

The disease is estimated to have killed over five million hibernating bats. An outbreak of infectious disease among bats on the order of white-nose syndrome is without precedent, and although insect-feeding wild bats may lack the easily defined monetary value of domestic animals, a recent analysis showed that they provide natural pest control services to American farmers valued at approximately $23 billion per year. Dr. David Blehert discusses this emergent wildlife disease and the profound impacts white-nose syndrome may have in the 21st century.

Even in normal water years, water shortages and use conflicts have become commonplace in many areas of the United States � especially competition among crop irrigation, growing cities and communities, and energy production. Over the next 10 years, the USGS plans to conduct a new assessment of water availability and use. This national Water Census will address critical aspects of recent Federal legislation, including the need to establish a national water assessment program.
