Significant changes in nitrogen loads to Jamaica Bay have likely occurred with progressive improvements to Water Pollution Control Plants (WCWPs) that discharge into the Bay. Data available from the New York City Department of Environmental Protection and others will be used to determine loads from WPCPs, combined sewer overflows, and the atmosphere. Selected wells within the USGS water quality database, including those near the landfills that are immediately adjacent to Jamaica Bay, will be used to determine concentrations of nutrients in shallow ground water that enter the bay from ground water seepage. To facilitate evaluation of ground water loads, an existing USGS Finite element model that simulates sub...

The U.S. Geological Survey (USGS) collected hydroacoustic data of the St. Croix River adjacent to the Osceola (WI) boat ramp for hydrographic and benthic mapping prior to the reconstruction project implemented by the National Park Service (NPS). Backscatter is the acoustic reflectivity, which is the measure of energy obtained from the echo intensity, and can provide an indication about the nature of the river bottom and its physical character. Image analysis and classification of backscatter, with the combined datasets of bathymetry (and its derivatives) and ground truthing, can predict surficial substrate, or sediment type. For habitat analysis, these datasets were desired by the NPS to help inform and mitigate...

An August 2004, north-looking photograph, taken by Ron Karpilo, National Park Service, showing a retreating unnamed valley glacier that forms the East Fork of the Teklanika River, Denali National Park and Preserve, Alaska. The photograph shows the retreating, debris-covered terminus of East Fork Teklanika Glacier with an elevated lateral moraine on its west (left) side. Compare with a 1906 photograph from the same location by S.R. Capps. Note: Link to S.R. Capps photograph number 917 is under Web Links below.

The Appalachian Trail (AT), a 14-state footpath from Maine to Georgia, is a unit of the National Park Service that is cooperatively managed and maintained by the National Park Service (NPS), the Appalachian Trail Conservancy, AT Club volunteers, the USDA Forest Service, and other public land-management agencies. Upper elevation and ridge-top ecosystems, which comprise much of the trail corridor, have been impacted by and remain extremely sensitive to acidic deposition. Ridgetop soils that are often low in calcium make the ecosystems of the AT more sensitive to acidic deposition than other ecosystems. Furthermore, upper elevations tend to receive the highest levels of deposition. In areas along the AT, such...

On January 5, 2013, the massive landslide took out a football field-sized portion of Newfound Gap Road (US 441) on the North Carolina side. Approximately 90,000 cubic yards of dirt, rock and roadway crashed 45-50 feet down the side of the mountain. Officials from the Great Smoky Mountains National Park found a subsurface spring underneath the landslide. NPS staff said the spring, along with last week's massive amounts of rainfall, contributed to the landslide Wednesday morning, near mile marker 22 between Collins Creek and Webb Overlook.

Album caption and index card: The mouth of the Little Colorado River as seen from Cape Solitude, 1,167 meters above the river level. This upstream view of the Colorado River was taken after the completion of Glen Canyon Dam and during a period of low flow when Lake Powell was filling. From this vantage point, the interrupted line of dense vegetation marking the flood level is visible, especially on the left bank. A few shrubs (circle) have become established below the upper fringe of plants. The Little Colorado River enters from the right, and its waters appear turbid in this July view. A dense stand of riparian vegetation lines its left bank. (Altitude is 826 meters). Grand Canyon National Park. Coconino County,...

The U.S. Geological Survey (USGS) collected hydroacoustic data of the St. Croix River adjacent to the Osceola (WI) boat ramp for hydrographic and benthic mapping prior to the reconstruction project implemented by the National Park Service (NPS). High-resolution bathymetry data was surveyed using a multibeam sonar. The depth and characteristics of the riverbed are important parameters of habitat for benthic (bottom-dwelling) organisms, and are a fundamental parameter for riverine ecosystems. A terrestrial lidar unit was used to collect shoreline elevation points. These datasets were highly desired by the NPS to help inform and mitigate potential impacts to mussels or benthic habitat.

Water-quality samples were collected from the Upper Delaware Scenic and Recreational River (UPDE) and its tributaries during the period October 1, 2005, to September 30, 2007, to document existing water quality, determine relations between land use and water quality, and identify areas of water-quality concern. A tiered water-quality monitoring framework was used, with the tiers consisting of intensively sampled sites, gradient sites representing the range of land uses present in the basin, and regional stream-survey sites. Median nitrate and total phosphorous concentrations were 1.15 and 0.01 milligrams per liter (mg/L) for three sites on the mainstem Delaware River, 1.27 and 0.009 mg/L for the East Branch Delaware...
Hawaii Volcanoes National Park. 1959 eruption of Kilauea Volcano, first phase of activity in Kilauea Iki Crater. Braided lava cascades down the crater wall to the lava river, the main cascade, and the lava lake, viewed from Byron Ledge overlook. Fume rises from the fountain and from the dead vents. On the north wall of the crater, a number of forest fires sweep up the slope. Photo by U.S. National Park Service, November 15, 1959. Published as Figure 7, U.S. Geological Survey Professional Paper 537-E. Compare with photo rdh00079 taken after activity ceased.

Mount Rainier National Park, Washington. Banks of Kautz Creek about half a mile upstream from the Wonderland Trail shortly after the flood of August 23, 1961. The high discharge steepened and locally undercut streambanks. The sparsely vegetated areas on the terraces on both sides of the creek were covered by the lahars and flood of October 1947. Pierce County, Washington. Photo by U.S. National Park Service, 1961. Published in U.S. Geological Survey Professional paper 677, figure 24. 1971.

The headwaters of the Columbia River Basin in the Northern Rocky Mountains region is widely recognized as a stronghold for native fish, containing some of the last remaining connected cold-water habitats for species such as the threatened bull trout and native westslope cutthroat trout. However, as temperatures rise, non-native invasive fish species could be poised to prosper in the region as conditions start to favor warm-water species over those that require cooler waters to thrive. The spread of invasive fish species has the potential to devastate native fish populations, stream habitats, and the local cultures and economies that depend on healthy aquatic ecosystems – including the region’s multi-billion dollar...
