The Performance of Nearshore Dredge Disposal at Ocean Beach, San Francisco, California, 2005-2007
ISBN: 9781495925849 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Ocean Beach, California, contains an erosion hot spot in the shadow of the San Francisco ebb tidal delta that threatens valuable public infrastructure, as well as the safe recreational use of the beach (fig. 1). In an effort to reduce the erosion at this location, a new plan for the management of sediment dredged annually from the main shipping channel at the mouth of San Francisco Bay was implemented in May 2005 by the United States Army Corps of Engineers, San Francisco District (USACE).

Effects of Wastewater Discharges on Endocrine and Reproductive Function of Western Mosquitofish (Gambusia spp.) and Implications for the Threatened Sa
ISBN: 9781495925917 / Angielski / Miękka / 58 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The Santa Ana River in southern California is impacted by effluents from wastewater treatment plants (WWTP), which are sources of organic wastewater compounds (OWCs) and urban runoff. The Santa Ana River is one of only three river basins supporting native populations of the federally listed Santa Ana sucker (Catostomus santaanae) at the time the fish was included on the list 2000. In 2004 and 2005, a U.S. Geological Survey and U.S. Fish and Wildlife Service study was undertaken to determine if the threatened Santa Ana sucker was potentially exposed to OWCs and endocrine disrupting compounds...

Modeling of Selenium for the San Diego Creek Watershed and Newport Bay, California
ISBN: 9781495926044 / Angielski / Miękka / 56 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The San Diego Creek watershed and Newport Bay in southern California are contaminated with selenium (Se) as a result of groundwater associated with urban development overlying a historical wetland, the Swamp of the Frogs. The primary Se source is drainage from surrounding seleniferous marine sedimentary formations. An ecosystem-scale model was employed as a tool to assist development of a site-specific Se objective for the region. The model visualizes outcomes of different exposure scenarios in terms of bioaccumulation in predators using partitioning coefficients, trophic transfer factors,...

Sediment Transport During Three Controlled-Flood Experiments on the Colorado River Downstream from Glen Canyon Dam, with Implications for Eddy- Sandba
ISBN: 9781495930164 / Angielski / Miękka / 120 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Three large-scale field experiments were conducted on the Colorado River downstream from Glen Canyon Dam in 1996, 2004, and 2008 to evaluate whether artificial (that is, controlled) floods released from the dam could be used in conjunction with the sand supplied by downstream tributaries to rebuild and sustainably maintain eddy sandbars in the river in Grand Canyon National Park. Higher suspended-sand concentrations during a controlled flood will lead to greater eddysandbar deposition rates.

Estuarine Sedimentation, Sediment Character, and Foraminiferal Distribution in Central San Francisco Bay, California
ISBN: 9781495930188 / Angielski / Miękka / 66 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Central San Francisco Bay is the deepest subembayment in the San Francisco Bay estuary and hence has the largest water volume of any of the subembayments. It also has the strongest tidal currents and the coarsest sediment within the estuary. Tidal currents are strongest over the west-central part of central bay and, correspondingly, this area is dominated by sand-size sediment (Figure 0-1). Much of the area east of a line from Angel Island to Alcatraz Island is characterized by muddy sand to sandy mud, and the area to the west of this line is sandy. The sand-size sediment over west-central...

Removal of Nonnative Slider Turtles (Teachemys scripta) and Effects on Native Sonora Mud Turtles (Kinosternon sonoriense) at Montezuma Well, Yavapai C
ISBN: 9781495930669 / Angielski / Miękka / 56 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The National Park Service (NPS) estimates that 234 national parks contain nonnative, invasive animal species that are of management concern (National Park Service, 2004). Understanding and controlling invasive species is thus an important priority within the NPS (National Park Service, 1996). The slider turtle (Trachemys scripta) is one such invasive species. Native to the Southeastern United States (Ernst and Lovich, 2009), as well as Mexico, Central America, and portions of South America (Ernst and Barbour, 1989), the slider turtle has become established throughout the continental United...

Groundwater, Surface-Water, and Water- Chemistry Data from the C-Aquifer Monitoring Program, Northeastern Arizona, 2005?2011
ISBN: 9781495934834 / Angielski / Miękka / 44 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The C aquifer is a regionally extensive multiple-aquifer system supplying water for municipal, agricultural, and industrial use. Increases in water use and/or drought conditions have been reported to cause a lowering of the C-aquifer potentiometric and water-table surfaces (Bills and others, 2000). This decline in water level is observed in monitoring wells and is illustrated in the drying up of Obed Meadows, a natural peat deposit, and Hugo Meadows, a natural wetland-both south of Joseph City, Arizona (Donald J. Bills, U.S. Geological Survey, oral commun. 2011). To address these concerns,...

Pore water from coastal beach and marsh sediments from the northern Gulf of Mexico, pre- and post-landfall of the Deepwater Horizon oil release, were collected and evaluated for toxicity with the sea urchin fertilization and embryological development assays. There were 17 pre-landfall samples and 49 post-landfall samples tested using both assays. Toxicity was determined in four pre-landfall sites and in seven post-landfall sites in one or both assays as compared to a known reference sediment pore-water sample collected in Aransas Bay, Texas. Further analysis and testing of five of the...

Avian Community Responses to Juniper Woodland Structure and Thinning Treatments on the Colorado Plateau
ISBN: 9781495958847 / Angielski / Miękka / 40 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Pinyon-juniper (Pinus spp.-Juniperus spp.) woodlands are estimated to cover 24 to 40 million hectares (ha; 59 to 99 million acres) in the Intermountain West and are distributed extensively across the Colorado Plateau (Samuels and Betancourt, 1982). The distribution of these woodlands has expanded and contracted throughout history (Tausch, 1999), and expansion is presently occurring at a high rate (Miller and Wigand, 1994). Possible catalysts to this rapid expansion include historical fire suppression and livestock grazing (Harris and others, 2003; Johnsen, 1962; Miller and Rose, 1999; West,...
