Modeling West Antarctic Ice Sheet Growth And Collapse Through The Past Five Million Years, David Pollard, Robert M. Deconto

ANDRILL Research and Publications

The West Antarctic ice sheet (WAIS), with ice volume equivalent to ~5 m of sea level, has long been considered capable of past and future catastrophic collapse. Today, the ice sheet is fringed by vulnerable floating ice shelves that buttress the fast flow of inland ice streams. Grounding lines are several hundred meters below sea level and the bed deepens upstream, raising the prospect of runaway retreat. Projections of future WAIS behavior have been hampered by limited understanding of past variations and their underlying forcing mechanisms. Its variation since the Last Glacial Maximum is best known, with grounding lines advancing …

Restoration Of Seagrass Habitat In Tampa Bay Using Large Manatee Grass (Syringodium Filiforme) Sod Units And A Discussion Of Planting Site Sediment Elevation Dynamics, Roger Johansson, Walt Avery, K. B. Hennenfent, J. J. Pacowta

Reports

The final project monitoring results show that the manatee grass transplanting effort was completed successfully. First, the donor site monitoring indicated that disturbances caused by harvesting were fully mitigated within the two year study period. Second, about 1300m2 of manatee grass were established in an area previously devoid of this species. Third, at the end of the study period the per unit area above ground biomass of the restored manatee grass in several of the planting plots was similar to, or may have exceeded the biomass of the donor grass at the time of harvest. Finally, several of the restored …

The Functions And Values Of Fringing Salt Marshes In Northern New England, Usa, Pamela A. Morgan, David M. Burdick, Frederick T. Short

Environmental Studies Faculty Publications

Although large salt marshes of the northeastern United States have been studied extensively, very little is known about the smaller, fringing marshes in this area, despite the fact that they are a common habitat type. We compared the functions and values of five fringing salt marshes (FM) to those of five meadow marshes (MM) along the southern Maine/New Hampshire coast. Specifically we compared their primary production, soil organic matter content, plant diversity, sediment trapping ability and wave dampening properties. Also explored were the relationships between these functions and several physical characteristics at each site, including soil salinity, percent surface slope, …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …

• UNLV is continuing to work with the Architectural Resources Group (ARG) under our SAT grant, to complete Master and Preservation Plans that will guide the SNPLMA-funded museum and field station projects now underway.
• The National Historic Register nomination process, initiated under the SAT grant, was approved and WBR was placed on the NPS National Register of Historic …

A Century Of Climate Change For Fairbanks, Alaska, Gerd Wendler, Martha Shulski

School of Natural Resources: Faculty Publications

Climatological observations are available for Fairbanks, Interior Alaska, for up to 100 years. This is a unique data set for Alaska, insofar as it is of relatively high quality and without major breaks. Applying the best linear fit, we conclude that the mean annual temperature rose from -3.6°C to -2.2°C over the century, an increase of 1.4°C (compared to 0.8°C worldwide). This comparison clearly demonstrates the well-known amplification or temperature change for the polar regions. The observed temperature increase is neither uniform over the time period nor uniform throughout the course of a year. The winter, spring, and summer seasons …

In Situ Bioremediation Of Perchlorate In Soil And Groundwater, David Christopher Bertolacci

Theses Digitization Project

Demonstrating Sustainable Farm Management Systems. Final Report For Rcg05-Ord13, Tara Slaven, Francis Bright, Jodie Hawley, Joe Sherrard

Natural resources research reports

The Ord River Irrigation Area (ORIA) has a 'flow through' irrigation system. That is, irrigation water is diverted from Lake Kununurra and any waste water from the irrigation system and farms flows directly back into the river downstream. This means that any sediment, nutrient or chemicals in tailwater from farms flows straight into the river.

The Ord Land and Water Management Plan 2000 specifies goals to improve surface water quality. The goals are to reduce the load of chemical and nutrient contamination and sediment in tailwater by 40 per cent.

The aim of this project was to develop and demonstrate …

An Inventory And Condition Survey Of The Lower Murchison River Area, Western Australia, P Hennig

Technical Bulletins

The inventory and condition survey of the lower Murchison River area, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 2002 and 2003, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. This survey report presents …

Investigation Of Anthropogenic Greenhouse Gas Emissions Generated Through The Production Of Portland Cement And A Comparison Of Mitigation Strategies, Sheri Marie Haggard

Theses Digitization Project

The purpose of this project investigates the projected anthropogenic C⁰² emissions generated through the production of Portland cement at three manufacturing facilities in southern California. Research consisted of projecting annual greenhouse gas emission inventories for three case studies pursuant to Assembly Bill 32, The Global Warming Solution Act of 2006, which requires mandatory reporting of large producers of greenhouse gas emissions in California.

A System For Estimating Bowen Ratio And Evaporation From Waste Lagoons, Arturo I. Quintanar, Rezaul Mahmood, John H. Loughrin, Nanh Lovanh, Monica V. Motley

High Plains Regional Climate Center: Staff Publications

A low‐cost system was deployed above a swine waste lagoon to obtain estimates of Bowen ratios and characterize lagoon temperatures. The system consisted of humidity and temperature sensors and anemometers deployed above the lagoon, water temperature sensors, and a meteorological station located by the lagoon. To evaluate the system, data was analyzed from the 25th through 28th June 2007. Bowen ratios showed diurnal behavior near the lagoon surface characterized by negative values during day and positive ones at night. Latent (evaporation) and sensible heat fluxes were towards the atmosphere and the lagoon, respectively for most of the day. A diurnal …

Biofuels: Cultivating Energy, Not Invasive Species

National Invasive Species Council

To provide alternatives to petroleum-based energy, the United States (U.S.) government has mandated a greater proportion of plant-based biofuels be integrated into its energy portfolio. However, certain plant species being proposed for biofuel production in the U.S. are invasive species or are likely to escape cultivation and become invasive.

U.S. Executive Order (E.O.) 13112¹ defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states:

“Each Federal agency whose actions may affect the status of invasive species shall, to the extent practicable and permitted …
