Salt Creek is the largest drainage in the Needles district of Canyonlands National Park. The creek supports one of the most important riparian ecosystems in the park. It is also the heart of the Salt Creek National Register Archeological District, the area with the highest recorded density of archeological sites in the park. A tributary canyon contains the spectacular Angel Arch, a well-known geologic formation that for many years has been a destination point for park visitors. In 1998 the U.S. District Court for the State of Utah ruled, in a lawsuit filed by the Southern Utah Wilderness Alliance, that …


Asian Carp: Key To Identification Jan 2002

Asian Carp: Key To Identification

National Invasive Species Council

Asian carp are large 39-40 in. (40-50 lb.) fish introduced into the U.S. by fish farmers in Southern states in the 1960’s and 70’s to control vegetation and algae blooms. Three of these species, the grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), and silver carp (Hypophthalmichthys molitrix) have been released or have escaped to the wild and are reproducing in many rivers and streams of the Mississippi River Basin. As they continue to expand their range, and show up in commercial and sport fish catches, a need has arisen to develop a simple …


Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson Jan 2002

Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson

Reports

Historical (pre-1930s) seagrass meadows in Tampa Bay are believed to have covered 31,000 ha of the shallow bay bottom. Later, impacts to the bay from increasing population and industrial development of the Tampa Bay area have resulted in large seagrass losses. By 1982, approximately 8,800 ha of seagrass remained. Since 1982, Tampa Bay seagrass monitoring programs have recorded a reversal in the trend of seagrass loss, with the baywide seagrass cover increasing from 9,420 ha in 1988 to 10,890 ha in 1997. However, between 1997 and 1999 the trend again reversed with substantial losses recorded, specifically in the Old Tampa …

Historical And Current Observations On Macroalgae In The Hillsborough Bay Estuary, J.O.R. Johansson Jan 2002

Historical And Current Observations On Macroalgae In The Hillsborough Bay Estuary, J.O.R. Johansson

Reports

To improve the understanding of macroalgae dynamics it was recommended that long-term monitoring of the macroalgae in the bay be initiated. Subsequently, the City of Tampa initiated a Hillsborough Bay macroalgae monitoring program that since 1986 has been providing consistent monthly biomass and species composition information from five fixed transects. In addition to the transect monitoring, low level aerial observations are conducted on a near monthly schedule for estimations of bay-wide macroalgae and seagrass coverage. Results indicate that the annual bay-wide macroalgae coverage has decreased near steadily from about 300ha in the late 1980's to less than 30ha since 1997.

Future Antarctic Margin Drilling: Developing A Science Program Plan For Mcmurdo Sound -- Report Of A Workshop Oxford, Uk April 5–7, 2001, David M. Harwood, Laura Lacy, Richard Levy

ANDRILL Research and Publications

ANDRILL (ANtarctic DRILLing) is a multinational initiative with the objectives to recover stratigraphic core records for use in interpreting Antarctica’s climatic, glacial and tectonic history over the past 50 million years and at varying scales of age resolution (0.1 to 100 thousand years [k.y.]). A key motivation of ANDRILL is that the role of the Antarctic cryosphere (ice sheets, ice shelves and sea-ice) in the global climate system is complex and poorly known. Understanding the past history of ice volume variation in Antarctica and associated physical changes in this region is critical to proper assessment of the global climate system …


Land Use Change And Modification Of Near-Surface Thermal Records In The Northern Great Plains, Rezaul Mahmood, Ken Hubbard, Christy Carlson Jan 2002

Land Use Change And Modification Of Near-Surface Thermal Records In The Northern Great Plains, Rezaul Mahmood, Ken Hubbard, Christy Carlson

High Plains Regional Climate Center: Staff Publications

The North American Great Plains have experienced a rapid overturning of natural grasslands to agricultural land use over the last century. Moreover, in some areas more than 80% of the land use has changed from dry land to irrigated agriculture during the second half of the twentieth century. It is speculated that these changes have modified near-surface atmospheric condition and our modeling study seems to support this. To identify changes in land surface- atmospheric modifications we have applied a soil moistureenergy balance model at three locations in Nebraska: Mead, York, and McCook. The model was applied for three land uses …

Asian Carp Jan 2002

Asian Carp

National Invasive Species Council

Four species of large Asian carps (grass, bighead, silver and black) have been imported into the U.S. for use in the aquaculture industry, and biologists are raising more and more concerns about their effect on native fish and shellfish when released or escaped to the wild. In fact, in the fall of 1999, fish kills in isolated ditches adjacent to the Upper Mississippi River on the Mark Twain National Wildlife Refuge in southern Illinois included large numbers (97%) of Asian carps, but only one individual each of four native fish species. After that incident, reports came in of commercial fishermen …

Methods For Caculating The Chesapeake Bay Benthic Index Of Biotic Integrity, Roberto J. Llansó, Daniel M. Dauer Jan 2002

Methods For Caculating The Chesapeake Bay Benthic Index Of Biotic Integrity, Roberto J. Llansó, Daniel M. Dauer

Benthic Applications

The Chesapeake Bay benthic index of biotic integrity (B-IBI) was developed to assess benthic community health and environmental quality in Chesapeake Bay. The B-IBI evaluates the ecological condition of a sample by comparing values of key benthic community attributes (“metrics”) to reference values expected under non-degraded conditions in similar habitat types. It is therefore a measure of deviation from reference conditions.

The B-IBI is used by the Chesapeake Bay Benthic Monitoring Program, which is conducted by the Maryland Department of Natural Resources (MD DNR) and by the Virginia Department of Environmental Quality (VA DEQ). The program contains two primary elements: …

This study assesses the impact of land use changes on annual energy production of the hydro stations of Cameron Highlands Hydroelectric Scheme. Land use affects sediment load and streamflow of Sungai Telom and Sungai Bertam, which influences power generation and energy production of the several hydro stations in Cameron Highlands. Data of rainfall, streamflow, suspended sediment load, land use and energy output for the period 1964 to 1998 were collected, processed and analysed. Regression analysis, double mass curve method and double ratio technique were used in the assessment. The suspended sediment load and annual runoff of Sungai Telom and Sungai …


Assessment Of Pollution Load For Approved Eia Projects In The Industrial Sector (1988-1998) In Malaysia, Kok Sia Teng Jan 2002

Assessment Of Pollution Load For Approved Eia Projects In The Industrial Sector (1988-1998) In Malaysia, Kok Sia Teng

Student Works (2000-2009)

It is generally recognised that developing countries lacked quantitative decision support tools in the formulation and implementation of pollution control measures necessary to abate environmental impacts associated with industrial development. Reliable and comprehensive simulation models are needed as basic tools for the quantification of industrial pollutant emission load, the assessment of their impacts on the environment as well as the evaluation of pollution control options. As a response to this inadequacy, this research project is conducted as an initial endeavor to use the World Bank's industrial pollution projection program Decision Support System for Integrated Pollution Control (DSS/IPC) for the assessment …
