Gray Whales (Eschrichtius Robustus) Off Sakhalin Island, Russia: Seasonal And Annual Patterns Of Occurrence, David Weller, Bernd Wursig, Amanda Bradford, Alexander Burdin, Sergey Blokhin, Hiroya Minakuchi, Robert L. Brownell Jr. Oct 1999

Gray Whales (Eschrichtius Robustus) Off Sakhalin Island, Russia: Seasonal And Annual Patterns Of Occurrence, David Weller, Bernd Wursig, Amanda Bradford, Alexander Burdin, Sergey Blokhin, Hiroya Minakuchi, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The annual return, seasonal occurrence, and site fidelity of Korean-Okhotsk or western gray whales on their feeding grounds off northeastern Sakhalin Island, Russia, were assessed by boat-based photo-identification studies in 1994-1998. A total of 262 pods were observed, ranging in size from 1 to 9 whales with an overall mean of 2.0'. Sixty-nine whales were individually identified, and a majority of all whales (71.0%) were observed in multiple years. Annual sighting frequencies ranged from 1 to 18 d, with a mean of 5.4 d. The percentage of whales re-identified from previous years showed a continuous annual increase, reaching 87.0% by …

Enhanced Biotransformation Of Carbon Tetrachloride By Acetobacterium Woodii Upon Addition Of Hydroxocobalamin And Fructose, Syed A. Hashsham, David L. Freedman Oct 1999

Enhanced Biotransformation Of Carbon Tetrachloride By Acetobacterium Woodii Upon Addition Of Hydroxocobalamin And Fructose, Syed A. Hashsham, David L. Freedman

Publications

The objective of this study was to evaluate the effect of hydroxocobalamin (OH-Cbl) on transformation of high concentrations of carbon tetrachloride (CT) by Acetobacterium woodii (ATCC 29683). Complete transfor-mation of 470 􀀀M (72 mg/liter [aqueous]) CT was achieved by A. woodii within 2.5 days, when 10 􀀀M OH-Cbl was added along with 25.2 mM fructose. This was approximately 30 times faster than A. woodii cultures (live or autoclaved) and medium that did not receive OH-Cbl and 5 times faster than those controls that did receive OH-Cbl, but either live A. woodii or fructose was missing. CT transformation in treatments with …

Earth In Four Dimensions: Development Of The Ideas Of Geologic Time And History, Robert F. Diffendal Jr. Oct 1999

Earth In Four Dimensions: Development Of The Ideas Of Geologic Time And History, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Changes in ideas and in technology can come about as slow incremental modifications, as well as by major paradigm shifts. In the case of the development of the ideas of geologic history and time, I will try to present these changes broadly and then look at how some of these have affected interpretation of Nebraska geology. Changes of view on three fronts were important in the development of geologic history and time concepts. First is the question of the nature of time. Is time cyclic or is it linear? The Greco-Oriental cultures had a world view based on cosmic cycles, …


Shoreline Management In Chesapeake Bay, C. Scott Hardaway Jr., Robert J. Byrne Oct 1999

Shoreline Management In Chesapeake Bay, C. Scott Hardaway Jr., Robert J. Byrne

Reports

This document describes and illustrates specific, practical responses to shoreline management issues. We will begin with a look at the evolution of the Chesapeake Bay and its ongoing, long-term processes. We will proceed to a discussion of the daily, physical mechanisms that affect shoreline change and the topics professionals address in evaluating sites. We will then discuss strategies for managing shorelines, such as bulkheads, seawalls, revetments, groins, breakwaters, beach nourishment, and marsh fringes, as well as taking no action. Finally, we will give you a framework to apply these ideas in terms of the physical environment at the site and …

Observations Of Shallow Groundwater Contamination Due To Leakage Of Dairy Effluent Ponds On The Swan Coastal Plain, Wa, Richard J. George Dr, D L. Bennett, J R M Bell, Roger Wrigley Oct 1999

Observations Of Shallow Groundwater Contamination Due To Leakage Of Dairy Effluent Ponds On The Swan Coastal Plain, Wa, Richard J. George Dr, D L. Bennett, J R M Bell, Roger Wrigley

Resource management technical reports

In response to the risk of pollution of surface water from farm runoff, dairy farmers have been encouraged to install effluent storage ponds. Previous research has indicated that leachate from these storages can contribute to groundwater contamination. This project assessed the performance of storages at eight sites on the Swan Coastal Plain (SCP), WA. Groundwater conditions were monitored for over three years to study the influence of soil type, water table depth and waste water characteristics.

Regional Hydrology Of The Dixie Valley Geothermal Field, Nevada: Preliminary Interpretations Of Chemical And Isotopic Data, Gregory Nimz, Cathy Janik, Fraser Goff, Charles Dunlap, Mark Huebner, Dale Counce, Stuart Johnson Sep 1999

Regional Hydrology Of The Dixie Valley Geothermal Field, Nevada: Preliminary Interpretations Of Chemical And Isotopic Data, Gregory Nimz, Cathy Janik, Fraser Goff, Charles Dunlap, Mark Huebner, Dale Counce, Stuart Johnson

Charles Dunlap

Chemical and isotopic analyses of Dixie Valley regional waters indicate several distinct groups ranging in recharge age from Pleistocene (<20 ka) to recent (<50a). Valley groundwater is older than water from perennial springs and artesian wells in adjacent ranges, with Clan Alpine range (east) much younger (most <50a) than Stillwater range (west; most > 1OOOa).Geothermal field fluids (-12-14 ka) appear derived from water similar in composition to non-thermal groundwater observed today in valley artesian wells (also -14 ka). Geothermal fluid interaction with mafic rocks (Humboldt Lopolith) appears to be common, and significant reaction with granodiorite may also occur. Despite widespread occurrence of carbonate rocks, largescale chemical interaction appears minor. Age asymmetry of the ranges, more extensive interaction with deep- seated waters in the west, and distribution of springs and artesian wells suggest the existence …


Valuation Of Tree Aesthetics On Small Urban-Interface Properties, Richard Thompson, Richard Hanna, Jay Noel, Douglas D. Piirto Sep 1999

Valuation Of Tree Aesthetics On Small Urban-Interface Properties, Richard Thompson, Richard Hanna, Jay Noel, Douglas D. Piirto

Natural Resources Management and Environmental Sciences

A model was developed to predict the value contribution of forest condition on small urban-wildland interface properties. Sample data were collected on property transactions in the Lake Tahoe Basin of California between 1990 and 1994. A variant of the stand density index (SDI) and a tree health measure were added to a list of traditional property characteristics (i.e., location, house size, lot size) to express the influence of tree care on property value. These aesthetic characteristics were statistically significant despite the expected dominant influence of the traditional characteristics. Values for the forest density and health characteristics were estimated and reveal …

Illinois River 1998 Nutrient And Suspended Sediment Loads At Arkansas Highway 59 Bridge, Marc A. Nelson, Thomas S. Soerens

Technical Reports

Automatic water samplers and a U.S. Geological Survey (USGS) gauging station were established in 1995 on the main stem of the Illinois River at the Arkansas Highway 59 Bridge. Since that time, continuous stage and discharge measurements and water quality sampling have been used to determine pollutant concentrations and loads in the Arkansas portion of the Illinois River. This report represents the results from the measurement and sampling for January 1, 1998 to December 31, 1998.
