An Objective Forecast Method Developed For Lake Ontario Induced Snowfall Systems, K. F. Dewey
An Objective Forecast Method Developed For Lake Ontario Induced Snowfall Systems, K. F. Dewey
School of Natural Resources: Faculty Publications
A research effort was initiated in 1976 to develop an objective lake-effect snowfall forecast model for each of the Great Lakes. It is the purpose of this paper to present the development and evaluation of the forecast method which was created for the Lake Ontario induced snowfall systems. All Lake Ontario lake-effect days were identified for a 10-yead period prior to the 1976 snowfall season. Upper air surface observations were combined with overlake data for these lake-effect periods. The dominant predictors were derived through the diagnostic ability of stepwise multiple discriminant analysis. The final product of this research effort was …

The enclosed reports were compiled for the Colorado River Water Quality Office based on salinity data for Lake Mead and Lake Powell. According to the regional director of the office, the reports are not considered "polished" documents for public distribution. However, he considers them to be "interesting, rough appraisals of general trends that may be very important In our understanding the hydro-salinity system in the Colorado River."
Lake Erie Induced Mesosystems- An Operational Forecast Model, Kenneth F. Dewey
Lake Erie Induced Mesosystems- An Operational Forecast Model, Kenneth F. Dewey
School of Natural Resources: Faculty Publications
All Lake Erie lake-effect days for a 10-year period prior to the 1976-77 snowfall season were utilized in the development of an operational lake-effect snowfall forecast model. Upper air and surface observation were combined with overlake data and analyzed, using stepwise multiple-discriminant analysis. A nine-predictor mesoscale forecast model resulted from this statistical test and its performance was evaluated during the 1976-77 and 1977-78 snowfall seasons. The results of this evaluation indicate that it is possible to predict six intensities of the Lake Erie lake-effect snowstorm using this mesoscale model.

Fisheries Report No 33 - The Western Rock Lobster Fishery 1975 - 1976, G. R. Morgan, E H. Barker
Fisheries Research Reports
iTshe fishery for the western rock lobster Panultrus ecygnus one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. …

Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker
Fisheries Research Reports
The existence of prawn stocks in Shark Bay, Western Australia, has been known since 1904 when the sailing ketch "Rip" on charter to the Western Australian Government, trawled large quantities of prawns from the area between Bernier Island and the mainland, Gale (1905). Although the Fisheries research vessel "Lancelin" trawled potentially commercial quantities of prawns from Shark Bay in the early 1950's, it was not until 1962 that a regular fishery was begun.
Today the prawn stocks of Shark Bay support Western Australia's largest and most consistent prawn fishery, having an annual production currently exceeding 2 000 tonnes. The catch …

A Forest Kingdom Unlike Any Other, Kurt F. Ruppel
A Forest Kingdom Unlike Any Other, Kurt F. Ruppel
Undergraduate Honors Capstone Projects
Olympic National Park (ONP), a natural area 15% larger than Rhode Island, located on the Olympic Peninsula in northwestern Washington State, is a land of diverse contrasts and impressive beauty. It is also a land rich in natural resources (e.g. timber, water power, and recreational potential) that are strongly coveted by man. This dichotomy has led to a number of conflicts during the past hundred years over the policies directing the control, management, and use of this area. It is the purpose of this paper to examine the factors that have shaped that policy and to follow the changes that …
Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon
Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon
Publications (WR)
Analysis of historical nutrient data for Lake Mead indicates that the fertility of the reservoir has decreased which may be the cause for a corresponding decline in the largemouth bass population. However, it appears that fertility can be manipulated by altering the operation of the dam. The depletion of nutrients in the euphotic zone by phytoplankton and subsequent accumulation in the hypolimnion during summer and fall provide a natural nutrient gradient from which water of varying fertility can be drawn for discharge. This combined with alterations in the depth or seasonal pattern of discharge can possibly be used to enhance …

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf
Nebraska Game and Parks Commission: Publications
The Niobrara River heads in the table lands of eastern Wyoming and flows 786 kilometers (km) eastward across Nebraska joining the Missouri River near the town of Niobrara, Nebraska. The Niobrara is the largest Missouri River tributary between the last two mainstem impoundments (Lake Francis Case and Lewis and Clark Lake). Fish movement up the Niobrara is prevented by Nebraska Public Power District's (NPPD's) Spencer Hydroelectric Dam, 63.3 km upstream from the river mouth. The lower reach of the river is turbid and carries a considerable load of sand, silt, and organic debris into the Missouri River. The mean annual …

Critical Areas Planning In Minnesota, Clifton J. Aichinger
Journal of the Minnesota Academy of Science
The Critical Areas Planning Program was established by Minnesota legislation in 1973. Its primary work is with local units of government, regional or state agencies located within areas possessing significant natural, scientific, cultural or historical resources to develop consistent plans and regulations for area use and management. Local units of government prepare the plans and regulations according to guidelines approved by the governor for each critical area'. with technical and financial assistance from the Environmental Quality Board (EQB). The enabling act directed the EQB to develop an inventory of potential critical areas in the state. Inventory methods were evaluated. The …
Spatial Context And Temporal Aspects Of The Sensitive Area Concept In Ontario, Barbara Elizabeth Anderson
Spatial Context And Temporal Aspects Of The Sensitive Area Concept In Ontario, Barbara Elizabeth Anderson
Theses and Dissertations (Comprehensive)
The term “sensitive area” is a product of planning initiatives which have developed within the province of Ontario since the early nineteen seventies. As there are a number of closely related terms utilized the sensitive areas concept generally is defined as the creation of a reserve or the removal of land from unfettered commercial development or intense human use. The concept has been associated with a broad range of environmental concerns such as, the protection of wildlife habitat, maintenance of ecological function, retention of scenic areas and preservation of historic sites. Similar initiatives across North America are surveyed and the …

Management Of Antarctic Krill, Paul Setliff
Management Of Antarctic Krill, Paul Setliff
Marine Affairs Theses and Major Papers
This study pertains to the problem of international activity in an area of political and ecological sensitivity, the Southern Ocean. Of specific concern is the question of which group of states should have a voice in management of Antarctic krill. The niche filled by krill within the ecosystem and its potential as a fishery is discussed. Past international practice has been affected for the most part by the Antarctic Treaty of 1959 which has maintained a somewhat exclusive "club" of nations as the overseers of Antarctic activity. However, states not party to the 1959 Treaty are becoming interested in the …
State Government And Ocs Policy: An Analysis Of The Outer Continental Shelf Lands Act And The Amendments Of 1978, Bruce Vild
Marine Affairs Theses and Major Papers
An Energy Research and Development Administration report indicates that the United States is increasing its dependence on oil from the countries that participated in the 1973 oil embargo. Given the volatile situation in the Middle East at this writing, the Carter Administration's peace initiatives notwithstanding, this seems an imprudent policy. And, at a time when "Project Independence" is a recent memory, there is a great deal of irony in increased importation. It seems in the Nation's best interest to reverse that trend. Natural gas is also in demand, of course, especially in the Northeast during the winter. The best solution …
