Beyond Bathymetry: Mapping Acoustic Backscattering From The Deep Seafloor With Sea Beam, Christian De Moustier

Center for Coastal and Ocean Mapping

In its standard mode of operation, the multibeam echosounder Sea Beam produces high resolution bathymetric contour charts of the seafloor surveyed. However, additional information about the nature of the seafloor can be extracted from the structure of the echo signals received by the system. Such signals have been recorded digitally over a variety of seafloor environments for which independent observations from bottom photographs or sidescan sonars were available. An attempt is made to relate the statistical properties of the bottom‐backscattered sound field to the independently observed geologicalcharacteristics of the seafloor surveyed. Acoustic boundary mapping over flat areas is achieved by …

A Review Of The Management And Current Status Of Northern Fur Seals Of The Pribilof Islands, Holly Hansell

Marine Affairs Theses and Major Papers

The North pacific fur seals of Alaska's Pribilof Islands have been subjected to commercial harvest for nearly 200 years. The harvest has been regulated under international agreement almost continuously since 1911; first under the 1911 North Pacific Fur Seal Convention, and following that under the 1957 Interim Convention on Conservation of North Pacific Fur Seals. Both Conventions banned pelagic sealing and divided the restricted land harvest among the four member states, the United States, Canada, Japan, and the Soviet Union. Management under the 1911 convention resulted in a steady increase in the severely depleted fur seal herd, restoring the population …

The Development Of The Shrimp Mariculture Industry In Ecuador And Its Impact On The U.S. Market, Richard A. Norton

Marine Affairs Theses and Major Papers

The demand for tropical shrimp is increasing at a much higher rate than other fish and seafood commodities. With this increase in demand, there has been enormous interest to expand global shrimp production. Mariculture, the term used to describe the practice of farming animal and/or plant life from the sea, has created new opportunities and problems for the future of the global shrimp industry. Since shrimp is considered a high-value food commodity, the development has drawn interest from many United States and European investors. One country in particular, Ecuador, which will be the focus of this discussion, has exemplified many …

The Canadian And Soviet Claims To The Arctic Sea Routes: A Comparative Study, Raymond C. Bourgeois

Marine Affairs Theses and Major Papers

The Arctic Polar Region is becoming increasingly important in terms of strategic operations. especially on the part of the superpowers. Surrounding the Arctic Ocean are two passages through which international navigation is possible. The Northwest Passage lies within Canada's coastline. and the Northeast Passage. within the Soviet Union's northern shores. Both countries have advanced claims to the effect that the waters of these passages are under their respective exclusive jurisdiction; thus. they are claiming these as their internal waters. The US disagrees and maintains that the waters of those northern Arctic sea routes are international waters. This paper discusses the …

Satellite Remote Sensing And Fisheries Applications, Holly M. Turton

Marine Affairs Theses and Major Papers

Satellite remote sensing has the capacity to aid the three major components of a fishery: research, management, and the fishing industry. An evaluation of the potential of satellite-derived data to the fishery is based upon six case studies which are presented as evidence of the capabilities of satellite-borne sensors. Peripheral applications pertaining to the marine environment and possible applications for the future are reviewed. Three basic categories of remote sensing programs related to the fishery are defined: one to test the applicability of the technology to the field of fisheries; another to employ the technology to fisheries research; and a …

Investment Opportunities In The Nigerian Fishing Industry, Ayotunde M. Giwa

Marine Affairs Theses and Major Papers

The major problem facing the Nigerian fishing industry is in its inability to satisfy the demand for tasty yet inexpensive animal protein. Nigeria's marine biological resources are limited and the Gulf of Guinea is among the poorest in the whole of West Africa. Nigeria's population is estimated to have reached about 100 million and is growing at 3.09 per cent per annum. Nigeria's fishing industry is multi-sectoral and composed of the riverine, lake, coastal, estuarine, and culture fisheries. Together they constituted about 1.5 per cent of the GDP in 1976. Up to the present moment, the National has relied on …

Ectoparasitism As A Cost Of Coloniality In Cliff Swallows (Hirundo Pyrrhonota), Charles R. Brown, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Colonially nesting Cliff Swallows (Passeriformes: Hirundo pyrrhonota) in southwestern
Nebraska, USA, are commonly parasitized by hematophagous swallow bugs (Hemiptera: Cimicidae:
Oeciacus vicarius) and fleas (Siphonaptera: Ceratophyllidae: Ceratophyllus celsus). We examined to
what degree these ectoparasites represent a cost of coloniality for Cliff Swallows. The number of
swallow bugs per nest increased significantly with Cliff Swallow colony size. Body mass of nestling
swallows at 10 d of age declined significantly as the number of bugs per nestling increased. By fumigating
half of the nests in some colonies, killing the bugs, and leaving half of the nests as nonfumigated …

The Cruel Deception, Robert Sharpe

Experimentation Collection

With new legislation to replace the Cruelty to Animals Act 1876 near at hand, the powerful vested interest groups whose profits and livelihood depend on laboratory animals are stepping up their campaigns to ensure the survival of vivisection. Have the benefits really been so great, and can vivisection achieve major advances in our present state of health?

History shows (McKeown 1979) that the real reasons for the dramatic increase in life expectancy since the middle of the last century are improvements in nutrition, living and working conditions, hygiene and sanitation, with medical measures only having a relatively marginal effect. The …

The Influence Of Viewing Angle On Elk Hiding Cover In Young Timber Stands, United States Department Of Agriculture, Forest Service

Forestry

Young timber stands, even when providing 100 percent visual concealment for elk when viewed on a horizontal plane, may provide 50 percent or less cover when viewed from an opposing slope at an elevated viewing angle. The higher the viewing angle, the greater the relative cover loss. In a simple linear model, viewing angle explained 52 percent of the variation in hiding cover values. Slightly more variation was accounted for when the data were stratified by tree height. On the average, for a 10-degree elevation in viewing angle, hiding cover decreased by 10 percent. The cover loss relationship was most …

'Hobble Creek' - A Superior Selection Of Low-Elevation Mountain Big Sagebrush, United States Department Of Agriculture, Forest Service

Forestry

This is the foundation document for the release of the 'Hobble Creek' selection of big sagebrush. It is a low-elevation mountain big sagebrush (Artemisia tridentata ssp. vaseyana). 'Hobble Creek' is needed to increase the nutrient content of winter diets of mule deer (Odocoileus hemionus hemionus) and domestic sheep (Ovis aries). This sagebrush exceeds the typical winter forage values in amount of energy-producing compounds, crude protein, phosphorus, and carotene. Of the 186 big sagebrush selections tested. 'Hobble Creek' is the most preferred by wintering mule deer and ranks high in preference by wintering domestic sheep. 'Hobble Creek' does not contain substances …

Visitor Attitudes Toward Wilderness Fire Management Policy -- 1971-84, United States Department Of Agriculture, Forest Service

Wildfires

The historical role of naturally occurring fire in shaping the character of many American landscapes has become an accepted ecological principle. Prior to the coming of the Europeans, natural fires had a major influence in producing a variety of vegetational mosaics. Fire suppression policies of the 20th century, however, significantly changed the evolution of many landscapes compared to what would have occurred had natural fires been allowed to continue. Although natural fires can no longer be allowed to burn in many places because of resource values or danger to the public, such fires may be permitted in many wildernesses and …

Grazing And Management Of Saltland Shrubs, C V. Malcolm, J. E. Pol

Journal of the Department of Agriculture, Western Australia, Series 4

areas of bare saltland on farms need not be unproductive etesores. Many Western Australian farmers are now successfully growing salt-tolerant or halophytic shrubs such as bluebush (Maireana brevifolia), saltbushes (Atriplex spp.) and samphires (Halosarcia spp.) on these areas.

Department of agriculture trials and farmers' experience indicate that if saltland is planted with recommended shrubs, it can provide two months' valuable grazing for sheep during autumn and early winter, a time when paddock feed is scarce. Research by the Department has also identified a range of salt-tolerant shrubs suited to the various types of saltland.

Fisheries Report No 73 - The Western Rock Lobster Fishery 1981 - 1982, R. S. Brown, E. H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. Western Australia produced 10,548 tonnes in 1981/82, out of a total Australian catch of rock lobster of 15,764 tonnes. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and Hancock (1981) and which are designed to limit the total fishing 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 …

Native Hay Production Along A Depth-To-Water-Table Gradient In Eastern Sandhills Wet Meadows, Wheeler County, Nebraska, Jean M. Novacek

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Sandhills region of Nebraska, the largest dune field in the Western Hemisphere, occupies 15 north-central counties and extends over 51,800 km (20,000 mi) (Keech and Bentall, 1971; Ahlbrandt and Fryberger, 1980). Far from a desert, the Sandhills region is entirely vegetated by mixed-grass prairie with numerous wet areas and lakes in interdunal valleys. This rich, grass-covered dune sea stretches 427 km (265 mi) across from east to west and 209 km (130 miles) from north to south. The altitudes range from 670 m (2200 ft) above sea level in the eastern part to 1310 m (4300 ft) in the …

The Effects Of Trace Organic Carbon On Aluminum Solubility, Fernand J. Tiblier

Retrospective Theses and Dissertations

Alum jar tests were performed on raw portable waters of varying TOC. Parameters monitored include alum dose, pH and mixing conditions. Finished waters were analyzed for residual aluminum, residual TOC and hardness in order to investigate the effects of TOC on aluminum residual as would be encountered by alum coagulation and lime softening process in practice.

Three-dimensional graphs of residual aluminum, residual TOC and pH were constructed to illustrate the relationship among these measured parameters for the different sources. Statistical analyses were conducted to verify aluminum-organic complexation at reduced alum dosages for varying TOCs; initial TOC, reaction pH and dose …

The Influence Of Lobster Trap Escape Gaps On Capture And Behavior Of The Spiny Lobster, Panulirus Argus (Latreille), Denis William Frazel

HCNSO Student Theses and Dissertations

Interest in the potential usefulness of lobster trap escape gaps in the Florida spiny lobster fishery prompted an independent examination of their influence on capture and behavior of the spiny lobster, Panulirus argus. A trapping study was conducted off Southeastern Florida during 1984/1985 using control traps, and traps with escape gap openings of 51, 54, and 57 mm. The 51 mm escape gap caught significantly more legal lobsters than any other trap, while the 54 and 57 mm escape gap caught significantly fewer sublegal lobsters. Carapace lengths of lobsters increased as escape gap width increased.

The impact of escape …

Continued Ddt Persistence In Mississippi River Delta Streams: A Case Study, Stephen A. Sewell, Luther A. Knight Jr.

Journal of the Arkansas Academy of Science

Fish samples representative of several trophic levels were taken from the Wolf and Loosahatchie Rivers of western Tennessee during the early 1980s. Results indicate that DDT, with metabolites DDD and DDE, remains common in fish tissues in these areas and approaches the levels recommended as maxima for human consumption by the U.S. Food and Drug Administration. Samples of top carnivores and forage fishes, particularly the gizzard shad, Dorosoma cepedlanum, commonly exceeded 500 ppb DDE. The results are discussed in light of sediment disturbing activities.
