Catastrophic Wave Erosion On The Southeastern Coast Of Australia: Impact Of The Lanai Tsunamis Ca. 105 Ka?, R. W. Young, Edward A. Bryant Jan 1992

Catastrophic Wave Erosion On The Southeastern Coast Of Australia: Impact Of The Lanai Tsunamis Ca. 105 Ka?, R. W. Young, Edward A. Bryant

Faculty of Science - Papers (Archive)

Sand barriers along the coast of southern New South Wales, dating from the last interglacial, have been almost completely destroyed, most probably by a catastrophic tsunami. Evidence for catastrophic wave erosion can also be traced to heights of at least 15 m above present sea level on coastal abrasion ramps. These erosional features lie above the range of effective erosion by contemporary storm waves, and cannot be attributed to either eustatic fluctuations or local uplift. Chronological evidence for the timing of the destruction of the last interglacial barriers suggests that tsunami generated by the submarine slide off Lanai in the …


Evidence Of Tsunami Sedimentation On The Southeastern Coast Of Australia, Edward A. Bryant, R. W. Young, David M. Price Jan 1992

Evidence Of Tsunami Sedimentation On The Southeastern Coast Of Australia, Edward A. Bryant, R. W. Young, David M. Price

Faculty of Science - Papers (Archive)

In the coastal region, the highest magnitude storms cannot always be invoked to account for large-scale, anomalous sediment features. Any coastline in the Pacific Ocean region can be affected by tsunamis, including Australia which historically lacks evidence of such events. Geologically, tsunamis along the New South Wales coast have deposited a suite of Holocene features that consist of anomalous boulder masses, either chaotically tossed onto rock platforms and backshores or jammed into crevices; highly bimodal mixtures of sand and boulders; and dump deposits consisting of well sorted coarse debris. In addition many coastal aboriginal middens were disturbed by such events. …

The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske Jan 1992

The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske

Journal of the Iowa Academy of Science: JIAS

Specific surface area is a property used by earth scientists to estimate the proportion of expandable clay minerals in soils. In this study, specific surface area method is shown to compare favorably with standard clay mineralogical techniques in determining gross differences in expandable clay mineral content in tills. The results of over 100 measurements on till samples from Iowa indicate undifferentiated pre-Illinoian tills from southern and southwestern Iowa have the highest specific surface area values of Iowa tills (ranging from nearly 100 to greater than 150 m2/g) and Wisconsinan Dows Formation tills have the lowest average specific surface …

Executing Multidatabase Transactions, Mansoor Ansari, Marek Rusinkiewicz, Linda Ness, Amit P. Sheth Jan 1992

Executing Multidatabase Transactions, Mansoor Ansari, Marek Rusinkiewicz, Linda Ness, Amit P. Sheth

Kno.e.sis Publications

In a multidatabase environment, the traditional transaction model has been found to be too restrictive. Therefore, several extended transaction models have been proposed in which some of the requirements of transaction, such as isolation or atomicity, are optional. The authors describe one of such extensions, the flexible transaction model and discuss the scheduling of transactions involving multiple autonomous database systems managed by heterogeneous DBMS.

The scheduling algorithm for flexible transactions is implemented using L.0, a logically parallel language which provides a framework for concisely specifying the multidatabase transactions and for scheduling them. The key aspects of a flexible transaction specification, …

The Distribution Of Amphipods In Southeastern Minnesota And Their Relation To Water Quality And Land Use, James A. Muck, Raymond M. Newman Jan 1992

The Distribution Of Amphipods In Southeastern Minnesota And Their Relation To Water Quality And Land Use, James A. Muck, Raymond M. Newman

Journal of the Iowa Academy of Science: JIAS

The distribution of the amphipods Gammarus pseudolimnaeus and Hyalella azteca was determined from 97 designated trout streams in Minnesota, along with temperature, conductivity, and nitrate levels. Streams were classified into 4 land use/geology groups. G. pseudolimnaeus was found in 11 counties and at 123 of 168 sites in 83 of the 97 streams sampled. Hyalella azteca was found in 7 counties at 26 sites m 21 streams. Spearman rank correlations showed a high degree of correlation between nitrate (range: 0-11 mg N/L), conductivity (range: 325-870 μS/cm), and geology. The relative abundance of G. pseudolimnaeus was negatively correlated with nitrate, geology …

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker Jan 1992

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker

Journal of the Iowa Academy of Science: JIAS

Fens are peatlands which are dependent on groundwater discharge to provide nutrient enrichment. Fens are found in a variety of landscape positions and in most Iowa landform regions. This paper presents a classification system for Iowa fens based on landscape position, stratigraphy, and hydrologic factors. Iowa fens can be separated into six categories: 1) fens along valley wall slopes; the groundwater source for these fens is sand and gravel buried between glacial tills (inter-till); 2) fens in hummocky topography on the northwestern margin of the Des Moines Lobe landform region; the water source is sand and gravel buried within glacial …


Necklace Radio Transmitter Attachment For Pheasants, Terry Z. Riley, Bruce A. Fistler Jan 1992

Necklace Radio Transmitter Attachment For Pheasants, Terry Z. Riley, Bruce A. Fistler

Journal of the Iowa Academy of Science: JIAS

We tested a pre-assembled, necklace-radio-transmitter-attachment design on female ring-necked pheasants (Phasianus colchicus) in northern Iowa. Birds were captured by nightlighting and bait trapping between September 1989 and March 1990. Radio transmitters were attached to 128 using a wire necklace. Two birds had problems adapting to the necklace, and 3 birds removed them. Twenty-three birds were still alive and wearing necklaces at the end of the study, for an average of 318 (SD= ± 52) days. Ease of attachment, long durability, light weight, and minimal bulk make the necklace an effective alternative to harness and poncho mounts.

History Of Mammal Study In Iowa, John B. Bowles Jan 1992

History Of Mammal Study In Iowa, John B. Bowles

Journal of the Iowa Academy of Science: JIAS

The first records of mammals in Iowa were from explorers, survey parties heading westward and early seeders. Generation of checklists of state mammals began in 1840 and culminated with the annotated list by Scott (1937) and biogeographic analysis by Bowles (1975). Recent focus has been on rare species status and mammalian ecology, e.g., Loess Hills, riparian habitat, agricultural practices, and reestablished grasslands.


The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper Jan 1992

The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper

Journal of the Iowa Academy of Science: JIAS

The 132-year record of UIMNH essentially mirrors historical and on-going trends in related institutions. As scholarship grew in the natural sciences during the 19th century, natural history museums became centers for scientific research. A "Golden Age" of museum-based expeditionary work and taxonomic research was marked at UI by the careers of curator/naturalists Calvin, Nutting, Macbride, and Shimek. Systematic biology and paleontology thrived with the accumulation of extensive collections. De-emphasis of "natural history" studies followed after 1920-30 with a concomitant growth in cellular and molecular biology. In seeking new directions and financial support, many museums, including UIMNH, shifted emphasis to public …

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl Jan 1992

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl

Journal of the Iowa Academy of Science: JIAS

Little Wall Lake, a shallow 104 ha glacial lake in Hamilton County, Iowa, has been manipulated for about 50 years by fishery managers in an attempt to provide a stable sport fishery. Managers have used dredging, water level manipulation, aquatic vegetation control, mechanical fish removal and fish eradication with toxicants, sport fish stocking, introduction of piscivorous fish, artificial habitat structures, and winter aeration. Attempts to stabilize the fishery have been unsuccessful, and because of overpopulation and stunting of panfishes, total fish eradications were conducted in 1977 and 1989. We review the history of management efforts on the lake, and suggest …


Diatoms Of Northeastern Iowa Fens, Stephen P. Main, David E. Busch Jan 1992

Diatoms Of Northeastern Iowa Fens, Stephen P. Main, David E. Busch

Journal of the Iowa Academy of Science: JIAS

Analysis of water samples from 10 fens in NE Iowa, collected 13-14 November 1987, revealed a gradient from acid, low conductivity water conditions (pH 5.6, alkalinity 30 mg/I HCO, conductivity 65 μmho, total hardness 30 mg/I Ca) to circumneutral, moderately conductive conditions (pH 7 .2, alkalinity 390 mg/I, conductivity 705 μmho, total hardness 380 mg/I Ca). Three sites along this gradient were sampled 15 May 1988 and 3 September 1988 to evaluate seasonal variation in water conditions. Examination of composite diatom samples collected concurrently with the water samples yielded 150 taxa, of which 14 are new Iowa distributional records and …

Book Review: Landforms Of Iowa, Michael L. Thompson Jan 1992

Book Review: Landforms Of Iowa, Michael L. Thompson

Journal of the Iowa Academy of Science: JIAS

Many of us are interested in the landscape around us. We ask: Why is this hill so steep or why is that valley so wide? Why does my garden's soil have so much clay? Why does Iowa have no mountains' Landforms of Iowa should capture a broad audience of teachers, students, agriculturalists of all sorts, historians, homemakers, naturalists, botanists, biologists, foresters, geographers, civil engineers, as well as geologists and pedologists-in short, just about any Iowan who has ever wondered how and when the landscape at his or her doorstep or outside the car window was fashioned. Its stated purposes are …

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany Jan 1992

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany

Journal of the Iowa Academy of Science: JIAS

Bessey was a multidirectioned innovator and evangelist of botanical education, conservation, and scientific agriculture. For example, he initiated the first undergraduate laboratory using microscopes for botany instruciton and he had no peer as a botany teacher in the latter part of the 19th century. His enthusiasm about the natural history of Iowa and surrounding states broadened the horizons of innumerable students and he was one of the founders of the Iowa Academy of Science. An organization man, Bessey quickly became president of any group with which he became affiliated, and eventually was both nationally and internationally known through his text …
