Preliminary Report On A Pleistocene Pond, Garden County, Nebraska, Robert F. Diffendal Jr. May 1977

Preliminary Report On A Pleistocene Pond, Garden County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Discontinuous Pleistocene pond deposits occur along the valley sides of Dankworth Canyon southeast of Lewellen, Nebraska. At one locality the beds exposed in a channel-fill up to six feet thick consist of sand-sized carbonate-rich sediments deposited in alter nating light and dark layers resembling varves. Microscopic examination of disaggregated samples reveals that most of the sediment consists of sand and silt often cemented into tubes. Other components include several kinds of freshwater ostracodes, gastropods, charophyte gyrogonites, and bone-like debris probably from fish.

Daily Maximum And Minimum Temperature Forecasts And The Influence Of Snow Cover, Kenneth F. Dewey Jan 1977

Daily Maximum And Minimum Temperature Forecasts And The Influence Of Snow Cover, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Research into the relationship between snow cover and observed maximum and minimum temperatures is reviewed. An example of the importance of snow cover and forecasting max/min temperatures is presented for this past winter (1976-77). It is shown that there was a warm bias in the MOS temperature forecasts for the northern Great Plains following the receipt of a fresh cover of snowfall. it is proposed that snow cover be incorporated as a conditional predictor to be used only during specific synoptic conditions.

Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel Jun 1975

Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel

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

During the summer of 1974, I sampled sites of vegetation representative of successional trends in plant communities along the Missouri River floodplain from Sioux City, Iowa, to Rulo, Nebraska. Five district community types listed from youngest to oldest are as follows: Salix spp. – dominated, Populus deltoides – dominated, Platanus occidentalis-Ulmus rubra – dominated, Tilia americana-Quercus rubra – dominated, and Quercus macrocarpa-Carya ovata – dominated vegetation.

The technique of relating vegetation succession to age of river stabilization structures was found to be useful and offered a quite precise method of developing a timescale …


Microfossils From The Big Springs Limestone (Pennsylvanian) In Nebraska, Robert F. Diffendal Jr. May 1975

Microfossils From The Big Springs Limestone (Pennsylvanian) In Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Sand-sized residues from partial acetic acid digestion of three samples of the Big Springs Limestone Member of the Lecompton Limestone (Pennsylvanian) from two localities in Cass County, Nebraska, have yielded sixteen genera of microfossils from five major groups of organisms and numerous other whole and partial fossils from seven other groups not identified to the genus level. These fossils include: Protozoa (fusulinids*); Porifera (one spicule type); Bryozoa (two undetermined genera); Brachiopoda (fragments); Gastropoda (two undetermined forms); Ostracoda (Bairdia*, Hollinella*, Moorites*, and one undetermined genus); Crinoidea (whole and partial ossicles*); Echinoidea (whole and partial spines and spine bases*); Holothuroidea (Achistrum …

The Prediction Of Lake Huron Lake-Effect Snowfall Systems, Kenneth F. Dewey Jan 1975

The Prediction Of Lake Huron Lake-Effect Snowfall Systems, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Data was collected during the 1971-72 snowfall season for the Lake Huron basin. The bulk aerodynamic approach, as formulated by Priestly, was utilized to estimate the daily average flux of heat and moisture over the lake. It was hypothesized that discriminant analysis could be employed to determine the threshold value (discriminant index) of the energy flux which is necessary for the occurrence of the lake-effect snowfall system. To determine the validity of this threshold value, the discriminant index was applied to a series of historical data. The results of this analysis indicated that the discriminant index could be utilized to …
