An HP-75/HP--86 computer data collection system for recording and displaying logging equipment time studies

Creator:: Campbell, Thomas M.
Abstract:: Time studies of logging equipment are important to determine production rates, calculate logging costs and locate operating inefficiencies. However, using present time study techniques, they are also costly and time consuming to complete. This project will develop a new data gathering and storage technique using the HP-75 portable computer to...

Evaluation of thermal energy storage requirements for a geothermal based district heating system

Creator:: Lawrence, Thomas M.
Abstract:: The thermal energy storage requirements for a district heating system utilizing geothermal energy is evaluated with respect to the system design heating load and local climatic conditions. The local climate pattern is represented by a series of events which characterize the nature and sequence of the cold spells that can...

The geology of the Nicolai Mountain-Gnat Creek area, Clatsop County, northwestern Oregon

Creator:: Murphy, Thomas M.
Abstract:: Twelve rock units, from upper Eocene to middle Miocene are exposed in the Nicolai Mountain-Gnat Creek area. They are, from oldest to youngest: Pittsburg Bluff Formation; Oswald West mudstone; Big Creek sandstone, upper Silver Point mudstone, and Pipeline mudstone members of the Astoria Formation; Depoe Bay Basalt; Grande Ronde Basalt;...

The Batchelor spectrum and dissipation in the upper ocean

Creator:: Dillon, Thomas M. and Caldwell, Douglas R.
Abstract:: Observations of vertical temperature microstructure at ocean station P during the mixed layer experiment (Mile) indicate that the shape of the high-frequency temperature gradient spectrum depends on the relative strengths of turbulence and stratification. For low Cox number ((dT/dz)²)/ (dT/dz)²• the linear range of the Batchelor spectrum is not well...

Wind-driven surface transport in stratified closed basins: Direct versus residual circulations

Creator:: Strub, P. Ted and Powell, Thomas M.
Abstract:: A numerical model has been used to investigate the wind-driven circulation in a stratified basin of moderate size, Lake Tahoe, California-Nevada. Two types of circulation are identified: "direct" circulations, in which the current directions remain relatively constant and the mean circulation formed over several days resembles the instantaneous circulation, and...

Temperature microstructure profiles from the sub-tropical front

Creator:: Dillon, Thomas M. and Caldwell, Douglas R.
Abstract:: Preliminary temperature microstructure profiles resulting from the FRONTS experiment in January 1980 are presented. Also included are selected profiles of the kinetic energy dissipation rate estimated by the Batchelor scale technique.

An oceanic microstructure measuring system

Creator:: Caldwell, D. R. (Douglas R.) and Dillon, T. M. (Thomas M.)
Abstract:: Our primary purpose in developing this instrument is to measure vertical temperature fluctuations in the ocean to the smallest scales at which they exist. This goal dictates the basic concept of the instrument, as C. S. Cox saw in the 1960's. Vertical temperature changes are seen as changes with time...

Crop Response to Lime in the Western United States

Creator:: Jackson, T. L. (Thomas Lloyd), 1922- and Reisenauer, H. M.
Abstract:: The western states include a complex combination of geological, topographical, climatic, and vegetative features. The region extends through 1900 km of latitude and contains three major north-south, storm-directing mountain systems. Most of the region is arid (annual precipitation < 50 em); however, sizeable agriculturally important areas west of the Cascade...

The effects of transect direction on observed spatial patterns of chlorophyll in Lake Tahoe

Creator:: Abbott, Mark R., Powell, Thomas M., and Richerson, Peter J.
Abstract:: Horizontal transects of fluorescence measurements have been used extensively to investigate phytoplankton patchiness. Variance spectra have been calculated from these data, thus quantifying spatial heterogeneity as a function of length scale. Analysis of such fieldwork and associated theoretical investigations is based on the assumption that horizontal patchiness is isotropic. Three...

Microstructure casts during AIWEX : a summary

Creator:: Dillon, T. M. (Thomas M.), Brown, Michael D., and Garrow, Holly C.
Abstract:: The Arctic Internal Wave Experiment (AIWEX) was designed to study the internal wave and microstructure fields in the Beaufort Sea in the early spring. A major goal of the experiment was to verify the hypothesis that the internal wave and microstructure fields beneath the ice are far less energetic than...
