A comparison of some estimators in forest sampling

Creator:: Ek, Alan R.
Abstract:: The objectives of this study were to ascertain the relative precision and accuracy of certain estimators on several forest populations and to determine if relative performance could be predicted from knowledge of population characteristics. Performance was tested on three populations of trees drawn from stands in northern Ontario. The first...

The Bob Marshall Wilderness Area of Montana ; a study in land use

Creator:: Merriam, Lawrence C.
Abstract:: A wilderness area, as administered by the U. S. Forest Service, is a tract of undeveloped land over 100,000 acres in size with no roads or provision for motorized transportation. Commercial timber cutting, hotels, stores, and similar developments are prohibited. While there are some exceptions for private holdings and administrative...

Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:: Truong, Thi B.
Abstract:: Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....

Thermochemical Storage Conditions of Caldera Forming Magmatic Systems Revealed by Diffusion Chronometry

Creator:: Lubbers, Jordan E.
Abstract:: Large silicic magmatic systems are responsible for producing the largest explosive volcanic eruptions on earth. These phenomena, although infrequent (i.e., 1 per 100,000 years), impact the global climate, deposit ash over continent sized regions, and significantly alter landscapes. Silicic magmatism also plays important roles in the formation and ongoing evolution...

The Deschutes Formation: evidence of extension-enhanced explosivity in the early High Cascades

Creator:: Pitcher, Bradley W.
Abstract:: The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...

Crystal Records of the Origin, Evolution, and Thermal Histories of Magmas

Creator:: Bradshaw, Richard W., 1985-
Abstract:: In volcanic systems, magma is generally stored in the shallow crust prior to eruption. The conditions of this storage directly impact whether the magma eventually erupts, or crystallizes within the crust to form a pluton. In this dissertation I present four studies that investigate the storage conditions of a number...
