Microbial Observatories: Kilauea Volcano Observatory For Carbon Monoxide-Oxidizing Bacteria, Gary M. King Jul 2007

Microbial Observatories: Kilauea Volcano Observatory For Carbon Monoxide-Oxidizing Bacteria, Gary M. King

University of Maine Office of Research Administration: Grant Reports

Volcanic activity regularly creates new landforms from deposits of tephra, ash and lava. These initially sterile, pristine deposits undergo a range of physical, chemical and biological transformations that lead in some cases to diverse, complex ecosystems such as Hawaiian rainforests. Recent activity by the Kilauea volcano has created unique opportunities to understand the timing and controls of complex ecosystem development, and to analyze the roles of microbes as pioneering colonists that contribute to plant development and succession. The newly established Kilauea Volcano Microbial Observatory will compare the diversity and activity of carbon monoxide-oxidizing bacteria colonizing two different deposits currently 45 …


Magmatic To Solid-State Fabric Transition In A Post-Tectonic Tonalite Pluton, Scott E. Johnson Jan 2004

Magmatic To Solid-State Fabric Transition In A Post-Tectonic Tonalite Pluton, Scott E. Johnson

University of Maine Office of Research Administration: Grant Reports

Magma chambers are an essential component in the construction of oceanic and continental lithosphere, and profoundly influence the thermal and mechanical behavior of the crust and mantle. The mechanical properties of a magma chamber change during cooling and crystallization, as accommodation of deformation changes from magmatic flow to solid-state processes. Thus, to understand the thermo-mechanical evolution of magma chambers, it is crucial to understand the relative importance of magmatic and solid-state flow, and the nature of the transition between them. This project is investigating such a transition preserved in the San Jose pluton, Baja California, Mexico. The pluton postdates the …


Collaborative Research: Volcanic Records From The Siple And Taylor Dome Ice Cores, Antarctica, George A. Zielinski Jun 2003

Collaborative Research: Volcanic Records From The Siple And Taylor Dome Ice Cores, Antarctica, George A. Zielinski

University of Maine Office of Research Administration: Grant Reports

The primary goals of this project were to, 1) evaluate the volcanic acidity record in the Siple Dome A (SDMA) and B (SDMB) ice cores and the Taylor Dome ice core available through the sulfate time series developed by the glaciochemistry group at the University of Maine, 2) undertake a continuous scan of the SDMA core and scan specific sections in the SDMB core to locate and analyze volcanic glass to determine glass composition, and thus source eruptions for the glass and potentially for volcanic sulfate found in the same layer, and 3) evaluate specific sections containing volcanic glass in …
