Assessment of diffusive isotopic fractionation in polar firn, and application to ice core trace gas records

Creator:: Buizert, Christo, Sowers, Todd, and Blunier, Thomas
Abstract:: During rapid variations of the atmospheric mixing ratio of a trace gas, diffusive transport in the porous firn layer atop ice sheets and glaciers alters the isotopic composition of that gas relative to the overlying atmosphere. Records of past atmospheric trace gas isotopic composition from ice cores and firn need...

Gases in ice cores

Creator:: Bender, Michael, Sowers, Todd, and Brook, Edward J.
Abstract:: Air trapped in glacial ice offers a means of reconstructing variations in the concentrations of atmospheric gases over time scales ranging from anthropogenic (last 200 yr) to glacial/interglacial (hundreds of thousands of years). In this paper, we review the glaciological processes by which air is trapped in the ice and...

The Fracker’s Figleaf : Booms and Busts of Sustainable Communities and Cohesive Water Governance

Creator:: Groh, Fred
Abstract:: The Marcellus Shale Natural Gas play in Pennsylvania, since its inception, continues to be a source of contention for multiple Pennsylvania stakeholders. The issues that relate to natural gas extraction have seemingly impacted every community within the Marcellus Shale region in some form. As in most common pool resource...

Multidecadal variability of atmospheric methane, 1000–1800 C.E.

Creator:: Mitchell, Logan E., Brook, Edward J., Sowers, Todd, McConnell, J. R., and Taylor, Kendrick
Abstract:: We present a new high-precision, high-resolution record of atmospheric methane from the West Antarctic Ice Sheet (WAIS) Divide ice core covering 1000–1800 C.E., a time period known as the late preindustrial Holocene (LPIH). The results are consistent with previous measurements from the Law Dome ice core, the only other high-resolution...

Creator:: Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd
Abstract:: The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Benefits of Geographic Information Systems for State and Regional Ocean Management

Creator:: Sowers, Derek C.
Abstract:: The current and potential benefits of using geographic information systems (GIS) to support state-level and regional-scale ocean management in the United States are evaluated. Specifically, the role of GIS in facilitating improved integration of management strategies for a variety of resource use issues across multiple management jurisdictions is examined, along...

Spatial and temporal variations of bioavailable polycyclic aromatic hydrocarbons in the lower Willamette River

Creator:: Sower, Gregory J.
Abstract:: Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in...
