United States Forest Disturbance Trends Observed Using Landsat Time Series

Creator:: Masek, Jeffrey G., Goward, Samuel N., Kennedy, Robert E., Cohen, Warren B., Moisen, Gretchen G., Schleeweis, Karen, and Huang, Chengquan
Abstract:: Disturbance events strongly affect the composition, structure, and function of forest ecosystems; however, existing US land management inventories were not designed to monitor disturbance. To begin addressing this gap, the North American Forest Dynamics (NAFD) project has examined a geographic sample of 50 Landsat satellite image time series to assess...

A nanoscale pn junction in series with tunable Schottky barriers

Creator:: Aspitarte, Lee, McCulley, Daniel R., and Minot, Ethan D.
Abstract:: PN junctions in nanoscale materials are of interest for a range of technologies including photodetectors, solar cells, and light-emitting diodes. However, Schottky barriers at the interface between metal contacts and the nanomaterial are often unavoidable. The effect of metal-semiconductor interfaces on the behavior of nanoscale diodes must be understood, both...

An autonomous, bottom-transecting vehicle for making long time-series measurements of sediment community oxygen consumption to abyssal depths

Creator:: Smith, K. L., Jr., Glatts, R. C., Baldwin, R. J., Beaulieu, S. E., Uhlman, A. H., Horn, R. C., and Reimers, Clare E.
Abstract:: We have developed and successfully collected data with a unique, bottom-transecting vehicle (ROVER) that permits the first long time-series measurements of sediment community oxygen consumption (SCOC). This instrument has the, following capabilities: (1) it operates as an autonomous, free vehicle on the sea floor to 6,000-m depth for periods up...

Seismic sequence stratigraphy and tectonic evolution of Southern Hydrate Ridge

Creator:: Chevallier, Johanna, Tréhu, Anne Martine, Bangs, Nathan Lawrence Bailey, Johnson, Joel E., and Meyer, H. Jack
Abstract:: This paper presents a seismic sequence and structural analysis of a high-resolution three-dimensional seismic reflection survey that was acquired in June 2000 in preparation for Ocean Drilling Program (ODP) Leg 204. The seismic data were correlated with coring and logging results from nine sites drilled in 2002 during Leg 204....

Investigation of limestone ecotypes of white spruce based on a provenance test series

Creator:: Lesser, Mark R., Cherry, Marilyn, and Parker, William H.
Abstract:: Previous laboratory and field studies have presented evidence for the existence of limestone ecotypes in white spruce (Picea glauca (Moench) Voss). Remeasurements of the range-wide 410 series of provenance trials were used for further evaluation of the existence of these ecotypes. In 2001, heights were measured of 23 provenances grown...

Paired windward and leeward biogeochemical time series reveal consistent surface ocean CO₂ trends across the Hawaiian Ridge

Creator:: Dore, John E., Church, Matthew J., Karl, David M., Sadler, Daniel W., and Letelier, Ricardo M.
Abstract:: Sustained time series have provided compelling evidence for progressive acidification of the surface oceans through exchange with the growing atmospheric reservoir of carbon dioxide. However, few long-term programs exist, and extrapolation of results from one site to larger oceanic expanses is hampered by the lack of spatial coverage inherent to...

Flavin-Containing Monooxygenase S-Oxygenation of a Series of Thioureas and Thiones

Creator:: Henderson, Marilyn C., Siddens, Lisbeth K., Krueger, Sharon K., Stevens, J. Fred, Kedzie, Karen, Fang, Ken, Heidelbaugh, Todd, Phong Nguyen, Chow, Ken, Garst, Michael, Gil, Daniel, and Williams, David E.
Abstract:: Mammalian flavin-containing monooxygenase (FMO) is active towards many drugs with a heteroatom having the properties of a soft nucleophile. Thiocarbamides and thiones are S-oxygenated to the sulfenic acid which can either react with glutathione and initiate a redox-cycle or be oxygenated a second time to the unstable sulfinic acid. In...

Microbial activity in the alteration of glass from pillow lavas from hole 896a

Creator:: Furnes, Harald, Thorseth, Ingunn H., Tumyr, Ole, Torsvik, Terje, and Fisk, Martin R.
Abstract:: Within the altered parts of the glass rim of pillow lavas of Hole 896A, at depths at least 432 m below seafloor (237 m below the top of volcanic basement), microbes have been identified. This is indicated by the size and shapes of alteration textures and verified by the presence...

Tillamook volcanic series : further evidence for tectonic rotation of the Oregon Coast Range

Creator:: Magill, James, Cox, Allan, and Duncan, Robert A.
Abstract:: Paleomagnetic directions from the Eocene Tillamook Volcanic Series of the Oregon Coast Range point 460 clockwise from the expected Eocene field direction. Potassium argon dating of six dikes and flows from this formation yields a mean age of 44.3 ± 0.6 m.y. These results establish that the Oregon coastal block...
