Here we report results from an extensive survey of
dissolved organic carbon (DOC) in the Arctic Ocean, which
was achieved by means of a high-resolution, in situ UV fluorometer
deployed on a nuclear submarine. Based on a strong
linear correlation observed between fluorescence (320 nm excitation,
420 nm emission) and...
Oregon's estuarine wetland landscapes have been changed, especially since the nineteenth century, by diking, dredging, fills, and other alterations. These alterations have removed wetlands from the estuaries, and with them, have removed wetland functions. Currently, efforts are being made to restore estuarine wetlands. The first step in
selecting a site...
Report on CICEET grant research in coordination with Laura Brophy, Marine Resource Management Program, OSU-COAS September 2009 - June 2011.
Tidal wetlands are a powerful carbon sink. They can sequester an order of magnitude
more carbon than any other type of wetland system, and emit only negligible amounts
of methane...

Ronald Thom (Pacific Northwest National Laboratory) presents
Oregon land use specialists believe that the present
definitions of farm and forest land in the state planning
goals are too broad. This results in poor quality resource
lands being as strongly protected as those of top quality.
With persistent growth pressure on rural lands, a means to
distinguish among...

The effect of increasing numbers of non-commercial
farms, or hobby farms, on commercial agriculture is examined
through a comparison of Census of Agriculture data for the years
1978 and 1982. During this time, State Land Use Goal #3,
mandating the protection of farmland, was firmly in place and
exclusive farm...
This thesis conveys the key technical features and scientific applications of a particle-particle ballistic simulation tool (SpaceLab) as well as a high level overview of experiments it was designed for and executed on. SpaceLab simulates spherical particle interactions under any combination of self-gravity, sliding friction, rolling friction, Van-Der-Waals (VDW) cohesion...
We present a spatially extensive record of dinitrogen (N₂) fixation rates and distributions
of N₂ fixing microorganisms along with the results of exogenous phosphorus (P) addition experiments
conducted during a series of cruises in the North Pacific Subtropical Gyre (NPSG). We measured the
N₂ and carbon (C) fixation rates of...
