Structure and dynamics of the Columbia River tidal plume front

Creator:: Kilcher, Levi F. and Nash, Jonathan D.
Abstract:: Time‐dependent buoyant plumes form at the outflow of tidally dominated estuaries. When estuary discharge velocity exceeds plume internal wave speed c, a sharp front forms at the plume’s leading edge that expands from the time‐dependent source. Using observations of the Columbia River tidal plume from multiple tidal cycles we characterize...

The role of turbulence stress divergence in decelerating a river plume

Creator:: Kilcher, Levi F., Nash, Jonathan D., and Moum, James N.
Abstract:: Turbulence controls the composition of river plumes through mixing and alters the plume's trajectory by diffusing its momentum. While believed to play a crucial role in decelerating river-source waters, the turbulence stress in a near-field river plume has not previously been observationally quantified. In this study, finely resolved density, velocity,...

Structure and composition of a strongly stratified, tidally pulsed river plume

Creator:: Nash, Jonathan, Kilcher, Levi F., and Moum, James N.
Abstract:: The initial composition of a river plume depends on the cumulative turbulent entrainment within the estuary and how this dilutes the supplied freshwater. Here we examine the relative roles of turbulence and freshwater input using observations from the Columbia River estuary and plume during two periods with contrasting river flow....

Particle resuspension in the Columbia River plume near field

Creator:: Spahn, Emily Y., Homer-Devine, Alexander R., Nash, Jonathan, Jay, David A., and Kilcher, Levi
Abstract:: Measurements of suspended sediment concentration, velocity, salinity, and turbulent microscale shear in the near-field region of the Columbia River plume are used to investigate the mechanisms of sediment resuspension and entrainment into the plume. An east-west transect was occupied during spring and neap tide periods in August 2005 and May...

Microhabitat selection of brood-rearing sites by greater sage-grouse in Carbon County, Wyoming

Creator:: Schreiber, Leslie A.
Abstract:: Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...

Habitat Selection by Greater Sage-Grouse During Winter in Southeastern Oregon

Creator:: Hagen, Christian A., Willis, Mitchell J., Glenn, Elizabeth M., and Anthony, Robert G.
Abstract:: The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...

1992-1995 waterbird and raptor records for Cabell Marsh, William L. Finley National Wildlife Refuge, Benton County, Oregon

Creator:: Merrifield, Kathy
Abstract:: I conducted 14-22 waterbird and raptor censuses each year from 1992-1995 during late April or early May through October. I observed 44 waterbird and 13 raptor species, including hatch year individuals of seven waterbird species. The records for each census are given.

Abstract:: Production of Kþ mesons in charged-current νμ interactions on plastic scintillator (CH) is measured using MINERvA exposed to the low-energy NuMI beam at Fermilab. Timing information is used to isolate a sample of 885 charged-current events containing a stopping Kþ which decays at rest. The differential cross section in Kþ...
