  • Water and bottom properties of a coastal environment derived from Hyperion data measured from the EO-1 spacecraft platform 
    Lee, ZhongPing; Casey, Brandon; Arnone, Robert; Weidemann, Alan; Parsons, Rost; Montes, Marcos J.; Gao, Bo-Cai; Goode, Wesley; Davis, Curtiss O.; Dye, Julie (Society of Photo-Optical Instrumentation Engineers, 2007-12-26)
    Hyperion is a hyperspectral sensor on board NASA’s EO-1 satellite with a spatial resolution of approximately 30 m and a swath width of about 7 km. It was originally designed for land applications, but its unique spectr ...

    Washburn, Libe; Kadko, David C.; Jones, Burton H.; Hayward, Thomas; Kosro, P. Michael, 1951-; Stanton, Timothy P.; Ramp, Steve; Cowles, Timothy (American Geophysical Union, 1991-08-15)
    Observations during the Coastal Transition Zone (CTZ) experiment in summer 1988 reveal the presence of deep phytoplankton layers in a coastal upwelling system. The layers occur throughout the CTZ study area, including ...
  • Watercolors in the Coastal Zone: What Can We See?

  • Wave energy saturation on a natural beach of variable slope 
    Sallenger, Asbury H. Jr.; Holman, Robert A. (American Geophysical Union, 1985-11-20)
    Time series of flow were measured across the inner surf zone during a storm. These data were used to quantify the dependence of wave height (transformed from measured flow) and velocity on local slope and depth. Similar ...
  • Wave run-up on a high-energy dissipative beach 
    Ruggiero, Peter; Holman, Robert A.; Beach, R. A. (American Geophysical Union, 2004)
    Because of highly dissipative conditions and strong alongshore gradients in foreshore beach morphology, wave run-up data collected along the central Oregon coast during February 1996 stand in contrast to run-up data cu ...
  • Wave runup during extreme storm conditions 
    Senechal, Nadia; Coco, Giovanni; Bryan, Karin R.; Holman, Rob A. (American Geophysical Union, 2011-07-30)
    Video measurements of wave runup were collected during extreme storm conditions characterized by energetic long swells (peak period of 16.4 s and offshore height up to 6.4 m) impinging on steep foreshore beach slopes (0. ...
  • Wave variance partitioning in the trough of a barred beach 
    Howd, Peter A.; Oltman-Shay, Joan; Holman, Robert A. (American Geophysical Union, 1991)
    The wave-induced velocity field in the nearshore is composed of contributions from incident wind waves (f > 0.05 Hz), surface infragravity waves (f < 0.05 Hz, lkl < (σ²/gβ) and shear waves (f < 0.05 Hz, lkl > σ²/gβ), ...
  • Wave-Driven Inner-Shelf Motions on the Oregon Coast* 
    Kirincich, Anthony R.; Lentz, Steven J.; Barth, John A. (American Meteorological Society, 2009-11)
    Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using ob ...
  • Wavenumber Spectra of Pacific Winds Measured by the Seasat Scatterometer 
    Freilich, M. H.; Chelton, D. B. (American Meteorological Society, 1986-04)
    Vector winds measured by the Seasat-A Satellite Scatterometer (SASS) are analyzed to determine the spatial structure of oceanic surface winds over wavelengths from 200 to 2200 km. The analysis is performed in four latitu ...
  • Wavenumber-frequency structure of infragravity swash motions 
    Holland, K. T.; Holman, Robert A. (American Geophysical Union, 1999-06-15)
    Alongshore-separated time series of natural swash motions were obtained over a range of environmental conditions using a video technique. Although the frequency spectra and normalized wavenumber spectra for these motions ...
  • The Wavenumber–Frequency Content of Resonantly Excited Equatorial Waves 
    Durland, Theodore S.; Farrar, J. Thomas (American Meteorological Society, 2012-11)
    The theoretical resonant excitation of equatorial inertia–gravity waves and mixed Rossby–gravity waves is examined. Contrary to occasionally published expectations, solutions show that winds that are broadband in both zo ...
  • Wavenumber–Frequency Spectra of Inertia–Gravity and Mixed Rossby–Gravity Waves in the Equatorial Pacific Ocean 
    Farrar, J. Thomas; Durland, Theodore S. (American Meteorological Society, 2012-11)
    In the 1970s and 1980s, there was considerable interest in near-equatorial variability at periods of days to weeks associated with oceanic equatorial inertia–gravity waves and mixed Rossby–gravity waves. At that time, th ...
  • Waves on unsteady currents 
    Haller, Merrick C.; Ozkan-Hollar, Tuba (American Institute of Physics, 2007-12-03)
    Models for surface gravity wave propagation in the presence of currents often assume the current field to be quasi-stationary, which implies that the absolute wave frequency is time invariant. However, in the presence ...
  • Weighting Initial Conditions in Variational Assimilation Schemes 
    Bennett, Andrew F.; Miller, Robert N. (American Meteorological Society, 1991-04)
    An analysis of variational data assimilation schemes for linear dynamical forecast models shows that the penalty functional must include an explicit contribution from the initial conditions in order to ensure a unique, l ...
  • Wetland‐estuarine‐shelf interactions in the Plum Island Sound and Merrimack River in the Massachusetts coast 
    Zhao, Liuzhi; Chen, Changsheng; Vallino, Joe; Hopkinson, Charles; Beardsley, Robert C.; Lin, Huichan; Lerczak, Jim (American Geophysical Union, 2010-10-16)
    Wetland‐estuarine‐shelf interaction processes in the Plum Island Sound and Merrimack River system in the Massachusetts coast are examined using the high‐resolution unstructured grid, finite volume, primitive equations, ...
  • What controls the apparent timescale of solute mass transfer in aquifers and soils? A comparison of experimental results 
    Haggerty, Roy; Harvey, Charles F.; von Schwerin, Claudius Freiherr; Meigs, Lucy C. (American Geophysical Union, 2004)
    Estimates of mass transfer timescales from 316 solute transport experiments reported in 35 publications are compared to the pore-water velocities and residence times, as well as the experimental durations. New tracer exp ...
  • What is the skill of ocean tracers in reducing uncertainties about ocean diapycnal mixing and projections of the Atlantic Meridional Overturning Circulation? 
    Goes, Marlos; Urban, Nathan M.; Tonkonojenkov, Roman; Haran, Murali; Schmittner, Andreas; Keller, Klaus (American Geophysical Union, 2010-12-02)
    Current projections of the oceanic response to anthropogenic climate forcings are uncertain. Two key sources of these uncertainties are (1) structural errors in current Earth system models and (2) imperfect knowledge of ...
  • What Maintains the SST Front North of the Eastern Pacific Equatorial Cold Tongue? 
    de Szoeke, Simon P.; Xie, Shang-Ping; Miyama, Toru; Richards, Kelvin J.; Small, R. Justin O. (American Meteorological Society, 2007-06)
    A coupled ocean–atmosphere regional model suggests a mechanism for formation of a sharp sea surface temperature (SST) front north of the equator in the eastern Pacific Ocean in boreal summer and fall. Meridional converge ...
  • What sets lower limits to phytoplankton stocks in high-nitrate, low-chlorophyll regions of the open ocean? 
    Strom, Suzanne L.; Miller, Charles B.; Frost, Bruce W. (Inter Research, 2000-02-28)
    Phytoplankton biomass in high-nitrate, low-chlorophyll (HNLC) ocean regions exhibits a pronounced stability: variation occurs only within a narrow range of values. The magnitude of this variation has profound ecological ...
  • Wind direction and effect of tree lean on coarse woody debris production
