Unbalanced particle flux budgets in Crater Lake, Oregon: Implications for edge effects and sediment focusing in lakes

Dymond, Jack; Collier, Robert W.; McManus, James; Larson, Gary L. (American Society of Limnology and Oceanography, Inc., 1996)

Flux estimates show that upward mixing of the deep-water nitrate pool accounts for more than 85% of the total new nitrogen input to the euphotic zone of Crater Lake. Because measured primary productivity (360 mg C m-2 d- ...

Undersea with GIS

Wright, Dawn (ESRI Press, 2002)

Humankind has made more progress during the past 20 years in mapping the surface of neighboring planets than during the past 500 years in mapping the final frontier of Earth: the oceans. Indeed, we still know more about ...

Universal similarity and the thickness of the viscous sublayer at the ocean floor

Chriss, T.M.; Caldwell, Douglas R. (American Geophysical Union, 1984-07-20)

Experiments conducted on the Oregon continental shelf in June 1979 indicate that the boundary layer flow at the seafloor was hydrodynamically smooth. Fine-resolution velocity profiles are used to test the assumption th ...
The Unpredictable Nature of Internal Tides on Continental Shelves

Nash, Jonathan D.; Kelly, Samuel M.; Shroyer, Emily L.; Moum, James N.; Duda, Timothy F. (American Meteorological Society, 2012-11)

Packets of nonlinear internal waves (NLIWs) in a small area of the Mid-Atlantic Bight were 10 times more energetic during a local neap tide than during the preceding spring tide. This counterintuitive result cannot be ex ...
The upper ocean internal wave field: Influence of the surface and mixed layer

Levine, Murray D. (American Geophysical Union, 1987-05-15)

A model is developed to calculate the upper ocean internal wave spectrum as modified by the surface boundary and mixed layer. The Garrett-Munk spectrum is assumed to describe the deep ocean wave field. The main effect ...

Zonal and meridional Seasoar sections centered at 1°50’S, 156°06’E were repeated >30 times in three 20-day periods between November 13, 1992, and February 15, 1993. Both sections were 130 km long, and sampling depth was ...
Upper ocean water properties and currents along paired sections in the Northern California Current, September 1999-2003

Fleischbein, Jane; Huyer, Adriana, 1945-; Kosro, P. Michael, 1951-; Smith, Robert L. (Robert Lloyd), 1935-; Wetz, Jennifer Jarrell; Wheeler, Patricia A. (College of Oceanic and Atmospheric Sciences, Oregon State University, 2006-01)

As part of the U. S. GLOBEC NorthEast Pacific Program we made repeated seasonal hydrographic surveys in the northern California Current system between July 1997 and September 2003. These surveys included sampling al ...
Upper ocean water properties and currents along paired sections in the Northern California current, spring 1998-2003
