Production and export of biogenic silica in the Southern Ocean

Creator:: Sigmon, Daniel E.
Abstract:: Dissolved silicic acid (Si(OH)4) and biogenic silica (BSiO2) concentrations were measured on four different cruises in the Southern Ocean along 1700 W from late October 1997 to mid-March 1998. These data were used to construct a vertically integrated Si budget in the surface layer from 58° to 68° S. Throughout...

Observations on the evolution of shoaling nonlinear internal waves in Massachusetts Bay using shipboard X-band radar

Creator:: Nelson, Brian G.
Abstract:: During four cruises in July and September of 2008 and 2009, the shipboard X-band radar was tuned to detect the modulated bands of surface roughness caused by converging and diverging currents associated with high-frequency nonlinear internal wave (NLIW) packets. The data collected was used to quantify the propagation direction (ϴp),...

Mixing of chlorophyll from the Middle Atlantic Bight cold pool into the Gulf Stream at Cape Hatteras in July 1993

Creator:: Wood, A. Michelle, Sherry, Nelson D., and Huyer, Adriana, 1945-
Abstract:: In July 1993 we collected hydrographic data and information on chlorophyll distribution on the continental shelf north of Cape Hatteras and across the shelf break at Cape Hatteras. The data show that a warm, transparent mixed layer lies over much colder, euphotic, chlorophyll-rich bottom water on the shelf. This layer...

A terrestrial organic matter depocenter on a high-energy margin adjacent to a low-sediment-yield river : the Umpqua River margin, Oregon

Creator:: Hastings, Roxanne H.
Abstract:: Small, mountainous river systems have been increasingly studied due to their importance as sources of fluvial sediment and organic matter to the coastal ocean. Thus far, studies of small, mountainous river systems have focused on rivers with very high sediment loads. The well-studied Eel River dispersal system in northern California...

Ecology of Greenland halibut (Reinhardtius hippoglossoides) during the early life stages in the Eastern Bering Sea and Aleutian Islands

Creator:: Sohn, Dongwha
Abstract:: Greenland halibut (Reinhardtius hippoglossoides) have decreased in the eastern Bering Sea and Aleutian Islands since the 1970s. The reasons behind the poor recruitment are unknown, and important knowledge gaps of the ecology of the early life stages have been identified. The objectives of thesis research were (1) to examine geographic...

Spatial and temporal variability of absorption by dissolved material at a continental shelf

Creator:: Boss, Emmanuel, Pegau, W. Scott, Zaneveld, J. Ronald, and Barnard, Andrew H.
Abstract:: Optical properties of dissolved (colored dissolved organic material (CDOM)) and particulate matter and hydrographic measurements were obtained at the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. To assess the temporal and spatial variability, time series were...

On the Use of QuikSCAT Scatterometer Measurements of Surface Winds for Marine Weather Prediction

Creator:: Chelton, Dudley B., Freilich, Michael H., Sienkiewicz, Joseph M., and Von Ahn, Joan M.
Abstract:: The value of Quick Scatterometer (QuikSCAT) measurements of 10-m ocean vector winds for marine weather prediction is investigated from two Northern Hemisphere case studies. The first of these focuses on an intense cyclone with hurricane-force winds that occurred over the extratropical western North Pacific on 10 January 2005. The second...

Clear Lake sediments: Anthropogenic changes in physical sedimentology and magnetic response

Creator:: Osleger, David A., Zierenberg, Robert A., Suchanek, Thomas H., Stoner, Joseph, Morgan, Sally, and Adam, David P.
Abstract:: We analyzed the sedimentological characteristics and magnetic properties of cores from the three basins of Clear Lake, California, USA, to assess the depositional response to a series of land use changes that occurred in the watershed over the 20th century. Results indicate that distinct and abrupt shifts in particle size,...

Bacterioplankton in the Oregon upwelling system: distribution, cell-specific leucine incorporation, and diversity

Creator:: Longnecker, Krista
Abstract:: Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...
