Some physiological studies on cells of Vibrio marinus grown at 4 C and 15 C

Creator:: Haight, Janet Jones
Abstract:: Cells of an obligately psychrophilic marine bacterium, Vibrio marinus, strain MP-1, were grown at 4 C and 15 C and studied for possible physiological differences. No differences were noted in sugar fermentation or temperature-shift growth studies; in both cases adequate nutrients were available. Some differences were noted in viability retention...

Modern and past climate variability in the eastern Pacific warm pool

Creator:: Benway, Heather M.
Abstract:: Westward transport of water vapor across the Panama Isthmus helps to maintain the salinity contrast between the Atlantic and Pacific Oceans, important in thermohaline circulation and global climate. Relatively low sea-surface salinities and a strong, shallow pycnocline in the eastern Pacific warm pool (EPWP) region near Central America reflect high...

Glacial to holocene watermass and continental weathering reconstructions from the Southeast Pacific

Creator:: Muratli, Jesse M.
Abstract:: Sediments of the central Chile margin record changes in ocean circulation and continental erosion associated with large–scale climate change. Here Antarctic– influenced Southern Ocean currents flow equatorward, forming a link between the high– and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important conduit that ventilates South...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

Determination of unsaturation-, growth phase-, and growth rate-dependent hydrogen isotopic fractionation in C₃₇ alkenones produced by Emiliania huxleyi

Creator:: Wolhowe, Matthew D.
Abstract:: Recent works have investigated use of the hydrogen isotopic composition of C₃₇ alkenones (δD[subscript K37s]), lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. I discuss herein the factors impeding such an application and identify the potential alternative use of δD[subscript K37s] measurements as a proxy for non-thermal,...

Physical hydrography and nutrient nitrogen budget of Auke Bay, Alaska

Creator:: Kirk, Deborah Kathleen
Abstract:: Physical sources of nutrient nitrogen for the Auke Bay, Alaska estuarine ecosystem were investigated. These sources included vertical dispersion, advection, and fresh water sources. Hydrographic circulation patterns for the bay, and a nutrient budget for the surface mixed layer were developed. Measurements of temperature, salinity, currents, wind velocity, rainfall and...

Holocene sediments of the South Atlantic Ocean : the calcite compensation depth and concentrations of calcite, opal and quartz

Creator:: Ellis, David Burl
Abstract:: The concentrations of calcite, opal and quartz have been measured in 113 South Atlantic core tops. The remainder of the total sample has been calculated as clay. A method for the quantitative determination of opal has been developed. Calcite is the dominant factor in South Atlantic sediments; its pattern can...

Measurement of the apparent dissociation constants of carbonic acid in seawater at atmospheric pressure

Creator:: Mehrbach, Carl
Abstract:: The apparent dissociation constants of carbonic acid were determined as functions of temperature and salinity in seawater at atmospheric pressure. There is fair agreement between my values of K'₁ and those of Buch et al. (1932), Lyman (1956), and Hansson (1971). My values, on the average, are 6.7% lower than...
