Optical scattering and backscattering by organic and inorganic particulates in U.S. coastal waters

Creator:: Snyder, William A., Arnone, Robert A., Davis, Curtiss O., Goode, Wesley, Gould, Richard W., Ladner, Sherwin, Lamela, Gia, Rhea, William J., Stavn, Robert, Sydor, Michael, and Weidemann, Allen
Abstract:: We present the results of a study of optical scattering and backscattering of particulates for three coastal sites that represent a wide range of optical properties that are found in U.S. near-shore waters. The 6000 scattering and backscattering spectra collected for this study can be well approximated by a power-law...

Reconstructing salinity conditions in Nares Strait (Canadian Archipelago) from stable isotope profiles in bivalve shells

Creator:: Zima, Daniela
Abstract:: Nares Strait is one of three main passages of the Canadian Archipelago that channels freshwater from the Arctic Ocean to the North Atlantic. There are very few observations regarding the role of this region on the present day Arctic freshwater budget, and even less regarding the changes in freshwater fluxes...

Changing concentrations of CO, CH₄, C₅H₈, CH₃Br, CH₃I, and dimethyl sulfide during the Southern Ocean Iron Enrichment Experiments

Creator:: Wingenter, Oliver W., Haase, Karl B., Strutton, Peter, Friederich, Gernot, Meinardi, Simone, Blake, Donald R., and Rowland, F. Sherwood
Abstract:: Oceanic iron (Fe) fertilization experiments have advanced the understanding of how Fe regulates biological productivity and air–sea carbon dioxide (CO₂) exchange. However, little is known about the production and consumption of halocarbons and other gases as a result of Fe addition. Besides metabolizing inorganic carbon, marine microorganisms produce and consume...

Low-pressure phase equilibria of anhydrous anorthite-bearing mafic magmas

Creator:: Kohut, Edward J. and Nielsen, Roger L.
Abstract:: One of the most persistent questions regarding the phase equilibria of mid-ocean ridge basalts (MORB) pertains to the petrogenesis of the anorthitic plagioclase phenocrysts (>An₉₀) that are characteristic of the more primitive members of such suites. Anorthitic phenocrysts are present in many if not most MORB suites in spite of...

Re‐establishment of the native oyster, Ostrea conchaphila, in Netarts Bay, Oregon, USA

Creator:: Archer, Pamela Emily
Abstract:: Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...

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...

Development of 2D models to estimate nearshore bathymetry and sediment transport

Creator:: Splinter, Kristen D.
Abstract:: We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The ﬁrst two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

The inherent optical properties of the oceans: from closure to prediction

Creator:: Barnard, Andrew Heath
Abstract:: Precise in situ measurement of the spectral absorption and scattering coefficients in several regions has revealed patterns in the distribution of the inherent optical properties on spatial scales that were previously unobtainable. The precision of the measurements was found to be consistent and unbiased across a variety of oceanic regimes...

Observing biogeochemical cycles at global scales with profiling floats and gliders: Prospects for a global array

Creator:: Johnson, Kenneth S., Berelson, William M., Boss, Emmanuel S., Chase, Zanna, Claustre, Herve, Emerson, Steven R., Gruber, Nicolas, Kortzinger, Arne, Perry, Mary Jane, and Riser, Stephen C.
Abstract:: Chemical and biological sensor technologies have advanced rapidly in the past five years. Sensors that require low power and operate for multiple years are now available for oxygen, nitrate, and a variety of bio-optional properties that serve as proxies for important components of the carbon cycle (e.g., particulate organic carbon)....

Orthobaric Density: A Thermodynamic Variable for Ocean Circulation Studies

Creator:: de Szoeke, Roland A., Springer, Scott R., and Oxilia, David M.
Abstract:: A new density variable, empirically corrected for pressure, is constructed. This is done by first fitting compressibility (or sound speed) computed from global ocean datasets to an empirical function of pressure and in situ density (or specific volume). Then, by replacing true compressibility by this best-fit virtual compressibility in the...
