Introduction to special section : Coastal Advances in Shelf Transport

Creator:: Barth, John A. and Wheeler, Patricia A.
Abstract:: The Coastal Ocean Advances in Shelf Transport (COAST) program conducted an interdisciplinary study of coastal upwelling off central Oregon during summer 2001. Two intensive field efforts during May–June and August 2001 were coordinated with ocean circulation, ecosystem, and atmospheric modeling of the region. A primary goal was to contrast the...

Introduction to special section on Recent Advances in the Study of Optical Variability in the Near-Surface and Upper Ocean

Creator:: Dickey, T., Banner, M. L., Bhandari, P., Boyd, Timothy John, 1958-2013, Carvalho, L., Chang, G., Chao, Y., Czerski, H., Darecki, M., Dong, C., Farmer, D., Freeman, S., Gemmrich, J., Gernez, P., Hall-Patch, N., Holt, B., Jiang, S., Jones, C., Kattawar, G., LeBel, D., Lenain, L., Lewis, M., Liu, Y., Logan, L., Manov, D., Melville, W.

K. P., Zaneveld, R., and Zappa, C. J.
Abstract:: Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...

River influences on shelf ecosystems: Introduction and synthesis

Creator:: Hickey, B. M., Kudela, R. M., Nash, Jonathan, Bruland, K. W., Peterson, W. T., MacCready, P., Lessard, E. J., Jay, D. A., Banas, N. S., Baptista, A. M., Dever, Edward P., Kosro, P. Michael, Kilcher, L. K., Homer-Devine, A. R., Zaron, E. D., McCabe, R. M., Peterson, J. O., Orton, P. M., Pan, J., and Lohan, M. C.
Abstract:: River Influences on Shelf Ecosystems (RISE) is the first comprehensive interdisciplinary study of the rates and dynamics governing the mixing of river and coastal waters in an eastern boundary current system, as well as the effects of the resultant plume on phytoplankton standing stocks, growth and grazing rates, and community...

Very long period magnetotellurics at Tucson Observatory: estimation of impedances

Creator:: Egbert, Gary D., Booker, John R., and Schultz, Adam
Abstract:: Eleven years (1932-1942) of electric potential and magnetic measurement at the Tucson observatory represent a unique very long period magnetotelluric (MT) data set. We report here on a careful reanalysis of this data using modern processing techniques. We have developed and used novel methods for separating out the quasi-periodic daily...

Mapping tropical Pacific sea level: Data assimilation via a reduced state space Kalman filter

Creator:: Cane, Mark A., Kaplan, Alexey, Miller, Robert N., Tang, Benyang, Hackert, Eric C., and Busalacchi, Anthony J.
Abstract:: The well-known fact that tropical sea level can be usefully simulated by linear wind driven models recommends it as a realistic test problem for data assimilation schemes. Here we report on an assimilation of monthly data for the period 1975-1992 from 34 tropical Pacific tide gauges into such a model...

Petrology and Geochemistry of the Galápagos Islands : portrait of a pathological mantle plume

Creator:: White, William M., McBirney, Alexander R., and Duncan, Robert A.
Abstract:: We report new major element, trace element, isotope ratio, and geochronological data on the Galapagos Archipelago. Magmas erupted from the large western volcanos are generally moderately fractionated tholeiites of uniform composition; those erupted on other islands are compositionally diverse, ranging from tholeiites to picritic basanitoids. While these volcanoes do not...

Coseismic slip on the southern Cascadia megathrust implied by tsunami deposits in an Oregon lake and earthquake-triggered marine turbidites

Creator:: Witter, Robert C., Zhang, Yinglong, Wang, Kelin, Goldfinger, Chris, Priest, George R., and Allan, Jonathan C.
Abstract:: We test hypothetical tsunami scenarios against a 4,600-year record of sandy deposits in a southern Oregon coastal lake that offer minimum inundation limits for prehistoric Cascadia tsunamis. Tsunami simulations constrain coseismic slip estimates for the southern Cascadia megathrust and contrast with slip deficits implied by earthquake recurrence intervals from turbidite...

Sources and fluxes of atmospheric trace elements to the Gulf of Aqaba, Red Sea

Creator:: Chen, Ying, Paytan, Adina, Chase, Zanna, Measures, Christopher, Beck, Aaron J., Sañudo-Wilhelmy, Sergio A., and Post, Anton F.
Abstract:: We present the first comprehensive investigation of the concentrations, fluxes and sources of aerosol trace elements over the Gulf of Aqaba. We found that the mean atmospheric concentrations of crustally derived elements such as Al, Fe and Mn (1081, 683, and 16.7 ng m¯³) are about 2–3 times higher than...

Observations of internal gravity waves under the Arctic pack ice

Creator:: Levine, Murray D., Paulson, Clayton A., and Morison, James H.
Abstract:: Internal gravity waves measured under the Arctic pack ice were strikingly different from measurements at lower latitudes. The total wave energy, integrated over the internal wave frequency band, was lower by a factor of 0.03-0.07, and the spectral slope at high frequency was nearly -1 in contrast to the -2...

Behavior of large waterdrops in shear flow

Creator:: Caldwell, Douglas R. and Elliott, W.P.
Abstract:: Nondimensionalized equations of motion for waterdrops, not necessarily obeying Stokes's law, are derived and used to calculate the response of various size drops to changes in horizontal wind speed. We find that (1) cloud drops respond almost instantaneously to changes in wind speed, whereas raindrops require considerable time to adjust,...
