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...

The influence of coherent waves on the remotely sensed reflectance

Creator:: Zaneveld, J. Ronald V., Boss, Emmanuel, and Hwang, Paul A.
Abstract:: Oceanic waves have been found to contribute enhanced back-scattering in the direction of the illumination source in studies that assumed the ocean surface to be a random sum of waves. Here we investigate enhanced back-scattering by coherent capillary-gravity wave trains that co-exist near the crests of short gravity waves in...

Comparison of Near-Forward Light Scattering on Oceanic Turbulence and Particles

Creator:: Bogucki, Darek J., Domaradzki, J. Andrzej, Stramski, Dariusz, and Zaneveld, J. Ronald
Abstract:: We examine and compare near-forward light scattering that is caused by turbulence and typical particulate assemblages in the ocean. The near-forward scattering by particles was calculated using Mie theory for homogeneous spheres and particle size distributions representative of natural assemblages in the ocean. Direct numerical simulations of a passive scalar...

Spectral backscattering properties of marine phytoplankton cultures

Creator:: Whitmire, Amanda L., Pegau, W. Scott, Karp-Boss, Lee, Boss, Emmanuel, and Cowles, Timothy J.
Abstract:: The backscattering properties of marine phytoplankton, which are assumed to vary widely with differences in size, shape, morphology and internal structure, have been directly measured in the laboratory on a very limited basis. This work presents results from laboratory analysis of the backscattering properties of thirteen phytoplankton species from five...

Observation of sound focusing and defocusing due to propagating nonlinear internal waves

Creator:: Luo, J., Badiey, M., Karjadi, E. A., Katsnelson, B., Tskhoidze, A., Lynch, J. F., and Moum, J. N.
Abstract:: Fluctuations of the low frequency sound field in the presence of an internal solitary wave packet during the Shallow Water ’06 experiment are analyzed. Acoustic, environmental, and on-board ship radar image data were collected simultaneously before, during, and after a strong internal solitary wave packet passed through the acoustic track....

Mid-frequency sound propagation through internal waves at short range with synoptic oceanographic observations

Creator:: Rouseff, Daniel, Tang, Dajun, Williams, Kevin L., Wang, Zhongkang, and Moum, James N.
Abstract:: Preliminary results are presented from an analysis of mid-frequency acoustic transmission data collected at range 550m during the Shallow Water 2006 Experiment. The acoustic data were collected on a vertical array immediately before, during, and after the passage of a nonlinear internal wave on 18 August, 2006. Using oceanographic data...

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,...

Spatial anatomy of species driven survival: Effects of predation and climate-driven environmental variability

Creator:: Cianelli, Lorenzo, Dingsør, Gjert E., Bogstad, Bjarte, Ottersen, Geir, Chan, Kung-sik, Gjøsæter, Harald, Stiansen, Jan Erik, and Stenseth, Nils C.
Abstract:: The majority of survival analyses focus on temporal scales. Consequently, there is a limited understanding of how species survival varies over space and, ultimately, how spatial variability in the environment affects the temporal dynamics of species abundance. Using data from the Barents Sea, we study the spatiotemporal variability of the...

Cooperative prey herding by the pelagic dolphin, Stenella longirostris

Creator:: Benoit-Bird, Kelly J. and Au, Whitlow W. L.
Abstract:: Sonar techniques were used to quantitatively observe foraging predators and their prey simultaneously in three dimensions. Spinner dolphins foraged at night in highly coordinated groups of 16–28 individuals using strict four-dimensional patterns to increase prey density by up to 200 times. Herding exploited the prey’s own avoidance behavior to achieve...

Modeling the detection range of fish by echolocating bottlenose dolphins and harbor porpoises

Creator:: Au, Whitlow W. L., Benoit-Bird, Kelly J., and Kastelein, Ronald A.
Abstract:: The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured from an energy flux density perspective showed considerably less fluctuation with azimuth than would a pure tone pulse. Using detection...
