Consumer preferences for seafood information attributes

Creator:: Fonner, Robert C.
Abstract:: Changes in consumer preferences have created a need for developing differentiated and higher valued seafood products. Providing consumers with more information about seafood products at the time of purchase has been suggested as a way of differentiating seafood and promoting healthy fisheries. A discrete choice experiment conducted at high-end grocery...

Rip current instabilities

Creator:: Haller, Merrick C. and Dalrymple, Robert A.
Abstract:: A laboratory experiment involving rip currents generated on a barred beach with periodic rip channels indicates that rip currents contain energetic low-frequency oscillations in the presence of steady wave forcing. An analytic model for the time-averaged flow in a rip current is presented and its linear stability characteristics are investigated...

An optical technique for the measurement of longshore currents

Creator:: Chickadel, C. C., Holman, Robert A., and Freilich, Michael H.
Abstract:: We present an optical method (optical current meter) to measure the longshore component of nearshore surface currents by measuring the alongshore drift of persistent sea foam in the surf zone. The method uses short time series of video data collected from an alongshore array of pixels. These space-time data are...

The Effects of Wind Forcing and Background Mean Currents on the Latitudinal Structure of Equatorial Rossby Waves

Creator:: Perez, Renellys C., Chelton, Dudley B., and Miller, Robert N.
Abstract:: The latitudinal structure of annual equatorial Rossby waves in the tropical Pacific Ocean based on sea surface height (SSH) and thermocline depth observations is equatorially asymmetric, which differs from the structure of the linear waves of classical theory that are often presumed to dominate the variability. The nature of this...

Experimental study of nearshore dynamics on a barred beach with rip channels

Creator:: Haller, Merrick C., Dalrymple, Robert A., and Svendsen, Ib A.
Abstract:: Wave and current measurements are presented from a set of laboratory experiments performed on a fixed barred beach with periodically spaced rip channels using a range of incident wave conditions. The data demonstrate that the presence of gaps in otherwise longshore uniform bars dominates the nearshore circulation system for the...

Age of the Batoka basalts, norther Zimbabwe, and the duration of Karoo Large Igneous Province magmatism

Creator:: Jones, D. L., Duncan, Robert A., Briden, J. C., Randall, D. E., and MacNiocaill, C.
Abstract:: Analysis of the Bakota basalts exposed in the Zambezi Gorge some 40 km east of Victoria Falls characterizes them as high Fe, moderately high Ti, and low K, P, and Zr tholeiites. The ⁴⁰Ar-³⁹Ar age determinations are tightly clustered at 180-179 Ma. All of the lavas that were samples have...

Gender identification and growth of juvenile lesser prairie-chickens

Creator:: Pitman, James C., Hagen, Christian A., Robel, Robert J., Loughlin, Thomas M., and Applegate, Roger D.
Abstract:: The ability to ascertain gender and age of juvenile grouse is essential for determining gender-specific population age structure and studying timing of reproductive events, respectively. We examined outer rectrix feathers from juvenile Lesser Prairie-Chickens (Tympanuchus pallidicinctus) captured at 30–40 and 50–60 days post-hatching. Blood samples were collected from most chicks...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Lesser prairie-chicken brood habitat in sand sagebrush: invertebrate biomass and vegetation

Creator:: Hagen, Christian A., Salter, G. Curran, Pitman, James C., Robel, Robert J., and Applegate, Roger D.
Abstract:: Invertebrates are an important food source for grouse chicks, especially within the first 2 weeks of life. Invertebrate abundance is highly patchy and dependent upon herbaceous cover and vegetation structure. We examined the relationship between invertebrate biomass (from sweepnet samples) and habitat structure at lesser prairie-chicken (Tympanuchus pallidicinctus) brood-use and...
