The effects of PCB exposure on the behavior of the shore crab Hemigrapsus oregonensis

Creator:: Pearson, Walter H.
Abstract:: The behavior of the shore crab Hemigrapsus oregonensis was assessed with and without exposure to polychlorinated biphenyls (Aroclor 1260). After describing the crab's behavioral repertoire, activity budgets were developed from observations of the time crabs spent in 20 categories of shelter use, posture, and activity while held in habitat replicas...

The sediment response of a dissipative beach to variations in wave climate

Creator:: Haxel, Joseph H.
Abstract:: Using wave and wind data from nearby buoys and gauges, real time kinematic global positioning system (RTK-GPS) and light detection and ranging (lidar) topographic survey data, and a robust video record, we have quantified the Large Scale Coastal Behavior (LSCB) of a dissipative end member beach in the Pacific Northwest....

Motions of a small spar buoy

Creator:: Dorman, Clive Edgar
Abstract:: The motions of a small spar buoy were measured in deep water. The measured variables were two buoy tilts, three accelerations, two wave slopes and the wave height. The variables were corrected for buoy motion and rotated to stationary coordinates, Fast Fourier Transformed, and analyzed spectrally. Analysis included power spectra,...

Tectonics of the East Pacific Rise, 5⁰ to 12⁰S

Creator:: Rea, David K.
Abstract:: The portion of the East Pacific Rise (EPR) between 5° and 12°S can be subdivided into three areas by fracture zones that offset the rise axis at about 6.5°S and 9°S. In all three regions, the spreading axis of the EPR is defined by a topographic block 300 to 350...

Modeled Larval Connectivity Patterns in two Coral Reef Regions : the Western Caribbean and the Kenyan-Tanzanian Shelf

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: Tropical coral reef ecosystems are very important from both the ecological and economical points of view. However, they are also particularly fragile, and have been declining in recent years in most regions of the world, since they are highly susceptible to anthropogenic stressors operating at global scales (e.g., global warming...

Remote measurements of waves and currents over complex bathymetry

Creator:: Chickadel, Carmine C. (Carmine Christopher)
Abstract:: Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...

Investigating Plate Boundaries through New High-Resolution Bathymetry and Seismic Data; 2 Case Studies from the Cascadia Subduction Zone and San Andreas Fault

Creator:: Beeson, Jeffrey Watson
Abstract:: Contiential margins on plate boundaries are complex systems with morphologies and characteristics dictated by the interplay of sediment deposition and erosion, tectonic faulting, folding, and strong ground motion generating mass wasting events. With ever increasing advances in high-resolution remote sensing techniques these systems are increasingly becoming illuminated. A ~120 km...

Photoperiod and the timing of pupping in the Pacific harbor seal (Phoca vitulina richardsi) with notes on reproduction in northern fur seals and Dall porpoises

Creator:: Temte, Jonathan L.
Abstract:: Birth and pupping season records of Pacific harbor seals (Phoca vitulina richardsi) were used in an analysis of photoperiod effect on the timing of birth in this species. Dates and latitudes of births were converted into photoperiods using a photoperiod equation. Sequential dates from parturition were converted into photoperiods and...

Density separation of clay minerals

Creator:: Nelsen, Terry A.
Abstract:: Illite, chlorite, montmorillonite and kaolinite, as well as natural marine sediments and mixtures of the standards were subjected to density separation by centrifugation in a linear heavy-liquid gradient. The density layers yielded by centrifugation were recovered and analyzed by X-ray diffraction. Separates were not monomineralic but rather were polymineralic usually...
