The model considers bed material hiding, exposure, sorting, stratification, bed-slope effects, avalanching, non-erodible bed surfaces, and transport due to asymmetrical waves, Stokes drift, roller and ...
متن کاملEffects of training on forced submersion responses in harbor seals.
In several pinniped species, the heart rates observed during unrestrained dives are frequently higher than the severe bradycardias recorded during forced submersions. To examine other physiological components of the classic 'dive response' during such moderate bradycardias, a training protocol was developed to habituate harbor seals (Phoca vitulina) to short forced submersions. Significant chan...
متن کاملHarbor/Mooring Harbor Defense Concept
The long-term goal of this work is an integrated defense system that provides protection of Navy assets, while in port, from the threat posed by covert swimmers. The general concept is to hail, deter, and/or incapacitate the threat by directing a controlled level of low-frequency acoustic energy at the target location. At the system level, the concept requires combining elements of target detec...
