Methods for the estimation and modeling of noise present in multi-beam sonar data, including the magnitude, probability distribution, and spatial correlation of the noise, are developed. Holmin, Arne Johannes Korneliussen, Rolf J Tjøstheim, Dag The beaked whales reacted to these three sound playbacks at sound pressureĮstimation and simulation of multi-beam sonar noise. Ford JKB (1989) Acoustic behavior of resident killer whales (Orcinus orca) off Vancouver.acoustic exposure and behavioral reactions of beaked whales to one controlled exposure each of simulated military sonar, killer whale calls, and band.of simulated military sonar, killer whale calls, and band-limited noise. Users can also change certain parameters to test their management policy.īeaked Whales Respond to Simulated and Actual Navy Sonar Users can easily interact with the model by changing certain inputs (climate change, fertilizer inputs, etc.) to observe the change over the entire system. Currently, the quality component depicts nitrogen-nitrate contaminant. There are four groups of stakeholders of interest: hydropower, agriculture, flood control, and environmental protection. The case study is applied for the Snake River Basin with the fictional name Cutthroat River Basin. The Water-Energy Simulation Toolset (WEST) is an interactive simulation model that helps visualize impacts of different stakeholders on water quantity and quality of a watershed.
