"Underwater noise created by vessel traffic in the world's oceans may be detrimental to marine life that relies on acoustic senses for survival. An analytical study was completed which examined changes in vocal behavior of subpod A36, killer whales (Orcinus orca) that reside off Vancouver Island. The average call rate of each call type was calculated from the recordings, and call rates were found to significantly decrease in the presence of vessel noise. Structural characteristics of specific call types such as differences in frequency, duration, and harmonics were also examined and statistically compared with and without boat noise. Differences found include a decreased number of harmonics in the N5 call, and a more peaked distribution of the average frequency of the first harmonic of the N4 call when associated with vessel noise. The significance of the result relative to the possible disturbance of these killer whales is uncertain"--Leaf iii.

Download The Effects of Noise on Aquatic Life Book in PDF, ePub and Kindle
The Second International Conference on the Effects of Noise on Aquatic Life will take place in Ireland August 15-20, 2010. The main emphasis of the conference will be on defining the current state of knowledge. However, we will also assess progress in the three years since the First conference. The Second conference will place strong emphasis on recent research results, the sharing of ideas, discussion of experimental approaches, and analysis of regulatory issues.

The widespread loss of apex consumers in marine, terrestrial, and freshwater ecosystems throughout the world has precipitated profound trophic cascades and switches to different ecological states. However, conserving top predators can deliver broad biodiversity benefits and improve ecosystem resiliency. Effective conservation and management policy is predicated on a species’ distribution and abundance in a given area and time. In this dissertation, I provide new insight into killer whale (Orcinus orca) distribution, vocal behavior, and abundance in the Gulf of Alaska using passive acoustic monitoring and advance long-term monitoring capacity for this species. First, I describe the year-round spatiotemporal distribution and daily acoustic residency patterns of southern Alaska resident (fish-eating) and two populations of transient (mammal-eating) killer whales. I found distinct seasonal patterns across locations for each genetically distinct population and discovered that both resident and transient killer whales used the coastal monitoring areas more extensively than previously known—including in winter. Second, I estimated resident and transient killer whale calling rates, a prerequisite to acoustic abundance estimation. I found that the mean calling rate for southern Alaska resident (fish-eating) killer whales was consistent across space, time, ambient noise level, which pod was calling, and the presence of other pods. Gulf of Alaska transient (mammal-eating) killer whale calling rates were higher than resident’s and differed across locations. AT1 transients (mammal-eating) produced fewer calls more rapidly than Gulf of Alaska transients, and their mean rate was stable across spatiotemporal factors. Although transients call less often than residents, I found that once vocalizing, they do so at a higher rate. Finally, I estimated and modeled the year-round daily acoustic abundance of resident and transient killer whales across distinct areas in the Gulf of Alaska and developed Bayesian time series models to describe seasonal patterns and predict future abundance. Acoustic abundance estimates for the southern Alaska resident and Gulf of Alaska transient killer whales matched expectations from visual studies. I established distinct seasonal abundance patterns across areas, and acoustic monitoring enabled killer whale abundance estimation across a greater spatiotemporal extent than other methods. This work is critical for an accurate understanding of killer whales’ top-down forcing effects in the marine ecosystem, as well as to inform conservation and management policy for this federally protected species.
