Abstract
During the last few decades, whale watching has expanded into a billion-dollar industry covering more than 87 countries worldwide. Concern has arisen that this nearly exponential growth may have negative consequences for marine mammals. Various studies have documented short-term effects of cetacean tourism. Recent studies that provide evidence for long-term detrimental effects of whale watching has led the International Whaling Commission to acknowledge that there might be direct fitness reductions associated with this industry (International Whaling Commission 2006). It is likely that at least part of the negative effects can be attributed to increased noise levels. This study sought to quantify the noise levels of two small vessels that are representative for whale-watching and research boats in order to estimate the masking impact on acoustic communication range in two delphinid species commonly approached by whale watchers and researchers.
