Is it possible to go whale watching off the coast of Peru?: A case study of humpback whales ¿Es posible hacer turismo de observación de ballenas en la costa de Perú?: Un caso de estudio con ballenas jorobadas

Latin American Journal of Aquatic Research, 2011
Whale watching is the human activity of encountering cetaceans in their natural habitat for recreational and scientific purposes. Despite the high diversity of cetaceans in Peruvian waters, this activity has yet to be developed.

Assessing and correcting for the effects of species misclassification during passive acoustic surveys of cetaceans [PDF]

, 2013
In conservation ecology, abundance estimates are an important factor from which management decisions are based. Methods to estimate abundance of cetaceans from visual detections are largely developed, whereas parallel methods based on passive acoustic ...

Defining humpback whale (Megaptera novaeangliae) potential distribution in the Great Barrier Reef Marine Park: a two-way approach

Context Humpback whale (Megaptera novaeangliae) populations have been recovering from whaling but are now facing threats from changing food availability due to ocean warming and changes in habitat suitability.

Humpback whale masked hearing thresholds in noise measured with modified behavioral observation audiometry

Communications Biology
Audiograms are available for multiple species of odontocetes (toothed whales). However, there are no empirically measured audiograms for any mysticete (baleen whale) meaning their hearing sensitivity is inferred.
