Estimating received level in behavioral response studies through the use of ancillary data.

Marine mammals are known to respond to various human noises, including and in certain cases, strongly, to military active sonar. Responses include small and short-term changes in diving behavior, horizontal avoidance of an ensonified area, and mass strandings. Considerable research has been conducted using short-term biologging tags to understand these responses.

Acoustic signature of plastic marine debris mimics the prey items of deep-diving cetaceans.

It is largely assumed that odontocetes voluntarily ingest plastic marine debris because they visually mistake it for prey. However, deep-diving whales do not rely on visual systems to forage and instead employ echolocation. Whether or not these whales misinterpret acoustic signals that lead to the accidental ingestion of plastic is unknown.
