Marine Mammal Noise Exposure Criteria: Assessing the Severity of Marine Mammal Behavioral Responses to Human Noise

Aquatic Mammals, 2021
Major progress has been made since the publication of noise exposure criteria by Southall et al. (2007) in addressing the probability and severity of marine mammal behavioral responses to measured noise exposures.

Protection of Marine Mammals

2016
Within the European Defense Agency (EDA), the Protection of Marine Mammals (PoMM) project, a comprehensive common marine mammal database essential for risk mitigation tools, was established. The database, built on an extensive dataset collection with the focus on areas of operational interest for European navies, consists of annual and seasonal ...

Marine Mammal Species Classification using Convolutional Neural Networks and a Novel Acoustic Representation

ECML/PKDD, 2019
Research into automated systems for detecting and classifying marine mammals in acoustic recordings is expanding internationally due to the necessity to analyze large collections of data for conservation purposes. In this work, we present a Convolutional

The history of marine mammal bioacoustics at the Navy Marine Mammal Program

The Journal of the Acoustical Society of America, 2018
The United States Navy Marine Mammal Program (MMP) has been in existence for over 50 years. Following its inception, the program quickly became involved in the study of marine mammal sensory systems and bioacoustics. Early studies included the pioneering work of C. Scott Johnson in obtaining the first behavioral audiogram in a dolphin and Sam Ridgway’s

Morbilliviruses in marine mammals

Trends in Microbiology, 1995
Two of the three recently discovered aquatic morbilliviruses have been responsible for mass mortalities among marine mammals; both affect more than one host species, but susceptibility to infection varies considerably between species. Apparent differences between the dynamics of aquatic morbilliviruses and their terrestrial counterparts may be a ...

Estimates of Chinook salmon consumption in Washington State inland waters by four marine mammal predators from 1970 to 2015

, 2017
Conflicts can arise when the recovery of one protected species limits the recovery of another through competition or predation. The recovery of many marine mammal populations on the west coast of the United States has been viewed as a success; however ...
