- The World of Sound. Crocker, Malcolm J. // International Journal of Acoustics & Vibration;Jun2013, Vol. 18 Issue 2, p50
The article discusses papers published within the issue, including "Sound in the Ocean: Acoustical Interactions With Marine Animals," by Mardi Hastings and "Numerical Prediction of the Signature of Maritime Platforms," by Nicole Kessissoglou.
- Errata. // Aquatic Mammals;2013, Vol. 39 Issue 2, p205
Corrections to the article "A Review and Inventory of Fixed Autonomous Recorders for Passive Acoustic Monitoring of Marine Animals," by Renata S. Sousa-Lima and colleagues, from pages 23-53 in the 2013 issue of the journal "Aquatic Mammals" are presented.
- Surround Sound. Rizzo, Johnna // National Geographic;Sep2012, Vol. 222 Issue 3, following p24
The article presents information about a technology developed by University of Texas acoustic scientists which uses bubble-like air pockets to surround underwater machinery such as drilling rigs in order to reduce the noise they transmit and thereby aid communication by ocean animals.
- Inside Out Acoustic Monitoring. Smith, Victoria // Journal of Ocean Technology;2014, Vol. 9 Issue 1, p102
The article provides a comparison between active acoustic monitoring (AAM) and passive acoustic monitoring (PAM). The AAM and PAM systems are compared in terms of their capability for monitoring non-vocalizing mammals, their effectiveness for short-term and long-term studies of marine animals,...
- underwater sound. Indle, Christ T. // New Zealand Science Teacher;2009, Issue 121, p10
The article focuses on the detection and measurement of underwater sound. Underwater microphone, called hydrophone, is used to detect underwater sound. It is noted that many marine animals are using underwater sound to find their prey. Echo sounders are developed to measure the depth of water. A...
- NATURAL RESOURCES DEFENSE COUNCIL, INC. V. WINTER. Gross, Andrew // University of Baltimore Journal of Environmental Law;Fall2007, Vol. 15 Issue 1, p81
The article discusses a court case wherein the complainant, the Natural Resources Defense Council asked the U.S. Court of Appeals for the Ninth Circuit for an injunction to protect whales, dolphins, and other marine mammals. The Court issued an injunction on grounds that the U.S. Navy failed to...
- UN recognizes dangers of ocean noise. // Earth Island Journal;Summer2006, Vol. 21 Issue 2, p14
The article reports that the International Ocean Noise Coalition (IONC), under the coordination of Dr. Marsha Green of the Ocean Mammal Institute, successfully lobbied the UN Law of the Sea. From the work of the IONC, of which International Marine Mammal Project is a founding and active member,...
- Ocean Noise: Making Sense of Sound. André, Michel // Journal of Ocean Technology;2014, Vol. 9 Issue 1, p34
The article examines the impact of man-made noise on marine animals' physical health and use of sound. Topics discussed include the challenges in assessing the acoustic impact of artificial sound sources in the marine environment, the Marine Strategy Framework Directive (MSFD) adopted by the...
- Ocean Commotion. Kessler, Rebecca // Natural History;Nov2006, Vol. 115 Issue 9, p14
The article discusses research being done on the increase in the low-frequency noise from ships by ten decibels. It references a study by Mark A. McDonald et al, published in the 2006 issue of the "Journal of the Acoustical Society of America." In the 1960s the U.S. Navy recorded ambient noise...
