Book Description
The deployment of active sonar by the U.S. Navy and its potential impacts on marine mammals has been an ongoing issue of intense debate; regulatory, legislative, and judicial activity; and international concern. Some peacetime use of military sonar has been regulated under the Marine Mammal Protection Act (MMPA) and other statutes due to concerns that active military sonars are operated at frequencies used by some cetaceans (i.e., whales, porpoises, and dolphins), and their high-intensity sound pulses may travel long distances in the ocean. There is also concern that sonar transmissions of sufficiently high intensity might physically damage the hearing in cetaceans or cause them to modify their behavior in ways that are detrimental. Although mid-frequency sonar has been implicated in several beaked whale strandings, there is scientific uncertainty surrounding the totality of the effects active sonar transmissions may have on marine mammals. This report summarizes legal and political events related to active sonar and marine mammals since 1994. Prior to the late 1990s, concerns focused primarily on the use of underwater sound as a research tool. While strandings and mortality of marine mammals, primarily beaked whales, have been observed in concurrence with mid-frequency sonar operation, additional controversy has focused on the development of low-frequency active (LFA) sonar. Environmental interests are concerned with LFA sonar because low-frequency sound travels farther than mid-frequency sound and is closer in frequency to those known to be used by baleen whales. Additional questions involve how to balance obligations of the military to comply with MMPA provisions (as well as provisions of the National Environmental Policy Act and the Endangered Species Act) with national security concerns. Generally speaking, concern about the environmental effects of ocean noise is now principally focused on three activities -- military sonar exercises, oil and gas exploration, and commercial shipping. This report summarizes some of the more significant recent events pertaining to active military sonar, in particular.

Additional questions involve how to balance obligations of the military to comply with MMPA provisions (as well as provisions of the National Environmental Policy Act and the Endangered Species Act) with national security concerns. In 2003, Congress passed P.L. 108-136, wherein §319 amended the MMPA to authorize exemptions from restrictions on harassing and otherwise taking marine mammals for "national defense." Generally speaking, concern about the environmental effects of ocean noise is now principally focused on three activities -- military sonar exercises, oil and gas exploration, and commercial shipping.

Book Description
National security and environmental health have been at odds in America for decades. An example is the competing interests regarding Navy active sonar and marine mammal impacts. Navy sonar is essential for submarine detection, identification, and tracking. However, active sonar has been correlated to behavioral changes, deafness, hemorrhaging, stranding and death of marine mammals throughout the oceans. The U.S. Navy is currently proposing to increase active sonar testing and training off the Pacific Northwest coast in a range complex known as the Northwest Testing and Training (NWTT) Study Area. The Navy presently employs several marine mammal mitigation measure in order to limit negative impacts. However, additional mitigation measures exist that the Navy may utilize to further decrease harm. I have developed and evaluated five additional measures which support national security and environmental health. It is imperative the Navy assesses alternative mitigation measures that increase environmental protection while maintaining readiness standards.

Book Description
The Law Library presents the complete text of the Taking and Importing Marine Mammals - U.S. Navy's Atlantic Fleet Active Sonar Training (AFAST) (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 NMFS, upon application from the U.S. Navy (Navy), is issuing regulations to govern the unintentional taking of marine mammals incidental to activities conducted off the U.S. Atlantic Coast and in the Gulf of Mexico for the period of January 2009 through January 2014. The Navy's activities are considered military readiness activities pursuant to the Marine Mammal Protection Act (MMPA), as amended by the National Defense Authorization Act for Fiscal Year 2004 (NDAA). These regulations, which allow for the issuance of "Letters of Authorization" (LOAs) for the incidental take of marine mammals during the described activities and specified timeframes, prescribe the permissible methods of taking and other means of affecting the least practicable adverse impact on marine mammal species and their habitat, as well as requirements pertaining to the monitoring and reporting of such taking. This ebook contains: - The complete text of the Taking and Importing Marine Mammals - U.S. Navy's Atlantic Fleet Active Sonar Training (AFAST) (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure
