Active Military Sonar and Marine Mammals:
Events and References
Summary
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. 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. This report summarizes some of the more
significant recent events pertaining to active military sonar, in particular.

Active Military Sonar and Marine Mammals:
Events and References
Introduction
The Marine Mammal Protection Act of 1972 (MMPA; 16 U.S.C. §§1361, et
seq.) established a moratorium1 on the taking of marine mammals in U.S. waters and
by U.S. nationals on the high seas. Under the MMPA, take means “to harass, hunt,
capture, or kill, or attempt to harass, hunt, capture, or kill.”2 In addition, harassment3
encompasses both behavioral disruption and physical injury, short of death.
However, the MMPA does allow U.S. citizens to apply for and obtain authorization
for taking small numbers of mammals incidental to certain activities (e.g., offshore
oil and gas exploration and development), if that taking would have no more than a
negligible effect on any marine mammal species or stock, and mitigation and
monitoring requirements and other conditions are met.
Some peacetime use of military sonar has been regulated under the MMPA and45
other statutes due to concerns that active military sonars operate at frequencies used
by some cetaceans6 and may travel long distances in the ocean. Current sonars in
widespread use are primarily mid-frequency sonars. Mid-frequency active sonar
operates between 2 and 20 KiloHertz (KHz), with most current systems using 3-5
KHz and 7-10 KHz. Low-frequency sonar is being developed to detect quieter
submarines at greater distances.7 Low-frequency active (LFA) sonar operates below

2 KHz, with most operation between 600 and 1500 Hz, except the U.S. Navy’s


1 Although the MMPA (16 U.S.C. §1371) refers to this action as a “moratorium,” some
consider this action a ban or prohibition because it was (and is) permanent.
2 16 U.S.C. §1362(13).
3 16 U.S.C. §1362(18).
4 Active sonar involves the transmission of various sounds (pulses, tonal signals, or bands
of acoustic energy) and the interpretation of received echoes as a way of sensing the
environment. Passive sonar involves listening without transmitting these sounds. Non-
military active sonars, such as the Integrated Marine Mammal Monitoring Protection System
(IMAPS) active tracking system and high-frequency bathymetric mapping sonars, are not
the primary focus of this report.
5 Frequency is expressed as the number of cycles or completed alternations per unit time of
a sound wave, most often measured in Hertz (Hz).
6 Baleen whale sounds are usually below frequencies of 500 Hz and predominantly below
100 Hz; exceptionally some clicks can reach 3000 Hz. Toothed cetaceans, such as sperm
whales, beaked whales, dolphins, and porpoises, are characterized by their higher frequency
sounds, from 400 Hz to as high as 8000 Hz.
7 The U.S. Navy committed to developing a low-frequency active sonar system in the late

1980s.



Surveillance Towed Array Sensor System (SURTASS) which operates between 100
and 500 Hz. When the transmission power is sufficiently high in intensity,8 there is
concern that sonar transmissions could physically damage the hearing in cetaceans
or cause them to modify their behavior in ways that are detrimental to their well-
being, invoking the requirements of the MMPA moratorium on taking. 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 administrative, legal, and political events related to
active sonar and marine mammals. Prior to the late 1990s, concerns focused
primarily on the use of underwater sound as a research tool.9 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 LFA sonar. Environmental interests are concerned with LFA
sonar because low-frequency sound travels further than mid-frequency sound and is
closer in frequency to those known to be used by baleen whales. Additional
questions involve how to balance the 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

8 Sound intensity is measured in decibels; a decibel (dB) is a unit used to express the
intensity of a sound wave, equal to 20 times the common logarithm of the ratio of the
pressure produced by the sound wave to a reference pressure (typically 1 micropascal at 1
meter, in water; 20 micropascals at 1 meter, in air). Thus, direct numerical comparisons of
noise intensity from sources in air and sources underwater cannot be made without taking
into account the differences in reference pressure. For example, a sound intensity of 235
dB underwater is equivalent to 209 dB in air. For additional background, see [http://www.
