International Ocean Noise Coalition (IONC)

The IONC is a partnership of over 150 non-governmental organizations (NGOs) from around the world. This group was created to address the need for international action to combat the global impact of human-generated ocean noise on marine life. The Ocean Mammal Institute is an early member of the IONC.

Dr. Marsha Green, President/Founder of OMI, is the North American Ocean Noise Coalition (NAONC) contact.

Detailed information about OCEAN NOISE and International Ocean Noise Coalition (IONC) is maintained by The Animal Welfare Institute.

OMI ARCHIVE from 2005-2006:
IONC Opposes US Navy's Ocean Noise

The information below shows OMI's involvement with IONC in the early days of opposing the US Navy regarding two key issues about ocean noise.
(Links have been updated where possible as of March 19, 2016.)

The IONC has responded in writing to two issues that threaten to significantly impact marine life:

More information on each issue is listed below.

Issue 1: US Navy Undersea Warfare Training Range (USWTR)

The stated purpose of this sonar range is to train US Navy personnel on the use of active sonar to find, track and pursue submarines in the littoral or shallow zone. The Navy's preferred choice for the range is off the coast of central North Carolina. Its second and third preferences are Virginia, near Wallops Island, and the coast of Jacksonville, Florida.

According to the Navy's Draft Environmental Impact Statement (DEIS), the active sonar range:

  1. Will be the first of its kind in the world.

  2. Would be used as often as 161 times a year.

  3. Submarines from all three Eastern homeports - Norfolk, VA; Groton, CT; and Kings Bay, GA. - would use the range, as would war ships, helicopters and planes from various bases.

  4. The Navy envisions four scenarios for the range, the most extensive of which would involve two surface ships, two helicopters and a submarine

  5. The range would cover 500 square miles and would be outfitted with about 300 underwater microphones, or nodes

  6. Most exercises would not use live weapons; but once a year, each ship would be permitted to fire one anti-submarine rocket at a simulated target.

Two government agencies sent in written responses to the Navy's DEIS, the National Oceanic and Atmospheric Administration (NOAA) and the Marine Mammal Commission (MMC). The IONC also sent a written response. (See UPDATE below.)

Issue 2: US Navy SURTASS Low Frequency Active (LFA) Sonar Draft Supplemental EIS

The US Navy is planning to double the number of ships that will use SURTASS LFA. The Navy also plans to widen the geographic areas in which SURTASS LFA will operate, from a restricted region of the Pacific Ocean to broad ocean basins including the Atlantic, Pacific, and Indian Oceans and Mediterranean Sea. Navy's DEIS for LFA

The IONC response to the Navy's LFA EIS, along with other organization responses, are available in the UPDATE below.
