Giant Squid Killed by Sonar, it Looks Like a Dead Alien

The poorly restricted and out of control use of sonar and underwater explosives is destroying everything from invertebrates to whales.  While nations quarrel over shrinking fisheries, the world’s navies are turning the ocean into a sonic soup.

Giant Squid Mystery Solved? Published May 3, 2011 for National Geographic.

In the early 2000s the remains of giant squid were found off Spain’s Asturias province (map). In each case, the creatures’ bodies appeared soon after ships had used air guns to conduct low-frequency sound-pulse exercises in the region, in some cases for oil-and-gas prospecting efforts.
Scientists investigating the giant squid remains at the time found evidence of extensive bodily damage, including mantles reduced to pulp, bruised muscles, and lesions in statocysts. These fluid-filled organs rest behind the creatures’ eyes and help giant squid maintain balance and position. (See pictures of a colossal squid dissection.)
At the time, marine biologist Angel Guerra speculated—but was unable to prove—that noise from prospecting ships was harming cephalopods and other marine life.
“With this study, we now have proof” that low-frequency sounds can harm cephalopods, said Guerra, a marine biologist at Spain’s Marine Research Institute who was not involved in the current study, which will appear in a future issue of the journal Frontiers in Ecology and the Environment.

This is a world wide issue, and the logical place to look for solutions is the United Nations.  Below I have copied some information with links, in hopes that someone (you!) will start a unified approach to the problem of sonar and explosives in the ocean.  Please keep me informed of any efforts.

From the UN Global Issues – Environment page:  “In view of the crucial importance of the environmental perspective and the principle of sustainability, the General Assembly has declared a number of observances to catalyze positive action worldwide.
Among those currently in effect are the United Nations Decade of Education for Sustainable Development (2015-2014), and the International Decade for Action, “Water for Life”, which began on 22 March 2005.  In addition, the world community will observe the International Year of Natural Fibres in 2009, the International Year of Biodiversity in 2010, and the International Year of Forests in 2011.
Annual environment-related observances declared by the Assembly also include World Water Day (22 March), the International Day for Biological Diversity (22 May), World Environment Day (5 June), World Day to Combat Desertification and Drought (17 June), International Day for the Preservation of the Ozone Layer (16 September), International Day for Preventing the Exploitation of the Environment in War and Armed Conflict (6 November), and International Mountain Day  (11 December).”
