Imagine the military visiting your hometown for special training exercises. Their activities wipe out your cell signal and keep your car from starting. Their exercises make so much dust and noise, you can’t hear, see, or think straight for days.

That’s okay right?

Probably not. Yet marine mammals have suffered equivalent disruptions to their daily lives during naval exercises for decades. The active sonar used in training exercises interferes with their primary guiding sense of hearing and causes them to flounder during simple tasks like feeding or navigation. As the exercises grow in size and sophistication, so does the extent of the damage they cause. Since marine mammals can’t defend themselves, several environmental organizations stood up to the government agency that’s supposed to defend them. Here’s what happened when environmentalists took on the government to save the whales, dolphins, sea turtles, and other marine animals.

Naval War Games Aren’t Games For Marine Mammals

The Navy strives to “maintain, train, and equip combat-ready Naval forces capable of winning wars, deterring aggression, and maintaining freedom of the seas.” The Navy makes sure it is capable of winning wars through training exercises, often called “war games.” Last year, the Navy planned a series of trainings classified as “military readiness activities” to occur over the next five years in the Hawaii-Southern California Training and Testing (HSTT) study area. A major downside of the trainings? They use active sonar that could potentially kill and injure the marine mammals living in the HSTT region.

Using active sonar just means you’re shooting sounds, called pings, into the water to listen for echoes. Sonar stands for “sound navigation and ranging” because the echoes returned from the pings help people and animals find and navigate around objects in their path. You can’t control the path of a ping; under water they spread out in ripples, touching everything in a given radius. This can get really noisy, really fast, as illustrated by this abstract rendition of sonar below.

If the ping hits a pile of rocks, no harm done. If the ping hits a marine mammal with ultra-sensitive hearing, it can interfere with their basic survival functions.

Marine mammals have evolved with an attuned sense of hearing that enables them to navigate through the murky undersea world, communicate with other animals, and even find food. Hearing is a marine mammal’s primary survival tool. So when military sonar pings rocket through the waves every few seconds, marine mammals can’t perform the most basic functions of life. Ships with sonar cause whales to stop eating and migrating like they should. If the animals get too close, sudden sounds can damage their life-giving hearing permanently and they could be perpetually disoriented forever. For humans, this would be like trying to walk, talk, and drive with continuously fogged-up glasses.

Even the vibrations from the sounds can cause damage under water. You know how the sound of many live drums can make it seem like your whole body is vibrating? Now imagine that times ten. When you hear on land, only your eardrums vibrate. Under water, sound waves rattle and penetrate your entire body. Intense noises–like those used in the naval trainings–can cause deadly hemorrhaging in marine mammals as powerful sounds penetrate their bodies.

This video shows how whales react to the screeching sounds of Navy sonar. They cluster closer to shore, stop diving for food, and change their swimming directions erratically. Some whales even beach themselves in an effort to escape the piercing sounds.

The Navy has been using active sonar in its trainings for years and environmental groups have fought it for almost as long. Past court rulings weighed the need to protect the public over the life of marine mammals. However, the Navy’s latest planned trainings in the HSTT area pushed the marine mammal death toll past levels evaluated in the past. The new exercise plan would include 500,000 hours of sonar, in other words, 500,000 hours of possible damage to marine mammals. According to this Washington Post article, the Navy’s own damage estimate stated 155 animals would die, 2,000 would be permanently injured, and 10 million would have their lives disrupted by the exercises. The Natural Resources Defense Council says this marks an 1,100 perecent increase when compared to other trainings from the past five years.

Armed with new facts and figures, the Natural Resources Defense Council, Cetacean Society International, the Animal Legal Defense Fund, and the Pacific Environment and Resources Center* brought forward a new lawsuit they hoped would succeed where similar efforts had failed in the past. Their case was named Conservation Council for Hawai‘i et al. v. National Marine Fisheries Service et al.

The Case

The plaintiffs didn’t go after the Navy itself, but the regulatory agency that approved the Navy’s training plan, the National Marine Fisheries Service (NMFS). Here’s a snippet from their mission page:

Under the Marine Mammal Protection Act and the Endangered Species Act, NOAA Fisheries works to recover protected marine species while allowing economic and recreational opportunities.

The Marine Mammal Protection Act prohibits the “take” (defined as “to harass, hunt, capture, or kill, or attempt to harass, hunt, capture, or kill) of marine mammals. When the Navy planned its new training exercises, it had to apply for an exception to this rule through NMFS. Their application outlined the potential death and injury counts, but the NMFS deemed those losses negligible. The attorneys on the case countered that the NMFS evaluation of the marine life damage neglected to grasp and acknowledge the full extent of potential damage caused by the Navy trainings.

The Endangered Species Act (ESA) calls for the government to protect endangered and threatened species. According to the Environmental Protection Agency, the “ESA requires federal agencies to ensure that any action they authorize, fund, or carry out, will not likely jeopardize the continued existence of any listed species, or destroy or adversely modify any critical habitat for those species.” Attorneys said the NMFS clearly neglected their duties under the ESA as many of the marine mammals found in the Navy’s massive HSTT study area are endangered.

The Verdict

U.S. District Judge Susan Oki Mollway ruled the NMFS had fallen short of its legal obligations to marine mammals by approving the Navy’s proposed training plan. She called the NMFS decision to refer to marine mammal damages from the naval exercises negligible, “arbitrary and capricious” and in violation of the Marine Mammal Protection Act. She also confirmed NMFS’s violation of the ESA, as eight of the thirty-nine marine mammal species living in the HSTT study area are endangered.

While the ruling affirmed the charges brought against the NMFS, specific remedies won’t be decided for the next few months. The decision marks a battle won, but it’s not quite the end of the war.

A Compromise?

The Natural Resources Defense Council released a statement from case attorney Zak Smith, summarizing what it hopes to get from the case:

The Navy has solutions at its disposal to ensure it limits the harm to these animals during its exercises.  It’s time to stop making excuses and embrace those safety measures.

Environmental groups aren’t asking for a complete cease and desist of all naval trainings involving active sonar. They’re just demanding the military use some of its extensive resources to develop safety measures to mitigate marine mammal damage. One option would be decreasing the test area size. Right now, the HSTT test area covers about 2.7 million square nautical miles, an area about the size of the entire United States. Another option is taking particular care to avoid areas where animals might be mating, giving birth, or feeding.

In the video above, Ken Balcomb from the Center for Whale Research says the Navy just needs to learn when and where to practice. He says just as the government would not test nuclear weapons in a crowded downtown area, they should not test active sonar in oceans teeming with delicate and endangered wildlife. For now, environmental groups remain optimistic that trainings and marine mammals can coexist safely.

The post Government vs. Environmentalists: Who is Protecting Marine Wildlife? appeared first on Law Street.

The global community is quickly working its way through the natural resources available to us. As we seek new ways to access oil and gas, one of the newest possible frontiers is the American Atlantic Coast. The U.S. has toyed with using a supposedly minimally invasive tactic to test for oil and gas deep in the Atlantic Ocean called airgun testing. Read on to find out what airgun testing is, what affect it has on the environment, and what its prospects are moving forward.

What is Airgun Testing?

Airgun testing is essentially a way to test for oil and gas reserves. The seismic airguns attach onto ships, and then blast loud, strong bursts of air onto the ocean floor. How the air responds can tell the airgun operator whether or not there may be oil or gas reserves below the surface. Watch the video below for a simple, technical explanation of how airgun testing works.

The History of Airgun Testing in the United States

On February 27, an Environmental Impact Statement was released by the Interior Department that allows the Bureau of Ocean Energy Management to begin issuing permits for seismic testing off the Atlantic Coast for oil and gas exploration. Although the ocean floor was tested for oil reserves in the 1970s and 80s, many experts feel those reports used outdated technology and gave an inaccurate representation of the oil and gas deposits in the Atlantic.

Some experts say that oil reserves could be found off the Atlantic coast that would be similar to those known to be in the Gulf of Mexico and could dramatically boost the American economy. Environmental groups, however, strongly oppose oil exploration using this method, as it is known to kill small fish and eggs in close vicinity to the air blasts. The long-term effects on the behavior of larger aquatic animals such as dolphins and whales is unknown. The proposed area for seismic exploration spans several miles off the coast and stretches from Delaware to Florida, and though the area in question is banned from any oil exploration activity until 2017, the next president could overturn that rule.

What are the arguments in favor of airgun testing?

Advocates of oil exploration off the Atlantic Coast using airgun seismic testing argue that the permits issued by the Bureau of Ocean Energy Management (BOEM) place restrictions that will make airgun testing safe for marine wildlife. The Environmental Impact Statement recommends three restrictions to ensure that these tests are conducted in a safe, environmentally conscious manner:

1. Prohibit survey activity on the migratory routes of the endangered Right Whale. A path roughly 20 miles wide would be created in the middle of the proposed area in which exploration could not be conducted from November through April — the whale migration season — creating a safe corridor for the whales.
2. Prohibit more than one survey from being conducted at any given time.
3. Prior to any survey activity, exploration vehicles would be required to use passive acoustic monitoring systems to identify wildlife in the exploration area; if any wildlife are found that would be affected by the airgun, the survey area for that day would be shifted to a different location.

Advocates feel that these provisions, written into any permits issued by the BOEM, would safeguard against potential negative effects of airgun testing.

Advocates also point to the economic benefits of updated oil exploration off the Atlantic Coast. Some experts claim that the Atlantic coast could hold the equivalent of seven years of oil generated in the Gulf of Mexico, enough to boost the American economy and strengthen the United States’ energy security. The American Petroleum Institute has estimated that the oil to be found there could generate nearly 280,000 jobs, $195 billion in private revenue, and $51 billion in government revenue.These estimates, of course, are dependent upon the discovery of more oil than the current 3.3 billion barrels estimated to be there. Additionally, supporters argue that airgun testing can also be used for tasks such as discovering sand deposits for beach recovery and as scouting for possible locations of off-shore wind turbines.

What are the Arguments Against Airgun Testing?

Opponents argue that the Bureau of Ocean Energy Management has been too hasty in its approval for permits without proper studies of the long-term effects of airgun testing on marine wildlife. It is known that the high pressure airgun blasts can injure or kill small fish and their eggs, but little is known about the long-term effects on marine animals such as behavioral disruption, migration, and mating patterns. The area up for seismic testing puts 34 species of whales and dolphins and several species of turtles at risk. Because sound travels faster in water, aquatic wildlife miles away from the seismic testing could be affected, although the effects of airgun testing are still being studied. Environmental group Oceana argues that the November through April ban on seismic testing will not save the whales and that the BOEM did little to use current acoustic data on whale activity or search for alternatives methods to airgun testing.

Airgun testing in the Atlantic has also sparked backlash because it could potentially harm tourism and fishing industries in coastal areas, in addition to the negative effects of offshore oil production that are sure to result from oil exploration. Opponents point to the results of airgun testing off the coast of Southwestern Africa, which severely disrupted tuna migration patterns, and thus damaged the tuna industry that normally thrives in that area.

Some experts argue that while 280,000 jobs in oil exploration and production could be created, some 730,000 jobs in the fishing and tourism industries would be lost if oil exploration were to disrupt aquatic wildlife. Additionally, opponents argue that oil exploration will inevitably progress to oil production, which could have disastrous effects upon the Atlantic coast. The effects are still felt today of the 2006 Deepwater Horizon oil spill in the Gulf of Mexico and the Exxon-Valdez oil spill near Alaska in 1989. The same type of oil spill could potentially occur off the Atlantic coast if drilling were permitted there, which runs the risk of affecting a greater population than either of the previous spills. Oil drilling itself could pose a myriad of negative effects upon marine wildlife, and airgun testing could be blamed for paving the way to large-scale offshore oil drilling near the Atlantic coast.
