People who want to watch marine mammals like dolphins often head to
theme parks such as SeaWorld. But after a killer whale at one SeaWorld
killed its trainer last month, critics are calling for a reevaluation
of keeping these huge animals captive. Ann Dornfeld has the story.

In the wild, a killer whale’s world sounds something like this:

[Killer whale calls in British Columbia]

But most people see killer whales in an environment like this:

[Electric guitar at SeaWorld show, chanting of “Shamu! Shamu!
Shamu!”, audience claps in time]

SeaWorld calls all of its performing whales “Shamu.” Millions of
people have visited SeaWorld over the decades to get splashed by
Shamu’s tail and watch trainers leap off the killer whales’ noses. The
trainers hug and kiss the animals between high-flying stunts.

But animal rights activist Will Anderson says there is nothing healthy
about the relationship between captive marine mammals and their
keepers. The waters around Seattle, where he lives, are home to wild
killer whales. Anderson has worked to free captive killer whales for
40 years.

“The relationships they have with their trainers are
nothing less than ‘Well, what else is there to do?’ If you’re starved
for what you innately need – social bonding – you’re gonna settle for
whatever morsel you can get.”

Killer whales are actually huge dolphins, not whales. Anderson says
tanks are no place for animals which roam up to 100 miles each day in
their native waters.

“Their bodies and their minds, and their behaviors,
their needs and their huge size, they are all adapted for the wild.
They are not adapted for tanks.”

At SeaWorld, Julie Scardina is the Animal Ambassador. She handles
public relations for the theme park. She says just because killer
whales can roam 100 miles a day in the wild doesn’t mean they often
do.

“The 100 mile statistic there is actually just a
capability. They have the capability of roaming that far, just like
humans have the capability of walking 20 miles or more per day. We
provide opportunities for exercise, for play, and of course during our
shows they get plenty of exercise.”

Scardina used to train killer whales. She says the tricks show the
public what the animals are capable of. And she says keeping killer
whales in a more naturalistic, aquarium-like environment wouldn’t
serve the animals well.

“I’ve worked with animals for over 30 years. There’s
no way you can convince me that it would be better to let an animal
kind of hang. That’s kind of like saying it’s okay to let a person sit
on the couch if they’d like. You need to provide stimulation, you want
to get them up and moving.”

Scardina says the goal of SeaWorld’s Shamu shows is to encourage
marine conservation.

“Well, certainly our mission is to educate people
about the oceans, to inspire them. And that’s what obviously our hope
is, is by seeing these animals and how incredible they are – I know
that’s how I became inspired when I was a child.”

But in a promotional video for SeaWorld’s main killer whale show,
called “Believe,” SeaWorld employees suggest a different theme… more
conquest than conservation.

“How do we get in the water with the top predator in the ocean, y’know. that kills and eats anything it wants at any time.
I thought for a moment right there, y’know what, this is really crazy
what we do. But we are doing it!”

The video, and the “Believe” show itself, focus on the power of the
human spirit – not the marine environment.

Activists like Will Anderson are calling for theme parks like SeaWorld
to return killer whales to their native waters, protected by huge
enclosures. There is general agreement that captive killer whales
wouldn’t survive if released into the open ocean.

A new federal ruling could
protect marine animals by
changing how and where
the Navy uses sonar. Samara Freemark reports:

Critics of sonar say it’s so loud that it confuses whales and other marine animals, and can cause them to be injured or even die. That’s why environmental groups have been pushing for tighter regulations on the technology.

This week the National Oceanic and Atmospheric Administration, or NOAA, took a step in that direction. The agency acknowledged that current policies are not doing enough to protect marine mammals. And NOAA says it will identify critical marine habitats impacted by sonar.

Michael Jasny is a policy analyst with the environmental group the Natural Resources Defense Council. He hopes the policy will be a first step to banning sonar in those habitats.

“It’s not a prescription, it’s a plan. And it sets in motion potentially a very significant change. I mean, the proof will be in the pudding, of course.”

Jasny says his organization will work with NOAA and the Navy to negotiate sonar policy so that marine mammals are not hurt.

The Case of the Disappearing Dolphin

  • A false killer whale, which is actually a type of tropical dolphin, with calf (Photo by Deron Verbeck, courtesy of iamaquatic.com)

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Transcript

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Jim Cook has been a fisherman in Hawaii for 18 years.

“You know, it used to be real simple: catch a fish, sell it, and go
back out and try and catch another one.”

Now he owns a company that operates six fishing vessels. Cook’s
ships catch deep swimming sashimi-grade tuna that ends up in sushi
restaurants across the US. They use a technique called longline fishing.

“We have around 45 miles of mainline to which we attach floaters
and 2200 to 2500 baited hooks.”

“The regulations imposed on the Hawaii longline fishery are
probably the most restrictive regulations on any longline fishery in the
world.”

That’s Bill Robinson. He’s an administrator with the National
Marine Fisheries Service. And these regulations he’s talking about are
meant to reduce bycatch. That means catching marine animals other than
the tuna. As a result of these policies, sea turtle bycatch has dropped
by more than 90-percent and seabird bycatch by 95-percent.

Things are looking up, but now there’s another problem. The numbers of
another kind of animal – the false killer whale – are declining. No one
knows why they’re disappearing. It might be related to longline
fishing, but it’s just not clear.

Robin Baird’s a biologist with Cascadia Research.

“There’s a whole variety of lines of evidence that imply the false
killer whale population around the main Hawaiian islands has declined
dramatically over the last 20 years. And I think it’s clearly the most
serious conservation or management issue for whales and dolphins in
Hawaiian waters today.”

Baird thinks the decline is partly related to fewer numbers of tuna
and other species false killer whales eat. He also suspects that the
false killer whales might be moving farther offshore, where they could
get hooked when trying to eat the tuna caught by the longline fishery.

So the question is: should the National Marine Fisheries Service come up
with even more regulations for the longline fishery in case more false
killer whales move offshore looking for tuna.

Bill Robinson with the Fisheries Service isn’t so sure that they
actually go that far offshore.

“That’s speculation, and it may or may not be true. What we
don’t really know is what the range of each population is.”

So, really, at this point, it’s anyone’s guess why the false killer whale numbers are declining.

The biologist, Robin Baird, is concerned that nothing’s being done.

“Unless something is done to change the factors that are
influencing the population, it probably will continue to decline.”

The environmental group Earthjustice and a coalition of
conservation groups have sued the National Marine Fisheries Service over
failing to develop a plan to protect the false killer whales.

The agency has not responded officially to the lawsuit yet. But Bill
Robinson says an action plan is in the works.

“Hopefully by the fall, we’ll be able to not only appoint the
team, but have the team begin work on a take recovery plan that will
make recommendations to the agency to reduce the incidental take of
false killer whales in the fishery.”

Such a plan might end up costing the commercial fishers money. But
Jim Cook says he’s willing to pay. That’s because false killer whales
pick fish off his lines. They eat the caught tuna before the fishers
can haul them in. That can mean a lot of lost income.

“We would very much welcome any methodology almost
irrespective of cost because we’re suffering quite a bit economically as
it is.”

But the National Marine Fisheries Service first has to find that
methodology.

Rare Right Whale Recorded

Scientist think they’ve found
a rare whale in a place where
they thought they were wiped
out. Sadie Babits reports,
they haven’t seen the whale
but they’ve heard it:

Scientists thought the North Atlantic Right Whale
was gone. Only two of them have been spotted in
the last 50 years off the southern tip of Greenland.

But some underwater microphones picked up right
whale calls.

“They sound like mmmmmmick… kind of like that.”

That’s David Mellinger. He teaches at Oregon State
University.

He says they recorded more than two
thousand right whale calls in a year. That doesn’t
mean there are a lot of the whales, but Mellinger
says hearing any in the North Atlantic is significant.

“Because the population is so endangered. There
are only 300-350 maybe right whales in the world.
So finding any new whales is important.”

But there is a concern. As the Arctic Ice Cap
melts because of global warming, more ships are
expected to pass through the area. That could
mean ships could strike and kill the few right
whales that are left.

It’s been rough sailing for a Superferry that transports passengers and vehicles around the Hawaiian Islands. A lot of people who live in Hawaii, as well as businesses and tourists, depend on the Superferry. But there’s been a lot of concern about the ferry’s impact on the environment. Heidi Chang reports the Superferry is now suspending its service. The last voyage will take place today:

Back in 2007, Hawaii legislators passed a special law that allowed the Superferry to sail between Oahu and Maui, before an environmental study was completed. The Hawaii Supreme Court has ruled that’s against the law.

Robert Harris is the director of the Sierra Club. It’s one of the groups that challenged the Superferry and the state in court. He’s worried about the impact it might have on traffic and that natural resources could be taken without better oversight.

“One of the first days of operation, some people on Oahu drove a truck over to Maui and loaded up on a bunch of river rocks, and were transporting it back to Oahu, and they were fined, I think significantly for that.”

Harris says the environmental review will also look at whether the ferry might be disturbing whales or transporting invasive species that could endanger native plants and animals.

Opening Up New Waters for Whale Hunts?

Japan kills more whales than any other country in the world. A new proposal would allow Japanese whalers to hunt off their county’s coasts. Mark Brush reports – some think opening up these waters to whale hunts is a bad idea:

The International Whaling Commission passed a moratorium on commercial whaling in 1986. But it allowed some countries to kill whales for what it calls scientific study.

Japanese boats kill hundreds of minke whales in the southern ocean under this designation. Critics say there’s nothing scientific about these hunts.

Now, the Commission wants to stop Japan from killing whales in the southern ocean. Phasing out these so-called scientific whale hunts. But in exchange, they might let the country openly hunt whales off its own coasts.

Jonathan Stern is with the American Cetacean Society. He says whale populations could take a hit, if Japan is allowed to start hunting in these waters:

“I’m just afraid once their fleet starts operating. They’re going to want to take more whales and more different species of whales.”

Japan has long maintained that these hunts are part of their cultural heritage. The International Whaling Commission will meet next month to decide the issue.

Noisier Oceans Bad for Whales

Scientists say the oceans are
getting noisier. The racket threatens
whales and other marine mammals that
communicate through sound. Nancy
Greenleese reports:


The oceans are already noisy from military sonars and oil and gas exploration. Scientists say it could get worse. Some of the greenhouse gas, carbon dioxide, is getting soaked up by the oceans and seas. The carbon dioxide makes the water more acidic. Sound travels through that acidic water more easily. A UN climate change panel recently issued a report raising concerns about the chemistry change. Mark Simmonds of the Whale and Dolphin Conversation Society says already there’s an “acoustic fog” in the world’s waters.

“The ambient noise levels in the oceans because of pH are likely to rise. This is a very unexpected finding. They’re anticipating that marine mammals will have further problems communicating.”

The noise confuses marine mammals. So, they’re beaching themselves and running into ships more often.

Environmentalists have wanted to
“Save the Whales” for decades. But experts
say that can’t happen until the people
realize whales don’t know if they’re in
American waters, Mexican waters or Japanese
waters. Nancy Greenleese reports whales
cannot be saved until all countries protect
them:

Whales travel off many countries’ coasts and different countries have different laws
about protecting the animals. Chris Butler Stroud is with the Whale and Dolphin
Conservation Society. He told a United Nation’s conference for the Convention on
Migratory Species that international cooperation is key.

“When countries try to take political action to conserve an animal, they often think of
their own borders. Not remembering that animals are able to move beyond those because
they don’t see the lines in the sand or lines in the water.”

(sound of Gray Whales splashing)

Gray whales swarm around fishing boats off Mexico’s Baja California peninsula.
They’ve traveled -without passports – from the Bering Strait in Russia, into U.S. waters,
through Canada, and back into the U.S. before arriving in Mexico. Here they’re
breeding, and providing a water show to rival Sea World for ecotourists.

“Oh…it’s the baby. Right there! Right next to us. And here comes mom! (Splash) Hey,
wow, right at us.”

There’s an international agreement that bans commercial hunting for gray whales. And
the whales draw tourists. That’s pretty important for a poor country such as Mexico.

The whales are safe here, but not everywhere.

And everywhere the whales travel and threat looms: climate change. Many whale species
migrate to the poles where the ice is disappearing. The World Wildlife Fund predicts
30% of the ice will melt away in the next 30 years unless action is taken.

Wendy Elliot says that means the whales will have to travel even farther to get to the ice
and the food they find there.

“So they’re already hungry, tired, they’ve traveled a long, long way and now they are
going to have 500 km extra to go. So how these species are going to adapt is very
unclear and it’s very concerning.”

Another worry is the growing acidity of sea water. Greenhouse gases from burning fossil
fuels mix with the water and make carbonic acid in the ocean. Monterey Bay Aquarium
Research Institute chemists have determined that the altered chemistry will increase the
distances that underwater sounds travel. That disturbs the communications of marine
mammals. The oceans and seas are becoming a headbangers’ ball from rumbling ships,
air guns used for oil and gas exploration and military sonars.

Nicolas Entrup, managing director for the Whale and Dolphin Conservation Society,
lobbied at the UN meeting for an international resolution on marine noise pollution.

“Look, we stressed to the governments that underwater noise is a key threat to whales and
dolphins in the ocean. These animals are acoustic animals.”

The Whale and Dolphin Conservation society says research shows loud underwater
noises causes some whales to beach themselves.

At the UN conference, nations passed watered-down resolution to reduce ship sounds.
They did nothing about the noises made by oil and gas industry and the military. Entrup
is furious.

What we’ve passed is absolutely not enough. And I have to say it’s giving in to the
interests of the military and the industries in that occasion. That’s really bad.”

Officials admit that industrial noise can be reduced but the military, that’s another matter.

The 85 governments at the U.N. conference did agree to provide addition protection for
some small whales. But putting any initiatives into effect will be difficult. The global
financial crisis has drastically limited countries’ contributions to field research on whales
and other migratory species. Entrup with the Whale and Dolphin Conservation Society
says the nations of the world cannot ignore the problems.

“If you care, then start now and do not wait until it’s too late. That’s expensive, that’s
irrational, that’s stupid.”

Wildlife groups say rich countries have to reach across borders and give a hand to poorer
countries if we’re going to save the whales.

Sea of Controversy for Hawaii’s Superferry

  • Hawaii's Superferry was met with initial excitement, but it quickly turned to environmental concern (Photo courtesy of Hawaii Superferry)

For decades, people who wanted to get from
one Hawaiian island to another have had one main
option: flying. So when plans were unveiled for
a high-speed ferry between the islands, Hawaiians
and tourists were initially thrilled. But growing
concern about the Superferry’s potential environmental
impact has turned the issue into one of the state’s
biggest legal battles in years. Ann Dornfeld reports:

For decades, people who wanted to get from
one Hawaiian island to another have had one main
option: flying. So when plans were unveiled for
a high-speed ferry between the islands, Hawaiians
and tourists were initially thrilled. But growing
concern about the Superferry’s potential environmental
impact has turned the issue into one of the state’s
biggest legal battles in years. Ann Dornfeld reports:

David Dinner is board president of the environmental group 1000 Friends
of Kaua’i. He lives near this small beach on the island’s north shore.
Dinner says when endangered humpback whales come to Hawaii in the
winter to give birth, you can whale-watch right from this beach. Even
when he lived far from the ocean, he once witnessed a huge migration
from his window.

“I could see that the ocean was filled with whales. And I later found out that there were 6,000 whales around Kaua’i at that
time. So it was like wall-to-wall whales out there.”

When Dinner first heard about plans for a high-speed inter-island
catamaran, he was excited. But the more he and others learned about the
Hawaii Superferry, the more they worried about its effect on those whales.

Mother whales spend a lot of time just below the surface, pushing their
calves up for air. The concern is that the ferry’s twin hulls would strike the
whales at a speed of up to 45 miles per hour. That’s a lot faster than other
boats like cruise ships and tankers.

“The other boats that travel in this area generally go in the area of 13 to 15
miles an hour. So the Superferry is way beyond the speed of the other boats.”

Another big worry was that the car ferry could bring invasive species from
one island to another. For instance, mongooses decimated the Big
Island’s bird population. But Kaua’i doesn’t have mongooses yet.

Rich Hoeppner is founder of the Superferry Impact Group.

“We have an incredible selection of birds here. We have shearwaters,
albatross, the state bird – the Nene, is a land-dweller and endangered
species. So one pregnant mongoose gets on our island, our bird
population will be history.”

When activists learned that the state government had given Hawaii
Superferry the green light without an environmental impact statement,
they filed suit. Last August, the state Supreme Court ruled that the state
should have required an environmental impact statement.

Despite that, just two days later, Superferry made its maiden voyage to
Kaua’i.

Rich Hoeppner says two dozen surfers and kayakers blocked the
boat’s path to Nawiliwili Harbor for hours.

The next night, protesters crowded the harbor, and dozens more people
took to the water – some in traditional Hawaiian canoes. Protesters
filmed the action.

(sound of protest chants)

“After 3 hours, the ferry, which was at the mouth of the harbor, turned
around and went back to Oahu. It didn’t get to its dock. And it hasn’t been
back since!”

Hawaii Superferry says it takes the environment seriously.

Terry O’Halloran is Director of Business Development. He points to the
company’s efforts to keep invasive species from hitching
a ride on vehicles.

“We look under the hood, we look in the trunk, we look in the wheel wells,
we look inside the vehicles, and then a certain number of vehicles that go
through our security screening get a much more thorough screening and
inspection.”

O’Halloran says vehicles with muddy tires aren’t allowed on board in case
bugs or seeds are in the dirt. There are boot scrubbers for passengers,
too. On-board videos warn travelers about the dangers of invasive
species.

O’Halloran says Superferry also has a Whale Avoidance Policy that
includes avoiding the main calving areas during whale season, and
slowing down in whale zones.

“We have been able to spot and avoid the whales. We also have two dedicated
whale lookouts and their only job is to help the captain spot whales.”

Superferry is still making its Oahu-to-Maui trips. In a special session,
Hawaii legislators passed a law allowing the Superferry to keep
running while the state conducts an Environmental Impact Statement.

Protestors say that’s a terrible idea – and illegal. They’re pursuing
lawsuits in the state Supreme Court to dock the ferry until it’s clear the
boat is safe.

For many people orca whales are very
familiar. Think Shamu. We’ve even given the wild
killer whales of the Pacific Northwest individual
names. But there’s still a lot we don’t know, like
where the whales go and what they eat. Now that they’re
listed as endangered, those have become important
questions. Liam Moriarty accompanied a research
crew trying to get answers:

Killer whales are sloppy eaters, so one way to study their diet is to
scoop up the leftover crumbs. Robin Baird says another way is to
study what comes out the other end.

“And so we basically follow behind the whales and pick up whatever
they leave behind, so either bits of fish if they’re actually catching
prey, or fecal material which we can use to look at what they’re
feeding on using genetic analysis.”

Baird is a biologist with Cascadia Research in Olympia, Washington.

(outboard motorboat sounds up)

On this morning, Baird, biologist Brad Hanson, and several other
researchers are piled into a 19-foot inflatable boat. We’re heading out
from Friday Harbor, north of Seattle to look for whales. We head
toward the Canadian border, keeping our eyes peeled. A while later,
we locate a group of more than a dozen whales.

(boat slows down)

Now comes the tricky part. The game plan is to pick an animal to
follow, and hope it leaves a specimen in its wake.

Baird: “We’ll come along side this one, get an ID then we’ll start a
flukeprint on her.”

Whales are surfacing and diving all around us.

(whale exhalation)

Researchers call out sightings, directions and distances …

“Multiple targets. Two animals. (How far?) 100 meters.”

Robin Baird maneuvers the boat into the wake of a passing whale.

“Oh, fish in mouth! Eleven’s got … the male’s got a fish in mouth!”

Researcher Greg Shorr stands in a pulpit at the bow of the boat with
a long handled pool net, looking intently into the water for the telltale
glitter of fish scales.

“OK, dip!”

He dips the net and comes up with a few scales and bits of tissue.

(whale breath)

Soon we’re tracking other orcas.

Hanson: “Chase! Underwater chase, 12 o’clock! Another target up,
125 behind us at 5 o’clock … might be chasing something … Yep!
Definitely chasing something! Two animals back there, three
animals!”

We spend over an hour tailing whales and dipping pool nets that
mostly come up empty.
(whale breath)

Getting this up-close and personal with the whales would get anyone
who doesn’t have a federal research permit ticketed for whale
harassment … But this kind of work is one important way to get
information that could help save the orcas from extinction.
Eventually, the whales move on. We make the long trip back.

(boat motors up, fades)

(brewpub noise)

That evening, in a dockside brewpub, Brad Hanson and Robin Baird
reflect on the day’s work; twelve hours on often-choppy seas. Baird
says that’s what it takes to get close to the whales.

“If we want to be able to really understand what they’re doing, we
have to be able to see the fine details of their behavior. And the only
way we’re going to se those fine details is if we’re actually close
enough to see whether a whale has a fish in its mouth when it comes
up to the surface.”

Hanson says that approach is paying off.

“Some 30 years we’ve known all these individual animals and people
have spent a lot of time looking at them, but we are seeing things in
the last couple of years that other people have not seen.”

For instance, orcas sometimes play with their food or share prey with
each other. Analysis of fecal samples has pinpointed what kinds of
fish the whales eat, and when. Observations like these have given
researchers a better picture of how the animals interact with their
habitat. And that fills in a few more pieces of the puzzle they hope will
lead to recovery for the Pacific Northwest’s endangered killer
whales.
