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:

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.

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

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.

Part 1: Tidal Power in the Pacific

For decades, people in the Pacific Northwest have relied on hydropower
for most of their electricity. But dams hurt salmon runs and river
ecosystems. That’s sent Washington utilities on a quest for new, cleaner
sources of power. As Ann Dornfeld reports, some are looking for new ways

For decades, people in the Pacific Northwest have relied on hydropower
for most of their electricity. But dams hurt salmon runs and river
ecosystems. That’s sent Washington utilities on a quest for new, cleaner
sources of power. As Ann Dornfeld reports, some are looking for new ways
to harness the power of flowing water:


It’s a brilliant day outside. Craig Collar is perched on a rocky outcropping
overlooking rushing green water swirling and eddying below. Collar says
the water is moving so quickly because this is one of only two spots where
the Pacific Ocean flows into Puget Sound:


“As the tide comes in, it comes into this constrained passageway at
Deception Pass. Y’know, all that energy gets channeled, focused
through this very narrow area. So that’s what results in these rapid
tidal currents that we’re seeing right here.”


Collar researches new power sources for Snohomish County Public Utility
District. His goal is to use a sort of underwater windmill to convert some of
this water’s energy to electricity and funnel it onto the power grid. It’s called
“tidal power.”


Collar says there are dozens of underwater turbine designs to choose
from. Some look like a standard wind turbine with three big blades; others
look like a metal donut or a fish tail.


The Utility District is considering putting underwater turbine farms at half a
dozen locations around Puget Sound. It estimates tidal energy could power
at least 60,000 homes. Collar says the technology has a lot going for
it. It doesn’t emit carbon dioxide or other pollutants. He says underwater
turbines can be much smaller than wind turbines because they’re so
efficient:


“And that’s just as a result of the higher density of water. Water’s
roughly 800 times denser than air, so it contains a lot more energy.”


Unlike the wind, tides aren’t really affected by the season. You know the
saying: “predictable as the tides.” Collar says lunar phases let you forecast
the tides for decades into the future:


“Where with wind, you’re doing good if you can forecast hours or
even a little bit ahead. That really helps utilities like us integrate that
power into the power grid.”


Collar acknowledges there are a lot of questions about the impact of tidal
turbines on marine ecology.


These questions worry nearby Native American tribes. The Tulalip
reservation is close to Deception Pass, and they fish throughout Puget
Sound. Darryl Williams is the tribes’ environmental liaison:


“Five species of salmon, orca, grey whales, eagles, hawks, falcons…
y’know, we have numerous species of fish and marine mammals and
migratory birds that use the areas that are being proposed for these
turbines, and the studies really haven’t been done yet to show what
the impacts may or may not be.”


Along with the marine environment, Williams says the tribes are worried
that tidal turbines could scare away fish or get tangled in fishing nets.


“For the tribes, the fisheries aren’t only an economic source but
they’re also part of the tribes’ culture. Most of our cultural activities
are centered around salmon, and if we can’t catch the salmon, then
that part of our culture really goes away.”


A research team at the University of Washington is looking for ways to
make tidal power work without harming sea life. Brian Polagye is a
mechanical engineering graduate student whose focus is renewable
energy. His team is working with the oceanography department to look at
the ecological risks of tidal power. But Polagye says there are a lot of
misconceptions about what those risks are.


“The most obvious one is the question of ‘Oh! So you’re going to put
these rotors in the water and you’re gonna make sushi in addition to
electrical power.’ People view these turbines kind of as almost a
propeller that’s moving through the water so rapidly that if anything
gets near it it’s gonna get chopped to pieces. In practice, you can’t
actually run the rotors that fast. The maximum speed that the tip of
the rotor can turn at is about 25 miles an hour. Which is actually
relatively slow.”


Polagye says one of the biggest risks is that removing some of the energy
from the tidal currents will change the ecology downstream. He’s studying
how much power can be extracted from an estuary before it has a
noticeable effect on the ecosystem.


Back at Deception Pass, Craig Collar with the utility district says even if
there is a small ecological impact, it’s key to look at the overall picture:


“At the end of the day the thing that’s compelling about tidal energy
for us is there just aren’t very many opportunities for clean,
renewable, emission-free energy that’s both predictable and close to
the loads. And all those things are true for tidal energy in the Puget
Sound region, and there simply is no other renewable for which all
those things are true.”


The utility is working with the University of Washington to figure out
whether tidal power is viable in Puget Sound. If so, it could help reinvent
hydropower on the Pacific Coast for the next generation.
