Indian Ocean Air
Pollution (1/3/00)
Sooty particles called aerosols fill the air over the
Indian Ocean. An international effort called the "Indian
Ocean Experiment" measures how these aerosols may
counteract warming from greenhouse gases.
Listen
Alien Ocean (1/4/00)
On a clear night, with a pair of binoculars, you can see
the moons of Jupiter -- including Europa. Images received
from NASA space probes suggest that Europa's surface may
be covered with ice -- and below that ice may be ocean
Listen
Hardbottom
Dredging (1/5/00)
Adding sand to a beach that's been washed away by a
storm -- it's called "beach re-nourishment." But the
process that nourishes a beach may not be healthy for the
fishes that rely on "hardbottom" habitat near shore.
Listen
Seabird
By-catch (1/6/00)
The last thing that salmon fishermen in Washington state
want to catch in their gill nets is seabirds. But all too
often, diving birds get tangled and drown. Now scientists
have some tips that will help keep the birds out of the
nets
Listen
Seal Worms (1/7/00)
Ever since the Marine Mammal Protection Act was passed,
there are more seals around. But along with the seals,
there's more of something else: "sealworms," a kind of
parasite that also infects the fish you eat.
Listen
CO-2 Threat to
Coral (1/10/00)
Carbon dioxide from fossil fuels already affects corals
indirectly, by contributing to global warming. Now
there's new evidence that carbon dioxide gas also affects
corals directly -- it dissolves into seawater and stunts
their growth.
Listen
A Cult of
Swordfish (1/11/00)
The Chumash people once lived on California's Channel
Islands, near modern-day Santa Barbara. Artifacts from
archaeological digs reveal that the majestic swordfish
played a key role in the Chumash culture.
Listen
Ocean Sunfish (1/12/00)
Big and round, the ocean sunfish gets its scientific
name, "mola" from the Latin word for "millstone." It's
called "sunfish" for its habit of floating on the ocean's
surface, apparently basking in the sun.
Listen
Jellyfish and
Hypoxia (1/13/00)
Did you go to the beach last summer? Was your refreshing
dip spoiled by a swarm of stinging jellyfish? Think about
this: Scientists say that human actions may create the
conditions that allow jellyfish to thrive.
Listen
Salmon Sense (1/14/00)
Salmon hatch in streams and rivers, then swim far out to
sea. Years later they find their way back to their home
streams, navigating only by sense of smell. Now
scientists are discovering exactly how salmon learn to
follow their noses.
Listen
Mega-Teeth (1/17/00)
You can learn a lot from a tooth -- especially a fossil
tooth from the ancient jaw of the largest shark ever to
roam the seas. Today, the story of Megalodon, whose bite
makes the great white shark look like a great big
wimp.
Listen
What's in a
Name? (1/18/00)
The common mussel. As its name suggests, it's, well,
common. Scientists thought they knew all there was to
know about this bivalve. But only recently did we learn
that what we called a single species is actually
three.
Listen
African Dust and
Coral (1/19/00)
In the Caribbean, coral face one more problem: mats of
fast-growing algae that smother the reefs. What makes the
algae grow so fast? Wind-born dust from Africa may act
like a fertilizer.
Listen
Down the Drain (1/20/00)
Think of the ocean as a big bathtub, with water flowing
in from the taps -- and water running out drown the drain.
Scientists used to think that "water in" was equal to
"water out." Now they say the tub is going dry -- but
slowly
Listen
Antifreeze
Fish (1/21/00)
In cold weather your car needs antifreeze in the
radiator. Antarctic cod that swim in freezing water come
equipped with their own natural antifreeze -- thanks to a
mistake by Mother Nature.
Listen
Delayed
Reaction (1/24/00)
Some kinds of pollution kill fish outright -- spilled oil,
say, or acid waste. Today, the story of pollutants that
act more subtly. They mimic natural hormones. And the
fish don't feel their effects for months.
Listen
Seahorse
Husbandry (1/25/00)
Picture an animal the size of a salt shaker, with the
head of a horse . . . and the tail of a dragon. It's a
seahorse. Unfortunately, these enchanting creatures are
in trouble. But "Project Seahorse" is galloping to the
rescue.
Listen
Seahorse
Solutions (1/26/00)
Things sound grim for seahorses. They get ground up to
make medicine, or dried to make tacky souvenirs, or
captured for the aquarium trade. But it's not all bad
news. Today, learn what you can do to help.
Listen
Pfiesteria
Perspective (1/27/00)
Can you define "Pfiesteria?" If you can, you know more
than most people. This toxic algae kills fish. And
according to a recent survey, Pfiesteria may have a
deadly effect on the tourist industry as well.
Listen
Solitary
Killers (1/28/00)
It used to be, if you travelled on a ferry boat, you
resigned yourself to a slow trip. Today high speed
ferries have changed the pace of sea travel. But progress
has come at a price, in the form of "killer waves" or
solitons.
Listen
A Better View (1/31/00)
To learn about the Earth, you sometimes need to take a
big step back -- out into space. Scientists are using new
satellite technology to learn how humans affect the
ocean, by measuring ocean productivity and pollution from
space.
Listen
February 2000
3-in-1 Coral (2/1/00)
Boulder coral may grow in three shapes: round lumps,
columns, or flat plates. We used to think the coral's
shape was a function of how much sunlight reached it
through the water -- till one scientist made an accidental
discovery.
Listen
Death of a Pest (2/2/00)
Not long ago, a marine worm from South Africa showed up
in California. This worm attacked native snails, causing
hideous deformities. To vanquish the pest, one scientists
took tips from doctors who study human diseases.
Listen
Nauticisms -1 (2/3/00)
Did you know that many of the expressions used in
everyday speech have their origins in the sea? Clear the
decks and batten down the hatches -- we'll soon have you
talking like an old salt instead of a landlubber.
Listen
Unusual Dolphin
Deaths (2/4/00)
Bottlenose dolphins eat fish. Unfortunately, a dolphin
may get something extra with its meal -- a fish hook and
some line. Recreational fishing gear has been a factor in
several recent dolphin deaths.
Listen
Flavors of
Nitrogen (2/7/00)
Let's say you want to bake a cake. The amount of sugar
you add is important -- but so is the KIND of sugar: White
or brown. The same principles actually hold when you add
nitrogen to the ocean.
Listen
People and
Coasts (2/8/00)
Half the people in the United States live on the coast.
In fact, the number of people living in coastal areas is
on the rise around the world. With so many people heading
for the coast, that puts a stress on coastal
ecosystems.
Listen
Damselfish
Study (2/9/00)
What keeps fish populations from getting too big? Or look
at the question in another way: What keeps fish
populations from going extinct? There's new experimental
evidence that predators regulate fish population
sizes.
Listen
The Gully (2/10/00)
There's a place off the coast of Nova Scotia where the
floor of the ocean drops by as much as a mile -- where
whales and dolphins congregate. Here, scientists are
using new technology to gather information that was once
out of reach.
Listen
The Goldilocks
Dilemma (2/11/00)
You know the story of Goldilocks and the three bears: one
bed was too big, one was too small, and one was just
right? The same is true for ocean nutrients: You need not
too much, not too little, but just the right amount.
Listen
Reserve Protects
Fish (2/14/00)
There's a movement afoot to create a new "ecological
reserve" off the coast of Florida. Fishing will NOT be
allowed here. That sounds like bad news for fishermen,
but in fact, fishermen may benefit.
Listen
Rockfish Born
Alive (2/15/00)
An expert on rockfish describes their unusual
reproductive habits. Fertilization is internal, and the
embryos develop INSIDE the female fish -- a type of
development that's far more common in land-dwelling
mammals.
Listen
Global Ocean
Observing (2/16/00)
After a conference in 1992, the United Nations made a
recommendation of global proportions: Scientists should
set up a Global Observing Network. It would include
everything from ships and buoys to satellites.
Listen
Ecosystem
Foundations (2/17/00)
There's more to a play than what you see onstage. People
behind the scenes take care of the music, the sound, and
the lighting. It's the same in the ocean, where some of
the most important animals are not in the spotlight.
Listen
California Coastal
Warming (2/18/00)
The seabirds called sooty shearwaters live in the open
ocean. Once, you could find millions of them off the
coast of California. Today, populations are down 90
percent -- because of recent "sea-surface warming."
Listen
Oil Platform as
Preserve (2/21/00)
Some of the oil drilling platforms off the coast of
California have reached the end of their economic
lifespan. Should they be removed? If fish could vote,
they'd cast ballots to keep those platforms in place.
Listen
Black Coral
Harvest (2/22/00)
At a tropical shop, you're tempted to buy a stunning
necklace made of glossy black coral. Before you buy, know
the facts behind the fashion: All 150 species of black
coral have been listed as "commercially threatened."
Listen
Species
Mapping (2/23/00)
Roads are red, and oceans are blue . . . ." You can find
these color-coded cues on any road map. On today's show,
you'll meet a scientist who makes unique maps of the
ocean as well as the animals that live in it.
Listen
SEA-WIFS
Technology (2/24/00)
One way you can study the ocean is to dive right in. But
you can also study the ocean from space. That's what the
satellite called SEA-WIFS does. The information it
gathers paints a very colorful picture
Listen
Nauticisms - 2 (2/25/00)
The English language has a rich marine heritage -- many of
the expressions that sailors used long ago are still in
use today. On today's show, we'll try not to go overboard
as we show you the ropes.
Listen
Wild Ocean (2/28/00)
You've probably visited some of America's spectacular
national parks. Today, a review of a new book by ocean
scientist Dr. Sylvia Earle that celebrates the beauty of
another classic American landscape -- the one underneath
the sea.
Listen
9 An Ocean in
Colorado (2/29/00)
The city of Denver, Colorado, is high in the Rocky
Mountains. But it's built on rocks that were once the
floor of an ancient sea. Last summer, the ocean returned
to Denver -- in the form of a major new aquarium.
Listen
March 2000
Real Navy Seals (3/1/00)
Maybe you've heard of the "Navy Seals" -- an elite corps of
highly trained underwater demolition experts. But did you
know that in addition to training two-legged Seals, the
U.S. Navy ALSO trains sea lions and dolphins?
Listen
Sea Lion 911 (3/2/00)
The U.S. Navy trains sea lions to help retrieve equipment
underwater. But occasionally, these expert divers have
other assignments. One time, a Navy sea lion actually
helped to solve a murder!
Listen
Heyerdahl Prize (3/3/00)
The Norwegian Shipowners' Association has established a
new environmental award. It's named for Dr. Thor
Heyerdahl, Norway's most famous ocean explorer, a man who
has helped raise awareness of ocean pollution.
Listen
Making Waves (3/6/00)
One listener wants to know, "How are waves generated?"
The wind blowing over the water is what makes most waves,
but sometimes underwater earthquakes or volcanoes can
trigger a massive "tidal wave" or tsunami.
Listen
Marine Mammal
Center (3/7/00)
In the spring of 1998, beach-goers in Monterey,
California, watched in horror as California sea lions
suffered violent seizures. Tracking down the cause of the
sickness took a whole team of ocean detectives.
Listen
Surf Perch (3/8/00)
The small, colorful fish known as "surf perch" have an
unusual style of reproduction -- one that's usually
reserved for mammals. The young fish grow inside their
mother, absorbing nutrients from her body fluids.
Listen
Trashing
Turtles (3/9/00)
Endangered loggerhead turtles routinely eat bits of
floating plastic. The trouble is, the stuff adds bulk to
their diet, but not nutrients. One study showed young
turtles may not get enough calories to grow normally.
Listen
Ocean Asteroid
Evidence (3/10/00)
It's an ancient question: Why did the dinosaurs die, 65
million years ago? Scientists say the evidence points to
an asteroid that smashed into the Earth. New
evidence from the bottom of the ocean supports this
idea.
Listen
Swimming with
Sharks (3/13/00)
When dozens of leopard sharks gathered off La Jolla,
California, last October, some people waded right in to
swim with them. Why did the sharks gather so near the
shore? It's still a mystery to scientists.
Listen
Warm Wetsuit (3/14/00)
Ice-cold water on your skin . . . it can chill you to the
bone. Most scuba divers stay warm by wearing either
"wetsuits" or "dry suits." Now there's some hot news from
the U.S. Navy about a scuba suit that makes its own
heat
Listen
Contaminated
Sediments (3/15/00)
Massive container ships need deep-water ports to anchor
in. No wonder dredging is a common practice. The trouble
is, dredging can release toxic contaminants that were
stored in the bottom sediments.
Listen
Rehab Pros and
Cons (3/16/00)
The Marine Mammal Center in Sausalito, California, is
America's largest marine mammal rehabilitation center.
Today, a look at what we learn from seals and sea lions
when we lend a helping hand.
Listen
Tar on the
Beach (3/17/00)
Sticky tar on the beach in Santa Barbara -- must be an oil
spill, right? Actually, the oil could also come from a
natural seep. The Native Americans who once lived here
used the sticky stuff as a kind of all-purpose
adhesive.
Listen
Moon and Tides -
1 (3/20/00)
A listener asks: How does the moon affect the tides? The
moon's gravity pulls on the ocean and makes it bulge.
Meanwhile, underneath the ocean, the Earth is spinning.
When you move through the bulge, that's high tide.
Listen
Moon and Tides -
2 (3/21/00)
Yesterday was the first day of spring. The moon was full.
And in coastal areas, a "spring high tide" washed up on
shore. But that name is a little misleading. You actually
get "spring high tides" in EVERY month of the year.
Listen
Moon and Tides -
3 (3/22/00)
The moon cycles through its phases in about 29 days. This
lunar cycle affects the daily tides. But there are OTHER
lunar cycles that can affect the tides, and one of them
takes almost two decades to complete.
Listen
Louisiana Sea
Level (3/23/00)
In coastal Louisiana, wetlands are disappearing faster
than a pot of jambalaya at a Mardi Gras feast. Since 1930
the state has lost an expanse of low-lying wetlands
larger than the entire state of Rhode Island.
Listen
Recycled Fishing
Line (3/24/00)
The Berkley company is a world leader in the
manufacturing of fishing line -- and also in its recycling.
The company turns 10 million miles of fishing line a year
into "Fish Habs" -- artificial habitat that attracts and
shelters fish.
Listen
Manatee
Hearing (3/27/00)
You see signs on Florida waterways that say: "Go slow,
manatees." The speed limits are to prevent boats from
colliding with these slow-swimming marine mammals. But
new research shows boats may be unsafe at ANY speed.
Listen
Mercury
Munchers (3/28/00)
One waste product of some manufacturing processes is
mercury. This heavy metal is extremely toxic. Today,
you'll hear about an innovative way to clean up
contaminated water -- with bacteria that munch on
mercury.
Listen
Beached Bird
Survey (3/29/00)
Some people go beach-combing for driftwood or seashells.
Today's show is about a project in Washington State where
enthusiastic volunteers comb the beaches for something
quite different: Dead birds.
Listen
Sharks Don't
Hibernate (3/30/00)
During the summer, you often spot basking sharks in the
English Channel, lazing at the water's surface. But in
the winter these big sharks disappear. Do they hibernate,
as scientists once thought? New research says, "no."
Listen
April Fool's
Fish (3/31/00)
Tomorrow is April first -- April Fool's Day. But we're not
fooling when we tell you there's a fish called the
"sarcastic fringehead." And we're STILL not making this
up when we say the fish makes a home inside old beer
bottles.
Listen
April 2000
Methane Hydrate (4/3/00)
It looks just like ice . . . yet you can burn it as fuel.
What is it? Methane hydrate. This frozen gas, found in
deep-ocean sediments, is the focus of new research
efforts. It holds promise as an energy source -- but also
some risks.
Listen
Energy from
Algae (4/4/00)
Most of the energy you use is generated by the burning of
fossil fuels such as coal or gas. That generates
greenhouse gases. Today's show is about a promising new
source of energy that releases NO greenhouse gases:
Algae.
Listen
Ocean Diseases (4/5/00)
In recent decades, scientists have documented what seems
to be a significant increase in the number of disease
epidemics that affect ocean life. Are ocean epidemics
REALLY on the rise? Today's show explores the
evidence.
Listen
Mapping Corals (4/6/00)
Back in 1998 the United States established a Coral Reef
Task Force. This group is working to map and monitor
every coral reef in the United States, using everything
from ships and divers to satellites.
Listen
"Ground Truth" (4/7/00)
Satellites circle the globe every day, collecting images
of Earth's surface. To make sense of these images, you
need something called "ground truth," where you measure
what's happening down on the ground . . . or, in the
ocean.
Listen
New Sea Squirt (4/10/00)
They seem like lowly life forms -- simple blobs that stick
to rocks and piers. Yet of all the sea creatures without
backbones, sea squirts are OUR closest relatives. No
wonder scientists are excited about the discovery of a
new species.
Listen
Hudson's Bay
Bears (4/11/00)
In winter the sea ice creeps across Canada's Hudson Bay,
and the polar bears follow. The ice is a platform from
which the bears hunt for their favorite food -- seals. But
now, the hunting grounds seem to be melting down.
Listen
Fertilize the
Ocean (4/12/00)
The idea sounds simple: Drizzle fertilizer into a patch
of open ocean, and the almost-barren water will bloom
with phytoplankton that take up carbon dioxide -- relieving
global warming. Can this grand idea really work?
Listen
Argo Program (4/13/00)
A Greek myth tells of a here named Jason who sailed the
ocean in a ship called the Argo, on a quest for the golden
fleece. Today, the story of a modern-day Jason and Argo.
Their quest? Find a better way to predict Earth's
climate.
Listen
Basking Shark
Protection (4/14/00)
When an animal is 30 feet long, with a mouth the size of
a manhole cover, you'd have to say it's hard to miss. Yet
basking sharks have been almost ignored by regulatory
agencies. Now they're finally in the spotlight.
Listen
Atlantis of the
Iguanas (4/17/00)
The Greek philosopher Plato told stories of Atlantis -- a
chain of lovely islands that sank to the bottom of the
ocean. Today, the story of a lost-and-found island chain
that scientists are calling, "The Atlantis of the
Iguanas."
Listen
Coral Flypaper (4/18/00)
You've heard of flypaper -- it's the sticky stuff you hang
from the ceiling to kill flies. Well, now there's a new
invention called "coral flypaper." You hang THIS stuff
over a coral reef. And it's not a killer, it's a
conservation tool.
Listen
Dolphin Gangs (4/19/00)
Researchers who study the bottlenose dolphins of Shark
Bay, Australia, say the males team up in small groups
that can only be described as "gangs." What's more, two
gangs may work together to defeat a rival.
Listen
Veined Rapa
Whelk (4/20/00)
A predatory snail from the Sea of Japan has somehow made
its way to the Chesapeake Bay -- perhaps carried in the
ballast tanks of freighters. Now the veined rapa whelk is
munching its way through the native clams.
Listen
Earth Day (4/21/00)
Tomorrow is "Earth Day." But this planet is more than
two-thirds water, so around here, we call that holiday
"Ocean Day." But don't limit your celebrations: We've got
five tips for you on how to make EVERY day Ocean Day.
Listen
GO-MOOS (4/24/00)
Since the moose is the state animal of Maine, you might
assume that "GO-MOOS" is a Univerity of Maine football
cheer. In fact, it's the Gulf of Maine Ocean Observing
System -- and scientists are the ones cheering this new
observatory.
Listen
Under Pressure (4/25/00)
The compound called T-M-A-O is nothing if not versatile.
It's what gives seafood a fishy smell. It keeps marine
animals from loosing water. And it helps creatures to
survive the enormous pressure of the deep ocean.
Listen
Deep-water
Corals (4/26/00)
Deep-water corals are more common than scientists once
thought. And like their shallow water cousins, deep-ocean
corals create habitat for other life forms. But deep
reefs are threatened by fishing and oil drilling.
Listen
Fishing Down the Food
Chain (4/27/00)
Cod in the Gulf of Maine have been fished out. So their
prey -- lobsters -- are now more plentiful . . . AND more
important to the fishing industry. This phenomenon is
called "fishing down the food chain."
Listen
Sea Urchin
Story (4/28/00)
Once more than 1,500 fisherman made a living selling
Maine sea urchins to Japan. Today the urchins are almost
gone -- and the kelp they used to graze on is growing like
crazy. Can the urchins make a comeback?
Listen
May 2000
Hawaiian
Reserves (5/1/00)
Not long ago, nine marine reserves were established on
Hawaii's Kona Coast. You can imagine that the people who
collect reef fish here for the aquarium trade might
object . . . except the collectors had a hand in the
plan.
Listen
Red Tide
Hotline (5/2/00)
If you live near the coast, you know that one of life's
simple pleasures is colelcting your own clams or mussels
for a seafood dinner. But before you grab your rubber
boots and a bucket, remember to check the red-tide
hotline.
Listen
History of Cod
Fishing (5/3/00)
Today's show brings you a brief history of cod fishing in
New England. Things have changed since the 1600s, when
the big fish were so numerous they "vexed" the ships of
European explorers.
Listen
Salmon in the
Trees (5/4/00)
You probably know that salmon migrate. They hatch in
fresh-water streams, grow up in the ocean, then swim back
upstream to breed. But did you know salmon keep moving
after they're dead? And that they end up in trees?
Listen
Better Beach
Testing (5/5/00)
It's the time of year when you plan your summer vacation.
And Chances are, your plans include a trip to the beach.
But is it safe to go in the water? A new program launched
by the US EPA aims to help prevent pollution.
Listen
Structural Marsh
Management (5/8/00)
The state of Louisian loses an area of wetland the size
of a football field each day. You can see why managing
coastal marshes is a priority in the state. But one
common managment practice may be counterproductive.
Listen
Dolphin Captive
Breeding (5/9/00)
In the United States, many aquariums now have bottlenose
dolphins on exhibit. Behind the scenes, these aquariums
are collaborating to conduct captive breeding programs
-- with striking success.
Listen
When Whales
Fly (5/10/00)
You know what it's like to make travel arrangements for
yourself. So just imagine if you had to book a flight for
a whale! Today you'll hear from an expert at the Shedd
Aquarium about what it takes to make whales fly.
Listen
Drowning in the South
Pacific (5/11/00)
A few months ago, the South Pacific state of Kiribati
enjoyed global fame as the first place on Earth to greet
the new millennium. But residents here fear their island
nation may not survive to the end of the 21st
century.
Listen
Contaminated
Sediments (5/12/00)
Most US seaports have to be dredged occasionally. The
trouble is, ten precent of the sediments dredged each year
are badly contaminated. Today, a case history of
contamination: New Bedford Harbor.
Listen
Glow with the
Flow (5/15/00)
When they're disturbed -- say, by the flash of a fish tail
or the bow wave of a boat, the microscopic algae called
dinoflagellates bioluminesce -- that is to say, they light
up. Can designers use this property to learn to build
better boats?
Listen
The History of
Diving (5/16/00)
Today, high-tech equipment makes scuba diving safe and
comfortable -- but it wasn't always so. The history of
humans breathing underwater ranges from from hollow reeds
in ancient Persia to modern regulators.
Listen
Timing Your
Swim (5/17/00)
You're on vacation, and ready for a refreshing morning
dip. Before you grab your towel and head for the bech,
consider this: New research suggests the water may be
cleaner if you wait till the afternoon.
Listen
Phragmites
Expansion (5/18/00)
Grass doesn't always grow in a velvety lawn. One kind of
grass grows 15 feet tall. It's called Phragmites, and
from a conservationist's perspective, this grass can be
one of the good guys -- or one of the bad guys.
Listen
9 Reserve
Experiment (5/19/00)
After lengthy review, Hawaii has signed into law "Rule
306." One outcome has been the creation of nine new
marine reserves along the Kona Coast. The fascinating
thing is, the borders of these reserves are not
fixed.
Listen
Trojan Gene (5/22/00)
Some fish farms are experimenting with genetically
engineered salmon. These fish grow big very fast. But one
scientist calls their extra gene a "Trojan gene." Like
the famous Trojan horse, it hides something
dangerous.
Listen
Incredible Mr.
Limpet (5/23/00)
Do you remember that old movie? It was a funny choice for
a name, because the character named "Mr. Limpet" was
actually a fish. On today's show you'll hear about
limpets -- and why they really are incredible.
Listen
Do Fish Sleep? (5/24/00)
Now, there's a question that could keep you up at night.
But don't worry, on today's show we'll lay the issue to
rest as we look at how an animal that has no eyelids
manages to catch some shut-eye.
Listen
No Minor Spills (5/25/00)
Dr. William Sydeman, the director of marine science at
the Point Reyes Bird Observatory has studied how oil
spills affect seabirds along the California coast. His
conclusion: "There's no such thing as a minor oil
spill."
Listen
New Microbe Detector (5/26/00)
When you go for a swim, or when you drink a glass of
water, you assume that water is safe . . . and usually,
it is. But standard tests to detect diseases do have
limits. That's why scientists are developing a new way to
test water.
Listen
Effects of Beach Grooming (5/29/00)
In southern California a full 80 percent of the coastline
is sandy beach. And many of these beaches are raked or
groomed regularly. That's nice for sunbathers -- but it's
devastating to other beach dwellers.
Listen
Small Stingers (5/30/00)
If you go for a swim off the coast of Queensland
Australia, you might worry about the great white sharks
that often cruise these waters. But your biggest danger
is probably a creature the size of your thumbnail: A
toxic jellyfish.
Listen
Cut Off in Their Prime (5/31/00)
In Southern Portugal, one popular snack is a beer and a
dish of crab claws. So, as you might expect, the local
fiddler crab populations are declining. Yet it's NOT
because fishermen are killing too many.
Listen
June 2000
Mussel Welcome
Mat (6/1/00)
Today, the story of a mussel that weaves mats on the
ocean floor. These mats actually CREATE habitat for other
forms of ocean life -- and that sounds like a good thing.
But the full story is a bit tangled.
Listen

Reserves (6/2/00)
The Commonwealth of the Bahamas has taken an important
step to protect its gorgeous coral reefs. Five new marine
reserves are on the drafting board. They're the first
step in an ambitious program of protection.
Listen
Whale Shark (6/5/00)
As their name suggests, great white sharks are big -- up to
20 feet long. Did you know there's a shark that's TWICE
as big, with thousands of teeth? It's called a whale
shark -- and people actually WANT to swim with it.
Listen
Gasping in the Chesapeake -
1 (6/6/00)
In summer, excess nutrients make algae grow in Chesapeake
Bay. When these algae sink to the bottom and decay, they
use up oxygen. That can create problems for fish -- but not
always in the way you might expect
Listen
Gasping in the Chesapeake -
2 (6/7/00)
Tiny fish larvae tolerate low oxygen conditions at the
bottom of the Chesapeake, while predators, such as
striped bass, head for the surface. But the coast is not
clear for fish larvae. Hungry jellyfish still hang
around.
Listen
Plankton Wars (6/8/00)
Last fall the Ukrainian security service accused four
scientists of exporting state secrets. Why? They were
merely studying ocean plankton. But you can detect
submarines by the trails they leave through
bioluminescent plankton.
Listen
Aquarius (6/9/00)
Next week, a team of scientists will unpack their gear at
a unique field station: It's underwater! The facility is
called Aquarius, and it's off the coast of Florida. We'll
tell you how you can chat with scientists 60 feet below
the surface.
Listen
Oil and Coral Don't
Mix (6/12/00)
In the North Sea, certain oil-drilling rigs will sone be
removed, a step that some environmentalists applaud. But
there's an ironic twist to the story: These structures
are encrusted with a protected species of coral.
Listen
Crab Parasite (6/13/00)
There's no such thing as a vampire, but the parasite
called Hematodinium sounds even creepier: It gets INSIDE
its victims and consumes their blood. The victims are
crabs, no people -- but people are still worried.
Listen
Acoustic Eye (6/14/00)
Imagine you're a diver, working in muddy, turbid water.
You can barely see your hand in front of your face. An
ordinary camera is useless here. Luckily there's a new
acoustic camera that sees right through the murk -- using
sound.
Listen
A Delicate
Problem (6/15/00)
What do you do when you're out on a boat, you're hours
from shore, and the boat has no "head," or bathroom? The
situation may be even more urgent than you think. Most
cases of shellfish contamination are caused this way.
Listen
Oyster Test (6/16/00)
On the coast, oyster beds are monitored to detect
contamination by bacteria. But these tests do NOT detect
certain harmful viruses. A new test may someday reduce
the risk when you eat raw oysters.

What Is Coral? (7/17/00)
A coral reef can look like an underwater city with towers
made of stone... or a beautiful garden full of colorful
flowers. Time for Twenty Questions: is coral animal, vegetable or mineral?
Listen
Combatting Copapods (7/18/00)
When isects attack a farmer's crops, he may spray an insecticde.
Fish farmers also use insecticides to kill fish parasites called
sea lice. Trouble is, insecticides kill more than the pests they target.
Listen
Fatty Food For Polar Bears (7/19/00)
You've heard what doctors recommend: you should eat a diet that's low
in fat. The prescription is quite different for one ocean animal.
Its good health DEPENDS on heaping servings of high-fat foods.
Listen
Viruses And The Ocean (7/20/00)
When I say "virus" you probably think of something harmful: a

Today, you'll hear how viruses actually play an essential role -- in
the ocean.
Listen
White Abalone (7/21/00)
On the ocean floor off the coast of California you'll find the white abalone:
a large snail with a large following -- among gourmets, that is. So
many people have proclaimed it delicious that the white abalone is
on the edge of extinction.
Listen
Nets That Let Fish Go (7/24/00)
Fishing the open seas with giant nets is not an exact science.
Despite regulations on mesh size, trawls catch almost everything
in their path. Now, new designs for fishing nets let small
fish escape.
Listen
Lampreys (7/25/00)
If Dracula kept an aquarium, he might stock it with the primitive
fish called sea lampreys. They look like eels, but they act
like vampires. Native to the Atlantic Ocean, these fish now
thrive in the fresh water of the Great Lakes.
Listen
Lamprey Eradication (7/26/00)
The best-laid plans of men and women can make nature go awry.
For example, locks and canals let sea lampreys into the Great
Lakes, along with the shipping trade. Getting rid of the lampreys
is another job entirely.
Listen
Seasickness (7/27/00)
The waves rock the boat... up... and down... and up... and down...

Your friends tell you to "look at the horizon." Why would that help?
Listen
SWATH Ship (7/28/00)
It's bad enough to get seasick when you're on vacation. What if
your work takes you out on the waves? Some ocean scientists
use sensitive equipment on rocking boats. That's why the
smooth-riding vessel called the "SWATH ship" was developed.
Listen
Arctic Pollution (7/31/00)
Mother's milk. What could be better for baby? But for
native people in the Arctic, there's a problem. Pollutants
carried on by wind and currents reach the Arctic Ocean
and move up the food chain.
Listen
Bryozoan Beach (8/1/00)
You've heard the saying "small things matter." That's true in
Florida, where scientists worked to protect a creature that
lives on grains of sand. Today, the "David and Goliath" story of bryozoans
and the beach.
Listen
Voyage Of The Beagle (8/2/00)
When the naturalist Charles Darwin traveled around the world

a fantasy. But you CAN make a short trip. Come along on a
submarine safari.
Listen
Seabird Spotlight (8/4/00)
What's in a name? More than one meaning, when you're talking
about the tiny seabirds called storm petrels. Let's take a look
at where the name "petrel" comes from -- and why these birds
are also called "Mother Carey's Chickens."
Listen
Eelgrass Limpet (8/7/00)
Let's ask a classic philosophical question with an ocean twist.
When a snail goes extinct in the seagrass, does anybody notice?
The answer is "no." The next question is "Why not?"
Listen
Secret Life Of The Oarfish (8/8/00)
Wherever sailors gather, you'll hear stories of sea monsters:
long, snakelike creatures that swim in sinuous loops. These ancient
tales of sea serpents may have their origin in real sightings
of one of the world's rarest fish.
Listen
Secret Life Of The Oarfish (8/9/00)
You've heard the saying, "There's a limit to everything." This
saying may be generally true. But when it comes to the ocean floor,
traditional wisdom has been turned topsy-turvy.
Listen
Stromatolites (8/10/00)
Scientists call them stromatolites. You find them in shallow,
salty water. They're dark and lumpy, like oversized heads of
broccoli. Are they alive -- or are they simply caught
between a rock and a hard place?
