Radio Program
Our regular Science and the SeaTM radio program presents marine science topics in an engaging two-minute story format. Our script writers gather ideas for the radio program from the University of Texas Marine Science Institute's researchers and from our very popular college class, Introduction to Oceanography, which we teach to hundreds of non-science majors at The University of Texas at Austin every year. Our radio programs are distributed at to commercial and public radio stations across the country.
If you live near the coast, few words are scarier than these: Category Five. That’s the classification for the most powerful hurricanes. The storms have maximum sustained winds of at least 157 miles per hour. And their potential damage is catastrophic. They can flatten houses, bring massive storm surges, and cause heavy rainfall well inland.
Scientists in Australia are trying to paint the sea floor red. They’re giving a helping hand to the red handfish—one of the most endangered fish on the planet.
The fish is only three or four inches long. It’s named for the fins on its sides, which are shaped like small hands. In fact, the fish uses those fins to walk along the ocean floor—it seldom swims. The hands can be pinkish brown, but they can also be bright red, along with the mouth and other body parts.
A massive hailstorm blasted northeastern Spain a couple of years ago. It lasted only 10 minutes or so. But it produced the largest hailstones ever recorded in the country—the size of softballs. It might have been kicked up a couple of notches by another type of “weather” event—a marine heatwave.
The storm roared to life on August 30th, 2022. It caused major damage to roofs, cars, and crops. It injured 67 people, and killed a toddler, who was hit in the head by one of the giant hailstones.
Many gardeners use clam shells as decorations. But not many garden the clams themselves. Yet clam gardens can yield more clams than untended shorelines, provide more species diversity, and even protect the clams from the acidity in today’s oceans.
Clams were gardened as early as 4,000 years ago by the people of the Pacific Northwest, from Alaska to Washington. In some regions, the gardens lined the entire coastline.
Life along the American coastline has been getting more perilous. Earth’s warming climate is causing a rise in sea level, an increase in major hurricanes, more marine heatwaves, and many other problems. That costs time, money, and lives. And things are expected to get even worse in the decades ahead.
Thresher sharks are some of the “snappiest” fish in the oceans. They have an oversized tail fin that looks like a scythe—and is almost as deadly. A shark “snaps” the fin like someone snapping a towel in a locker room, stunning its prey. And a recent study worked out some of the details on how the shark does it.
Threshers are found around the world. Most stay fairly close to shore, and not very deep. Adults can grow to about 20 feet long.
It may sound surprising, but many mountains are hiding from us—some of which may be more than a mile high. Scientists are finding more of them all the time, though—at the bottom of the sea. A research cruise in 2023, for example, found four of them in the Southern Ocean.
When you build a house, it affects the surrounding ecosystem. The same thing applies to houses built by fiddler crabs in salt marshes. Their burrows can help or hinder the surrounding plants, affect the flow of water, and perhaps cause the marsh to send more greenhouse gases into the air. Thanks to all of that, fiddlers are sometimes described as “ecoengineers.”
In 1875, Navy lieutenant commander Charles Dwight Sigsbee and his ship, the George S. Blake, began a journey into the history books. They started measuring the depth of the Gulf of Mexico with a mechanism that Sigsbee created. When the job was finished three years later, the ship had measured the entire Gulf—the first ocean basin to have an accurate map of all its contours.
Olive trees are sprouting all across the Balearic Islands—a chain off the Mediterranean coast of Spain. The largest island, Mallorca, has more than 800,000 cultivated trees. They yield a good portion of the world’s supply of extra virgin olive oil.
