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.

Bad weather can make it hard to navigate. It’s hard to see where you’re going if there’s fog or heavy rain, so you can find yourself off course and in trouble.

For a while, biologists have suspected that bad weather can make it hard for whales and dolphins to navigate, too -- not fog and rain, but space weather. Space weather is caused by magnetic storms on the Sun. Giant eruptions can spray Earth with energy and charged particles. That can disrupt satellites, interfere with radio communications, and knock out power grids.

Pass the salsa and the bean dip, please! It’s time to try the latest chips. They’re crunchy and healthy. There’s just one little catch: They’re made from jellyfish.

Few people in the west clamor for jellyfish. The slimy texture just isn’t very popular. And many people know that jellyfish tentacles can contain some nasty venom, which hardly helps its reputation.

In Asia, though, jellyfish are a delicacy. Their bodies, known as bells, are brined for several weeks in a combination of salt and alum. That dries the jellyfish out, giving them the texture of a pickle.

Plastic junk floats atop all the world’s oceans -- cups, bottles, wrappers, bags, and a thousand other products. These bits of trash can be found just about anywhere, drifting with the currents. And sometimes, they travel in clumps -- perhaps pulled in by small whirlpools.

One of the sleekest-looking dolphins is also one of the most elusive. It inhabits far-southern waters, where there are few people around to enjoy its beauty. Because of that, it faces fewer threats from fishing fleets and other hazards.

The hourglass dolphin is named for its unique coloring. Its body is black with a pair of white stripes down its sides. The pattern creates the look of an hourglass.

For some, “getting away from it all” might mean a trip to the South Pacific -- some delightful tropical island far from the cares of everyday life. But really getting away from it all means going to a point in the South Pacific where there are no islands within almost 1700 miles. It’s the point on the globe that’s farthest from any land, known as Point Nemo.

A type of fish found off the southeastern coast of Australia isn’t much of a swimmer. Instead, it prefers to crawl along the ocean floor on fins that look a lot like hands. But its walking may be limited. It’s critically endangered, with populations dwindling in a hurry.

There are 14 species of handfish, although one of those hasn’t been seen in more than a decade. They live in rocky, sandy regions, generally at depths of a few dozen feet. They’re found mainly around the island of Tasmania.

People try to predict all kinds of things, from the weather to football scores -- all with mixed results. Predictions of one phenomenon are usually pretty accurate: the tides. But getting it right requires good information about many factors.

In January of 2013, at an auction in Tokyo, a sushi-restaurant owner paid one-and-three-quarter million dollars for a Pacific bluefin tuna. Not a boatload of them, mind you, but a single fish.

The high price was mainly a publicity stunt. Yet even an average bluefin typically sells for tens of thousands of dollars. That makes it one of the most expensive fish on the planet. And that’s making it increasingly endangered.

In July of 1969, a small submarine and its six-man crew got stuck. They didn’t run aground, though. Instead, they were caught in a swirling eddy in the Gulf Stream, the current of warm water that flows along the East Coast. The sub needed to surface so it could be towed back into the flow of the Gulf Stream.

Later, scientists discovered what caused the eddy: an underwater mound known as the Charleston Bump. It’s about a hundred miles off the coast of Charleston, South Carolina, on the edge of the continental shelf.

Seagrass beds provide a home for many species of fish. The fish can hide from predators in the blades of grass, and find food in the sand and mud on the bottom. But when the beds get thinner and patchier, the fish thin out, too -- there are fewer fish, and fewer species of fish. So it’s important to keep seagrass beds intact -- splitting them up is bad for the entire ecosystem.
