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.

Earth's changing climate is expected to produce higher temperatures and stronger tropical storms. And when you put those two together, the results could be especially deadly.

A team of scientists recently studied the risks of extreme heat -- defined as a heat index of 105 degrees Fahrenheit or higher -- after the landfall of a hurricane or typhoon. The team found that such a one-two punch could pose major health risks for millions of people.

For more than three months, giant kelp off the coast of California bobbed up and down like a pumpjack in an oil field. The goal of that motion was to replace a few pumpjacks by developing a replacement for some of the country’s oil.

The Pacific coast of South America is a bit like a medieval castle surrounded by a moat. The “castle” is the Andes Mountains, which hug the coast. And the “moat” is the Peru-Chile Trench -- a gash in the ocean floor that’s miles deep.

Castle and moat were built by the motions of two of the plates that make up Earth’s crust. The Nazca Plate, which makes up part of the floor of the Pacific Ocean, is sliding under the South American Plate, which makes up most of the continent.

The Mediterranean Sea has been recording sea level for millions of years in a cave on a Spanish island. As the water rises and falls, it adds layers of minerals to rock formations inside the cave. And interpreting those layers may help scientists better understand what could happen to future sea level.

There are many symbols of love, from the heart to red roses. And for some couples in Japan, it’s a glass vase -- the skeleton of a sponge.

Venus’s flower basket is a type of glass sponge. Various species of glass sponge are found around the world, usually in fairly deep waters. The largest concentrations of them form reefs off the coast of British Columbia.

Today, the word “trade” means to swap something. That hasn’t always been the case, though. Centuries ago, it meant a path or a track. The new definition blew in on the wind -- the trade wind.

Trade winds blow in belts that flank the equator. The Sun heats the air and oceans at the equator. Warm, humid air then rises and heads toward the poles. As it reaches about 30 degrees north and south of the equator, the air cools and descends.

From November through April, a tiny marine creature is pretty common in the coastal waters of the northern Gulf of Mexico. It’s a species of copepod. It looks like a cross between a flea and a shrimp, but it’s only about a millimeter long.

When you walk on a tattered carpet or a stained-up rug, you don’t usually worry about it lunging up and biting you. Unless, that is, you happen to be walking through shallow coastal waters around Indonesia or parts of Australia. In those areas, the carpet just might give you a nasty shock.

Hanging out in the water while a hurricane is bearing down sounds a little scary. But that’s just what some underwater “gliders” are doing. They’re recording ocean conditions before, during, and after hurricanes pass overhead. That’s helping scientists improve their forecasts of hurricane intensity.

The squid has quite a nerve. In fact, it has the biggest nerve fiber in the animal kingdom -- a thousand times wider than the typical human fiber. That’s made the squid a good subject for learning about how nerves work -- and how they can misfire.

The massive squid nerve fiber is known as a giant axon. It forms a ring around the creature’s esophagus, and it’s protected by a hard cap. The axon is up to a millimeter wide.
