National Science Education Standard: G History and Nature of Science Grades 5 to 8
A green ocean
What color would you paint the oceans on our planet? Blue? Try green. At least that’s what a NASA satellite 450 miles above our heads is telling us to do.
Clearing a carbon catastrophe
We’re letting loose tons — literally — of carbon dioxide into our skies each day. And a good amount of that CO2 is finding its way into the ocean. Scientists from all over the world are rolling up their sleeves to try to avoid a global disaster.
Climate change is impacting even one of the most remote places on Earth: Antarctica. Krill numbers are down, salp numbers are way up, and the entire food web down there is in the balance.
Penguins in the hot seat
The temperature in Antarctica is rising, and Hugh Ducklow is watching an entire ecosystem change before his eyes. What happens if the ice just keeps on melting?
Of bonds and blooms
Sometimes the ocean can be a threat to human health. Barb and Gary Kirkpatrick, a wife and husband scientist team, describe what they’re doing to notify the Florida public about red tides and harmful algal blooms.
The glide of a lifetime: Part II
Scott Glenn and Oscar Schofield have a passion for creating the next generation of ocean explorers. In this episode, they’ll share their deep commitment to education and why they feel it’s going to help ocean science in the long run.
The glide of a lifetime: Part I
Oscar Schofield and Scott Glenn pilot underwater robots all over the world, sampling the ocean half a world away and saving lives in the process, but they never have to leave Rutgers University in New Jersey.
Huijie Xue forecasts the underwater weather of the Gulf of Maine: its temperature, its salinity, and its currents. And a lot of people are tuning in. [audio:http://coseenow.net/podcast/files/2009/04/og06.mp3]
Chris Martens is alarmed by the global disappearance of corals. To learn more, he lives at the bottom of the ocean on Conch Reef off Key Largo, Florida for up to 2 weeks at a time.
Seeing the small
Heidi Sosik and Rob Olson describe how a shared frustration led them to develop a special underwater camera that takes pictures of tiny cells in the ocean. It has revolutionized how the ecology of the ocean is studied. [audio:http://coseenow.net/podcast/files/2009/02/og02.mp3]
