Colorado & Oceans // Nitrogen & Snails

Feature #1 (time mark 5:30)  When people think of Colorado, they usually don’t think about “oceans”.  After all, Colorado doesn’t have much of a coastline these days, though it was definitely had oceanfront property a few hundred million years ago.   However, being in a landlocked state doesn’t mean that there isn’t any thing we … Continue reading “Colorado & Oceans // Nitrogen & Snails”

Ocean Acidification // Citizen Science

      Feature #1: Many problems plague the oceans and the fish and other species that inhabit them: overfishing, pollution, and much more. But perhaps the greatest threat to sea life – and possibly to humans – is ocean acidification.  That’s when the chemistry of the ocean changes and causes seawater to become more … Continue reading “Ocean Acidification // Citizen Science”

Ocean thermal energy//Climate and drought in the Rockies

Our live guests are consultant Dr. Robert Cohen and CU scientist Kristen Averyt.  Dr. Cohen discusses ocean thermal energy — a method to harvest some of the almost limitless solar energy captured daily by the oceans.  Dr. Averyt surveys the future of the Intermountain West as we increase temperature and put increasing population pressure on … Continue reading “Ocean thermal energy//Climate and drought in the Rockies”

STEM Research // Sex in the Sea

Today’s show offers two features: High School STEM Stars (start time: 5:00): Developing polymers to reduce waste from biodiesel production. Using 3D printing to design ocean textures, such as fish gills and waves, that blind students can use in textbooks to better understand nature. These are the kind of vexing challenges of seasoned scientists. Well, a select group … Continue reading “STEM Research // Sex in the Sea”
