22-Storied careers: Ocean sensors and dog scenters
Tommy Dickey is an emeritus oceanographer from U.C. Santa Barbara and Naval Operations Chair in Ocean Sciences. His modeling and observational research yielded ocean monitoring technologies and tools. For retirement, Tommy trains and deploys Great Pyrenees as therapy dogs, while studying scent dogs’ capacity to detect COVID-19.

This episode is about how satellite technology is being used to study a big chunk of the earth’s surface. Seventy percent of the earth comprises water but we know very little about it. Color sensors aboard some satellites can actually reveal a lot about phytoplankton or microalgae blooms that are linked to ocean temperatures. These tiny organisms contribute to half the photosynthesis on the planet.

Science is all about experimentation, discover, and sharing those results. But what happens behind the scenes? What stories do scientists have to tell that don’t make it in the manuscript or the classroom lecture?

To the untrained eye, Arctic ice appears unchanging, but conditions can shift quickly, and often reveal life-threatening hazards when they do. It is an unforgiving environment, but the Inuit know how to navigate it. That knowledge has been passed down through generations, and a new app is giving centuries-old Inuit knowledge a very modern form.

Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.

Anant Pande is an Indian polar researcher who studies snow petrels – shy pelagic (sea-faring) birds who nest on rock crevices in Antarctica. These endemic birds prefer to nest near less icy waters. Climate change has melted polar oceans and perhaps made it less energy intensive — as they have to fly shorter distances to find non-frozen oceans.
Read More14-Ice: Glacier tourism on thin ice
Glaciers around the world are melting because of climate change. Yet, while glaciers might be smaller than they once were, that’s not stopping tourists from flocking to see them.

Cool off from the summer heat with our next six-part miniseries all about ice – from those who call it home to its use as a tool in science.

When you hear the word “extinction,” chances are you probably think of the extinction of the dinosaurs and a big rock. But did you know that there were other factors at play that lead to that extinction including volcanos and sea-level rise?
Read More6-True story: Migrating robins & thieving capuchins
Emily Williams has traveled the world in search of birds. As a biologist, she’s worked in Kansas, Argentina, Australia, and Denali, and studied loons, flycatchers, kingbirds, and more. And even with all these experiences and diverse species interactions, she’s now landed (ha, get it?!) on studying the common robin.
