6.5-Extinctions: Dinosaurs, volcanoes, the space station, oh my!
Join us for our next six-part miniseries on Extinctions as we learn about the demise of the dinosaurs, what makes a comet “extinct,” the Cambrian and Triassic periods, volcanoes, and the aforementioned (planned) fiery end of the International Space Station!

4-True story: Using TikTok for (shark) science good
Jaida Elcock says she thrives in chaos. And we’re inclined to believe her. From her ridiculously entertaining TikToks on animal facts, to her work with the non-profit Minorities in Shark Sciences (oh, did we mention she’s currently pursuing her Ph.D.), she seems to be managing that chaos pretty well. We talked with her about all of her endeavors, her inspiration from conservationist Jeff Corwin, and what (or who) she would like to see in science.

1-True story: Slapped by a (misinformation) shark
David Shiffman is a shark guy. It’s in his Twitter handle, he’s writing a book about it, and he was wearing a shark shirt the day we interviewed him. But more broadly he’s a marine conservation biologist, meaning he studies all sorts of ocean-going animals.

True (science) stories you’ve never heard before
Third Pod from the Sun is back, and we’re going weekly! Join us as we combat misconceptions about sharks, learn how to lasso lizards, hear from a Martian here on Earth, spark science joy via Tiktok, journey to Antarctica, and fight over food with some capuchins!

Staff Picks: Chasing Narwhals
University of Washington biologist Kristin Laidre travels to the Arctic to study animals many of us have only seen in pictures. She has successfully tracked down the elusive narwhal and been up close and personal with a polar bear seeking to understand how the loss of sea ice and the effects of climate change are altering Arctic ecosystems.

Scientists Mine 16th Century Ship Logs for Geophysical Research
As ships explored the world from the Age of Sail through 20th century, mariners kept detailed navigation records using the Sun and stars. Scientists scoured these ship logs, many of which are preserved in European libraries, for clues about Earth’s magnetic field. The work, published in 2000, created the first-ever magnetic field map for the past 4 centuries.

AGU’s 2021 Policy Priorities
As a scientific society whose members’ research and interests span the universe, AGU’s science policy interests are just as vast – from scientific integrity to funding for science to building resilience to natural hazards. In 2019, AGU began developing annual policy priorities to help focus our advocacy work and speed the advancement of important science policy and legislation. For example, last Congress by focusing on our policy priorities AGU was able to secure passage of the Space Weather Research …

Special Release: Mythical Monsters and their Real-life Inspirations (Part 2)
In this episode, the second in a two-part series, we chatted with Rodrigo Salvador, Curator of Invertebrates at the Museum of New Zealand, about the connections between giant squids and the Kraken, and Danielle J. Serratos, Director/Curator of the Fundy Geological Museum, about the links between prehistoric aquatic reptiles and the Loch Ness monster, respectively.

Special Release: Mythical Monsters and their Real-life Inspirations (Part 1)
We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must be a reason why such legends were created in the first place. In most cases, the legend in grounded in fact.

Third Pod Presents: Sci & Tell – Bärbel Hönisch, “Queen of Boron”
Bärbel Hönisch, Associate Professor of Environmental Sciences at Columbia University also known as Queen of Boron, transported us millions of years beyond the ice cores to the realm when Greenland had no ice.

Special Release: Deviations from the Norm
One of the most alluring parts of Earth and space science is that much of the key research takes place in the field, in some of the most incredible – and inhospitable – environments on the planet: on treacherous polar ice sheets, aboard sea tossed ships, at the mouths of active volcanoes, beneath turbid ocean waters, and atop the highest windswept peaks. Under these often less than ideal conditions, instruments …

E19 – Eavesdropping on the Ocean
To those of us on land, the world underneath the oceans seems quiet and serene. But scientists who study ocean acoustics will tell you it is anything but tranquil underwater. Our oceans are home to a cacophony of sounds – from the songs of marine mammals to the cracking of icebergs to the rumbling of earthquakes to the roar of ships.

A dedicated, university-based team that bridges the science-policy divide
Dr. Michelle McCrackin is a biogeochemist interested in how agriculture, urbanization, energy production, and land use change have influenced nutrient cycling in watersheds, with particular interest in lake and coastal ecosystems. She is a researcher with Baltic Eye in Stockholm, Sweden. For the past five years, I have been part of a novel team, called Baltic Eye, at Stockholm University’s Baltic Sea Centre. Our team is composed of researchers, …

The Ocean: A Sink for Carbon, Heat, and Now… Wealth
Dr. David Trossman earned a BA in mathematics and a BA/MA in physics from Washington University in St. Louis, a MA in public policy from the University of Chicago, and a PhD in physical oceanography from the University of Washington-Seattle before moving on to do postdocs, work at NASA, and land at the Institute for Computational Engineering and Sciences at the University of Texas-Austin, where he currently works as a …

E17 – Science Turns to Search and Rescue
The Arctic Ocean is topped with a layer of frozen sea water – sea ice – that grows every winter and shrinks every summer. To study the ice in detail, researchers hop aboard an icebreaker ship that can plow through the sharp, cold ice floes without being damaged.

E16 – Gunslingers of the Sea
Snapping shrimp are small but mighty creatures: they’re only a few inches long but are among the noisiest animals in the ocean. The loud cracking noise they make when snapping their claws sounds almost like a gunshot, and when enough shrimp snap at once, the din can be louder than the roar of a passenger jet flying overhead.

Centennial E3 – Rifts Beneath the Ocean Floor
Kathy Crane is a true adventurer. As one of the first women in the field of marine geophysics in the 1970s, she hypothesized and then helped discover the existence of hydrothermal vents on the Galápagos Rift along the East Pacific Rise in the mid-1970s and was one the first people to see many of the strange creatures that make their home in this improbable environment.

E13 – Waiting for Poop
There are lots of weird, dirty jobs out there. Roadkill collector. Deodorant tester. Catfish noodler. Chicken sexer. But what about… whale poop collector?
