    Geology Meets Deep Tech - Danielle Bennett

    On this episode of Planet Geo, we welcome Danielle Bennett—a startup operator with a venture capital background (and not a geoscientist by training) who’s been talking with tons of geologists, hydrogeologists, and engineers while helping build a geoscience-adjacent mapping company at Deep Earth Tech. Danielle shares how growing up with entrepreneur parents (who ran a groundwater-focused engineering firm) shaped her path, why she started a social-impact company in college, and how she moved from corporate finance to FinTech and then into venture capital for about six years.  They dig into what she’s learned from working with the geoscience community—friendly, non-confrontational, and highly opinionated—and why geoscientists may be slower to found startups (a strong perfection/excellence culture and highly localized expertise).  Danielle breaks down “deep tech” in practical terms (asset-heavy and/or science-and-engineering-driven tech), why capital is moving earlier into deep tech, and how VCs are increasingly pulling innovations from universities and incubators. The conversation also gets into which geoscience-adjacent areas feel investable (like shallow geothermal heating/cooling, critical minerals, and renewables) and why groundwater can be harder to fund due to public-agency buying cycles and complex bureaucracy.  Danielle closes by defining key funding terms—bootstrapping, debt financing, private equity, and venture capital—plus what VCs look for (why now, why this team, and scale) and common red flags (unclear messaging, weak grasp of numbers, and unjustified mega-rounds).

    Here Be Dragons - Exploring the Unknown with NASA Ames Chief Scientist for Innovation Dr. John Stock

    In this riveting episode, we catch up with Dr. Jonathan Stock, Chief Scientist for Innovation at NASA's Intelligent Systems Division. We dive deep into the realms of geosciences and discuss how innovation can transform our understanding of the Earth and beyond. From quantum gravity gradiometers to AI-driven geophysical mapping, Dr. Stock reveals the tech that could redefine geospatial exploration. We also ponder why geosciences lag behind other fields in entrepreneurship and innovation and how cross-disciplinary collaborations could be the game-changers we need. Join us as we weave through tales of awe-inspiring geological discoveries and the frontier spirit that keeps the field exciting. Download the CampGeo app now at this link.

    Banded Iron Formations - A Deep Dive

    In this episode, we bring you a riveting Q&A session with GeoGirl Dr. Rachel Phillips and Dr. Joshua Davies, both experts in geology who explore the mysterious world of banded iron formations (BIFs). We dive deep into what BIFs are, when they formed, and their significance. Josh unpacks the debated origins of these rocks, discussing how they may be the most hotly contested rocks in the geological world due to our limited understanding of their formation process, despite their voluminous presence on Earth. We touch on how BIF layers represent cycles influenced by Milankovitch cycles, and whether microbial activity plays a role in their formation. Josh explains that while BIFs peters out around 1.8 billion years ago, there are unique conditions and debates on secondary processes that impact our current understanding. We humorously explore modern analogs, like weird anoxic lakes, and laugh about how our Earth would need a huge meteorite impact to revert to BIF-forming conditions—a scenario we're not quite rooting for! Finally, we ponder the possibility of extraterrestrial BIFs, symbolizing our endless curiosity about space and deep time. This one’s a dense, iron-packed dive for sure—just like BIFs!

    How to Identify Rocks - Rerelease

    Welcome back to Planet Geo, the podcast where we delve into the wonders of our planet's geology, how it works, and why it matters. In this episode, part three of our holiday re-release series, we’re breaking down the basics of rock identification and collection techniques. Chris and I tackle the popular question: how do you identify rocks? We provide a general strategy perfect for budding rock hounds and outdoor enthusiasts. Plus, stay tuned for new episodes and exciting modifications coming to Planet Geo’s sixth year, including deep dives with Dr. Rachel Phillips and geology news segments with Dr. Josh Davies. Follow us on social media and check out our Camp Geo mobile app for tons of free, cool content!  Today's discussion dives into the nitty-gritty of rock identification. We walk through our methods, distinguishing between sedimentary, metamorphic, and igneous rocks, and share handy tips like carrying a magnifying lens, a little acid bottle, and a hammer to reveal a rock’s true identity.  We also chat about reliable resources like the Roadside Geology series to help you understand the geology of specific areas. We emphasize the importance of breaking rocks open to see fresh surfaces and narrow down your identification process methodically. Remember, even seasoned geologists take samples back to the lab for further analysis! Finally, we talk about the value of curiosity and the learning process. Whether it’s being the 'annoying student' who asks all the questions or participating in practical exercises like visiting a gravel pit, there’s a lot to gain from hands-on experience. We encourage you to do some research before your next trip and embrace the joy of discovery. If you have more questions or need help, hit us up at Planet Geo Cast on Gmail or on social media.
