Welcome to the Tybee Island Marine Science Center podcast, recorded in the Ship Watch Loft. On this episode, host Jessica Leigh Lebos welcomes Brooke Chase, host of the Simply B. Sustainable Podcast and co-organizer of Green Drinks Savannah, a monthly gathering (second Tuesday at 6:00) for ecologically minded community and action.

Chase shares how she and Chloe revived Green Drinks after reconnecting with a former organizer and describes the event’s growth and rotating locations and topics, including an upcoming Forsyth Park tree walk.

She discusses her lifelong drive to reduce waste, emphasizing that imperfect efforts by many matter more than perfection by a few, and frames consumer choices as “money is your vote.” Practical tips include “refuse, repair, reduce, reuse, recycle,” avoiding plastic and styrofoam, composting (highlighting Core Compost), using ABC Glass recycling in Thunderbolt, buying secondhand via Goodwill, Facebook Marketplace, and Buy Nothing, and creating native pollinator gardens. They also note concerns about AI’s water and energy impacts.

Host Jessica Leigh Lebos sits down at the Tybee Island Marine Science Center with Cloe LeMaire, an environmental scientist and the Savannah Reuse System Outreach Coordinator for Savannah Riverkeeper. They dive deep into the major pressures currently facing the Savannah River, from port-driven growth to the rapid explosion of regional warehouses.

What We Cover in This Episode

• The Warehouse Boom & Public Data: Cloe walks through a public GIS dashboard built alongside 100 Miles and Ogeechee Riverkeeper that tracks developers, permits, square footage, and timelines—with expansion plans heading into South Carolina.
• Trash Traps & Brand Data: Discover how 12 NOAA-funded trash traps installed since 2024 are capturing stormwater litter and tracking specific brand data, revealing a heavy footprint of takeout-related styrofoam.
• Reusables & AI Data Centers: Cloe shares updates on designing an open-loop reusable cup system for Savannah and discusses the delicate organizing happening around a proposed AI data center along the river.
• River Science & Restoration: The conversation rounds out with a look at ongoing oyster research, baseline water-quality monitoring supporting the restoration of river cutoff bends, and upcoming channel deepening and widening proposals.

Get Involved Cloe invites listeners to join Savannah Riverkeeper, make use of their community reporting tools, and roll up their sleeves for a cleanup at Lake Mayer Park on September 12th.

Host Jessica Leigh Lebos welcomes Tybee Island Maritime Academy science teacher and assistant principal Katie Holliday to the Tybee Island Marine Science Center podcast to discuss TIMA’s place-based, maritime-centered K–8 curriculum and daily experiential learning on Tybee’s beach and marshes.

Recorded from the Ship Watch Loft at Tybee Island Marine Science Center.

Holliday explains TIMA is a lottery-based charter school within Savannah-Chatham County Public School System that integrates STEAM through project/problem-based learning and community partnerships, including a NOAA Ocean Guardian native plant garden planted at the Marine Science Center with support from All The Buzz nursery. They highlight TIMA’s MATE ROV robotics program (earning high-school engineering credit) and a recent second-place finish.

Holiday shares her 17-year teaching journey and stewardship goals, discusses the school’s purchase of the former Thunderbolt Elementary to potentially expand beyond Tybee, notes TIMA’s established cellphone collection policy, and outlines thoughtful approaches to student AI use and STEAM recertification.

Host Jessica Leigh Lebos records the Tybee Island Marine Science Center podcast from the Ship Watch loft and interviews Kristen Zemaitis, a biologist with the Caretta Research Project, a nonprofit loggerhead sea turtle research program on Wassaw National Wildlife Refuge that has monitored nesting for 54 years.

Zemaitis explains how saturation tagging shows individual females can lay up to eight nests per season about two weeks apart, and discusses natal homing, genetics work with UGA and building paternal family trees from embryo DNA.

She describes night patrol fieldwork from May–August using volunteer teams, data collection (measurements, PIT/metal tags, blood/skin/cloacal samples, one egg per nest), nest relocation and predator screens, and challenges like heat, bugs, storms, coyotes, and alligators. The episode covers nesting cycles, TED impacts, satellite tagging, volunteer registration, fundraising, and education outreach.

Host Jessica Leigh Lebos welcomes Dr. Catherine Edwards, a coastal physical oceanographer and professor at UGA’s Skidaway Institute of Oceanography, to discuss how coastal ocean physics shapes ecosystems and forecasting.

Edwards describes her path from music and Spanish into applied physics and oceanography, and explains her work measuring temperature, salinity, density, tides, waves, and currents across Georgia’s wide continental shelf using research vessels, seafloor instruments, and autonomous gliders. She connects coastal processes to carbon export and sequestration, the Gulf Stream’s influence, and why real-time glider profiles improve hurricane intensity forecasts, including rapid intensification risk.

Edwards also details using quiet gliders with hydrophones to detect North Atlantic right whale calls, confirm detections with analysts, and send alerts through NOAA to tools like Whale Alert and Whale Map to help slow ships. The conversation includes river-driven events like undammed flood pulses reaching Gray’s Reef and a myth-busting aside about toilet swirl direction.

Host Jessica Leigh Lebos welcomes Dr. Kathryn Craven, a Georgia Southern University professor, Tybee Marine Science Center board trustee, and researcher known for work with loggerhead sea turtles and diamondback terrapins.

Craven shares her path from growing up near the Northeast coast to landing a sea turtle research job on Jekyll Island in 1991, including renewing flipper-tagging efforts. She discusses Georgia nesting-season monitoring, increasing loggerhead nest numbers linked to conservation measures such as shrimp fishery regulations and beach protections, and emerging challenges like rising coyote predation, plus mitigation using nest screening and predator control (including feral hogs).

Craven highlights research on nest microbiomes (fungi and bacteria) and findings that most unhatched eggs show fertility. She explains the TERPS head-start program incubating terrapin eggs and releasing hatchlings to offset female road mortality on Highway 80. The conversation also covers teaching evolution misconceptions through student drawing, earlier humpback whale work on bubble-net feeding, and new collaborative DNA-based lionfish research tied to lionfish rodeos and outreach.

Host Jessica Leigh Lebos welcomes back Joy Davis, the Tybee Island Marine Science Center’s permanent artist-in-residence, a biologist-artist known for the Center’s three-dimensional North Atlantic right whale model of “Smoke” and life-size sea turtle models.

Davis discusses how homeschooling, travel as an Air Force brat, and a blended arts-and-science college path shaped her career, plus her move to Savannah/Tybee through teaching, bartending, ocean-driven volunteering, and eventually working at the Science Center. She explains the research and collaboration required to make the whale anatomically accurate, including reproducing Smoke’s unique callosities and adding 3D-printed “lice.”

Davis also describes work with Animal Exhibits and Designs creating zoo/aquarium environments, new Tybee exhibits like a sit-in osprey nest, four tiled ecosystem murals (marsh, maritime forest, dunes/beach, and Gray’s Reef), and a newly approved backyard pollinator and memorial-style garden.

Host Jessica Leigh Lebos is in the Ship Watch Loft of Tybee Marine Science Center with Captain Jimmy Armel, former Army Ranger and founder of the Knot Lucky Foundation (K-N-O-T), which offers free fishing trips for active-duty service members and veterans (and immediate family) to support healing, connection, and purpose.

Armel shares his own struggles after leaving the military, including alcoholism, brain damage, and suicidal crises, and explains how fishing and later ibogaine treatment led him to shut down his for-profit charter to run the nonprofit full time. He describes transformations he’s witnessed, including posting $75,000 bail for a fellow Ranger, housing him, and building a customized mental health plan.

The episode also covers launching from Savannah Boathouse, ocean-based restoration, great white shark satellite tagging with Gray Fish Tag Research, fundraising via an annual barbecue, and ways to donate at knotlucky.org.
