This is Marine Conservation | ocean science, stories, and solutions to protect our blue planet

Ep. 20: Green crabs aren't native to New England, so can we use an "eat them to beat them" approach? Dr. Gabby Bradt has spent more than a decade trying to find out.

Gabby is the Fisheries and Aquaculture Extension Specialist for UNH Cooperative Extension and New Hampshire Sea Grant, and she’s been on my guest wish list since before this show had a name. She interned for my dad at the EPA back when I was a kid watching him tow a boat up to Maine for fieldwork (and deciding that looked way better than an office). Years later, we ended up working across the hall from each other at UNH. 

From a PhD in squid biology to becoming known as the "green crab lady" (to her great annoyance), Gabby has had an exciting and varied career throughout the marine sector.

In this episode, we get into:

• How European green crabs got here 200+ years ago, and why it took so long for anyone to care
•  Why Gabby doesn’t think wiping them out is the goal anymore
•  The two summers she spent photographing crabs to figure out when they’re about to molt (and why that matters for your dinner plate)
•  Why the word “invasive” was getting in the way of people eating them
•  The Great Green Crab Hunts, where anyone from toddlers to grandmas can help
•  Her honest take on careers off the tenure track, learning to say no, and bringing your kids along for the ride
•  What it’ll actually take to turn green crabs into a real market

Gabby is an absolute force in the world of marine science and someone I've admired and looked up to for a very long time. She's a riot, a joy, and an inspiration. I hope you enjoy this episode as much as I did!

Ep. 019: Ever wondered about the life of an oyster before it hits your plate?

This week's guest is oceanographer Jacqueline Rosa. She spent a year and a half monitoring the surface and bottom of the bay, plus six months raising oysters in three kinds of farming gear. One of those was Flip Farm, a New Zealand–designed system that's getting Rhode Island oyster farmers' attention. She did all of this after a decade away from school, working at marine science nonprofits and in outdoor education.

In this episode, we talk about:

• What an oyster "seed" actually is (you'll hear me realize my lack of knowledge on the topic in real time)
• The farmer who knew about a problem at his site before any sensors did
• Which gear lost the most oysters, and the two culprits behind it
• Whether ocean acidification is showing up in Narragansett Bay
• The cold email that led to her funded master's project
• Why her ten years in the workforce helped her succeed as a grad student

Stick around to the end for what's giving Jacque hope for the ocean right now. It's a lovely one :)

Ep 018: Fishing charter captains don't care about conservation, right? Wrong.

Coral Aiello started working on her dad's charter boat as a 14-year-old mate. Sixteen years later, she's the captain and her dad works the deck. 

In this episode, Coral shares why she believes fishers care about the ocean more than most, how she brings fish tagging aboard her charters, and what her seat on the Rhode Island Marine Fisheries Council has taught her. Plus: warming waters, the "Professional Hooker" story, and going from law-school plans to captain's license.

We talk about being a woman in a male-dominated industry, the reality behind the "dream job," and how she folds conservation into every charter. This one is honest, funny, and full of heart. 🎣

Ep 017: Melissa Hobson is one of the most published ocean writers around, with bylines in National Geographic, BBC Wildlife, Scientific American, The New York Times, and The Guardian. After she was peer-pressured into learning to scuba dive on the Great Barrier Reef, she slowly transitioned her career from PR to writing about the oceans. 

There are so many options for building a marine career that isn't "scientist," and Melissa shows us just how incredible a career in ocean writing can be. 

We talk about the portfolio-less cold email that landed her the cover of a dive magazine, the one question every good pitch has to answer (it works for job applications too), and how ocean stories break days before the rest of the world hears about them.

 She also talks about her "conservation Trojan horse" trick for slipping the important stuff into a fun animal story, where she really lands on AI as someone who writes for a living, and the citizen science projects that let you help the ocean from your laptop, even if you're hundreds of miles inland.

If you've ever wanted to work in the ocean space but not as a scientist, this one's for you.

Ep 016: Dr. Liberty Boyd went to college to become a teacher, but walked out a sea turtle scientist. In this episode, we get into the decade-long question that pulled her in: what are sea turtles actually doing for 99% of their lives when they're not up on the beach nesting?

For her Ph.D. research, Liberty tracked turtles across the Bahamas, Bermuda, and Australia using cameras, underwater microphones, and Apple-Watch-style motion tags. She breaks down, in plain language, how each one works and what they revealed. We talk about turtles that steer around boats, why the jellyfish-eaters roam so much farther than seagrass munchers, the harmful algal bloom research she's worked on most recently, and the postdoc distinction she wishes someone had explained to her sooner.

She also shares a piece of career news you're hearing here first, and the decade-long relationship behind it.

Whether you're chasing a marine science career or you just love turtles, this one's for you. 🐢

Ep 015: Did you know part of Narragansett Bay was closed to shellfishing since before World War II, and that it only reopened a couple of years ago?

I didn't fully understand what that comeback meant until I sat down with Chris Dodge, the Narragansett Baykeeper at Save The Bay. Chris holds one of only about 300 Waterkeeper positions on the planet, which basically makes him the eyes, ears, and voice of the Bay. I wanted to know what that job actually looks like day to day. Somewhere between raw sewage, a secret tunnel under Providence, and what he calls a "biomagnified bomb of bacteria," I ended up way more hopeful about the future of our Rhode Island's bay than when we started.

In this episode, we get into:

• What a Baykeeper actually does all day (spoiler: no two days look alike)
• Why, in Rhode Island, you often have no way of knowing when sewage hits the water you swim in
• The 3-mile tunnel under Providence that brought shellfishing back after 80 years
• How more than half the Bay's watershed sits in another state
• Chris's advice for breaking into marine conservation when the big orgs feel out of reach

Whether you're chasing a career on the water or just love Narragansett Bay, this one will leave you a little more optimistic about what's possible. 🌊

Ep 014: What happens when you see something that changes the entire course of your career... in the first six minutes of a Netflix show?

In this episode, I sit down with Imani Black, founder and CEO of Minorities in Aquaculture (MIA). Imani spent about five years as a commercial oyster farmer on the Eastern Shore of Maryland before Googling "how to start a nonprofit" in 2020 and building what's now a global network of around 600 members. She's an oyster enthusiast, a self-described dreamer and doer, and one of the most honest voices I've had on the show. She's keeping it real about what it takes.

Here's what we get into:

• The Netflix moment that rerouted Imani's entire career
• How a cold email (with barely any punctuation!) changed everything
• Why she says aquaculture is conservation, not separate from it
• The article that "caused quite a stir" and the culture shift she's pushing for
• Why representation is a first step, not the finish line
• What "killing every version of yourself" has to do with building something new

Whether you're oyster-curious or dreaming up your own path into marine conservation, this one will leave you inspired. 🦪

Ep 013: Can film move the needle for marine conservation? The answer is an unequivocal YES.

Underwater cinematographer Erick Higuera is not only a genius with a camera, but he's also a marine biologist and passionate advocate for his home, the Mexican Pacific. He's been diving these waters since 1997, meaning he's had a front row seat to some of the worst environmental decline in the region, but also some incredible successes. We chat about some of these amazing examples of ocean recovery and protection, including the marine protected area in Cabo Pulmo and Revillagigedo National Park, North America's largest fully protected marine reserve.

Erick also shares his not-so-linear path into the world of marine biology and cinematography via the dive industry. He reveals some heart-stopping underwater encounters with humpback whales and orcas, and shares how he balances his vitally important work with his family life.

And of course, we talk about the latest project Erick worked on: Hammerhead Sharks Up Close with Bertie Gregory. It's streaming now on Disney+.

Ep 012: Sustainable seafood sounds simple... until you're standing at the counter, staring at five kinds of white fish with zero idea what to buy. 

In this episode, I'm breaking down five low-effort, high-impact tips for making better seafood choices, no marine science degree required! 

In this episode, we chat about why eating local matters, what eating low on the food chain actually means, which eco-labels are worth trusting (and which to take with a grain of salt), why ocean plants deserve a spot on your plate, and one easy swap you can make as soon as this week. 

These changes are small, but they compound. You don't have to overhaul your whole diet to make a difference. By the end, you'll have at least one concrete habit to bring to the seafood counter next time you shop.

Ep 011: What would you say if someone told you there was a thriving coral reef in a bay full of industrial pollution, sediment runoff, and unusually warm water — and that it had been there for many years? You'd probably say that's impossible. Juli Berwald said the same thing, and then she got on a plane to Honduras to see it for herself.

Juli is an ocean scientist, award-winning author of Spineless and Life on the Rocks, and founder of the nonprofit Tela Coral. In this episode, we get into the mystery behind Tela Bay's improbable elkhorn coral population, the "Flonduran" coral hybrids that are making waves in Florida reef restoration, what it actually takes to build a biobank from scratch in a foreign country, and how a violinist helped raise $86,000 for coral conservation through the power of live music.

We also talk about science writing — how Juli went from textbooks to National Geographic, why she writes memoir into her science books, and what she'd tell anyone who wants to do what she does.

This one genuinely made me want to book a flight to Honduras. I think you'll feel the same way.
