Seaweed People

This one’s for you if you’re interested in biochar, giant kelp, marine engineering or thinking about seaweed as a solution to a whole lotta problems 🛠️🐟Adam Brancher is a Principle Marine Surveyor and the  Founder of Southern Ocean Carbon, which aims to mitigate the impacts of climate change through responsible seaweed mariculture and bio-mitigation around aquaculture farms. We touch on a few of the exciting projects his team is working on across the world in this episode, such as growing seaweed for bioplastics, offshore mariculture, IMTA and seaweed for food security. You can find Adam and the Southern Ocean Carbon team here or on socials @southernoceancarbon.

You’ll love this ep, I just know it 🐋🦅 It’s for you if you like baby seahorses and migrating whales, if you live in a coastal city, if you've heard about wildlife coming back into harbours during lockdowns, or if you want to know what a strong collaboration between Indigenous knowledge-holders and western science looks like. Robert Cooley is a Senior Ranger and leader of the Gamay Rangers, an Indigenous ranger team that cares for country on Gamay, or Botany Bay in Sydney, and on conservation land owned by the La Perouse Local Aboriginal Land Council. Since 2019, the Gamay Rangers team have been regenerating coastal habitats, protecting marine mammals, providing food for vulnerable people during Covid lockdowns and connecting local communities to Sea Country in Australia’s biggest city. You can find Robert and the Gamay Ranger team on socials @gamayrangers.

This one’s for you if you’re into craft beer, you like dreaming up side hustles with your mates, you’re a chef wanting to experiment with kelpy umami or if you’re an aspiring seaweed farmer 👩🏽‍🍳🍻Cam Hines and Brent “Bert” Cross are two of the three founders of Southern Seagreens. From backgrounds in craft beer and naval diving, they joined forces with Rob (the third, a scientist) to learn how to farm native kelp at their sea farm down in Flinders, Victoria. They also hunt wakame, one of the world’s most invasive (yet delicious) species, and turning it all into tasty treats. You can find Cam & Bert via the Southern Greens website or socials.

This is maybe as seaweed peopley as it gets. It’s for you if you want an overview of kelp forests, if you’re into rewilding and sea otters, if you have any kind of skill and want to put it toward conserving kelp, if you like the sound of a national marine gardening day or if you just want to hear about a big, impressive enviro movement 🦦⚡Aaron Eger is the Founder and Program Director of the Kelp Forest Alliance, a global community of kelp restoration and conservation practices and research that evolved from his PhD. He was the lead author of the first ever kelp restoration guidebook and facilitated the creation of the Kelp Forest Challenge, a global mission to protect and restore 4 million hectares of kelp forests by 2040.You can find Aaron at UNSW or via the Kelp Forest Alliance website.

This one’s for aspiring seaweed farmers, kelp ladies and anyone who loves a good seaweed yarn. We’re talking seaweed babies, wild harvesting, kelp farming and Ecklonia radiata - the backbone of the Great Southern Reef, also known as common kelp, leather kelp, thorny kelp or golden kelp. Jo Lane has a background in marine science and sustainable coastal environments and is the owner of Sea Health Products, which make small-batch kelp products on the South Coast of NSW. She’s currently working on asparagopsis in South Australia as a research Lead with the Australian Sustainable Seaweed Alliance and, as a quite serious “side hustle”, she’s also developing kelp seedstock with a view to get kelp farming and restoration projects happening in Australia.You can find Jo on LinkedIn.

Ooh yes, today we are hearing all about oysters! Also seascape restoration, pseudo-mangroves, living seawalls and a good use for potato chip waste. This one’s for you if you’ve heard that 85% of global oyster reefs are degraded thanks to humans (yikes) and if you want to know how we can help bring them back 🦪👻Professor Melanie Bishop is a coastal ecologist who researches changes to temperate environments like coastal erosion, nutrient enrichment, and marine urban sprawl, as well as engineering interventions to create habitat and conserve native biodiversity in degraded seascapes. She co-leads the working group of the World Harbour Project as well as the Living Seawalls Program, which is part of the Project Restore with SIMS. You can find Melanie at Macquarie University.

Macrocystis! This episode is for you if you’ve always dreamt of diving through the iconic giant kelp forests in Tasmania, and if you’ve heard that they’ve completely disappeared, but also and if you want to hear about divers and scientists coming together to revive them 🏥🌱 Mick Baron is an avid diver, storyteller, underwater videographer and co-owner of the Eaglehawk Dive Centre. He’s spent 20 years as a scientific observer on fishing vessels in sub-Antarctic to tropical waters, and is an active campaigner for local marine conservation. You can find Mick at the Eaglehawk Diver Centre.

This episode is for you if you like rivers and oceans, if you want to connect deeper to Sea Country, if you live in Australia or another country where the dominant narrative of the ocean stems from a colonial or European history. Maybe you’re an educator or social worker, or you just love being outside. Rhiannon Mitchell is a First Nations woman from the Mununjali people of Beaudesert, who grew up on Gumbaynggirr Country. She’s the founder of Saltwater Sistas, where she teaches young Aboriginal women and girls about the marine environment through mentoring, workshops, ocean conservation and connecting to Country. This episode briefly touches on land theft and other themes of colonisation, so please listen with care. You can find Rhiannon on socials @saltwater__sistas and read more about her programs and how you can get involved or support her work through her website.
