	The Power of Plankton	21 Jul 2026	00:25:30
Plankton are the foundation of life on Earth, evolving and shaping the planet over billions of years. In this episode, Vincent Doumeizel, author of The Power of Plankton: How Plankton Made Life On Earth Possible and Why It’s Key To Our Future, talks about plankton and why it is fundamentally important for the survival of life on Earth as we know it. We talk about some of the engaging stories in the book, for example, why did Alain Bombard cast himself adrift in the Atlantic Ocean in rubber dinghy with only a plankton net? Are we Martians? And why hope will play such an important role in the fight to protect ocean biodiversity. The Power of Plankton, the new book from Vincent Doumeizel, bestselling author of The Seaweed Revolution, is published by The Book Social. Thanks for listening!

	Microplastics in a changing environment	15 Jun 2026	00:33:08
Microplastics are present in the water we drink, the food we eat, and the air that we breathe. In this episode we meet Dr Alice Horton, Senior Research Fellow at the Marine Biological Association and an expert in aquatic microplastic pollution. We have been leaking plastic into the environment for the last 60 or so years and the amount entering the ocean is predicted to triple by 2040. But, as Alice explains, we still understand little of the long-term implications for ecosystems and human health. Alice's research at the MBA is specifically focusing on how microplastics interact with the diverse and complex mix of chemical and climate stressors and how different species will respond under changing global environmental conditions. We also discuss what scientists and policy-makers are doing to tackle microplastics and what we as individuals can do to reduce our exposure.

	Inspiring women: crossing an ocean for the ocean	18 Mar 2024	00:35:37
We are joined in this episode by Noelle Helder, marine ecologist, and member of the four-woman Salty Science rowing team that crossed the Atlantic to make a positive contribution to inclusivity in marine science. Representing three generations of marine scientists, Isabelle Côté, Chantale Begin, Lauren Shea, and Noelle rowed 3,000 miles across the Atlantic in an 8.5 m boat. Noelle describes how she and the team prepared for this epic of endurance, kept their morale high, and worked as a team under the most extreme conditions. They not only won the women's division and came 7th out of 37 boats that finished the race. On the way they endured days of 20-foot waves, encountered sharks, tuna, and flying fish, and tried not to think about the consequences of a marlin strike. Noelle’s description of the sometimes hair-raising journey is refreshingly deadpan – perhaps unsurprising for a self-confessed lover of ‘type II fun’. But beyond testing themselves in the open ocean, the reason the team took on the challenge was to raise support for marine conservation education, and support access for less privileged people to enter careers in marine science. We hope you enjoy this episode as much as Lize and I did. https://saltyscience.org/ https://www.worldstoughestrow.com/the-atlantic/ Text us your comments and feedback Thanks for listening!

	First to the feast - when open ocean hunters converge	20 Oct 2023	00:29:48
A shoal of sardines comes under attack from all sides as some of the ocean's most spectacular predators converge to take their fill. But which species do best and how do they interact with their competitors? How can scientists even study such a dynamic and ephemeral event? Alicia Burns joins us to talk about the challenges and rewards of getting up close and personal with feeding aggregations in the clear waters off Baja California, Mexico. The purpose of this exciting research is to understand the hunting success of individuals, specifically, of blue marlin and sea lions and other predators in open ocean multi-predator aggregations. Learning how resources are shared helps understand this extremely productive ecosystem and the threats it faces through exploitation and climate change. Alicia is a behavioural biologist whose research interests include the mechanisms driving animals' social organization. She is part of an international and multi-disciplinary collaboration with scientsist from Departamento de Pesquerías y Biología Marina, Instituto Politécnico Nacional, Centro Interdisciplinario de Ciencias Marinas (CICIMAR-IPN), La Paz, Baja California Sur, 23096, Mexico led by Jens Krause, Head of the department of Fish Biology, Fisheries and Aquaculture at Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB).

	Why inspiration is the ocean's greatest untapped resource	24 Jul 2023	00:37:27
Ever since humans began making things, we have been looking to nature for inspiration: Leonardo Da Vinci designed flying machines inspired by birds, and burs (seeds covered in hooks) inspired the invention of velcro. Marine natural compounds are three to four times more likely to yield successful drugs compared with terrestrial ones. In 2022, there were over 17,000 new marine natural products discovered. Leading marine biologist Robert Blasiak joins us to discuss the magical ingredients of marine biomimetics. With an emphasis firmly on learning from nature and extracting only ideas, Robert and colleagues from the Stockholm Resilience Centre take us on a fascinating exploration of the deep sea, how we must value it, and why the benefits of exploration may outweigh those of extraction.

	Meet the gene genies! The Darwin Tree of Life project	22 Sep 2022	00:43:39
You have probably heard of Charles Darwin (he got there first with his theory of evolution by natural selection) and DNA. But few of us can explain what a genome is and why genomes are so important. In this podcast we ask Kes Scott-Somme, a Marine Biological Association scientist who works on the marine part of the Darwin Tree of Life project (DToL), why so many people are interested in the genomes of marine organisms, and what is a genome, anyway? As part of a global drive to describe the genetic make-up of life on Earth, DToL is cataloguing the genomes of 70,000 species in Britain and Ireland. Kes also gets around to talking about careers in marine biology, taxonomy, and the importance of natural history. Join this engaging discussion and find out how building a vast catalogue of genomes is relevant to human health, and dealing with the climate and biodiversity crisis.

	The fall of the great ocean farmers: blue and fin whales in the Southern Ocean	27 May 2022	00:51:46
The Antarctic blue whale is the biggest animal that has ever lived. In the 20th century, humans harvested 99 per cent of them. In this episode we welcome Matthew Savoca and Conor Ryan. Matt is interested in how animals might teach us about human impacts on the environment, and how we might reverse those impacts. Conor is a cetacean expert and photographer who describes the Southern Ocean as "the oceanic heartbeat of the planet". Both are hugely knowledgeable about how the Southern Ocean ecosystem works. If you ever wondered how many blue and fin whales there are now, how many were lost to whaling, and how that impacts us, listen on! This is a fascinating conversation with two young and engaging scientists. Text us your comments and feedback Thanks for listening!

	Small-scale is beautiful: building relationships for a sustainable inshore fishing fleet	13 May 2026	01:08:15
In this episode, we meet social scientist Sarah Coulthard, and fishermen George Lamplough and Bally Philp who discuss issues facing small-scale fishers. Over 30% of global marine catch comes from small-scale fisheries, contributing to global food security, livelihoods, and resilient communities, and yet the UK's highly valued inshore fishing fleet is in decline. Is this "the last chance saloon for the small-scale fishing industry" ? Sarah, Bally, and George explore the reasons for the decline, discuss fishers' lived experiences, fisheries management and public perceptions. They also discuss the priorities for actions to help ensure a viable future for the fleet. The podcast follows on from the special edition of The Marine Biologist magazine which focuses on inshore and small-scale fisheries. Our guests are involved in the Inshore and Small-Scale Fisheries consortium (ISSF), a group which aims to identify the drivers of decline in the UK fleet, identify what can be done to support fishing lives, and support fishers to be active partners in decision-making. Find out about the work of the ISSF Consortium here. See the press release which details the national symposium for inshore and small scale fisheries, held in February 2026 in Newcastle.

	An illusion of protection? Marine Protected Areas with Professor Callum Roberts	24 Apr 2026	00:37:15
"We need to consider what an area of sea is capable of when given real protection." Professor Callum Roberts is a world authority on marine protected areas (MPAs). In this podcast, we talk about marine protected areas both in national waters and the high seas. What needs to change in the UK's current approach to marine protected areas (MPAs), and how can the network support healthy and productive fisheries, producing gains, not just costs for the fishing industry? To have a vision for future seas, we have to look back: this is where the conversation turns to shifting baselines and a fascinating look at the momentous changes that have been wrought on the seabed of the Northeast Atlantic over the past 200 years. We also discuss the growing awareness of seabed carbon and the role of MPAs in supporting climate regulation. Callum is also an author, perhaps best known for The Unnatural History of the Sea (Island Press) which charts the effects of 1,000 years of exploitation on ocean life. See also: convexseascapesurvey.com The Convex Seascape Survey project is dedicated to filling knowledge gaps on how the ocean and climate are connected, to inform effective action against the climate crisis.
