An independent podcast about critical issues in higher education. All episodes are free to download and share.
------
An academic citizen is anyone who is part of the higher education community. They are engaged in pedagogy or research or both, and are committed to furthering knowledge, education and the advancement of society from their disciplinary position.
An academic citizen sees their work in higher education as a public project, both in terms of being partially funded by taxpayer money, and in terms of the contributions they wish to make to the world around them.
Although citizenship implies an exclusive form of belonging, here we use it to signal the role of academic work in collective life in a non-exclusionary way, and to anchor it in a public project to which all humanity belongs.
We create knowledge not only for our individual benefit but for the benefit of all.
The Academic Citizen is an independent podcast series produced and funded in its second iteration by the South African Research Chair in Science Communication in 2022. It was originally supported by the Academic Staff Association of Wits University (ASAWU) when it was first established in 2016.
In this final episode of the season, we focus on the intricate web that connects life on our planet. We zoom out to hear about how Marion Island is a location for space science, and then zoom in to learn how SA Agulhas II and Marion Island serve as extraordinary training grounds for the next generation of scientists. Young researchers learn technical skills of their fields and also how to observe, question, and collaborate in environments that demand accuracy and humility. South African research plays a crucial role in the global community of Antarctic and sub-Antarctic science. It provides an essential piece of the puzzle in understanding how ecosystems across the globe are interconnected. What happens in this isolated archipelago ripples outward, informing our knowledge of climate, biodiversity, and the delicate balance that sustains life.
This episode invites listeners to explore how scientific knowledge, cultural understanding, and lived experience come together in the pursuit of discovery. And perhaps the most powerful insight from the Marion 2025 voyage is that every scientist spoken to views their work not as an individual effort, but as part of an intergenerational project. It is a testament to the episode's theme: everything is connected.
It has been an absolute pleasure to work on this season and to share the journey to Marion Island. We extend our gratitude to Prof. Charne Lavery and Prof. Jean Brundrit for conceptualising and leading the SANAP Artists and Writers Programme, and for the valuable access, experiences, and insights this initiative has provided. We also like to thank all the guests who agreed to be interviewed for this season.

73. Swimming, Blowing, Glowing
The ocean surrounding Marion Island is a breathing wilderness - a vast and mysterious realm where familiar giants coexist with tiny creatures that emit an almost magical light. These diverse beings move through the water in intricate ways that we are only beginning to understand. On the surface, it may seem simple and ordinary, but beneath the steel-blue waves lies a vibrant, lively world teeming with life and secrets waiting to be uncovered.
We follow the creatures we recognise as they slice, glide, and hunt through the sub-Antarctic waters, and we uncover the vital role of microscopic organisms that quietly sustain the entire ecosystem and keep the heartbeat of the ocean alive. This episode encourages curiosity to witness an ocean in transition, from iconic species navigating these waters to the importance of microscopic life, and how its chemistry and rhythms are shifting with profound consequences for the creatures that call it home.

72. Antenna, Fur, Feathers
Marion Island may be thousands of kilometres from the South African mainland, but it buzzes with activity: tiny, and large fluttering, crawling, nesting, scurrying movements. In this episode, we dig deeper into the island’s living world to explore the extraordinary creatures that inhabit this subantarctic terrain. From insects smaller than a fingernail to birds that undertake vast journeys across the Southern Ocean, and even the mice whose presence has altered the ecosystem, we examine some of the animals that live in this harsh environment.
Why are these species important? What makes their survival so exceptional? And what insights are scientists gaining about biodiversity, adaptation, and ecological vulnerability at one of the planet’s most remote research locations? Using vivid descriptions, expert knowledge, and field observations, this episode explores the diverse life forms coexisting on this windswept island and the vital research aimed at protecting them. We start with the tiniest inhabitants and gradually broaden our focus to include some of the feathered and furry creatures that define life here.
We thank the following guests on this episode:
-Ms Camilla Smyth, Mr Chandler Patel, Mr Andile Khuzwayo, Ms Janu Rau, Ms Rhiannon Gill and Ms Eleanor Weideman from the South African Polar Research Institute.
