Celebrating MPA Day 2025: Ocean Protection Needs Human Connection
Today, on Marine Protected Areas (MPA) Day, we join a growing global community in celebrating the ocean’s incredible biodiversity and the sanctuaries that safeguard it. This year’s theme, “Ocean Protection Needs Human Connection”, is a powerful reminder that the health of our oceans is inseparably linked to the actions and commitment of people.
MPA Day, shines a spotlight on the importance of Marine Protected Areas in ocean conservation, sustainable development, and the well-being of communities across the globe. The date—1 August—honours the momentous 2019 declaration of 20 new or expanded MPAs in South Africa. Since then, MPA Day has grown into a United Nations Ocean Decade-endorsed international movement.
The Prince Edward Islands MPA: South Africa’s Sub-Antarctic Treasure: In the remote reaches of the Southern Ocean lies one of South Africa’s most unique and ecologically valuable MPAs—the Prince Edward Islands Marine Protected Area, comprising the volcanic Marion Island and the smaller Prince Edward Island. Together, they represent South Africa’s only sub-Antarctic territory, rich in biodiversity and scientific significance. Declared in 2013, this MPA protects 30% of South Africa’s Southern Ocean territory, encompassing 80% of its marine ecosystem diversity. These waters are a haven for marine life—from krill and Patagonian toothfish to charismatic top predators like seals, seabirds, and killer whales.
Marion Island is more than just a rugged sub-Antarctic outpost—it is a living laboratory and sanctuary:
- Home to 40% of the world’s wandering albatrosses
- Teeming with millions of penguins, albatrosses, petrels, and seals
- Hosts unique benthic (seafloor) ecosystems found nowhere else in South Africa
- Provides essential feeding grounds for top predators
- A permanent weather station contributes vital data for monitoring climate change in the Southern Ocean
While the marine protections are robust, terrestrial threats persist. Invasive house mice, introduced in the 1800s, have devastated native invertebrates and seabird populations. The Mouse-Free Marion Project, aims to eradicate these invaders and restore the island’s fragile ecosystem. This year’s theme “Ocean Protection Needs Human Connection”—resonates deeply with the work being done at Marion Island. Scientists, conservationists, and policymakers must collaborate to protect this unique MPA. But the connection goes even deeper: through awareness, education, and support, every person has a role to play in safeguarding the ocean.
On MPA Day, we not only celebrate these protected places
we commit ourselves to ensuring they thrive for generations to come.

SANAP scientists have been conducting long-term ecological studies on albatross population trends, breeding behaviour, and foraging ecology, using tracking devices and direct observation to better understand how climate change, ocean dynamics, and human activities are impacting these vulnerable birds.
A major step in protecting Marion Island’s seabirds is the 
The Southern Ocean: A Climate Regulator: The Southern Ocean surrounding Antarctica is a house of climate regulation, absorbing vast amounts of atmospheric carbon and heat. SANAP researchers are actively researching ocean currents, sea ice dynamics, and carbon cycling to better understand how these processes are evolving in a warming world. (Photo credit: A Zietsman)
Protecting Life on the Edge: From the wandering albatross on Marion Island to microscopic extremophiles in Antarctic soils, life persists against all odds in these regions. SANAP’s biodiversity monitoring projects are uncovering the intricate web of life that depends on these environments — and how threats such as invasive species, plastic pollution, and climate variability are impacting these ecosystems.

Long-Term Science, Global Impact: With decades of data collection and continuous human presence at SANAP’s research stations, SANAP long-term research projects offer insights into environmental change. Through collaborations with international partners, SANAP helps shape global understanding of polar processes and their far-reaching effects. This World Environment Day, SANAP celebrates the resilience of our southernmost ecosystems and the SANAP community is dedicated to its preservation. As stewards of the Antarctic and sub-Antarctic, SANAP remain committed to advancing knowledge, promoting conservation, and ensuring these unique environments endure for future generations.

As South Africa’s gateway to the Southern Ocean and Antarctica, SANAP plays a vital role in environmental research and conservation in some of the planet’s most fragile and remote ecosystems — including Antarctica, Marion Island, and Gough Island. During Environment Month, SANAP takes pride in celebrating the unique natural heritage of these sub-Antarctic and Antarctic regions, where pristine ecosystems offer critical insight into global environmental changes.
The United Nations has designated May 22 as the International Day for Biological Diversity (IDB), a day to reflect on the vital role biodiversity plays in sustaining life on Earth. The 2025 theme, “Harmony with Nature and Sustainable Development,” underscores the importance of conserving biodiversity to ensure a sustainable future for both people and the planet. It is a timely reminder that a thriving natural world is the foundation of human well-being and a cornerstone for achieving the Sustainable Development Goals.
In South Africa, this day holds special meaning for the South African National Antarctic Programme (SANAP). Operating across three key research stations — Antarctica, Marion Island (part of the Prince Edward Islands), and Gough Island — SANAP plays a crucial role in understanding and preserving the unique biodiversity of the sub-Antarctic and Antarctic regions. These remote and fragile ecosystems are home to countless species, many of which are found nowhere else on Earth.
For decades, SANAP-supported scientists have been at the forefront of biodiversity research in these regions. Their work includes long-term monitoring of bird and marine mammal populations, studies on invasive species, climate change impacts, and ecosystem dynamics. Through rigorous field research and environmental stewardship, SANAP contributes to global knowledge and conservation efforts, ensuring these pristine environments continue to thrive for generations to come.
On this International Day for Biological Diversity, SANAP reaffirms its commitment to protecting the biodiversity of the Southern Ocean and its islands — not only for their intrinsic value but also for the essential role they play in the global ecosystem.
