On 8 June, the global community celebrates World Oceans Day, recognising the critical role oceans play in sustaining life on Earth. Oceans regulate climate, produce much of the oxygen we breathe, absorb carbon dioxide, support biodiversity, and provide food and livelihoods for billions of people. This year’s observance highlights the importance of protecting ocean ecosystems and ensuring their resilience in the face of environmental change.
World Oceans Day theme for 2026 is “Reimagine: Beyond the world we know, a new relationship with our ocean,” with a primary conservation action theme focused on “Strong Marine Protected Areas for Our Blue Planet”
The Southern Ocean, which surrounds Antarctica, is one of the most important yet least understood oceans on Earth. It connects the Atlantic, Indian and Pacific Oceans and plays a vital role in regulating global climate by absorbing heat and carbon dioxide from the atmosphere. Changes in the Southern Ocean can influence weather patterns, sea levels, marine ecosystems and climate processes far beyond the polar regions, including those affecting South Africa.
SANAP scientists are at the forefront of Southern Ocean research. Projects such as The Biological Carbon Pump in a Changing Southern Ocean, Micronutrient and Pollutant Trace Elements at the Air-Sea Interface of the Southern Ocean, Decoding the Mercury Cycle in the Southern Ocean, and Southern Ocean Carbon-Heat Nexus investigate the complex processes that influence ocean health and climate regulation. Research on phytoplankton through the ECOSOPHY project helps scientists understand the foundation of Southern Ocean food webs and the ocean’s ability to absorb carbon from the atmosphere.
World Oceans Day reminds us that protecting the ocean begins with understanding it. Through long-term observations, innovative technologies and international collaboration, SANAP continues to generate knowledge that contributes to the sustainable management of one of the planet’s most important ecosystems. As we continue to celebrate Environment Month, we recognise that a healthy Southern Ocean is essential for a healthy planet.

On 22 May each year, the world celebrates the International Day for Biological Diversity (IDB), commemorating the adoption of the Convention on Biological Diversity (CBD). The day serves as an important reminder that biodiversity underpins all life on Earth — yet it is being lost at an unprecedented rate. The 2026 theme, “Acting locally for global impact,” highlights how local conservation efforts contribute meaningfully to global biodiversity goals. This message resonates strongly with South Africa and the work undertaken through the South African National Antarctic Programme (SANAP).
South Africa’s research and conservation efforts in Antarctica, the Prince Edward Islands and Gough Island provide critical insights into some of the world’s most unique and fragile ecosystems. These remote environments host extraordinary biodiversity, ranging from microscopic marine organisms to globally significant seabird and marine mammal populations.
The Prince Edward Islands — consisting of Marion Island and Prince Edward Island — are internationally recognised for their rich biodiversity and high conservation value. The islands support vast colonies of albatrosses, petrels, penguins and seals, many of which depend on the Southern Ocean ecosystem for survival. Gough Island, another globally important sub-Antarctic ecosystem where South African scientists contribute to research and conservation collaborations, is renowned for its exceptional seabird diversity and World Heritage status.
Through SANAP, South African researchers conduct long-term monitoring and cutting-edge scientific studies that improve understanding of biodiversity, ecosystem functioning and the impacts of climate change in these regions. Research focuses on areas such as marine ecology, conservation biology, invasive species management and ocean-atmosphere interactions. This work contributes not only to local conservation management, but also to international biodiversity and climate science initiatives.
South Africa’s hosting of the International Day for Biological Diversity 2026 Global Flagship Event marks a historic milestone. As one of the world’s megadiverse countries, South Africa continues to demonstrate how science, conservation and community-led stewardship can help halt and reverse biodiversity loss.
The work undertaken through SANAP reflects the spirit of this year’s theme: local scientific action in remote Southern Ocean and Antarctic regions contributes to global understanding, policy development and biodiversity conservation for future generations. As we mark IDB 2026, SANAP celebrates the scientists, conservationists and support teams working to protect the biodiversity of Antarctica and the sub-Antarctic islands — ecosystems that remain vital to the health of our planet.

Macaroni Penguin: The Macaroni penguin is one of the most abundant penguin species studied within SANAP-supported regions, including Marion Island. Recognisable by its striking yellow-orange crest, this species forms vast breeding colonies that can number in the millions, offering researchers unique opportunities to study population dynamics and ecosystem interactions. Feeding primarily on krill and small marine organisms, macaroni penguins are also impressive divers, capable of reaching depths of up to 100 metres. SANAP researchers monitor their breeding success and foraging behaviour to better understand the health of subantarctic marine ecosystems.
Emperor Penguin: The Emperor penguin, the largest of all penguin species, is a true symbol of Antarctic resilience. Although primarily found on mainland Antarctica rather than Marion or Gough Island, SANAP-affiliated research contributes to broader Antarctic ecosystem studies that include this iconic species. Adapted to survive extreme temperatures as low as −60°C, emperor penguins exhibit remarkable breeding behaviour, with males incubating eggs on their feet during the harsh winter months. Their ability to dive to depths exceeding 500 metres continues to fascinate scientists studying physiological adaptation and survival in extreme environments.
King Penguin: The King penguin is a prominent feature of Marion Island’s wildlife and a key focus of SANAP research. With their distinctive orange neck patches and large body size, king penguins form dense breeding colonies that provide valuable data on population trends and climate variability. Notably, they have the longest breeding cycle of any penguin species, lasting over a year, which makes them particularly sensitive to environmental changes. Researchers on Marion Island closely track their foraging patterns and breeding success to assess shifts in ocean conditions and prey availability.
Rockhopper Penguin:The Rockhopper penguin, known for its energetic movements and spiky yellow crest, is a charismatic species found on Marion Island and other subantarctic locations. Its name comes from its habit of hopping across rocky terrain, often breeding on steep slopes that challenge both the birds and the researchers studying them. SANAP teams monitor their populations closely, as rockhopper penguins are considered vulnerable to environmental pressures. Their diet of krill, squid, and crustaceans links them directly to ocean health, making them important indicators in marine research.
Adélie Penguin: The Adélie penguin is a classic Antarctic species commonly found along the icy coastline. While not resident on Marion or Gough Island, it remains an important part of SANAP’s broader Antarctic research scope. Easily identified by the white ring around its eye, the Adélie penguin builds pebble nests on rocky ground and relies heavily on krill as a food source. Long-term monitoring of Adélie populations helps scientists understand the impacts of sea ice changes and climate variability on Antarctic ecosystems.
The accompanying infographic can also serve as a useful educational tool for learners, helping children engage with these remarkable species in their school projects.

For the South African National Antarctic Programme (SANAP), the Southern Ocean plays a critical role in understanding Earth’s water systems. This vast and dynamic ocean regulates global climate, drives ocean circulation and influences rainfall patterns far beyond the polar regions—including across southern Africa. SANAP-supported research in this remote environment helps scientists track how changing temperatures, melting ice and shifting currents affect the global water cycle. By studying these processes, researchers gain insights into future water availability, the stability of marine ecosystems and the long-term impacts of climate change on freshwater resources.
Protecting water for future generations depends on knowledge, collaboration and sustained scientific effort. Research conducted in the Southern Ocean not only deepens our understanding of planetary systems, but also supports informed decision-making that benefits societies worldwide. As we mark World Water Day 2026, SANAP’s work highlights a powerful truth: even the most distant oceans are connected to the water we rely on every day. By investing in science and fostering inclusive approaches to water management, we can help ensure that where water flows, opportunity and equality can grow.
