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.

Earth Day is commemorated annually on 22 April and is one of the largest global environmental movements. In 2026, the theme “Our Power, Our Planet” highlights the importance of civic action, community engagement, and collective responsibility in addressing environmental challenges. For the South African National Antarctic Programme (SANAP), Earth Day is not only a moment of reflection, but also a celebration of ongoing scientific research, conservation efforts, and the people who make this work possible.
Why Earth Day Matters! SANAP’s vision to understand, develop, and conserve the Antarctic, sub-Antarctic, and Southern Ocean environments aligns directly with the principles of Earth Day. These remote regions are critical to the health of our planet. They regulate global climate systems, support unique biodiversity, and provide essential insights into environmental change. Research is vital in a world where environmental risks continue to dominate global concerns and research conducted through SANAP contributes to:
- Understanding climate change and its global impacts
- Protecting fragile sub-Antarctic ecosystems
- Monitoring marine and terrestrial biodiversity
- Supporting sustainable environmental stewardship
SANAP scientists and researchers work in some of the most extreme environments on Earth, studying ocean systems, atmospheric processes, wildlife ecology, and environmental change. Their work contributes to international scientific knowledge and informs global responses to climate challenges. Equally important are the support personnel who ensures that research can be conducted safely and effectively. Earth Day is an opportunity to recognise the collective effort required to sustain Antarctic science.
Earth Day reminds us that protecting the environment is a shared responsibility. While SANAP operates in remote regions, the insights gained have global relevance. Healthy ecosystems—from the Antarctic to Southern Ocean currents—play a crucial role in climate regulation, biodiversity, and human wellbeing. The 2026 focus on civic mobilisation and community action reinforces the idea that meaningful change comes from both scientific understanding and public engagement. Within the SANAP community, Earth Day is a time to:
- Reflect on the importance of Antarctic and ocean research
- Celebrate the contributions of scientists and support teams
- Promote awareness of environmental conservation
- Inspire continued commitment to protecting our planet
By advancing knowledge and supporting conservation, SANAP contributes to a global effort to safeguard Earth’s future.

Each year on World Water Day (22 March), the global community reflects on the importance of freshwater and the urgent need to protect it. In 2026, the theme “Water and Gender: Where water flows, equality grows” reminds us that access to clean water is not only an environmental priority, but also a social one. Around the world, water scarcity, pollution and climate change continue to threaten communities and ecosystems alike. Through initiatives led by UNESCO—including the Intergovernmental Hydrological Programme (IHP) and the World Water Assessment Programme (WWAP)—scientific research is being translated into real-world solutions that help countries better manage and safeguard this vital resource.

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.

Guardians of the Sub-Antarctic: The Prince Edward Islands — comprising Marion Island and Prince Edward Island — are globally significant biodiversity hotspots, they host thriving populations of seabirds and marine mammals, including King, Macaroni, Gentoo, and Rockhopper penguins, several Albatross and Petrel species, Southern Elephant seals and Antarctic Fur seals and Killer whales. SANAP-supported researchers monitor wildlife populations to detect changes linked to climate variability, ocean conditions, and human impacts. Long-term datasets collected over decades allow scientists to track breeding success, foraging behaviour, migration patterns, and survival rates.
These islands are also a Special Nature Reserve — South Africa’s highest level of environmental protection — ensuring strict conservation management. Ongoing efforts include the monitoring ecosystem health, studying predator-prey relationships, investigate the effects of climate change on sub-Antarctic food webs and managing invasive species. The eradication of invasive species and strict biosecurity controls are among conservation projects that protect these fragile ecosystems from human-introduced threats.

The End: From Field Data to Global Impact
By early February 2026, the SANAP field campaign entered its final phase, completing measurements and preparing for extraction ahead of worsening weather.
Temporary GNSS stations along the calving front were recovered, allowing detailed mapping of ice velocities across the ice shelf. Advanced radar surveys also measured ice thickness and internal crystal orientation, improving models of ice flow and fracture behaviour.
Seismic equipment was retrieved after weeks of recording, capturing data on both controlled signals and natural fracture events. These datasets will support detailed imaging of ice-shelf structure and zones of weakness.
As severe weather approached, the team secured equipment, dismantled installations, and restored the camp site, marking the successful completion of a productive campaign.
The project’s findings will improve predictions of Antarctic ice loss and future sea-level rise, with implications for global climate systems, coastal communities, and ecosystems. As fieldwork ends, long-term data analysis begins.

The Duration: Life and Science on the Fimbulisen Ice Shelf
Through mid- and late January, the team balanced demanding science with the realities of Antarctic fieldwork. GNSS stations positioned around major basal crevasses provided precise measurements of ice motion and fracture growth, helping assess the risk of large calving events. Complementary radar surveys quantified changes in ice thickness, supplying key inputs for ice-shelf flow models.
Seismic surveys used arrays of geophones and controlled energy sources to image the ice shelf and the ice–ocean interface. Drone-based ground-penetrating radar revealed the structure and evolution of deep basal crevasses, building on data from the previous season.
Fieldwork was frequently interrupted by severe storms, including wind gusts exceeding 120 km/h. Despite delays, the team adapted schedules and used downtime for maintenance and data checks. A major milestone was the first deployment of SAR corner reflectors on an Antarctic ice shelf, enabling highly accurate satellite tracking of ice motion.
Together, these measurements produced a unique dataset capturing both surface and subsurface behaviour of the Fimbulisen Ice Shelf.
