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.

Every year on 3 March, the world celebrates World Wildlife Day, recognising the extraordinary diversity of life and the need to conserve it. For South Africa, this commitment extends far beyond the mainland — to the remote sub-Antarctic and Antarctic regions where SANAP conducts research and conservation work and plays a vital role in understanding and protecting some of the world’s most unique ecosystems.

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.

Through science, conservation management, and responsible environmental practices, SANAP continues to protect these extraordinary environments for future generations. On this World Wildlife Day, we reaffirm our commitment to understanding, conserving, and championing life at the edge of the Earth. We celebrate the resilience of life in extreme environments, the dedication of researchers working in extreme conditions and South Africa’s role in polar science and environmental stewardship.

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.

Monitoring Antarctic Ice Shelf Stability. Antarctic ice shelves play a critical role in controlling future sea-level rise.
In January 2026, an international research team began the second field campaign of Structural Glaciological Analysis of the Antarctic Ice Shelves, supported by the National Research Foundation and the South African National Antarctic Programme (SANAP). Led by the University of Cape Town’s Polar Engineering Research Group, the project combines expertise in engineering, geophysics, and glaciology.
The focus is the western Fimbulisen Ice Shelf , which regulates ice flow from the Antarctic interior into the Southern Ocean via the Jutulstraumen Glacier. Changes in its stability directly affect ice discharge and global sea level.
The SANAP 2025/2026 team arrived aboard SA Agulhas II on 11 January 2026 and established a field camp on the ice shelf. Early work centred on retrieving data from permanent GNSS stations and phase-sensitive radar instruments measuring ice motion, thickness, and basal melt.
These efforts marked the start of five intensive weeks of fieldwork aimed at understanding how Antarctic ice shelves respond to a warming climate.
