World Water Day 2026: Southern Ocean Science for a Water-Secure 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.
Postgraduate students in environmental and marine-related sciences are encouraged to apply for SEAmester IX – South Africa’s Class Afloat, taking place from 1–10 June 2026 aboard the country’s polar research vessel, the S.A. Agulhas II.
A Floating Classroom: The strength of SEAmester lies in its combination of theoretical learning and hands-on research at sea. Over the course of ten days, students participate in lectures from leading scientists while actively engaging in ship-based scientific work. The S.A. Agulhas II, a state-of-the-art research and polar supply vessel, provides the ideal teaching platform. Its onboard laboratories, research equipment and facilities allow students and lecturers to work closely together in an immersive scientific environment. Participants gain exposure to a wide range of marine science disciplines, including oceanography, marine biology, biogeochemistry and climate science. Daily lectures are paired with deck-based activities where students assist with research operations, collect data and learn how oceanographic instruments are deployed and analysed. Students also contribute to small scientific mini-projects, gaining practical research experience while working alongside specialist scientists.
Prepare a Strong Application: SEAmester is highly competitive, and applicants are encouraged to take time preparing their submissions. When applying, be sure to read the application requirements carefully and explain why you are a strong candidate. Demonstrate your interest in environmental or marine science and describe how the experience will contribute to your research and career goals. Write your application in your own words. The selection committee is looking for students who are motivated, curious and eager to engage in interdisciplinary research. SEAmester offers a rare opportunity to gain hands-on marine research experience while learning from leading scientists at sea. For postgraduate students interested in environmental change and ocean science, this programme provides an unforgettable introduction to research in the marine environment.
From December 2025 to February 2026, the South African National Antarctic Programme (SANAP) embarks on its annual takeover voyage to relieve and resupply SANAE IV in Queen Maud Land, Antarctica. This critical mission ensures a seamless transition between overwintering and incoming teams, sustaining South Africa’s year-round scientific presence in Antarctica. More than a logistical operation, the voyage represents a coordinated national effort — uniting government officials, scientists, aviation specialists, maritime crew, engineers, and support teams — all working together in one of the most demanding environments on Earth.
At the core of the transition are the Department of Forestry, Fisheries and the Environment (DFFE) takeover personnel, who oversee inspections, infrastructure assessments, compliance requirements, and environmental protocols at SANAE IV. Their work ensures that power generation, life-support systems, communications, and safety procedures remain fully operational for the year ahead. Supporting the operation from sea to ice is the skilled helicopter team from Ultimate Heli, who transport people and cargo between the vessel and the base with precision in narrow Antarctic weather windows.

The voyage south is safely guided by the Captain Roland Clutties and crew of the S.A. Agulhas II, whose expertise navigating the Southern Ocean and pack ice ensures the secure transport of passengers, fuel, equipment, and supplies. Onboard, the chefs and stewards keep teams energised with warm meals throughout the journey. Meanwhile, bulldozer operators and mechanics prepare for ice-shelf operations and CAT train traverses that will move bulk cargo inland to the station once the ship reaches the ice edge.

By early February 2026, the SANAP field campaign entered its final phase, completing measurements and preparing for extraction ahead of worsening weather.
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.
