Next Antarctic summer, NORSAR will install new, advanced measurement instruments—the southernmost instruments on solid rock. These devices will provide valuable insights into the structure of the Earth's crust, ice movements, and atmospheric dynamics.

Antarctica and the Southern Ocean are key drivers of the Earth's oceanic and atmospheric systems. Processes occurring at the southern end of the globe impact the entire planet, and melting ice can lead to dramatic increases in global sea levels.

Plans for a new research station and infrastructure will allow Norway to continue its longstanding polar research tradition and contribute to global scientific efforts. NORSAR is part of the Norwegian team that, through the Troll Observatory Network (TONe) project, aims to deliver new research infrastructure in Queen Maud Land.

Since 2012, NORSAR has operated a single seismometer, known as "Lille Trille," in Queen Maud Land. Now, additional instruments will be installed in an array formation, providing more accurate data on ice movements and seismic activity, including earthquakes. A separate array for atmospheric sound measurement, known as infrasound, will also be installed, offering valuable data for weather and climate models.

Optimal Site for High-Quality Measurements

To achieve precise measurements, it is essential to place instruments in areas with minimal background noise. The Norwegian government is evaluating the construction of a new research station in Queen Maud Land, with a directive for renewable energy solutions like wind turbines. Since NORSAR’s instruments are highly sensitive and wind turbines generate ground vibrations, a new site, Armlenet—11 km from the Troll station—is being inspected. NORSAR believes this is a suitable area for high-quality measurements. While being outside the established power grid is a challenge, NORSAR has extensive experience with off-grid operations in Svalbard's demanding climate and is well-prepared for the task. The observatory will be made autonomous to minimize the need for maintenance.

Equipment has already arrived in Antarctica, and logistics are on track to begin data collection in spring 2026. The infrastructure is part of the TONe project, led by the Norwegian Polar Institute and funded by the Norwegian Research Council. The TONe project is a significant national investment that will create unique opportunities for Norwegian and international research.
