Italian Icebreaker Laura Bassi Concludes 41st Antarctic Expedition Featuring Five Major Scientific Initiatives

On March 6, 2026, the Italian icebreaker Laura Bassi successfully concluded its 41st summer Antarctic campaign, marking the end of a rigorous four-month mission. The vessel returned to the port of Lyttelton, New Zealand, after navigating the challenging maritime conditions of the Ross Sea. This extensive scientific endeavor was conducted under the auspices of the National Antarctic Research Program (PNRA), which provides the necessary funding and framework for Italy's polar investigations.

The expeditionary force consisted of a diverse team of 44 technical and scientific experts, supported by a dedicated crew of 23 members. Throughout the four-month deployment, the team focused on five distinct research projects designed to deepen our understanding of the polar environment. These initiatives are part of a broader international effort to monitor the shifting dynamics of the Antarctic region and its influence on the global climate system.

Two primary research initiatives, MYSTERO and CSICLIC, took center stage during this mission. The MYSTERO project was dedicated to the exploration and mapping of submarine elevations across the continental shelf of the Ross Sea. Simultaneously, the CSICLIC project conducted a sophisticated analysis of carbon dioxide exchange within the bottom sediments of the Southern Ocean. This research is particularly vital given that the Southern Ocean is responsible for absorbing approximately 40% of the total carbon dioxide sequestered by the world's oceans.

The Laura Bassi serves as a cornerstone of Italian polar research and is managed by the National Institute of Oceanography and Applied Geophysics (OGS). As the only oceanographic research vessel owned by an Italian state institution, it boasts a robust construction certified as a PC5 class icebreaker under the Polar Code. With a displacement of 4,028 tons and a length of 80 meters, the ship provides a stable and capable platform for high-latitude scientific operations.

Data gathered during the 41st expedition will significantly enhance global climate models by providing insights into long-term carbon sequestration. The CSICLIC project's focus on seafloor sediments helps scientists understand processes that lock carbon away for hundreds or even thousands of years. This is a critical area of study, as the global ocean has absorbed more than 90% of the excess heat and 25% of the surplus carbon generated by human activities.

This latest success follows a history of notable achievements for the Laura Bassi in the Antarctic region. In January 2023, during the 38th PNRA expedition, the vessel set a world record by reaching the southernmost point ever recorded by a ship at 78° 44.280' South latitude in the Bay of Whales. The successful completion of the 2026 mission further solidifies Italy's strategic scientific presence and its ongoing commitment to polar exploration and environmental preservation.
