澳大利亚联邦科学与工业研究组织与美国Saildrone公司合作，部署了一艘7米长的自主无人船，开始绕南极航行以收集气候科学数据1。该无人船计划航程约22,000公里，预计耗时7至9个月完成1。此次任务旨在采集海洋和大气中的关键信息，帮助科学家深入理解海洋在全球变暖中的作用1。
无人船将在极端恶劣的环境中运行，预计将面临8米高的波浪和35节的风速1。它将收集包括风速、大气压力、太阳辐射、海温、盐度、叶绿素及二氧化碳水平在内的多项数据1。研究人员指出，海洋每年吸收约三分之一的人为碳排放1，每吨化石燃料燃烧释放的二氧化碳中，约500公斤被海洋和森林吸收1。
该项目规模更为宏大——合作双方计划部署四艘无人船，每隔三个月发射一艘，覆盖南冰洋、太平洋、大西洋和印度洋1。
Australia's CSIRO research organization and U.S.-based Saildrone have deployed a seven-meter autonomous vessel to circumnavigate Antarctica and collect critical data on ocean and atmospheric carbon dioxide levels 1. The robotic ship is expected to complete the approximately 22,000-kilometer journey in seven to nine months, departing from Hobart and passing through Drake Strait and around South Africa 1.
During its voyage, the vessel will encounter formidable conditions, including waves reaching eight meters high and wind speeds of up to 35 knots 1. Despite these challenges, the craft will gather comprehensive measurements including wind speed, atmospheric pressure, solar radiation, sea temperature, salinity, chlorophyll levels, and carbon dioxide concentrations 1. According to researchers, the ocean absorbs roughly one-third of anthropogenic carbon emissions annually 1, with approximately 500 kilograms of carbon dioxide from every ton of burned fossil fuel being absorbed by oceans and forests 1.
This deployment is part of a broader initiative to position four autonomous vessels over time, with new ships launching every three months to provide continuous coverage across the Southern Ocean, Pacific, Atlantic, and Indian Oceans 1. The mission aims to enhance scientific understanding of the ocean's role in global warming through systematic environmental monitoring in one of Earth's most remote and extreme regions.
