科学家们发明了一种新的仪器来作为研究被几千米厚的冰层覆盖的南极大陆及其周围海底地质结构的工具。最近，在波士顿召开的一次美国国家地理学会的会议上，一个国际小组首次展示了一幅有关南极大陆及其周围海底详细的地磁变化图。这幅图是南极地磁场异常数据收集计划项目的一? Scientists invented a new instrument as a tool to study the submarine geological structure of the Antarctic continent and its surrounding area covered by a few kilometers thick ice. Recently, at a meeting of the National Geographic Society in Boston, an international team presented for the first time a detailed map of geomagnetic variation on the seabed of the Antarctic continent and its surroundings. This map is one of the Antarctic Geomagnetic Anomaly Data Collection Project.
