The collection of micrometeorites in the Yamato Meteorite Ice Field of Antarctica in 1998
In austral summer season of 1998,we collected micrometeorites at the Meteorite Ice Field around the Yamato Mountains, Antarctica. It was the first attempt to collect micrometeorites at inland bare ice in Antarctica and to use a filter with 10μm openings; it can capture particles that overlap in size...
