| Research Abstract |
In this project study , the following three researches were carried out . Almost the studies were undertaken at the short period because considerable phenomena related to environmental change in Antarctic region were detected during the austral spring to summer . The observation , analyses of the date and materials , and discussion at workshops were timely performed and they produced lots of fruitful results .
(1) Environmental change in atmosphere and magnetosphere
Plasma current in magnetosphere was surveyed using HF radar and imaging riometer as well as in mesosphere and thermosphere , and significance and importance of long-term observation in the aurora conjugating zone in the Arctic was confirmed .
(2) Environmental change in atmo-hydrosphere and lithosphere
Data on the relationships between periglacial phenomena and Cenozoic era were comparatively analyzed . In order to establish the date of the rocks at the Sorrondane mountain region , the rock samples are analyzed by mass spectrometer (Ion microprobe) .
(3) Marine environmental change in Southern Ocean
The possibility of the middle- and long-term observation in the Indian sector in the Southern Ocean was surveyed and the date were analyzed . The present status of international collaborative study , and date bank and marine resources was surveyed .
