| Research Abstract |
The mail target of the project is as follows.
1. The signals for climate and environments in the ice core.
The methods for scanning UV spectrometry was considered, which was probed to be rapid way to take the measurement for NO3. The preliminary data were obtained for the precipitation and sedimentation in the Arctic and antarctica.
2. The influence of sedimentary environments.
The local distribution of the matabolic process after deposition was investigated. The signals in the deposition between frost and snow differ each other.
3. The local distribution for the sedimentary flux
The local distribution for the sedimentary flux was estimated by the methods for ice core analyzes in Greenland and Antarctica. Some analyzes were process now.
