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 fluxThe local distribution for the sedimentary flux was estimated by the methods for ice core analyzes in Greenland and Antarctica. Some analyzes were process now.

项目的邮件目标如下：1。冰芯中气候和环境的信号。研究了扫描紫外光谱法，探索了一种快速测定NO3的方法。获得了北极和南极地区降水和沉积的初步资料。沉积环境的影响。研究了沉积后代谢过程的局部分布。霜和雪之间的沉积信号彼此不同。沉积通量的局部分布用格陵兰和南极洲冰芯分析的方法估算了沉积通量的局部分布。一些分析正在进行中。
