海洋渔业预报使用的遥感数据一般只能获得海洋表面的环境信息，而Argo数据可以为渔业预报提供较深处的温盐数据，为了在渔业预报中按其时间周期进行使用，需要计算它的周期以提高预报质量。通过功率谱估计计算出2001-2008年的数据存在的较长的周期为62．7天和117．5天，较短的周期为4．9天和9．8天，同时还有一个约为7天的不明显周期，观测剖面数据总量在年际与年内都存在较大变化。

The remote sensing data which are used by marine fishery forecast only can get the information of ocean surface, while Argo data can provide fishery forecast with temperature and saltinity data of deeper area. To use Argo data in cycle, we need to compute its circle to improve the quality of forecast. In 2001- 2008, the longer circle was 62.7 days and 117.5 days, and the shorter circle was 4.9 days and 9.8 days, which were obtained by power spectrum estimation. And there was an unobvious circle of 7 days. There existed big changes in observed profile data amount between years and within a year.
