Okhotsk Soya sea ice observation dataset in 2000

This dataset was obtained using PV Soya in the southern Sea of Okhotsk in February 2000, in collaboration between Japan Coast Guard and Hokkaido University to monitor the ice conditions associated with the global warming and improve our understanding of sea ice processes. The dataset is composed of the meteorological data (surface air pressure, air temperature, vapor pressure, and winds) recorded on board at an interval of one minute, the ice thickness data measured with a video system, and hourly visual observation records conducted according to the international ASPeCt protocol. The data format is available in the file, named Readme_soya_2000.docx.本数据集由日本海上保安厅与北海道大学联合采集，于2000年2月在鄂霍次克海南部海域通过宗谷号（PV Soya）完成，旨在监测与全球变暖相关的海冰状况，并加深对海冰过程的科学认知。该数据集包含三类数据：一是以1分钟为间隔在船上记录的气象数据，涵盖地面气压、气温、水汽压与风速；二是采用视频系统测定的海冰厚度数据；三是依照国际ASPeCt协议（ASPeCt）开展的每小时目视观测记录。相关数据格式说明详见名为Readme_soya_2000.docx的文件。
