Okhotsk Soya sea ice observation dataset in 2012

This dataset was obtained using PV Soya in the southern Sea of Okhotsk in February 2012, 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, winds, and longwave and shortwave radiation) 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_2012.docx.
