"Start of on-station observations"

The R/V Mirai is now on station at north of the Palau Islands in the tropical western Pacific. In addition to continuous atmospheric and oceanic measurements such as surface meteorology, weather radars, ADCP, and so on, that those have been carried out since the beginning of the cruise, we've started to launch radiosonde and cast CTD every three hours.
Scientists, technical staff, and crew members on board are making a concerted effort for smooth operation. This photo shows CTD observation conducted at night. It started raining in the middle of the operation. I cannot help appreciating the observation data even more after watching closely people working so hard to obtain them!
