Yoshiko-san, good job!

Ms. Yoshiko ISHIKAWA (Marine Works Japan) is a reliable and friendly marine technician. She is doing the nutrients analysis of water samplings from CTD and bucket. The nutrients are chemical compounds including P (phosphorus), N (nitrogen), Si (silicon) for growing phytoplankton. They cannot be measured by any electrical sensors and we need hand-operated procedures by marine technicians who have special skills for the analysis. In fact, Motesaku didn’t care of nutrients. After Yoshiko-san’s explanations, Motesaku understands the importance of the nutrients. Yoshiko-san, good job!
