The strictest in Japan is probably the manner of Marine Works, which is responsible for observation work on JAMSTEC research vessels. (They strictly follow international standards.)
First, the Niskin water sampler is checked for leaks one by one before starting the water sampling process. The water sampler shouts, "Niskin No. 12, no leak!", and the supervisor repeat "No. 12, no leak!", and records. If the water sampler shouts "Bottle number 11, water temperature 1.2!", the supervisor will repeat and record the same.
(Many of your manners are to ensure your safety on board, so make sure you follow them.)
By the way, I (Ooki) don't seem to have the "experienced look" of an oceanographer, even to myself. (As might be expected, I would look like a veteran on a training voyage with students who are complete beginners, but...) Despite the considerable number of times I have conducted oceanographic observations. Mr. K of the Tohoku National Fisheries Research Institute (≠Hokkaido University Fisheries Sciences) said the same thing. I was on board the other day with Mr. K, and we both looked at each other and were convinced. I tend to wander around on vessels and make a lot of unnecessary movements, and when there is someone else I can rely on, I tend to rely on him or her. On the other hand, the oceanographers from Hokkaido University Fisheries Sciences were very familiar with oceanographic observation. Even the graduate students of Hokkaido University Fisheries Sciences are veterans. My goal is to nurture such dependable veteran oceanographers, and I myself would like to take it easy shipboard observation for a long time. Best regards, everyone.
