The group's main purpose of existence is to collect large volume (250 liters) seawater samples in a range of depths - from 10 meters to the ocean bottom (~5500m) using the model N12-1000 large volume water sampler. To the right are pictures of how people gather all their strength to move the 1 ton sampler. Ha! Of course they enjoy the help of those all-powerful mechanical winches.
Now the hard part comes in transferring all those seawater to your own 250 liter buckets. They use pumps. The pictures show Nagai-sensei with his beloved samples already in those sturdy buckets. Yehey!
