・Researchers' living quarters and principal researcher's apartment
For the purpose of teaching students and conducting surveys and research, university faculty and research institute staff (researchers) also board the Oshoro Maru. For convenience in conducting surveys and practical training, the quarters for such researchers (3 x 2-person cabins) are located on the same floor (aft deck) as the research compartments and observation deck. Each voyage also has a 「chief researcher」 on board as a leader who supervises the researchers and students. Since the chief researcher often goes up to the bridge as a coordinator and liaison between the ship and the crew, a single room for the chief researcher is located on the floor immediately below the bridge (end-boat deck). The chief scientist, who has the responsibility and authority to achieve the objectives of the voyage, is considered equal to or superior to the person in charge of the ship's operations, and his/her room is located alongside those of the captain and chief engineer.
The chief researcher's room is furnished with a bed, desk, locker, refrigerator, television, washstand, fan, and extension telephone. Researchers also use the bathroom and lavatory on the aft deck (both shared with the ship's crew).
