The Marine Botany Lab and Kagoshima City Aquarium participated in a research voyage aboard the T/S Nansei-Maru of Kagoshima University, conducting a deep subtidal algal survey off the coast of Tanegashima Island in the northern Ryukyu Islands. The weather and sea conditions were calm, and we successfully returned to Kagoshima today. This survey was conducted as part of a training voyage for university students in the Faculty of Fisheries.
