日本の調査船「海陽丸」による2018/19シーズンの南洋東インド区(80?150°E)における学際的生態系調査
A multidisciplinary ecosystem survey in the eastern Indian sector of the Southern Ocean (80?150°E) during 2018/19 season by the Japanese survey vessel, Kaiyo-maru
Progress in Oceanography Last update 10 March 2025
The large-scale multidisciplinary ecosystem survey in the eastern Indian sector (80-150°E) of the Southern Ocean was conducted by the Japanese research vessel, Kaiyo-maru, during the 2018-2019 austral summer (KY1804 survey). This was the first time such a large-scale survey had been conducted in the area since 1996. The survey was conducted with two main objectives: (1) estimation of standing stock (biomass) of Antarctic krill in the survey area and (2) oceanographic observations in the area to detect any long-term changes. Along with these main objectives, we attempted to detect changes in the marine ecosystem between 1996 and 2018–2019 by conducting a survey covering from primary producers to top predators. The results of the survey are compiled in this special issue.
