- Chlorophyll a concentration is the most common indicator of phytoplankton biomass, basically regulated by macro-nutrients and light intensity. Therefore, long term monitoring of these parameters gives us fundamental information on ecosystem changes with climate changes. As part of the monitoring programs of the Japanese Antarctic Research Expedition (JARE), chlorophyll a concentration and macro-nutrients (nitrate, nitrite, phosphate and silicate) have been measured on board icebreakers Fuji and Shirase from JARE-14 in the 1972/73 season and from JARE-7 in the 1965/66 season, respectively. The same monitoring have also been conducted during the cruise of the training vessel (T/V) Umitaka-maru, Tokyo University of Marine Science and Technology since JARE-55 (2013/14). This report is the latest data determined during the T/V Umitaka-maru cruise in 2016/17 season.
