Chlorophyll a and macronutrient concentrations during the icebreaker Shirase cruise of the 60th Japanese Antarctic Research ExpeditionengSouthern Oceanchlorophyll amacro-nutrientshttp://id.nii.ac.jp/1434/00000025/info:doi/10.20575/00000025Journal ArticleChlorophyll a concentration is the most common indicator of phytoplankton biomass, basically regulated by physico-chemical properties such as temperature, salinity, macronutrients and light intensity. As part of the monitoring programs of the Japanese Antarctic Research Expedition (JARE), water temperature, salinity, chlorophyll a concentration, and macronutrients (nitrate, nitrite, phosphate, and silicic acid) have been determined since 1965. This report presents the latest data collected during the Shirase cruise in the 2018–2019 season.Polar Data Journal547532021-03National Institute of Polar Research2432-6771https://doi.org/10.17592/001.2020070705publisherhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=39&item_no=1&attribute_id=22&file_no=1CC BYhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=39&item_no=1&attribute_id=22&file_no=2© 2021 National Institute of Polar Researchhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=39&item_no=1&attribute_id=22&file_no=3© 2021 National Institute of Polar ResearchMarine biology2021-03-17
