Water temperature, salinity, chlorophyll-a concentration, macro-nutrients (nitrate, nitrite, phosphate, and silicate), and zooplankton data were collected at six stations in various sea-ice environments: fast-ice, pack-ice, and ice-free open ocean. The use of an “ice-fence” protected observation equipment (e.g., plankton nets and CTDs) from damage due to sea-ice. This report provides the data obtained during the icebreaker Shirase cruise of the 60th Japanese Antarctic Research Expedition in the 2018/19 season, and is the third report for the marine ecosystem monitoring in the sea-ice region from the first report of the 2016/17 season in this journal.Polar Data Journal91132025-04National Institute of Polar Research2432-6771https://doi.org/10.17592/001.2024110517publisherhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=77&item_no=1&attribute_id=22&file_no=1CC BYhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=77&item_no=1&attribute_id=22&file_no=2Ⓒ 2025 National Institute of Polar Researchhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=77&item_no=1&attribute_id=22&file_no=3Ⓒ 2025 National Institute of Polar ResearchMarine biology2025-04-04
