Marine ecosystem monitoring in the sea-ice region of Lutzow-Holm Bay, off Syowa Station, during the icebreaker Shirase cruise of the 59th Japanese Antarctic Research Expedition

As part of the monitoring program of the Japanese Antarctic Research Expedition (JARE), marine ecological monitoring in the sea-ice region of Lutzow-Holm Bay, off Syowa Station, has been routinely carried out since JARE-52 (2010/11 season) to investigate biological production and mechanisms in relation to sea-ice. 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.作为日本南极考察队（Japanese Antarctic Research Expedition，简称JARE）监测计划的组成部分，自第52次日本南极考察（JARE-52，2010/11考察季）起，团队便针对昭和基地周边吕佐夫-霍尔姆湾的海冰区域开展常规海洋生态监测，以探究与海冰相关的生物生产过程及其内在机制。本次监测在覆盖固定冰、流冰群及无冰开阔大洋等多种海冰环境的6个站位采集数据，涵盖水温、盐度、叶绿素a浓度、大量营养素（硝酸盐、亚硝酸盐、磷酸盐与硅酸盐）以及浮游动物相关信息。本次监测通过布设“冰障（ice-fence）”装置，保护浮游生物网、温盐深仪（CTD）等观测设备免受海冰损坏。
