PROBLEM TO BE SOLVED: To provide an ice sheet management system and an ice sheet management method capable of always maintaining an ice sheet in an appropriate state.SOLUTION: An ice sheet management system includes: a brine cooler 16 cooling a cooling medium; a cooling pipe 12 that is arranged on a bottom of an ice sheet 18 and in which the cooling medium flows; a flow volume adjustment unit 14 that can adjust a flow volume of the cooling medium flowing to the cooling pipe 12; and a controller 24. The controller 24 controls the flow volume adjustment unit 14 so that a heat quantity of cold flowing from the cooling pipe 12 in the ice sheet 18 can match a heat quantity of cold flowing from a surface layer portion of the ice sheet 18 out into the atmosphere. 【課題】氷床を常に適切な状態に維持できる氷床温度管理システム及び氷床温度管理方法を提供する。【解決手段】氷床温度管理システムは、冷却媒体を冷却するブラインクーラー１６と、氷床１８の底部に配置されて冷却媒体が通流する冷却配管１２と、冷却配管１２に流れる冷却媒体の流量を調整可能な流量調整部１４と、制御装置２４とを有する。制御装置２４は、冷却配管１２から氷床１８に流入する冷熱の熱量と氷床１８の表層部から大気中に流出する冷熱の熱量とが一致するように、流量調整部１４を制御する。【選択図】図１
