J-9 Drill Hole Temperatures

The Ross Ice Shelf Project (RISP) began in 1973, and lasted six field seasons. One of the primary goals for RISP was to drill a hole through the Ross Ice Shelf in order to study the ice, the ocean, and the ocean floor beneath the ice shelf. In late November 1974, during the second field season, the camp at J-9 (82.375S, 168.626W) was established, and this site was chosen for future deep core drilling. This datset records ice shelf and sub-ice shelf temperature profiles taken between 1974 and 1977 at the J9 drill site in The Ross Ice Shelf.

罗斯冰架项目（Ross Ice Shelf Project, RISP）于1973年启动，共开展6个野外作业季。该项目的核心目标之一是在罗斯冰架上钻取穿透性钻孔，以研究冰架本身、冰架下方的海洋及海底环境。1974年11月下旬，在第二个野外作业季期间，科研团队在J-9营地（南纬82.375°，西经168.626°）设立了野外站点，并选定该点位用于后续的深层冰芯钻探工作。本数据集记录了1974年至1977年间，在罗斯冰架J9钻探点位采集的冰架及冰架下温度剖面数据。
