Oceanographic profile observations collected from station ITP-74 by Woods Hole Oceanographic Institution (WHOI) in the Arctic Ocean from 2013-09-07 to 2014-08-30 (NCEI Accession 0157193)

NCEI accession 0157193 contains in situ, physical and profile data from the ITP instrument ITP-74 in the Arctic Ocean from 2013-09-07 to 2014-08-30.

The Ice-Tethered Profiler (ITP) system consists of a small surface capsule that sits atop an ice floe and supports a plastic-jacketed wire rope tether that extends through the ice and down into the ocean, ending with a weight (intended to keep the wire vertical). A cylindrical underwater instrument (in shape and size much like an Argo float) mounts on this tether and cycles vertically along it, carrying oceanographic sensors through the water column. Water property data are telemetered from the ITP to shore in near-real time.

These data were collected by John M. Toole of Woods Hole Oceanographic Institution, and submitted as part of the ITP project.

NCEI入藏编号0157193包含2013年9月7日至2014年8月30日期间，北冰洋内ITP-74仪器的原位物理与剖面观测数据。

冰系留剖面仪（Ice-Tethered Profiler，ITP）系统由安装于浮冰顶部的小型水面舱组成，该舱支撑一根包覆塑料护套的钢丝绳系缆，系缆穿过浮冰延伸至海洋深处，末端配有配重（用于保持系缆垂直状态）。一台外形与尺寸均与Argo浮标高度相似的圆柱形水下仪器挂载于该系缆之上，可沿系缆垂直往复运动，搭载海洋学传感器在水柱中完成数据采集。水体属性数据可通过近实时遥传方式从ITP传送至岸基站点。

本数据集由伍兹霍尔海洋研究所的约翰·M·图尔（John M. Toole）采集，并作为冰系留剖面仪项目的一部分提交。
