Oceanographic profile observations collected from station ITP-25 by Woods Hole Oceanographic Institution (WHOI) in the Arctic Ocean from 2008-09-22 to 2009-07-08 (NCEI Accession 0157149)

NCEI accession 0157149 contains in situ, physical and profile data from the ITP instrument ITP-25 in the Arctic Ocean from 2008-09-22 to 2009-07-08.

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.

美国国家环境信息中心（National Centers for Environmental Information, NCEI）存档编号0157149的数据集，包含2008年9月22日至2009年7月8日期间，北冰洋海域ITP-25型冰系剖面仪（Ice-Tethered Profiler, ITP）采集的原位物理海洋剖面数据。

冰系剖面仪系统由安装在浮冰顶部的小型表面舱组成，该舱支撑一条包裹塑料护套的钢丝绳系缆，系缆穿过浮冰延伸至海洋中，末端挂载重物以维持钢丝绳处于垂直状态。一台外形与尺寸类似Argo浮标（Argo float）的圆柱形水下仪器搭载于该系缆之上，可沿系缆垂直往复运动，搭载海洋学传感器遍历整个水层剖面。水体属性数据可通过遥测技术以近实时的方式从冰系剖面仪传输至岸基站点。

本数据集由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）的约翰·M·图尔（John M. Toole）采集，并作为冰系剖面仪项目的组成部分提交存档。
