Oceanographic profile observations collected from station ITP-7 by Woods Hole Oceanographic Institution (WHOI) in the Arctic Ocean from 2007-04-28 to 2007-11-01 (NCEI Accession 0157189)

NCEI accession 0157189 contains in situ, physical and profile data from the ITP instrument ITP-7 in the Arctic Ocean from 2007-04-28 to 2007-11-01.

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 存档编号0157189 包含了2007年4月28日至2007年11月1日期间，北极海域内ITP-7型冰系剖面浮标（Ice-Tethered Profiler, ITP）仪器的原位物理特性与剖面观测数据。

冰系剖面浮标（Ice-Tethered Profiler, ITP）系统由安装于浮冰顶部的小型表面舱体构成，该舱体承载一条包裹塑料护套的钢丝绳系缆，该系缆穿过浮冰并向下延伸至海洋，末端配有配重（用于维持系缆竖直状态）。圆柱形水下观测仪器（外形与尺寸与Argo浮标高度相似）安装于该系缆之上，可沿系缆做垂直往复运动，搭载海洋学传感器在水柱中完成观测。水体参数数据通过该浮标以近实时方式遥传至岸基站点。

该批数据由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）的约翰·M·图尔采集，并作为ITP项目的组成部分提交归档。
