KN189L04: WHOI cruise 189 leg 04 aboard the R/V Knorr from 2007-06-14 - 2007-07-15 (NODC Accession 0070540)

Post-cruise download of raw data from shipboard computer(s) as furnished by the Woods Hole Oceanographic Institution Shipboard Scientific Support Group and archived by the Marine Biological Laboratory Woods Hole Oceanographic Institution Library for the R/V Knorr - Cruise 189 Leg 04.

These data are part of a collection of ocean observation data from Woods Hole Oceanographic Institution ships OCEANUS (call sign WXAQ; built 1975.00; IMO 7603617), KNORR (call sign KCEJ; built 1970.00; IMO 7738618), and the ATLANTIS (call sign KAQP; built 1997.03; IMO 9105798). The data sets are the downloads of the shipboard computers after an individual cruise. As such, they contain basic raw and processed physical and meteorological data from the cruise. A data set may include XBT, CTD, and XCTD profiles, underway thermosalinograph and atmospheric measurements, gravity and magnetic field measurements, current measurements from ADCP, and still photographs from the Alvin submersible (Atlantis cruises only). Other data types (ROV, nutrients measured from bottle samples, etc.) and photographs documenting the cruise may be included.

本数据集为伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）船载科学支持小组提供的航次后原始数据下载包，由海洋生物实验室伍兹霍尔海洋研究所图书馆归档，对应研究船努纳号（R/V Knorr）第189航次第4航段。
本数据集隶属于伍兹霍尔海洋研究所旗下三艘研究船的海洋观测数据集合集，三船分别为：海洋号（OCEANUS，呼号WXAQ，1975年下水，IMO编号7603617）、努纳号（KNORR，呼号KCEJ，1970年下水，IMO编号7738618）以及亚特兰蒂斯号（ATLANTIS，呼号KAQP，1997年3月下水，IMO编号9105798）。本数据集为单航次结束后船载计算机的原始下载数据，包含本次航次采集的基础原始数据与经处理后的物理、气象观测数据，具体涵盖：抛弃式温深仪（Expendable Bathythermograph, XBT）、温盐深仪（Conductivity Temperature Depth, CTD）及抛弃式温盐深仪（Expendable Conductivity Temperature Depth, XCTD）剖面数据，走航式温盐监测仪与大气观测数据，重力与磁场测量数据，声学多普勒海流剖面仪（Acoustic Doppler Current Profiler, ADCP）采集的海流数据，以及仅在亚特兰蒂斯号航次中获取的阿尔文潜水器（Alvin submersible）静态影像资料。数据集亦可能包含其他类型数据，例如水下遥控潜水器（Remotely Operated Vehicle, ROV）数据、瓶装水样测定的营养盐数据等，以及用于记录本次航次的各类影像资料。
