AT004L04: WHOI cruise 004 leg 04 aboard the R/V Atlantis from 2001-03-04 - 2001-03-31 (NODC Accession 0055300)

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 Atlantis - Cruise 004 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R/V亚特兰蒂斯号（R/V Atlantis）004航次第4航段的船载计算机原始数据航后下载包，由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）船载科学支持小组提供，并由伍兹霍尔海洋研究所海洋生物实验室图书馆归档。

本数据集隶属于伍兹霍尔海洋研究所旗下三艘科考船的海洋观测数据集合集，三船分别为：欧申纳斯号（OCEANUS，呼号WXAQ，1975年建造，IMO编号7603617）、诺尔号（KNORR，呼号KCEJ，1970年建造，IMO编号7738618）以及亚特兰蒂斯号（ATLANTIS，呼号KAQP，1997年3月建造，IMO编号9105798）。此类数据集为单航次结束后船载计算机的下载数据包，包含本航次的基础原始与处理后物理、气象观测数据。单份数据集可包含抛投式温盐深剖面仪（Expendable Bathythermograph, XBT）、温盐深剖面仪（Conductivity-Temperature-Depth, CTD）、可抛式温盐深剖面仪（Expendable Conductivity-Temperature-Depth, XCTD）剖面数据，走航式温盐廓线仪（underway thermosalinograph）与大气观测数据，重力与磁场测量数据、声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）海流测量数据，以及仅在亚特兰蒂斯号航次中搭载的阿尔文深潜器（Alvin submersible）静态影像资料。此外，数据集还可包含其他类型数据（如遥控水下机器人（Remotely Operated Vehicle, ROV）作业数据、瓶采样品营养盐检测数据等）以及航次纪实影像资料。
