SALINITY, HYDROSTATIC PRESSURE, SIGMA-THETA, FLUORESCENCE and other profile data collected in the Gulf of Guinea, Mediterranean Sea - Western Basin and others on the ALBATROSS IV, ENDEAVOR and other platforms cruises AL9306, AL9403II and others as part of the GB project from 1993-05-22 to 1997-05-1

NODC Accession 0107210 includes profile, biological and physical data collected aboard the ALBATROSS IV, ENDEAVOR, OCEANUS and SEWARD JOHNSON during cruises AL9306, AL9403II, EN268, OC301, OC303, SJ9503, SJ9505 and SJ9507 in the Gulf of Guinea, Mediterranean Sea - Western Basin, North Atlantic Ocean, North Pacific Ocean and Tyrrhenian Sea from 1993-05-22 to 1997-05-17. These data include SALINITY, HYDROSTATIC PRESSURE, SIGMA-THETA, FLUORESCENCE, Potential temperature (theta) and TRANSMISSIVITY. The instruments used to collect these data include CTD. These data were collected by Greg Lough and James P. Manning of National Marine Fisheries Service and Steve M. Bollens of Washington State University as part of GB. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-04-26.

The following is the text of the abstract provided by BCO-DMO:

The MOCNESS is based on the Tucker Trawl principle (Tucker, 1951). The particular MOCNESS system from which these CTD data came is one of three net systems. The MOCNESS-.25 carries nine rectangular nets (1/4-m2), usually with 64 micrometer mesh. In all three MOCNESS systems, the underwater unit sends a data frame, comprised of temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds. Temperature (to approximately 0.01 deg C) and conductivity are measured with SEABIRD sensors. Normally, a modified T.S.K.-flowmeter is used. Both the temperature and conductivity sensors and the flowmeter are mounted on top of the frame so that they face horizontally when the frame is at a towing angle of 45deg. Calculations of salinity (to approximately 0.01 o/oo S), potential temperature (theta), potential density (sigma), the oblique and vertical velocities of the net, and the approximate volume filtered by each net are made after each string of data has been received by the computer. (Wiebe et al., 1985) In addition, data were collected from four other sensors attached to the frame: the Transmissometer, the Fluorometer, the Downwelling light sensor, and the Oxygen sensor. A SeaBird underwater pump was also included in the sensor suite.
It should be noted that whenever the data are of questionable value, 50.000 is written in the particular data field.
Unless otherwise indicated, these data have not been post-processed.

Note: Some variables have been eliminated from the display but are nevertheless available. These variables include: oxycurrent, oxytemp, tempco, and echo.

国家海洋数据中心（NODC）登录号0107210的数据集，包含1993年5月22日至1997年5月17日期间，在ALBATROSS IV、ENDEAVOR、OCEANUS与SEWARD JOHNSON科考船上，于AL9306、AL9403II、EN268、OC301、OC303、SJ9503、SJ9507航次中，在几内亚湾、地中海西盆、北大西洋、北太平洋及第勒尼安海采集的剖面数据、生物数据与物理数据。本数据集涵盖盐度（SALINITY）、静水压（HYDROSTATIC PRESSURE）、西格马-西塔（SIGMA-THETA）、荧光（FLUORESCENCE）、位温（Potential temperature, θ）以及透射率（TRANSMISSIVITY）。数据采集所用仪器包括温盐深仪（CTD）。该数据集由美国国家海洋渔业局的Greg Lough与James P. Manning，以及华盛顿州立大学的Steve M. Bollens作为GB项目的一部分采集完成。生物与化学海洋学数据管理办公室（BCO-DMO）于2013年4月26日将本数据集提交至NODC。

以下为BCO-DMO提供的摘要文本：
多开启/闭合网与环境传感系统（MOCNESS）基于塔克拖网原理（Tucker, 1951）。本次所用的MOCNESS系统为三套网具系统之一。MOCNESS-.25搭载9块面积为1/4平方米的矩形网面，网目通常为64微米。在三套MOCNESS系统中，水下单元每2秒向甲板单元发送一组采用压缩十六进制格式编码的数据帧，数据帧包含温度、深度、电导率、网框角度、流量计数、时间、开启网具编号以及网具启闭状态；并每4秒将数据从甲板单元传输至微型计算机。温度（精度约0.01℃）与电导率通过SEABIRD传感器测量，常规使用改装型TSK流量计。温度传感器、电导率传感器与流量计均安装于网框顶部，当网框以45°拖曳角姿态时，传感器朝向水平方向。计算机接收每组数据串后，将计算盐度（精度约0.01‰S）、位温（θ）、位密度（sigma）、网具的斜向与垂直运动速度，以及每张网具过滤的近似水体体积（Wiebe等, 1985）。此外，还通过安装于网框的另外四类传感器采集数据：透射仪、荧光计、下行光传感器与溶解氧传感器。传感器套件中还包含SeaBird水下泵。

需注意：当数据质量存疑时，对应数据字段将填入50.000。除非另有说明，本数据集未经过后处理。
