RV Investigator Marine Science Cruise IN1801 (CSIRO Voyage Designation IN2018_V01), SR3 Plus Additional Southern Transects - Oceanographic Field Measurements and Analysis

Oceanographic measurements were collected aboard RV Investigator cruise in1801 (CSIRO voyage designation in2018_v01) from 11th January to 22nd February 2018, along CLIVAR Southern Ocean repeat meridional section SR3, followed by Adelie land shelf stations, small meridional sections along 150E (the south end of CLIVAR section P11S) and 132E, and several stations along CLIVAR zonal section S4. A total of 108 CTD vertical profile stations were taken on the cruise, most to within 14 metres of the bottom. Over 2800 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate, ammonia and nitrite), CFC's plus tracers (CFC-11, CFC-12, SF6 and N2O), dissolved inorganic carbon (i.e. TCO2), alkalinity, pH, C13/C14, genomics, HPLC, POC, chlorophyll, radiogenic isotopes, helium, ice nucleation, and Ca/Mg, using a 36 bottle rosette sampler. Full depth current profiles were collected by an LADCP attached to the CTD package. Upper water column current profile data were collected by a ship mounted ADCP (75 kHz). Trace metal rosette and in situ pump deployments were done at some of the CTD stations. Meteorological and water property data were collected by the array of ship's underway sensors. A large assortment of 29 drifting floats was deployed throughout the cruise. A detailed data report is included with the data set, with summary of all CTD data and important data quality information.The data set contains CTD 2dbar averaged data, and Niskin bottle data (core hydrochemistry of salinity, dissolved oxygen and nutrients, plus CFC-11, CFC-12, SF6 and N2O), in text and matlab formats. A WOCE (CCHDO) 'exchange' format version of the data is also available from the CCHDO data centre.

2018年1月11日至2月22日，"调查者号"（RV Investigator）科考船执行CSIRO航次in2018_v01（航次编号in1801）期间，沿CLIVAR南大洋重复经向断面SR3、阿德利地陆架站、150°E（CLIVAR断面P11S南端）及132°E附近小型经向断面，以及CLIVAR纬向断面S4的多个站点开展海洋学观测。本航次共采集108个温盐深仪（CTD）垂直剖面观测站数据，大多数观测深度距海底不足14米。使用36瓶多瓶采样器采集了超过2800份尼斯金采水瓶（Niskin bottle）水样，用于分析盐度、溶解氧、营养盐（磷酸盐、硝酸盐+亚硝酸盐、硅酸盐、氨氮及亚硝酸盐）、含氯氟烃（CFCs）及示踪剂（CFC-11、CFC-12、六氟化硫（SF6）、氧化亚氮（N2O））、溶解无机碳（即总二氧化碳TCO2）、碱度、pH值、碳13/碳14、基因组学数据、高效液相色谱（HPLC）分析数据、颗粒有机碳（POC）、叶绿素、放射性同位素、氦、冰核及钙/镁等参数。通过附于CTD组件上的低式声学多普勒流速剖面仪（LADCP）采集全水深海流剖面数据；上层水柱海流剖面数据由船载75 kHz声学多普勒流速剖面仪（ADCP）采集。部分CTD观测站还开展了痕量金属多瓶采样及原位泵采样。气象及水体特性数据由船载走航传感器阵列采集。航次期间共投放29个不同类型的漂流浮标。数据集包含一份详细的数据报告，其中涵盖所有CTD数据摘要及重要的数据质量信息。

本数据集包含文本及Matlab格式的CTD 2分巴平均数据，以及尼斯金采水瓶数据（核心水化学参数：盐度、溶解氧、营养盐，外加CFC-11、CFC-12、SF6及N2O）。此外，CCHDO数据中心还提供该数据的WOCE（CCHDO）交换格式版本。
