CSIRO O&A Sediment sampling sites Overview ( 1986 to present)

Sampling of sediments has occurred on many voyages using sleds, dredges, grabs and corers. Records of sampling have been taken from a variety of sources and merged into one product. Two principal sources are the CSIRO Exploration and Mining voyages in 1990's and Geoscience Australia MARine Sediments (MARS) database downloaded in June 2013. MARS was queried for all RV Franklin and RV Southern Surveyor records. The rest of the sites have been extracted from voyage summary reports and where possible the MARS records have had additional details added including water depth and on-board commentary on the samples collected. Many of the sampling events do not have dates although the position is recorded quite accurately. Metadata records are missing for some voyages and will be added. In the interim, refer to the voyage reports for details including stations that failed to acquire samples.本数据集收录了多次科考航次中利用海底拖橇、挖泥斗、采样抓斗与岩心取样器获取的沉积物采样记录。所有采样记录源自多类数据源，并已整合为单一数据集产品。本数据集的两大核心数据源分别为20世纪90年代的联邦科学与工业研究组织（CSIRO）勘探与采矿科考航次数据，以及2013年6月下载的澳大利亚地质调查局海洋沉积物（MARS）数据库。其中已针对MARS数据库检索获取全部“富兰克林号”（RV Franklin）与“南方考察者号”（RV Southern Surveyor）科考船的采样记录。其余采样点位数据均提取自科考航次总结报告；同时尽可能为MARS数据库的采样记录补充水深、采集样品的船上现场批注等额外细节。多数采样事件未记录具体采样日期，但采样点位的定位数据精度较高。部分科考航次的元数据记录暂缺，后续将予以补充完善。在此期间，若需了解包括未成功获取样品的采样站位在内的详细信息，请查阅原始航次报告。
