Hydrographic CCGS Louis S. St-Laurent Cruise CTD and Geochemistry Data 2003-2007

This data set contains data from late summer hydrographic cruises conducted in years 2003 through 2007. Conductivity, Temperature, and Depth (CTD) data for each year is archived in a zip file. The zip file contains an ascii formated file for each CTD station. Some stations include data from both the down cast and upcast. Some of the zip files also contain as well as a single matlab-format file combining all the station data. Cruise documentation is also available. Geochemistry data is provided in a separate spreadsheet. The CTD and geochemistry data were produced by researchers at the Institute of Ocean Sciences, Fisheries and Oceans Canada. The principal investigators are Fiona McLaughlin, Eddy Carmack, Sarah Zimmermann, Michiyo Kawai (IOS) and Chris Guay.

本数据集涵盖2003年至2007年夏末开展的水文调查航次实测数据。各年度的电导率、温度和深度（Conductivity, Temperature, and Depth，简称CTD）数据均归档为zip压缩包。每个压缩包内包含对应各CTD测站的ASCII格式数据文件；部分测站同时包含下行测量与上行测量的实测数据。部分压缩包还附带一份整合了所有测站数据的Matlab格式单文件。此外，本次航次的相关文档资料亦可获取。地球化学数据则存放于单独的电子表格中。本数据集的CTD与地球化学数据由加拿大渔业与海洋部海洋科学研究所（Institute of Ocean Sciences, Fisheries and Oceans Canada）的研究人员生成，主要研究者包括Fiona McLaughlin、Eddy Carmack、Sarah Zimmermann、Michiyo Kawai（IOS）以及Chris Guay。
