This dataset contains NO "numeric" digital data, only scanned field log sheets, and hydrological sampling results sheets. The paper records have now been destroyed. The hydrological samples were collected at the wharf beside CSIRO Marine Laboratories, Castray Esplanade, Hobart, Tasmania between November 1984 and December 1986. Sampling was undertaken to determine if the water quality off the wharf was suitable for use in a planned for aquarium facility (This was not built). Sampling was conducted approximately daily at 2m, and weekly at 1m, 3m, 5m and 7m. Samples were analysed for temperature, salinity, dissolved oxygen, phosphate and nitrate. This "Coastal Station" was not part of the national coastal station scheme. - Although the links below are labeled "Graphic", as they are scanned images of the log sheets rather than "numbers", the sheets contain the values of analysed parameters. The PDF files are supplied individually, rather than as a single ZIP archive due to the large file size. Read Notes_on_CL_Logs.txt for a brief description of the contents of each PDF file.
