Sydney Harbour pH data 2016

Full description

pH, salinity, temperature and some pCO2 data collected in Sydney Harbour at the Sydney Institute of Marine Sciences facility at Chowder Bay. The pH data is derived from a fluorescence-based measuring technique. The dataset consists of two Microsoft Excel spreadsheets, each containing multiple worksheets.

The first spreadsheet, titled Runcie et al. 2018 April2016 data.xlsx, contains data derived from experiments run at Chowder Bay, NSW, Australia, in April 2016. Measurements were taken from water pumped from approximately 1-2m depth to 2-3m above water level. Water was debubbled and run through a clear tube, fluorescence spots were installed on the inside of this tube for measuring pH and pCO2. Temperature was measured from water in the debubbler chamber prior to the measuring tubes. Flow through rates were high to minimise a temperature difference between measured water and the bulk seawater.

The second spreadsheet, titled Runcie et al. 2018 December 2016 dataset.xlsx, contains data derived from experiments run at Chowder Bay, NSW, Australia, in December 2016. Measurements were taken from water measured at a fixed location approximately 1-2m depth below the water level. The autonomous pH measuring device was attached to a pier under the wharf at Chowder Bay. Temperature was measured from ambient water.

In both spreadsheets, data are provided in worksheets for each 24h period, midnight to midnight. Each worksheet is labelled with the date in Australian date format. Combined raw data and sorted data worksheets are also provided. Data and charts are then provided for each parameter. Please see accompanying paper for description of how data were calculated.
