The data shown in the plots were obtained from four fixed buoys in the Cockburn Sound. Each buoy has an instrument (EXO2, YSI) with sensors for temperature, salinity, dissolved oxygen (DO), and photosynthetic active radiation (PAR). The instrument is attached to a winch, which does hourly vertical profiles collecting data at each metre. Each vertical profile takes about 20 minutes. For data visualisation and to remove outliers, a Loess model was fitted to each vertical profile.
Loess model is a nonparametric technique that fits a smooth curve through each data point in the vertical profile. The data for each parameter is presented as curtain plots (parameter data is colour coded) with time on the horizontal axis and depth on the vertical axis.
