category_conc_n.RdA 'binned' dataframe from sample VPR data, including concentrations
of each category, where each data point represents a 5 metre bin of
averaged VPR data. Produced using vpr_roi_concentration
category_conc_nA dataframe with 21 variables
Depth calculated from pressure in metres
The minimum depth of the bin in metres
The maximum depth of the bin in metres
The difference between minimum and maximum bin depth in metres
The minimum time in seconds of the bin
The maximum time in seconds of the bin
The difference between minimum and maximum time in a bin, in seconds
The number of ROI observations in a bin
The concentration of ROIs in a bin, calculated based on image volume and number of frames per bin
Temperature measured from the VPR CTD in celsius (averaged within the bin)
Salinity measured from the VPR CTD (averaged within the bin)
sigma T density calculated from temperature, salinity and pressure (averaged within the bin)
Fluorescence measured by the VPR CTD in millivolts (uncalibrated) (averaged within the bin)
Turbidity measured by the VPR CTD in millivolts (uncalibrated) (averaged within the bin)
The mean time in which bin data was collected, in hours
The number of frames captured within a bin
The volume of the bin sampled in metres cubed
Identifier of the tow-yo section which bin is a part of, either ascending or descending, appended by a number
The maximum depth of the entire VPR cast
The category in which ROIs in bin have been classified by Visual Plankton
