VPR CTD data combined with tabulated ROIs
Description
A dataframe representing CTD data which has been merged with tabulated
ROIs in each category, produced by vpr_ctdroi_merge
Usage
ctd_roi_merge
Format
A dataframe with 28 variables
- time_ms
Time stamp when ROI was collected (milliseconds)
- conductivity
Conductivity collected by the VPR CTD
- pressure
Pressure measured from the VPR CTD in decibars
- temperature
Temperature measured from the VPR CTD in celsius
- salinity
Salinity measured from the VPR CTD
- fluor_ref
A reference fluorescence baseline provided in millivolts by the VPR CTD for calibrating fluorescence_mv data
- fluorescence_mv
Fluorescence in millivolts from the VPR CTD (uncalibrated)
- turbidity_ref
A reference turbidity baseline provided in millivolts for calibrating turbidity_mv
- turbidity_mv
Turbidity in millivolts from the VPR CTD (uncalibrated)
- altitude_NA
Altitude data from the VPR CTD
- day
Day on which VPR data was collected (from AutoDeck)
- hour
Hour during which VPR data was collected (from AutoDeck)
- station
Station identifier provided during processing
- sigmaT
Density caluclated from temperature, pressure and salinity data
- depth
Depth in metres caluclated form pressure
- roi
ROI identification number
- categories
For each category name (eg. bad_image_blurry, Calanus, krill), there is a line in the dataframe representing the number of ROIs identified in this category
- n_roi_total
Total number of ROIs in all categories for each CTD data point
