R Documentation

VPR CTD data combined with tabulated ROIs

A dataframe representing CTD data which has been merged with tabulated ROIs in each category, produced by vpr_ctdroi_merge

ctd_roi_merge

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
