ctd_roi_merge {vprr}R Documentation

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
