A semi-simulated dataset for testing and demonstrating flowthrough
respirometry analyses. Contains one column of numeric time data (col 1 in
mins), four columns of outflow oxygen concentrations (cols 2:5), four columns
of inflow oxygen concentrations (cols 6:9), and four columns of delta oxygen
concentrations (cols 10:13, which is simply the numeric difference between
paired columns of outflow and inflow). There is also a column of inflow
oxygen concentrations as recorded from a shared header tank (col 14,
$oxy.header) supplying all chambers, to use as an alternative to the
individual inflow oxygen recordings. Lastly, there is a column of temperature
data (col 15, $temperature in °C).
flowthrough_mult.rdA data frame object consisting of 3740 rows (approx 62 mins of data),and 15 columns: time (col 1), oxygen outflow concentrations (cols 2,3,4,5), inflow concentrations (cols 6,7,8,9 each paired with the respective outflow column, the fourth being a control), delta oxygen values (cols 10,11,12,13 or difference between outflow and inflow concentrations), inflow concentrations recorded in a shared header tank (col 14), and temperature (col 15).
Outflow (2:5) and inflow (6:9) columns are paired, with the first three containing specimens, and the fourth an empty control respirometer, or "blank" experiment (oxy.out.blank, oxy.in.blank) to determine background respiration.
The third paired dataset (col 4 and col 8 pair) has a period of higher rates at around the 40 minute timepoint, where the specimen increases its activity then slowly recovers to routine respiration levels.
