RBRCTD_s

RBRCTD summary data

The RBRCTD measures conductivity, water temperature and seawater pressure.

It was installed along with the SBECTD sensor on the 12m node at approximately 11 m depth and ran for over a year (though it fouled fairly soon after deployment).

Most of the data parameters include valus for the mean and median value as well as the standard deviation of the variable. The table below shows the field name suffix used to differentiate amoung the different values:

Field name	Description
_mean	The mean value of the variable over the averaging period
_m50	The median value of the variable over the averaging period
_std	The standard deviation of the variable over the averaging period
_length	The number of valid data points collected over the averaging period

Here is the list of field names:

Field name	Description	Units
Year	The year the data were collected	n/a
Yday	Decimal year day	UTC, January 1 at 00:00 is 1.0
MO	The month the data was collected	UTC
DA	The day the data were collected	UTC
HH	The hour the data were collected	UTC
MM	The minute the data were collected	UTC
SS	The second the data were collected	UTC
lrec_rbrctd	Total number of records collected during averaging period	n/a
