Abstract:
Temperature and salinity data were gathered in the Bay of Sept-Îles from the 16th to the 18th of May, 2018, as part of the Canadian Healthy Oceans Network (CHONe II) program. Repeated passages were then conducted at the mouth of the Bay, between the port of Sept-Îles and Pointe à la Marmite during one semidiurnal tide cycle (12 h). Although other measurements were collected continuously, CTD data were gathered once every three passages at the beginning, middle, and end of the passage. The data were collected from the hydrological survey vessel F. J. Saucier using a Sontek CastAway CTD probe.

Description
-----------
These profiles were gathered using a Sontek CastAway CTD probe. Sensors recorded the following parameters:
* temperature (degrees Celsius)
* salinity (practical salinity units)
* density (kg / m^3)
* depth (meters)
* pressure (decibars)
* speed of sound (m / s)
* conductivity (MicroSiemens / cm)
* specific conductance (MicroSiemens / cm)
The profiles were gathered at the mouth of the bay in May 2018 while conducting repeated passages during one semidiurnal tidal cycle.
Processing
----------
Data should be viewed as raw. Only basic quality were done on depth, temperature and salinity. Water colder than -1.8 or warmer than 40 degrees Celsius were marked as bad. Water with salinity less than 10 PSU were marked as questionable, since this is a coastal area. Negative depths were also marked as bad.
The flag meanings are as follows:
* 0: raw
* 1: good
* 3: questionable
* 4: bad
* 5: modified
* 9: missing
Users should apply their own quality checking methods.
Positions were logged by the CTD on most casts, but this failed in some others. For these casts, positions were written down and edited into the data file headers manually. The positions of these casts were:
* ismfj18_0_24: 12:55, lon 50 11.270 N; lat 66 30.490 E
* ismfj18_0_25: 13:00, lon 50 11.340 N; lat 66 29.674 E
* ismfj18_0_27: 13:05, lon 50 11.385 N; lat 66 28.920 E
* ismfj18_0_28: 17:19, lon 50 11.214 N; lat 66 26.133 E
* ismfj18_0_29: 17:30, lon 50 10.257 N; lat 66 25.943 E
These positions were measured using a handheld Garmin GPS device.
