Ice Monitoring: Ice core analysis and snow pit data from Salluit fjord, Deception Bay and Kangiqsujuaq (Nunavik, Canada)

Ice cores from the landfast sea ice cover were extracted twice a year in Salluit, Deception Bay and Kangiqsujuaq (Nunavik, Canada) in 2015-2018. In 2017-2018, snow density, temperature and salinity was also measured. This sampling took place in January and April-May.

The ice cores are extracted using a Kovacs ice corer. After the ice cores are photographed, four (4) slices are sawed off at equally-spaced depths along the core. These slices are photographed and then melted for ice salinity measurements. Slices are generally between 2 to 3 centimeters and have a diameter of 15 centimeters. In 2016, the salinity measurements were done on-site using a portable refractometer. Since 2017, salinity measurements were done at a higher precision using a laboratory conductivimeter. Several ice cores from every January/April field campaigns were scanned in a laboratory CT-scanner to obtain high-resolution 3D density measurements. Some of these were converted into porosity. Snow temperature was measured along a vertical profile every 3 centimeters. Snow density was measured at one or two locations in the vertical snow profile. Snow salinity was measured by taking snow samples every 3 centimeters, melting them and then measuring the conductivity of the meltwater.
