Characterization Techniques

X-Ray Micro Computed Tomography (X-ray microCT)
X-ray microCT provides a non-destructive three-dimensional analysis of the microstructure of sea ice with 15 micron resolution. This enables us to examine the brine channel networks within our samples.

Ion Chromatography (IC)
This technique allows us to measure the concentration of different salts, such as chloride, bromide, nitrate, phosphate, sulfate, sodium, potassium, and calcium. Knowledge of the salt concentrations in both the snow and ice will aid us in tracking the transport of bromide from the ocean into the atmosphere.

Synchrotron X-Ray MicroFluorescence
We use Argonne National Laboratory's Advanced Photon Source to image our samples using synchrotron x-ray micro-fluorescence. This enables us to determine the microstructural location of salts within our samples. Click here for a link to the summary video describing our work at Argonne.
