  The Mars Spectrometry 2: Gas Chromatography challenge was sponsored by NASA
and run on the DrivenData competition platform in 2022. This report describes
the solution which achieved the second-best score on the competition's test
dataset. The solution utilized two-dimensional, image-like representations of
the competition's chromatography data samples. A number of different
Convolutional Neural Network models were trained and ensembled for the final
submission.
