Ground subsidence caused by permafrost thawing causes the formation of thermokarst ponds, where organic compounds from eroding permafrost accumulate. We photolyzed water samples from two such ponds in Northern Quebec and discovered the emission of volatile organic compounds (VOCs) using mass spectrometry. One pond near peat-covered permafrost mounds was organic-rich, while the other near sandy mounds was organic-poor.

- Raman spectroscopy is a powerful technique for molecular identification, producing specific spectra linked to molecular structures, and SERS enhances its sensitivity for analyzing mixtures quickly.
- The study explores the integration of deep learning algorithms with SERS to effectively differentiate bile acids, which have minor structural variations and are relevant in medical research for gut health.
- A convolutional neural network model was successfully developed to classify SERS spectra of five different bile acids, demonstrating reliable identification even at low concentrations.
