The presented work describes first principles for monitoring gas hydrate formation and dissociation in
solution by evaluating state-responsive IR absorption features of water with fiberoptic evanescent field
spectroscopy. In addition, a first order linear functional relationship has been derived according to Lambert
Beer’s law, which enables quantification of percentage gas hydrate within the volume of water directly
probed via the evanescent field. Moreover, spectroscopic studies evaluating seafloor sediments collected
from a gas hydrate site in the Gulf of Mexico revealed minimal spectral interferences from sediment matrix
components, thereby establishing evanescent field sensing strategies as a promising perspective for
monitoring the dynamics of gas hydrates in oceanic environments.
