 note = {Knowledge of cage occupancies and hydration numbers (n) of naturally occurring gas hydrate in a local
environment is important for the improvement in global estimates of hydrate-bound natural gas. We report
on local differences in cage occupancies and hydration number of gas hydrates from Lake Baikal. Natural
gas hydrates of both structures I and II (sI and sII) and ranging in composition from pure CH4 to mixed gas
hydrate containing up to 15% C2H6 are compared. The average hydration numbers are n = 6.1 for the sI
CH4 hydrates recovered from the Malenky and Bolshoy mud volcanoes, n = 6.2 for the sI hydrates,
containing 3?4% C2H6 recovered from the K-2 mud volcano, and n = 6.9 for the sII hydrate containing
about 15% C2H6 recovered from the K-2 mud volcano. The differences in hydration number are due to the
differences in the small cage occupancy of CH4 among the samples studied.},
