Noted advantages of master thesis    The Ms thesis provides a good overview of methods for gas hydrates prospecting and mining. YU ZENGZHAO made calculations of the hydrate stability zone in the Deryugin Basin, and showed the dependence of the stability zone thickness on the gas composition. Thus, Yu ZENGZHAO become familiar with the methods of predicting submarine gas hydrates formation areas using the Deryugin Basin as an example.

Noted disadvantages of master thesis:   References to figures are not always correctly indicated in the text of the master's thesis. References to literature in the text are also not always placed correctly. It would be worth doing more calculations of the thickness of the hydrate stability zone. __________________________________________________________________________________________________________________________________________________________
Scientific Supervisor 's conclusion    The results of YU ZENGZHAO research meet the requirements for final qualifying works.
