(1) Low-density clathrate structures have been observed and modeled at below-ambient pressures and temperatures.(2) However, it is unclear how much natural gas is tied up in clathrates .(3) Methane hydrates are not the only clathrates that can form in the deep ocean environment.(4) Technically they are clathrates (crystalline solids), similar to ice except that they are not of uniform molecular composition: part of their structure is provided by a u2018guestu2019 molecule.(5) This creates cage structures called clathrates , which release gas on the tongue as the ice melts, producing a fizzy sensation in the mouth.
