Gas Hydrate in Nature

October 1, 2021

This geonarrative combines the text and imagery of USGS Fact Sheet 3080 with additional supporting imagery. Except for headings used to organize the text in the geonarrative and an updated name for the coastal and marine program at the USGS, the text is exactly the same as USGS Fact Sheet 3080, with an updated timeline diagram.

Hands pull a chunk of frozen ice from a core collection tube, the ice is lumpy and interspersed with dark sediment.
In 2010, USGS researcher Brian Edwards recovers white chunks of gas hydrate (methane ice) mixed with gray sediment from a metal core sample tube retrieved from the seafloor in the Arctic Ocean at a water depth of approximately 8,000 feet.
