The Gas Hydrates Program manages the Hydrate Pressure Core Analysis Lab (HyPrCAL). When the facility opened in spring 2017, HyPrCAL was the first U.S. laboratory dedicated to the analysis of pressure cores, which are seafloor or permafrost samples recovered and maintained at in situ pressure and low temperatures in order to preserve gas hydrate in the specimens.
