Special issue}, month = {Mar}, note = {P(論文), Experimental data on the dissociation rate of air-hydrate crystals in Vostok cores, Antarctica, and Dye-3 cores, Greenland, during their long term storage revealed that dissociation of the crystals affected the volume expansion of deep ice cores. The temperature dependence of the dissociation rate of the air-hydrate crystals determines the optimized storage temperature and the time period for both the transportation of ice cores and their long storage plans. The results also suggest that deep ice cores should be stored in the shape of bulk samples to prevent the from dissociating, including the air-hydrate crystals.}, pages = {306--313}, title = {Optimized storage condition of deep ice core samples from the viewpoint of air-hydrate analysis}, volume = {49}, year = {1994} }
