Thermal imaging using infrared cameras is accepted by the scientific community as the most pragmatic way to determine the overall hydrate distribution in a sediment core. Dissociation/melting of gas hydrate is a strongly endothermic process which not only provides a self-preserving effect on the hydrate itself, but also cools the surrounding sediment and core liner material. Cool spots created by the unstable gas hydrate can therefore be detected on a thermal image of a fresh core that has been recovered quickly from beneath the seafloor. The thermal images allow cold regions to be quickly identified even before the camera has finished moving along the core. The final image remains on the screens, making thermal anomalies easy to locate while the core is marked and sampled. If necessary, the image can be enlarged and manipulated on screen to identify even the smallest details.
