Notes: IR = infrared. Hydrates were identified visually and were implied from IR scans, based on low core liner temperatures. Curated depths (top of sample depth) and depths calculated from IR image processing (which represent the coldest spot in a cold part of the core) agree reasonably well. However, refined data acquisition and image processing should improve this correlation.
