*  The weight is estimated based on the configuration of core, the known weights of the core head and core barrels, and estimated weights for the core couplings, core cutter and core catcher.

**  % Recovery is calculated as the length of recovered sediment divided by the penetration of the core barrel as recorded by the mud line on the exterior of the core.

***  Core overpenetration - 11CDH estimated to be 1 to 2 meters, 14CDH estimated to be 5 meters
