IODP Expedition 310: Tahiti Sea Level
Figure 10
Imaging results of M0015A illustration the extremely hostile borehole conditions. Cavities up to 0.5 m in size were encountered which cannot be cored obviously. Although the (conventionally calculated) core recovery was 57.47 %, the image logs clearly show that the true recovery (including cavities) was much higher, potentially higher than 90 percent.
