The Integrated Ocean Drilling Program (IODP) and the International Continental Drilling Program (ICDP) use many new technologies to increase the quality of core data. A problem with drilling deep oceanic or continental crust, as well as shallow fractured rock or karstic formations, is that core recovery can be low, and much of the recovered material often consists of small, disrupted core pieces that are frequently biased toward particular types of rocks (lithologies). Even when core recovery is high (in the case of sedimentary formation), recovered cores are not always oriented;as a result, detailed structural and paleomagnetic studies are impaired.
