Data and Sample Management for Scientific Drilling Projects must be a comprehensive service in the long term. The main objective is to acquire all information about the technical and scientific works performed during the operational phase in both the field and lab. Well-documented sample material gets prepared for sampling parties and consequent permanent storage. The resulting output provides basic and validated data sets; a common reference indespensible when most of the science team members start their scientific work.
As data is one of the major products of a scientific drilling project, data management is essential for a successful project and potential follow-up operation and publications. It is a long-term task that extends throughout the entire project and deserves a high-level of attention from both the project management and the entire science team. See figure for data management phases of an ICDP project.
All data gathered during the project forms the basis of the Operational Data Set, which is accessible for all science team members during the projects’ drilling and sampling phases as well as for the entire science community after the moratorium period. For data acquisition and sample curation ICDP provides a data management system, the mobile Drilling Information System (mDIS).
Sampling management in ICDP is setup in line with the fair principles (Findability, Accessibility, Interoperability, and Reuseability). While the projects main scientific objectives determine the sampling strategy, the logistics are guided by a sampling plan to secure sample quality, unique sample identification and archiving of the sample material and the related meta data (Operational Data Set). In addition, an early planning of the long-term core and sample preservation and storage is crucial to guarantee the long-lasting success of a project.
The finalization of the sampling plan and the core handling are topics of the training course on data and sample management, provided by ICDP-OSG 3 - 6 month ahead of the operation phase of each approved ICDP drilling project.
For all ICDP drilling projects the data and sample management training is mandatory and costs should be part of the budget plan.
Within the training course the data and sample management cycles, the details for data acquisition, core handling procedures and on-site workflows will be discussed and developed. The data acquisition tool used in all ICDP projects, the mobile Drilling Information System (mDIS), will be presented and adapted for the specific requirements of the project.
The list of participants should include at least one PI and a person responsible for the data and sample management in the field and in the laboratory (if applicable). Commonly, 3 – 5 on-site science team members complete the list of participants to support the implementation of the onsite sample workflow. It is preferential, if at least the data manager has some skills in computer handling and data acquisition. It is intended that the data manager provides guidance and education of additional staff entering data, oversees consistency and quality of the data acquisition and functions as relay for distributing reports.
The mobile Drilling Information System (mDIS) is a database management application developed and provided by ICDP for capturing and curating meta data on geological cores and samples, drilling progress, and lithology. In addition, images, surveying logs and driller reports are collected. During the operational phase, data reports and sample labels support curating and archiving of the samples. Following the operational phase, mDIS contains the basic data set, which needs to be compiled in the Operational Data Set & Report.
mDIS will be deployed and adapted during the mandatory data and sample management course with the possibility for remote follow-up training and online support during the field operation. It is designed to be used onsite in parallel with daily operations to perform the centralized data acquisition alongside a defined workflow.
