Provision of Log Data Reduction and Database Services for Scientific Ocean Drilling

为科学海洋钻探提供测井数据处理和数据库服务科学海洋钻探的结果和发现与广泛的社会、教育和公共利益有着广泛的相关性。科学海洋钻探最重要的方面之一是存储和提供在探险期间获得的测井数据。拉蒙特-多尔蒂地球观测站（LDEO）一直参与科学海洋钻探与美国国家科学基金会从海洋钻探计划（ODP）通过目前的国际海洋发现计划（IODP）。迄今为止，已有570多个科学钻探孔被上传到数据库LogDB，包括超过33公里的钻探间隔的数据，2013年有超过37 000次网站访问以下载数据。对于拟议的工作，LDEO将继续为科学家提供未来科学考察的质量控制测井数据集，并将保持历史测井数据的访问。此外，LDEO将与主要数据库团体合作，使LogDB及其相关科学产品得到广泛传播。这将通过将LogDB与其他国家科学基金会支持的数据库和设施连接，扩大科学海洋钻探数据的使用和影响，增加更广泛的科学界对IODP日志数据的访问。技术说明：该提案的目标是为科学家提供未来科学考察的质量控制的测井数据集，并保持历史测井数据的访问。为了实现这一目标，将把美国钻井船JOIDES Resolution的测井数据传输到海岸进行数据处理和QA/QC，并将产生的标准和图像文件传输回船上，供每次勘探使用。在每次航行结束时，该数据集将上传到数据库LogDB，供特定科学界在航行后以密码保护方式访问。LDEO将继续维护LogDB，它提供了一个支持Web的数据库，可以安全地存储、搜索和检索DSDP、ODP和IODP收集的日志数据。LogDB有四个组件：在安全文件系统中安全存储原始和精简日志数据文件;包含用于索引和数据查询的日志元数据的关系数据库;提供数据搜索和检索以及访问关于数据精简和QA/QC步骤的文档的Web界面;以及一组基于REST的Web服务，其为第三方数据工具提供接口以直接与数据库交互。LDEO钻孔研究组（BRG）将与欧洲和日本的测井作业组合作，以确保IODP收集和分发的测井数据在所有平台上保持一致。在这项工作中，BRG将以尽可能无缝的方式为JOIDES Resolution上的科学家和国际社会提供高质量的日志数据访问。LDEO程序旨在为美国船舶运营商Texas A M University（TAMU）提供高效的运营和成本效益，并通过最先进的数据库技术增强LogDB用户体验。

Provision of Log Data Reduction and Database Services for Scientific Ocean DrillingThe results and discoveries of scientific ocean drilling have broad relevance to a wide range of societal, educational, and public interests. One of the most important aspects of scientific ocean drilling is storing and making accessible well log data obtained during expeditions. The Lamont-Doherty Earth Observatory (LDEO) has been involved in scientific ocean drilling with the NSF from the Ocean Drilling Program (ODP) through the current International Ocean Discovery Program (IODP). To date, more than 570 scientific drilling holes have been uploaded into the database, LogDB, including data for more than 33 km of drilled intervals, with more than 37,000 website visits for 2013 for data download. For the proposed work, LDEO will continue to provide scientists with quality-controlled well log data sets from future scientific expeditions and will also maintain historic well log data access. In addition, LDEO will collaborate with key database groups to enable LogDB and its associated scientific product to be broadly disseminated. This will broaden the use and impact of scientific ocean drilling data by connecting LogDB to other NSF-supported databases and facilities, increasing the accessibility of IODP log data to the broader scientific community. Technical Description: The goals of this proposal are to provide scientists with quality-controlled well log data sets from future scientific expeditions and to maintain historic log data access. To accomplish this, log data will be transferred from the U.S. drillship, JOIDES Resolution, to shore for data reduction and QA/QC, with the resulting standard and image files transferred back to the ship for use during each expedition. At the end of each cruise, this dataset will be uploaded to the database, LogDB, for post-cruise, password-protected access for specific the scientific community. LDEO will continue to maintain LogDB, which provides a web-enabled database to safely store, search, and retrieve log data collected by DSDP, ODP, and IODP. LogDB has four components: secure storage of original and reduced log data files in a secure file system; a relational database containing log metadata for indexing and data queries; a web interface providing data search and retrieval, as well as access to documentation on data reduction and QA/QC steps; and a set of ReST-based web services, which provide an interface for third party data tools to interact directly with the database. The LDEO Borehole Research Group (BRG) will collaborate with logging operation groups in Europe and Japan to insure that log data collected and distributed by IODP are consistent across all platforms. In this effort, BRG will provide high quality log data access in as seamless a manner as possible for scientists onboard the JOIDES Resolution and to the international community. LDEO procedures have been designed to be operationally efficient and cost effective for the U.S. ship operator, Texas A&M University (TAMU), and to enhance LogDB user experiences with state-of-the-art database technology.
