Part 1: In the previous Integrated Ocean Drilling Program, NSF supported operation of the U.S. drillship JOIDES Resolution (JR) through a contract to the Consortium for Ocean Leadership (COL). COL, as prime contractor, oversaw subcontracts to Texas A&M University (as "Prime Contractor" for operating the JR) and Columbia University (as "Logging Contractor"). The Borehole Research Group (BRG), under PI Goldberg, provided downhole logging services that included management of the logging subcontractor Schlumberger as well as logging data reduction and quality control, and management of the IODP logging database. These logging services are primarily geophysical measurements done remotely in the drilled borehole, such as borehole wall rock or sediment (formation) resistivity, geochemistry, seismic properties, or magnetic properties. In the current International Ocean Discovery Program (IODP), a new NSF Cooperative Agreement to Texas A&M University as JOIDES Resolution Science Operator (JRSO) replaced the contract for FY2015. At the time of this award, it was recognized that a need existed to maintain the IODP logging database and the data reduction and quality control activities provided under the previous logging subcontract, activities that the JRSO at award could not easily or inexpensively provide. Thus, NSF made previous 3 year awards to the PI to provide these services in FY 2015-2017 and FY 2018-2020, an arrangement that has worked very well with no issues identified during review by independent NSF panels examining JR facility operations performance in FY2015, 2016, 2017, and 2019. An NSF panel examined JR facility operations fo FY2018 and further identified no performance issues.This award represents a new award to the PI to continue to provide these shipboard downhole logging data services, including data reduction, quality control, support of a user-accessible database containing these logging data, and archiving of the data in easily retrievable form in an international database and in a deep archive supported by there U.S. Government. This award will support these services for four additional years, through the end of the IODP.Part 2: The award will provide support for four years of the following services: 1) Rapid data reduction and quality control of logging data acquired aboard JOIDES Resolution drillship International Ocean Discovery Program (IODP) Expeditions by the logging subcontractor Schlumberger, with subsequent return of the reduced data in near real-time to the Expedition Science Party aboard the drillship; 2) Archiving of raw and reduced logging data within the existing IODP logging database LogDB housed at Columbia University;3) Storing the logging data following FAIR (findable-accessible-interoperable-reusable) criteria in the CERN-supported international data base, publishing Digital Object Identifiers (DOI's) for each well log dataset;4) Maintain and enhance web services for automated query and retrieval of data from LogDB; 5) Submit full sets of raw and processed data for deep archiving to the National Centers for Environmental Information; and 6) Provide support for LogDB users, especially neophytes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

第一部分：在之前的综合海洋钻井计划中，NSF通过与海洋领导联盟（COL）签订合同，支持美国钻井船JOIDES Resolution （JR）的运营。COL作为主承包商，负责监督分包给德州农工大学（作为JR的“主承包商”）和哥伦比亚大学（作为“伐木承包商”）的合同。PI Goldberg领导下的钻孔研究小组（BRG）提供了井下测井服务，包括管理测井分包商斯伦贝谢、测井数据减少和质量控制，以及管理IODP测井数据库。这些测井服务主要是在钻孔中进行远程地球物理测量，如钻孔围岩或沉积物（地层）的电阻率、地球化学、地震性质或磁性。在当前的国际海洋发现计划（IODP）中，NSF与德克萨斯a&m大学签订了一份新的合作协议，作为JOIDES分辨率科学运营商（JRSO）取代了2015财年的合同。在签订该合同时，人们认识到有必要维护IODP测井数据库以及根据以前的测井分包合同提供的数据减少和质量控制活动，这些活动是JRSO在签订合同时无法轻松或廉价地提供的。因此，NSF与PI签订了前三年的合同，在2015-2017财年和2018-2020财年提供这些服务，这一安排非常有效，独立的NSF小组在2015、2016、2017和2019财年审查JR设施运营绩效时没有发现任何问题。NSF小组检查了JR 2018财年的设施运营情况，并进一步发现没有性能问题。该合同代表了PI继续提供这些船上井下测井数据服务的新合同，包括数据减少、质量控制、支持包含这些测井数据的用户可访问数据库，以及以易于检索的形式将数据归档到国际数据库和美国政府支持的深度档案中。该合同将为这些服务提供额外的四年支持，直至IODP结束。第二部分：该合同将为以下服务提供四年的支持：1)对测井分包商斯伦贝谢（Schlumberger）在JOIDES Resolution钻井船国际海洋发现计划（IODP）探险船上获得的测井数据进行快速数据精简和质量控制，随后将精简后的数据几乎实时地返回给钻探船上的远征科学队；2)在哥伦比亚大学现有的IODP日志数据库LogDB中存档原始和简化的日志数据；3)按照FAIR（可查找-可访问-可互操作-可重用）标准将测井数据存储在cern支持的国际数据库中，并发布每个测井数据集的数字对象标识符（DOI）；维护和增强web服务，以便从LogDB中自动查询和检索数据；5)向国家环境信息中心提交完整的原始和处理数据进行深度存档；6)为LogDB用户，特别是新手提供支持。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
