ChikyuOman 2017 Decision-Making Team

The Oman Drilling Project Phase 1 drill cores were described and analyzed onboard the JAMSTEC Drilling Vessel Chikyu from 15 July to 15 September 2017 (ChikyuOman2017). For these shipboard activities aboard Chikyu a Decision-Making Team (DMT) was established for effective decision making and sharing of information between the OmanDP PSC, the shipboard Co-Chiefs, Staff Scientists, the wider Science party, and the Center for Deep Earth Exploration (CDEX) Laboratory Managers. When wider discussion was required, for example budget-related issues, the DMT shared information with a broader constituency including the OmanDP PSC, ODS group leaders, and JAMSTEC administrators. Oversight of data and sampling will remain the responsibility of the OmanDP Sample Oversight and Allocation Committee (SOAC) but with refined procedures to approve and facilitate shipboard and personal sample requests (see below).

Oman Drilling Project Sample, Data, and Obligations Policies

These policies were developed to ensure transparent access by scientists to Oman Drilling Project samples and data. They are closely related to and similar to established policies used by IODP and other ICDP projects. Scientists who received samples and access data incurred obligations on their use and reporting of the science outcomes from research based on these samples or data. The distribution and use of all cores, samples, and data fall under oversight of the OmanDP Sample Oversight and Allocation Committee (SOAC), a subgroup of the Project Steering Committee.

Oman Drilling Project Sample Oversight and Allocation Committee (SOAC)

Prof. Damon Teagle: Chair of OmanDP SOAC; Principal Investigator OmanDP

Prof. Peter Kelemen: Chief Scientist of the Oman DP; Chair of PSC

Dr. Marguerite Godard: Geochemistry; Co-Chief ChikyuOman2018

Prof. Sobhi Nasir: Representative of the Oman Drilling Committee, co-ordinating sample allocations for Omani institutions

Prof. Alexis Templeton: Waters, gases, microbiology

Dr. Jürg Matter: Logging and hydrogeological data

Prof. Eiichi Takazawa: Co-Chief ChikyuOman 2017 and 2018

Prof. Katsu Michibayashi: Co-Chief ChikyuOman 2017 and 2018

The goals of the Oman Drilling Project sample policies were to ensure the:

Availability of samples and data to Science Party members so they can fulfill the objectives of the drilling project and their responsibilities to the OmanDP;

Dissemination of the scientific findings of the Oman Drilling Project coring, logging, sampling, experimentation, and related activities to gain maximum scientific exposure and public engagement;

Scientific community has access to findings and, following the moratorium periods, data and samples to encourage scientific analyses over a wide range of research disciplines; and

Preservation of core and cuttings material as an archive for future description and observations, nondestructive analyses, and sampling.

Sample and Data Requests

There are two classes of sample requesters: Members of the Science Party and Post-Moratorium Researchers. Both groups incur their own particular obligation once a data or sample request has been approved and delivered.

The Moratorium Period is defined as two and a half years following the end of the description of the cores. The Oman Drilling Project will be divided into two Science Parties relating to the 2016-2017 and 2017-2018 Phases of operation. For Phase 1 of the OmanDP the moratorium period will be from September 2017 until the end of February 2020. For Phase 2 of the OmanDP the moratorium period will be from September 2018 until the end of February 2021. To submit a sample/data request you must be registered with OmanDP (via the application form). Membership of one phase does not necessarily ensure membership in the other Science Party unless certain criteria are fulfilled. For example, membership of the OmanDP Phase 1 Science Party requires at least one of the following:

1) Participation on site during the Phase 1 drilling, sampling, logging, experiment operations, of OmanDP;

2) Contribution to the visual and/or instrumental logging of the Phase 1 Oman DP cores during ChikyuOman2017 (July-September, 2017); or

3) A financial contribution to Oman Drilling Project via one or more scientific research grants that provides funds for drilling operations and/or core logging onboard Chikyu.

In addition, the SOAC will also consider sample requests, on a case by case basis, from science groups who provide specific skills or approaches NOT provided by colleagues covered by 1, 2, and/or 3, above.

Personal sample requests are prioritized by the OmanDP SOAC. The SOAC encouraged a pooled sampling approach, as commonly used during IODP expeditions, to ensure that a comprehensive suite of geochemical, mineralogical, and physical properties measurements are made on a representative suite of shared samples/powders. The SOAC also encouraged boutique isotopic and other geochemical measurements to be initially undertaken on the well-characterized pool samples.

Post-moratorium researchers are those who submit sample and data requests after the specific OmanDP Phase moratorium period ends. Sample applications by educators and outreach institutions are also considered on a case-by-case basis.

All data and observations produced from the on-site drilling and logging phases and shipboard activities of the Oman Drilling Project will be published in this open access volume akin to the IODP Expedition Reports following the moratorium period. During the moratorium period, data and samples will be restricted to the Science Party of that phase of the OmanDP.

Requests for data or samples must be made through official OmanDP processes and use the OmanDP sample request form. These requests will be assessed by the SOAC and accepted, refined, combined, or rejected to ensure the best scientific outcomes. Core samples were generally only taken during the core logging activities (in 2017 onboard Chikyu) in a series of sampling meetings immediately following the description of each hole. To oversee these sampling events the SOAC delegated specific sample allocation to a shipboard team comprising the Co-Chief Scientists and Staff Scientists with assistance from the Curator. These teams resolved conflicts and ensured a fair and efficient distribution of samples. All sample request conflicts were resolved aboard.

Obligations for Members of the OmanDP Science Parties receiving Samples and/or Data

All members of the OmanDP Science Parties who receive samples or data incurr obligations to conduct research during the moratorium period and publish their data and results in an English language peer-reviewed scientific journal or a peer-reviewed data report that will supplement the open access OmanDP Initial Reports, within 48 months of the core description campaign. Failure to meet these obligations may result in the rejection of future sample requests and may influence participation in other aspects of the Oman Drilling Project.

All publications arising from the OmanDP operations must acknowledge the Oman Drilling Project using a modified version of the following wording:

This research used samples and/or data provided by the Oman Drilling Project. The Oman Drilling Project (OmanDP) was made possible through co-mingled funds from the International Continental Scientific Drilling Project (ICDP; Kelemen, Matter, Teagle Lead PIs), the Sloan Foundation Deep Carbon Observatory (Grant 2014-3-01, Kelemen PI), the National Science Foundation (Award NSF-EAR-1516300, Kelemen lead PI), NASA Astrobiology Institute (Award NNA15BB02A, Templeton PI), the German Research Foundation (DFG Grant KO 1723/21-1, Koepke PI), the Japanese Society for the Promotion of Science (JSPS grants 16H06347, Michibayashi PI; and KAKENHI 16H02742, Takazawa PI), the European Research Council (Adv grant 669972; Jamveit PI), the Swiss National Science Foundation (SNF grant 20FI21_163073, Früh-Green PI), Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the International Ocean Discovery Program JOIDES Resolution Science Operator (IODP JRSO), and contributions from the Sultanate of Oman Ministry of Regional Municipalities and Water Resources, the Oman Public Authority of Mining, Sultan Qaboos University, CNRS-Université Montpellier (France), Columbia University of New York (USA), and the University of Southampton (UK).

Publications should include the words Oman Drilling Project as keywords provided to the journal or book published of the manuscript.

Authors should send a PDF copy of the manuscript to the Chair and Vice-Chair of the OmanDP Project Steering Committee and the Project Director (Kelemen, Teagle, and Matter, respectively).

All data generated should be made openly available and either lodged in the OmanDP Proceedings Volume supplements as data reports or archived in an open access data repository (e.g., PetDP).

Authors wishing to publish scientific papers within the Moratorium Period must receive prior approval in writing by a majority of the scientific party and the support of the OmanDP Project Steering Committee. This approval will be coordinated by the OmanDP Project Manager, who will circulate the manuscript among the scientific party, tabulate responses, and notify the author of the scientific party’s decision. Unless specifically agreed, all publications within the Moratorium period must include the Oman Drilling Project Science Team in the authorship.


Acknowledgments

The Oman Drilling Project has received essential assistance from hundreds of volunteers, many of whom covered their own travel expenses as well as providing weeks to months of their time and effort without compensation. We are very grateful for this exceptional community effort.

The In-Country Manager of the Oman Drilling Project is Eng. Zaher Al Sulaimani, Director of the Oman Water Centre. It is likely that the Oman Drilling Project would not have succeeded without his wise guidance. We also thank his son, Mazin Al Sulaimani, for able and efficient assistance with logistics. Eng. Nehal Warsi served as Site Geologist, our dedicated and reliable representative, every day of drilling for two seasons (7 months in total) and also volunteered a month of his time to help with core description on board the Drilling Vessel Chikyu.

Funding for the Oman Drilling Project was generously provided by the International Continental Scientific Drilling Program (ICDP), the US National Science Foundation (NSF), the Sloan Foundation Deep Carbon Observatory (DCO), the US National Aeronautics and Space Administration (NASA), the European Research Council (ERC), the German Research Foundation (DFG), the Swiss National Science Foundation, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the Japanese Society for the Promotion of Science (JSPS), and the International Ocean Discovery Program (IODP). We are particularly grateful for advice from Dr. Uli Harms of ICDP, for support from JAMSTEC President Dr. Asahiko Taira, and for extensive assistance with proposal preparation from Dr. Nobu Eguchi at JAMSTEC. Special thanks also go to Jesse Ausubel of the Sloan Foundation Deep Carbon Observatory and Dr. Leonard Johnson and Dr. Dennis Geist of the US NSF.

We worked with several drilling contractors in Oman. We particularly thank GeoSolutions Engineering, owned and operated by Managing Director Sultan Al Saadi, who is assisted by the exceptionally able Driller Shaikh Oliullah (Wali) and by Geologist Abdul Rasak Tharayil. Their attention to quality and efficiency were above and beyond the call of duty and resulted in timely acquisition of 3200 meters of core with 100% recovery.

During core description onboard Drilling Vessel (D/V) Chikyu, we were ably assisted by the ship’s crew and technical staff. We particularly thank President Dr. Asahiko Taira, Dr. Kyoshi Suyehiro, Dr. Nobu Eguchi, Director of the Science Services Department, Center for Deep Earth Exploration (CDEX), Chikyu Laboratory Managers Dr. Lena Maeda and Dr. Yusuke Kubo, shore-based Expedition Manager Dr. Chiaki Igarashi, and Ms. Maya Takebayashi Noguchi at JAMSTEC.

We thank Dr. Jay Miller and Dr. Brad Clement at IODP JRSO at Texas A&M University (TAMU) for their advice and assistance in planning and organizing logistics and protocols for shipboard core description. In addition, Shana Lewis, Rhonda Kappler, Jean Wulfson, and Phil Rumford kindly joined us onboard D/V Chikyu to provide publications and curation support, and Lorri Peters and her team at JRSO TAMU worked extremely hard to edit and produce this volume.

Among the scientists involved with the Oman Drilling Project, a few deserve special thanks here. Project Manager Dr. Jude Coggon and Project Director Prof. Jürg Matter did an amazing, exceptional job of managing logistics, arranging contracts, and supervising operations in the field and during core description. Niigata University Prof. Eiichi Takazawa and his students found and mapped the drill sites at the crust-mantle transition zone. Nagoya University Prof. Katsu Michibayashi provided his own research funds to enable core description onboard D/V Chikyu in summer 2017. Katsu and Eiichi, together with Dr. Natsue Abe of JAMSTEC, Dr. Jude Coggon, and Prof. Damon Teagle of Southampton University, Dr. Marguerite Godard of the University of Montpellier, Dr. Michelle Harris of Plymouth University, and Prof. Peter Kelemen and graduate student Juan Carlos de Obeso of Columbia University, served as Co-Chief Scientists and Staff Scientists onboard D/V Chikyu. Prof. Alexis Templeton, Dr. Eric Ellison, and graduate student Katy Rempfert from the University of Colorado built and operated the biogeoscience laboratory on the drill site in January 2018.
