Ocean Planet Workshop – Report

On 14 April 2019, more than 75 scientists from Australia, New Zealand, and abroad gathered in Canberra, at the ANU campus to formulate research themes and define new challenges for a new decadal (2024-2034) plan for global scientific ocean drilling. Many attendees were early- and mid-career researchers, highlighting the wide interest in continued engagement in this international program. Report HERE

Drilling for DNA

Diatom paleontologist Dr. Linda Armbrecht wants to use the past to understand how modern climate change might affect marine life. But the microfossils she looks at every day through the microscope are only one piece of the puzzle. To answer questions about how ocean ecosystems have changed over the last 12,000 years and beyond, she’s looking for something else in the mud: ancient DNA.

CALL FOR SCIENTISTS – IODP Expedition 386: Japan Trench Paleoseismology

Applications are invited from scientists in countries participating in IODP to join the Science Party for IODP Expedition 386: Japan Trench Paleoseismology. Scientists with expertise relevant to the objectives of the proposal may apply. The proposal upon which this expedition is based was submitted as IODP Proposal #866 ‘Japan Trench Paleoseismology’, subtitle ‘TRACKing past earthquakes in the sediment record along the Japan Trench: Testing and developing submarine Paleoseismology in the deep sea (JTRACKPaleoseismology)’.

The proposal describing the primary coring sites, as well as up-to-date expedition information, can be found on the Expedition 386 webpage http://www.ecord.org/expedition386/.

Background and Objectives

Expedition 386 aims to test and develop “submarine paleoseismology” in the Japan Trench, a promising approach that overcomes the limitations of short historical and instrumental records in revealing earthquake maximum magnitude and recurrence. Examining prehistoric events preserved in the geological record is essential to reconstruct the long-term history of earthquakes and to deliver observational data that help to reduce epistemic uncertainties in seismic hazard assessment for long return periods.

Expedition 386 will adopt a multi-coring approach using a mission-specific platform equipped with a giant piston corer to sample the shallow-subsurface at up to 40 mbsf to recover the continuous Upper Pleistocene to Holocene stratigraphic successions of trench-fill basins along an axis-parallel transect of the 7-8km deep Japan Trench. The cores from 18 proposed p (and/or 13 alternate) sites will be used for multi-method applications to characterize event deposits, for which the detailed stratigraphic expressions and spatio-temporal distribution will be analysed for proxy evidence of earthquakes. Expedition 386 can potentially lead to a fascinating record unravelling an earthquake history that is 10 to 100 times longer than currently available. This would contribute to a tremendous advance in the understanding of the recurrence pattern of giant earthquakes and earthquake-induced geohazards globally.

The project has three major objectives:

1. To identify the sedimentological, physical, chemical, and biogeochemical proxies of eventdeposits in the sedimentary archive that allow for confident recognition and dating of past Mw9-class earthquakes vs. smaller earthquakes vs. other driving mechanisms.

2. To explore the spatial and temporal distribution of such event-deposits to investigate alongstrike and time-dependant variability of sediment sources, transport and deposition processes, and stratigraphic preservation.

3. To develop a long-term earthquake record for giant earthquakes.

Platforms, locations and timing

Until the Expedition 386 platforms are confirmed, all timings are provisional.

The mission-specific platform for this expedition will be the JAMSTEC-operated Research Vessel Kaimei, which is equipped with its own 40m giant piston corer. The R/V Kaimei will be mobilised and demobilised at ports to be decided in Japan.

At this time, it is envisaged that the offshore phase of Expedition 386 will take place on the R/V Kaimei for up to 50 days in spring and/or summer of 2020 (Apr-Aug, please watch the Expedition 386 webpage for schedule updates, http://www.ecord.org/expedition386/).

Only a subset of the Science Party will participate offshore. Offshore activities will focus on core recovery, curation, sampling for ephemeral properties, physical properties, and preliminary lithostratigraphy and biostratigraphy (through liner and/or on core catcher samples). The cores will be sectioned offshore, but will not be not opened or split.

Subsequently, an Onshore Science Party (OSP) will be held on board the JAMSTEC-operated Drilling Vessel Chikyu, which will be docked in the Port of Shizuoka, Japan. The OSP is expected to last a maximum of 30 days in the period October to November 2020, the exact length will be dependent on core recovery. During the OSP, the cores will be split and IODP Mission-Specific Platforms Standard Measurements taken. All members of the Science Party must attend the Onshore Science Party. Please see http://www.ecord.org/expeditions/msp/ (and linked pages within) for an overview of Mission Specific Platforms in IODP. Please note that the

Expedition 386 OSP will be held onboard the D/V Chikyu. The link above refers to our usual OSP location at the Bremen Core Repository, located at the University of Bremen in Germany. However, the same OSP principles will still apply. Successful applicants will be invited either as an offshore-onshore participant, or as an onshoreonly participant. Please note that there are no opportunities for offshore-only participation. Expertise sought Opportunities exist for researchers (including graduate students) in all specialties. While other expertise may be considered, specialists in the following fields are required: sedimentology (with special focus on deep-water and hadal trench depositional environments, sediment fabrics, and X-ray computed tomography), event stratigraphy, micropaleontology (including expertise with siliceous microfossils and benthic foraminifera), tephra stratigraphy, paleomagnetics, stratigraphic correlation, organic geochemistry, inorganic geochemistry, physical properties, geophysics, paleoseismology, structural geology, and microbiology. For the offshore phase of the expedition, we are particularly looking for the following fields: sedimentology, micropaleontology, organic geochemistry, inorganic geochemistry, physical properties, event stratigraphy, stratigraphic correlation, geophysics and microbiology.

Volunteer for an IODP Board, Committee, or Panel

The U.S. Science Support Program (USSSP), in association with the International Ocean Discovery Program (IODP), is seeking scientists to participate on a variety of IODP panels, boards, and committees. There are three open calls for participation:

The JOIDES Resolution Facility Board (JRFB) oversees the operations of the JOIDES Resolution, including scheduling expeditions, approving program plans, monitoring the advisory panels to ensure efficient and effective review of drilling proposals, and developing and monitoring policies for data collection, publications and core curation. New JRFB members will serve three-year terms beginning on October 1, 2019. Full terms of reference for the JRFB are available here. USSSP is seeking two senior scientists (both from non-U.S. IODP partners/consortia) to serve on the JRFB.

The IODP Science Evaluation Panel (SEP) is an advisory body of the JRFB, composed of domain experts from IODP member countries. All IODP drilling proposals are first evaluated by the SEP, which is responsible for evaluating the scientific objectives and technical approach of submitted proposals at all stages, and for forwarding ready-to-drill and top-priority proposals to the appropriate Facility Board. New SEP members will serve three-year terms beginning on October 1, 2019. Terms of reference for the SEP can be found here. USSSP is seeking U.S.-based members for SEP, for both the science and site characterization subgroups of the panel. Scientific disciplines particularly needed for SEP this year include paleoclimate & paleoceanography; and in addition, geomicrobiology; sedimentology/stratigraphy; tectonics & geodynamics; hydrates; and marine geophysics.

The U.S. Advisory Committee for Scientific Ocean Drilling (USAC) is the national advisory committee for U.S. participation in IODP and wider issues in scientific ocean drilling. USAC is established through the U.S. Science Support Program (USSSP) to broadly represent the scientific community. This peer-elected group of U.S.-based scientists advises USSSP on shipboard staffing, IODP panel nominations, and education/outreach activities, reviews scientific proposals (e.g., for workshops and pre-drilling activities), and consults on other key elements of the U.S.-based IODP effort. New members will serve three-year terms beginning on October 1, 2019.

Current terms of reference for USAC can be found here.

USSSP is seeking new scientific members for USAC. USSSP seeks expertise in all scientific disciplines relevant to IODP. Scientists interested in volunteering for any of these opportunities should send a cover letter and a two-page CV to usssp@ldeo.columbia.edu by June 24, 2019. Letters should clearly indicate your primary field of expertise, briefly document any previous committee experience, describe your interest in the scientific ocean drilling programs, and identify your preferred panel or committee assignments. Candidates for the JRFB should have an extensive history of participation in scientific ocean drilling. We encourage the involvement of early career scientists on USAC and SEP, as well as those with more experience. For more information, visit usoceandiscovery.org/committees

The deadline for application materials to be sent via email to USSSP is Monday, June 24.

Deep sea cores reveal new insights into breakup and continental drift

It is noteworthy that within the 50-year anniversary of the theory of plate tectonics, scientific ocean drilling can continue to unearth new and fundamental knowledge on how continents part and plates move tectonically. A study based on drill cores from the South China Sea (SCS) obtained by the International Ocean Discovery Program (IODP, http://www.iodp.org/) was recently published in the scientific journal Nature Geoscience (https://rdcu.be/5Syz), confirming predictions by the plate tectonic paradigm regarding the process of continental breakup – the initial step within the plate tectonic cycle. Continue reading
