Join ANZIC for this special hybrid RSES Seminar featuring Dr Carmine Wainman, Basin Analyst at Geoscience Australia, as he explores what we’ve learned from IODP Site U1512 in the Bight Basin. The event will be held in the Jaeger 1 Seminar Room at the ANU Research School of Earth Sciences, ANU Acton campus. Join us there at 4pm on Tuesday 11 October and connect with Dr Wainman and the ANZIC team over free pizza and refreshments, or follow the link to attend online.

Biography

Dr Carmine Wainman holds an MSci in Geology from the University of Southampton, UK and a PhD in Geosciences from the University of Adelaide. He currently works at Geoscience Australia since November 2021 as a Basin Analyst in the Advice, Investment Attraction and Analysis Branch in the Minerals, Energy and Groundwater Division and is a Fellow of the Geological Society of London. Carmine has over nine years of industry and research experience both in Australia and the UK including with the RSK Group, Woodside Energy and the University of Adelaide. He participated on the International Ocean Discovery Program Expedition 369 in late 2017, investigating Australian Cretaceous climate and tectonics.

Abstract

Five years ago, the International Ocean Discovery Program Expedition 369 was in the middle of drilling at hole at Site U1512 in the Great Australian Bight. Despite the recovery of a near-complete 700 m succession of silty claystone, the core yielded few secrets as to what it represented, much to the frustration of everyone on board at the time. The core subsequently lost attention with more impressive results emanating from drill sites in the Mentelle Basin. However, subsequent multi-disciplinary analysis of the core has revealed a rich, comprehensive story of marginal marine settings in the southern high latitudes and the response of the Bight Basin to the Cretaceous Greenhouse. 

In this talk, Dr Wainman will share the latest findings of the lower Turonian to upper Santonian silty claystone succession, including what it can tell us about environmental instability in the basin and fluctuating sedimentary provenance as Australia slowly broke away from Antarctica. The talk will also explore life on board the JOIDES Resolution during the two-month expedition and the importance of continuing the scientific ocean drilling program from an ECRā€™s perspective.

Information webinar: 9 September

A special information webinar was held on 9 September for interested parties to learn more about the scientific objectives of this expedition, life at sea, and how to apply to participate.Ā 

 

Background and objectives 

The overall goal of the drilling campaign is to sample a unique succession of drowned coral reefs around Hawaii now at -134 to -1155 m below sea level. As a direct result of Hawaiiā€™s rapid (2.5-2.6/kyr) but nearly constant subsidence, a thick (100-200 m) expanded sequence of shallow coral reef dominated facies is preserved within the reefs. These reefs span important periods in Earth climate history, either not available or highly condensed on stable (Great Barrier Reef, Tahiti) and uplifted margins (Papua New Guinea, Barbados) due to a lack of accommodation space and/or unfavourable shelf morphology. Specifically, these data show that the reefs grew (for ~90-100 kyrs, albeit episodically) into, during and out of the majority of the last five to six glacial cycles. 

Therefore, scientific drilling through these reefs will generate a new record of sea-level and associated climate variability during several controversial and poorly understood periods over the last 500 kyr. 

The project has four major objectives: 

1) To define the nature of sea level-change in the central Pacific over the last 500 kyr, we will construct a new, more complete sea level curve from the drowned Hawaiian reefs that will allow: a) more detailed testing of Milankovitch climate theory predictions and; b) improved constraints on millennial-scale sea-level changes over the last 500 kyr. 

2) To identify critical processes that determine paleoclimate variability of the central Pacific over the last 500 kyr, we will: (a) reconstruct the mean and seasonal/interannual climate variability from massive coral samples; and (b) use these records to investigate how high latitude climate (e.g., ice sheet volume), pCO2, and seasonal solar radiation impact subtropical Pacific climate. This approach can be used to test theoretical predictions of climate response and sensitivity to changes in boundary conditions and climate forcing. 

3) To establish the geologic and biologic response of coral reef systems to abrupt sea-level and climate changes, we will: (a) establish the detailed stratigraphic and geomorphic evolution of the reefs in response to these changes; (b) test ecologic theories about coral reef resilience and vulnerability to extreme, repeated environmental stress over interglacial/glacial to millennial time scales; and (c) establish the nature of living and ancient microbial communities in the reefs and their role in reef building. 

4) To elucidate the subsidence and volcanic history of Hawaii, we will: (a) refine the variation through space and time of the subsidence of Hawaii, and; (b) improve the understanding of the volcanic evolution of the island. 

Timing 

Until the platform and drilling services are confirmed (estimated late summer 2022) all timings are provisional. It is envisaged that the offshore phase of the expedition will last a maximum of 60 days within a window from mid-August to end October 2023, with only a subset of the Science Party participating. Offshore activities will focus on core recovery, curation, sampling for ephemeral properties, microbiology, ancient DNA (aDNA), biostratigraphy, physical properties, preliminary lithostratigraphy (whole core observed at core ends and through plastic liners), and downhole logging. The cores will not be split at sea. 

Subsequently, an Onshore Science Party (OSP) will be held at the MARUM – Center for Marine Environmental Sciences, University of Bremen, Germany, in early 2024 (exact dates to be confirmed), where the cores will be split. The OSP will be a maximum of 4 weeks long, the exact length dependent on core recovery. 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. 

Successful applicants will be invited either as an offshore-onshore participant, or as an onshore-only 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: carbonate sedimentology, corals, sedimentology, paleontology, palynology, organic geochemistry, inorganic geochemistry, structural geology, paleomagnetics, microbiology, ancient DNA (aDNA), physical properties, geophysics, geodynamics, glacial isostatic adjustment, stratigraphic correlation and downhole logging. For the offshore phase of the expedition, we are particularly looking for the following fields: carbonate sedimentology, corals, sedimentology, paleontology, organic geochemistry, inorganic geochemistry, microbiology, ancient DNA (aDNA), physical properties, and petrophysics/downhole logging. 

Where to apply

Applications for participation must be submitted to the appropriate IODP Program Member Office. In your application, please specify if you are interested in participating offshore-onshore or onshore-only. Please note that there is no option to participate offshore-only. 

Applications should reach the appropriate Program Member Office no later than Friday 23 September 2022; candidates shortlisted by the Program Member Offices will be considered by ESO and the Co-chief Scientists in autumn 2022.

SPECIAL CALL – Expedition 395 Reykjanes Mantle Convection & Climate

Special Call for: Physical Properties Specialist, Stratigraphic Correlator/Cyclostratigrapher, Micropaleontologist (nannofossils, diatoms, or radiolarians)

Ā Deadline for applications to ANZIC: 18 July

Reykjanes Mantle Convection and Climate (Expedition 395) will investigate mantle upwelling beneath Iceland, which supports the regional bathymetry and has led to changes in the height of oceanic gateways that control the strength of deep-water flow over geologic timescales. This drilling program contains three objectives: (1) to test contrasting hypotheses for the formation of V-shaped ridges that are the result of interaction between the Mid-Atlantic Ridge and the Iceland plume; (2) to understand temporal changes in ocean circulation and explore connections with plume activity; and (3) to reconstruct the evolving chemistry of hydrothermal fluids with increasing crustal age, varying sediment thickness, and crustal architecture.

Expedition 395 is based on IODP Proposal 892-Full2 (Mantle Dynamics, Paleoceanography and Climate Evolution in the North Atlantic Ocean) and will target the sediments and igneous basement along with downhole logging at sites east of the Reykjanes Ridge. Five sites have already been visited during Expeditions 384 and 395C, in support of Expedition 395. For more information on Expeditions 395 and 395C refer to the Expedition website: https://www.iodp.tamu.edu/scienceops/expeditions/reykjanes_mantle_convection_and_climate.html

The proposed sites intersect V-shaped ridges/troughs pairs and sample the Bjorn and Gardar sediment drifts. Millennial-scale paleoclimate records are contained within rapidly accumulated sediments of contourite drifts in this region. The accumulation rate of the sediments is a proxy for current strength, and the sediments also provide constraints for climatic events including Pliocene warmth, the onset of Northern Hemisphere Glaciation, and abrupt Late Pleistocene climate change. Major, trace and isotope geochemistry of basalts will allow us to observe spatial and temporal variations in mantle melting processes. This combined approach will explore relationships between deep Earth processes, ocean circulation, and climate.

WHO SHOULD APPLY: We encourage applications from qualified scientists (including graduate students) in: (1) physical properties; (2) stratigraphic correlation with an emphasis in cyclostratigraphy; and (3) and biostratigraphers specializing in Neogene nannofossils, diatoms, or radiolarians.

The JOIDES Resolution Science Operator (JRSO) is committed to a policy of broad participation and inclusion, and to providing a safe and welcoming environment for all participants. Good working knowledge of the English language is required.

CALL: Expedition 400 NW Greenland Glaciated Margin

CALL FOR APPLICATIONS

Apply to participate in JOIDES Resolution Expedition 400: NW Greenland Glaciated Margin

12 August to 12 October 2023

The sea-level consequences of anthropogenic climate forcing hinge on how the polar ice sheets respond to global warming. If fully melted the Greenland Ice Sheet has the potential to raise sea-level by >7 m. We know very little of its long-term responses to past climate warming or its role in Earthā€™s climate system. IODP Expedition 400 seeks to address current knowledge gaps in the evolution and variability of the northern Greenland Ice Sheet (NGrIS). The key science objectives are:

(1) to determine maximum and minimum NGrIS configurations during the Pleistocene, from shelf edge glaciation to hypothesized complete ice loss, e.g. during super-interglacials; (2) test the glacial response to pCO2 across the early ice house stage of the middle Cenozoic;  (3) unravel NGrIS erosion history and sedimentary response across major transitions, e.g. Mid-Miocene Transition and Mid-Pleistocene Transition; and (4) reconstruct the Pliocene ocean circulation and northward heat advection through Baffin Bay and potential Arctic ocean gateways.

These objectives will be accomplished by transect-drilling at seven sites to depths of 300-1000 m across the northwest Greenland margin into Baffin Bay. The seven sites will provide a composite stratigraphic succession from Oligocene through the Quaternary. The key targets are: (a) a continous Pleistocene succession representing a deep water channel-drift that forms the distal part of the Melville Bay Trough Mouth Fan; (b) multiple intervals of potential interglacial deposits preserved within intra-shelf depressions; (c) contourite deposits of likely Pliocene age, accessible below a thin glacigenic cover; and (d) a hemi-pelagic basin succession of likely Miocene age exposed by glacial erosion on the inner shelf. Downhole wireline logging is planned for several sites. 

For more information on the expedition science objectives and the JOIDES Resolution schedule see http://iodp.tamu.edu/scienceops/. This page includes links to the individual expedition web pages with the original IODP proposals and expedition planning information.

Application deadline: 1 June 2022

WHO SHOULD APPLY: We encourage applications from all qualified scientists. The JOIDES Resolution Science Operator (JRSO) is committed to a policy of broad participation and inclusion, and to providing a safe, productive, and welcoming environment for all program participants. Opportunities exist for researchers (including graduate students) in many shipboard specialties, including sedimentologists, biostratigraphers (microfossil and palynomorph), organic geochemists (including biomarkers and sedDNA), inorganic geochemists, microbiologists, physical properties specialists/borehole geophysicists (including downhole measurements and stratigraphic correlation), and paleomagnetists. We are especially interested in recruiting scientists keen to engage in multidisciplinary research. Good working knowledge of the English language is required.
