The International Ocean Discovery Program (IODP) explores Earth’s climate history, structure, mantle/crust dynamics, natural hazards, and deep biosphere as described in the IODP Science Plan Illuminating Earth’s Past, Present, and Future. IODP facilitates international and interdisciplinary research on transformative and societally relevant topics using the ocean drilling, coring, and downhole measurement facilities JOIDES Resolution (JR), Chikyu, and Mission Specific Platforms (MSP). Proposals are being actively sought for all three facilities. The JR is currently scheduled into the beginning 2022. Due to the recent facility renewal, we plan to schedule JR expeditions through the end of 2024. The JR is expected to operate in the Equatorial and North Atlantic, Gulf of Mexico, Mediterranean, Caribbean, and the Arctic in 2021 and 2022, and to complete its circumnavigation with a return to the east Pacific region by 2023, the western Pacific by 2023-2024, and potentially the Indian Ocean by the end of 2024. Proposals for these future operational areas are now needed. MSP expeditions are planned to operate once every other year to recover core from targets that are inaccessible by the other facilities (e.g., shallow water, enclosed seas, inland seas). MSP proposals for any ocean are welcomed. Completely new Chikyu riser proposals (other than CPPs) will not be accepted until after publication of a new post-2023 science plan. We also invite proposals that involve drilling on land and at sea through coordination with the International Continental Drilling Program (ICDP). Investigators are reminded that the interval from the first proposal submission to expedition scheduling is on the order of 4-5 years due to the science and safety review process and required lead time for scheduling, and that adequate site characterization / site survey data are critical for success. Next submission deadline: October 1, 2019.
In July 2019, eighteen international delegates comprising the Science Plan Working Group met to produce a Science Plan Structure and Road Map document highlighting the commonalities in the workshop outcomes and indicating a potential way forward towards a new science plan. This Science Plan Structure and Road Map document is now available for community commenting before it will be discussed at the annual meeting of the IODP Forum in Osaka in September 2019. Now is a key moment in which the IODP community can provide input, in particular to the overall new structure of the proposed science plan. In January and March 2020 there will be two other commenting cycles, when successive drafts of the future science plan will be made available to the community on the IODP.org website. As this is a new plan in support of the future generations of scientific ocean drilling researchers, we especially seek input from early- and mid-career scientists. Please respond before August 26, 2019.
The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 391 Walvis Ridge Hotspot aboard the JOIDES Resolution. Expedition 391 is a scientific ocean drilling project that seeks to understand the geodynamic significance and origin of the Walvis Ridge (WR), a long-lived hotspot trail that began ~132 Ma at the opening of the South Atlantic Ocean. Because of its duration and volcanic expression, WR is the most influential of Atlantic hotspots and is thought to have a deep mantle plume source that can be projected to the edge of the African large low shear wave velocity province (LLSVP), a hypothesized plume generation zone. The hotspot displays long-lived (since ~70 Ma) isotopic zonation, a characteristic thought to originate at the LLSVP edge, and may be the first example of a hotspot split into three isotopically distinct seamount chains. The hotspot interacted with the Mid-Atlantic Ridge (MAR) for most of its early history, producing both the WR and Rio Grande Rise (RGR). Valdivia Bank, a WR plateau, may have formed with the RGR around a microplate, and this added complexity raises questions about simple plume models and the geodynamic implications of this hotspot trail. Opportunities exist for researchers (including graduate students) in all shipboard specialties, including but not limited to sedimentologists, petrologists, micropaleontologists, paleomagnetists, petrophysicists, borehole geophysicists, inorganic and organic geochemists, and microbiologists. The deadline to apply to sail is October 1, 2019.
The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 386 Japan Trench Paleoseismology, aboard a Mission-Specific Platform (MSP) organized by the ECORD Science Operator (ESO) and jointly implemented with the Institute for Marine-Earth Exploration and Engineering (MarE3) within the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). Opportunities exist for researchers (including graduate students) in all specialties.

The workshop Anatomy of a Long-Lived Oceanic Arc: Geology, Geophysics and Geochemistry of the Izu-Bonin-Mariana Arc System and Analogs aims to: (1) review the results of extensive drilling by four recent IODP expeditions; (2) review other (non-drilling) approaches used to study the Izu-Bonin-Mariana (IBM) system; (3) present mantle and ocean floor drilling objectives in other systems and synthesize these with IBM results and goals; (4) make comparisons with arc and ophiolite field analogs around the globe; and (5) identify avenues for future collaborative research. The workshop will involve synthesizing results in the IBM arc system and analogous modern systems and outcrop analogs, a mid-week field trip to examine IBM rocks, and targeted discussion of thematic and geographic areas ideal for collaborative research, synthesis papers, and new research proposals. A number of travel support grants will be available for participants from U.S. institutions and organizations. Support for a limited number of international participants will need to be provided by individuals or IODP member countries. In addition to scientists within the IODP community and early career researchers, we also encourage researchers, including field geologists and modelers, who do not normally participate in IODP projects to apply. Workshop participation is open to U.S. and international researchers and the deadline to apply is May 1, 2019.
Guaymas Basin Tectonics and Biosphere: feedbacks between continental rifting, magmatism, sedimentation, thermal alteration of organic matter, and microbial activity
Authors: Andreas Teske, Daniel Lizarralde, Tobias W. Höfig
The Guaymas Basin in the Gulf of California is a young marginal rift basin characterized by active seafloor spreading and rapid deposition of organic-rich sediments from highly productive overlying waters. The high sedimentation rates in combination with an active spreading system produce distinct oceanic crust where the shallowest magmatic emplacement occurs as igneous intrusion into overlying sediments. The intrusion of magma into organic-rich sediments creates a dynamic environment where tightly linked physical, chemical, and biological processes regulate the cycling of sedimentary carbon and other elements, not only in a narrow hydrothermal zone at the spreading center but also in widely distributed off-axis venting. Heat from magmatic sills thermally alters organic-rich sediments, releasing CO2, CH4, petroleum, and other alteration products. This heat also drives advective flow, which distributes these alteration products in the subsurface and may also release them to the water column. Within the sediment column, the thermal and chemical gradients created by this process represent environments rich in chemical energy that support microbial communities at and below the seafloor. These communities may play a critical role in chemical transformations that influence the stability and transport of carbon in crustal biospheres. Collectively, these processes have profound implications for the exchange of heat and mass between the lithosphere and overlying water column and may determine the long-term fate of carbon accumulation in organic-rich sediments.
The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 389 Hawaiian Drowned Reefs aboard a Mission-Specific Platform (MSP) provided by the ECORD Science Operator. The overall goal of IODP Expedition 389 is to sample a unique succession of drowned coral reefs around Hawaii now at -134 to -1155 m below sea level. 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. 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, 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, physical properties, and petrophysics/downhole logging. The deadline to apply is November 23, 2018.
The International Ocean Discovery Program (IODP) explores Earth’s climate history, structure, mantle/crust dynamics, natural hazards, and deep biosphere as described in the IODP Science Plan Illuminating Earth’s Past, Present, and Future. IODP facilitates international and interdisciplinary research on transformative and societally relevant topics using the ocean drilling, coring, and downhole measurement facilities JOIDES Resolution (JR), Chikyu, and Mission Specific Platforms (MSP). All three IODP facilities are now encouraging new proposals. The JR is currently scheduled into early 2020. The JR is expected to operate in the Equatorial and North Atlantic, Gulf of Mexico, Mediterranean, Caribbean, and the Arctic in 2021 and 2022, and to complete its circumnavigation with a return to the Indo-Pacific region by 2023. Proposals for these future operational areas are strongly encouraged. MSP expeditions are planned to operate once per year on average to recover core from targets that are generally inaccessible by JR and Chikyu. MSP proposals for any ocean are welcomed. To encourage exciting Chikyu expeditions in the future, new pre-proposals for both riser and non-riser operations will be considered. Next proposal deadline: October 1, 2018.
The workshop on Scientific Exploration of the Arctic and North Pacific (SEA-NorP) will focus on the development of new proposals and reinvigoration of existing proposals for scientific ocean drilling in the Northern Pacific, Bering Sea and Western Arctic Ocean region. JOIDES Resolution is scheduled to operate in the Northern Pacific in 2023, so to ensure that the ship is used to best advantage in this region, now is the time to develop drilling proposals that could be linked through regional drilling strategies. The workshop will include discussion of hypotheses that can be tested by scientific drilling in the region, the technology necessary to achieve those goals, ideal sites for drilling based on existing data, and where additional site survey data is needed. Our goal is that multiple proposals will be initiated at the workshop, both for full cruise legs and for shorter, targeted expeditions around the following themes: ocean gateways, geohazards, volatile cycling, ice histories at transition zones, biosphere and climate. Experience in paleoclimate, paleoceanography, sedimentology, geobiology, geophysics, geochemistry, seismology, volcanology, structure and tectonics is sought. We encourage graduate students, early career scientists and those new to IODP to apply, as well as program officers, government representatives, and private sector scientists. A limited number of travel grants will be available. The workshop is open to U.S. and international participants, and the deadline for U.S.-affilitated scientists to apply is June 17, 2018.
We are pleased to announce the release of the JOIDES Resolution Assessment Report, and the accompanying JOIDES Resolution Community Survey Data Report, in support of the National Science Foundation’s request to the National Science Board for the renewal of funding for the JR facility for the next five years. The community overwhelmingly supports the JR and its ability to address high priority objectives of the IODP Science Plan. The Community Survey Data Report documents the responses of 876 of our colleagues, both national and international, and provides significant insights into the IODP community. The Workshop Report reflects the outstanding effort of the 81 attendees of the September 2017 workshop, “Assessment of the JOIDES Resolution in Meeting the Challenges of the IODP Science Plan”. Their tasks included developing expedition results reports in preparation for the workshop, reviewing comments from the Community Survey, and synthesizing the two datasets. The report includes the results of plenary sessions from the workshop that focused on future scientific opportunities that can be addressed in the next five years, as well as discussion surrounding the relationship of the JR to the National Science Foundation’s Sea Change report from 2015, in addition to a list of recommendations and updates for the next five years of JR operations.
Our School of Rock program is a professional development opportunity for formal and informal educators on board or involving the JOIDES Resolution. Teachers will work with scientists and technicians to learn about many aspects of earth science, geology, paleo-oceanography and more done aboard this amazing ship, what we learn from scientific drilling, and how to do the kinds of scientific analyses and lab exercises program-scientists do. This new-found knowledge will help teachers in creating or modifying existing resources for their students in many areas of the science curriculum. This year’s School of Rock is being jointly organized by the United States Science Support Program (USSSP) and the Australia and New Zealand International Ocean Discovery Program Consortium (ANZIC). It will focus on Pacific Rim geology and the science research of the JOIDES Resolution. In our continuing goal to broaden participation in the geosciences, we are especially interested in applicants from diverse backgrounds and/or who serve diverse communities. Apply by April 20, 2018.

Abstract: Geologic processes at convergent plate margins control geochemical cycling, seismicity, and deep biosphere activity in subduction zones and suprasubduction zone lithosphere. International Ocean Discovery Program Expedition 366 was designed to address the nature of these processes in the shallow to intermediate depth of the Mariana subduction channel. Although no technology is available to permit direct sampling of the subduction channel of an intraoceanic convergent margin at depths up to 19 km, the Mariana forearc region (between the trench and the active volcanic arc) provides a means to access materials from this zone.
The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 385 Guaymas Basin Tectonics and Biosphere aboard the JOIDES Resolution. IODP Expedition 385 will core and log a series of sites in the Guaymas Basin to investigate the relationship of tectonics, magmatism, sedimentation, carbon cycling, and microbial activity. The primary objectives are to: (1) explore the physical and chemical gradients along active and extinct fluid pathways associated with sill emplacement; (2) investigate subsurface microbial communities that are sustained by alteration products, in order to determine how efficiently they capture carbon-bearing alteration products; and (3) advance our understanding of the conditions that limit life in the deep biosphere. The expedition will occur from 19 September to 19 November 2019. Additional information about this expedition can be found on the Expedition 385 webpage. Opportunities exist for researchers (including graduate students) in all shipboard specialties, including but not limited to sedimentologists, micropaleontologists, paleomagnetists, inorganic/organic geochemists, microbiologists, petrologists, petrophysicists, and borehole geophysicists.

Authors: Heuer, V.B., Inagaki, F., Morono, Y., Kubo, Y., Maeda, L., and the Expedition 370 Scientists
Abstract: International Ocean Discovery Program (IODP) Expedition 370 explored the limits of the biosphere in the deep subseafloor where temperature exceeds the known temperature maximum of microbial life (~120°C) at the sediment/basement interface ~1.2 km below the seafloor. Site C0023 is located in the protothrust zone in the Nankai Trough off Cape Muroto at a water depth of 4776 m, in the vicinity of Ocean Drilling Program (ODP) Sites 808 and 1174. In 2000, ODP Leg 190 revealed the presence of microbial cells at Site 1174 to a depth of ~600 meters below seafloor (mbsf), which corresponds to an estimated temperature of ~70°C, and reliably identified a single zone of elevated cell concentrations just above the décollement at around 800 mbsf, where temperature presumably reached 90°C; no cell count data was reported for other sediment layers in the 70°–120°C range because the detection limit of manual cell counting for low-biomass samples was not low enough. With the establishment of Site C0023, we aimed to detect and investigate the presence or absence of life and biological processes at the biotic–abiotic transition utilizing unprecedented analytical sensitivity and precision. Expedition 370 was the first expedition dedicated to subseafloor microbiology that achieved time-critical processing and analyses of deep biosphere samples, conducting simultaneous shipboard and shore-based investigations.

Expedition 382 aims to recover 600 m long Late Neogene sedimentary sequences from the Scotia Sea to reconstruct past variability in Antarctic Ice Sheet (AIS) mass loss, oceanic and atmospheric circulation and to provide the first spatially integrated record of variability in iceberg flux from Iceberg Alley, where a substantial number of Antarctic icebergs exit into the warmer Antarctic Circumpolar Current (ACC). This will (a) constrain iceberg flux during key times of AIS evolution since the Middle Miocene glacial intensification of the East Antarctic Ice Sheet, (b) provide material to determine regional sources of AIS mass loss, address interhemispheric phasing of ice-sheet and climate events, and the relation of AIS variability to sea level, (c) provide information on Drake Passage throughflow, meridional overturning in the Southern Ocean, water-mass changes, CO2 transfer via wind-induced upwelling, sea-ice variability, bottom water outflow from the Weddell Sea, Antarctic weathering inputs, and changes in oceanic and atmospheric fronts in the vicinity of the ACC, and (d) provide dust proxy records to reconstruct changes in the Southern Hemisphere westerlies to evaluate climate-dust coupling since the Pliocene, its potential role in iron fertilization and atmospheric CO2 drawdown during glacials. Expedition 382 will also core a sediment drift on the Falkland slope to obtain subantarctic multi-proxy intermediate water depth records of millennial to orbital scale variability in the ocean, atmosphere, nutrients, productivity and ice-sheet dynamics in the SW Atlantic through at least the last 1 Ma. The deadline to apply is October 15, 2017.
The West Antarctic Ice Sheet (WAIS) is largely marine-based, highly sensitive to climatic and oceanographic changes, has had a dynamic history over the last several million years, and if completely melted, could result in a global sea-level rise of 3.3-4.3 m. Expedition 379 will obtain records from the continental shelf and rise of the Amundsen Sea to document WAIS dynamics in an area unaffected by other ice sheets as well and that currently experiences the largest ice loss in Antarctica. The primary objectives include (a) reconstructing the Paleogene to Holocene glacial history of West Antarctica, (b) correlating the Amundsen Sea WAIS-proximal records with global records of ice volume changes and air/seawater temperature proxy records, (c) constraining the relationship between incursions of warm water masses onto the continental shelf and the stability of marine-based ice sheet margins, and (d) reconstructing major WAIS advances onto the middle and outer shelf, including the first ice sheet expansion onto the continental shelf of the Amundsen Sea Embayment and its possible control by the uplift of Marie Byrd Land. U.S.-affiliated scientists interested in participating in these expeditions should apply to sail through the U.S. Science Support Program – visit. The deadline to apply is October 15, 2017.

The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 378 South Pacific Paleogene Climate aboard the JOIDES Resolution. IODP Expedition 378 will investigate the record of Cenozoic climate and oceanography through a drilling transect in the far southern Pacific Ocean. In particular, it will target sediments deposited during the very warm Late Paleocene and Early Eocene including the Paleocene-Eocene boundary, as well as the Eocene-Oligocene transition to investigate how the Eocene earth maintained high global temperatures and high heat transport to the polar regions despite receiving near modern levels of solar energy input. Investigation of the recovered sediments also will constrain the subpolar Pacific climate, oceanographic structure, and biogeochemical cycling of much of the Cenozoic. These sediments will be used to characterize water masses, deep and shallow ocean temperature, latitudinal temperature gradients, the strength of upwelling, and the strength of the zonal winds to study both the atmospheric and oceanic climatic subsystems. The expedition will occur from 14 October through 14 December 2018. Additional information about this expedition can be found on the Expedition 378 webpage. Opportunities exist for researchers (including graduate students) in all shipboard specialties, including but not limited to sedimentologists, micropaleontologists, paleomagnetists, inorganic/organic geochemists, petrologists, petrophysicists, microbiologists, and borehole geophysicists.

Integrated Ocean Drilling Program (IODP) Expedition 347 to the Baltic Sea in 2013 was in line with the IODP Science Plan main research theme “Deep biosphere responses to glacial–interglacial cycles,” addressing questions such as deep biosphere evolution, its biogeochemical processes, and how the postglacial diffusive penetration of conservative seawater ions may alter the chemical composition and microbial physiology in the subseafloor biosphere. Consequently, we tried to enrich indigenous microorganisms at in situ conditions using a broad range of electron acceptors (for fermenters; Fe, Mn, and sulfate reducers; and methanogens), simple and complex carbon substrates (in mixtures or as single compounds), and a wide range of culture conditions (temperature and salinity) to cover varying environmental conditions and metabolic requirements. The most successful were enrichment cultures with a mix of polymeric substrates, which proved to be successful for all samples investigated. Also, iron- and manganese-reducing organisms could be enriched from all sites, whereas nitrate as an electron acceptor did not work well. Methanogenic enrichments were only successful for a few of the samples investigated. In these cases, different monomeric as well as complex substrates were converted to methane, indicating a metabolically versatile indigenous microbial community in the sediments.

The International Ocean Discovery Program (IODP) is now accepting applications for Expedition 380 NanTroSEIZE Frontal Thrust Long-Term Borehole Monitoring System (LTBMS) aboard the D/V Chikyu. The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) Project comprises multiple expeditions over a multi-year period aimed at sampling and instrumenting the up-dip transition into the subduction seismogenic zone. The goal of Expedition 380 is to install an LTBMS in the accretionary toe region near the trough axis at Site C0006, previously drilled during IODP Expeditions 314 and 316. The LTBMS sensors will include: seafloor reference and formation pressure sensors, broadband seismometer, tiltmeters, volumetric strainmeter, geophones, and accelerometers. This will be the third LTBMS installed for the NanTroSEIZE project. The expedition is currently planned for 43 days, beginning on 23 October, sailing on 26 October (after three days of portcall), and finishing on 5 December, 2017. If LTBMS/CORK installation goes ahead of schedule, the ship will return early to port and the expedition will be complete. Additional information about this expedition can be found in the Expedition 380 Call For Participation. Opportunities exist for researchers (including graduate students) to sail on the expedition. Scientific specialties that will likely be required for the shipboard science party include observatory science and downhole logging.

July 10-12, 2017; Narragansett, Rhode Island, USA. Interactions between the land and ocean can provide important feedbacks to climatic evolution and surface processes. The Asian monsoon is an impressive example of these interactions as a major component of Earth’s climate affecting over half of the world population. In the Indian Ocean sector, close interactions between physical and biogeochemical processes with the tectonics of the India-Eurasia collision zone may have controlled both regional and global climate during the Cenozoic. The record of such interactions is best preserved in the ocean and was the target of recent scientific drilling across the region. Land-ocean interactions also play a critical role in modulating climate over Africa where complex interactions between the Indian monsoon and Atlantic occurs. Between 2013 and 2016, a series of IODP expeditions drilled in the Indian Ocean and Western Pacific oceans covering the Asian and Australian monsoon domains and adjacent regions. The goal of this 2.5-day workshop is to review results of the recent regionally-focused scientific drilling expeditions in the Indian Ocean, to propose possible paths for an integrated understanding of the role and response of climate in regulating Indian Ocean hydrology, hydrography, sedimentation, and biogeochemistry, and to synthesize practical lessons for future scheduled and proposed regional IODP drilling campaigns. The workshop is open to U.S. and international participants, and the deadline to apply is April 28, 2017.
The International Ocean Discovery Program (IODP) at Texas A&M University is seeking a qualified individual to oversee curation efforts in support of JOIDES Resolution expeditions and the IODP Gulf Coast Core Repository. The Curator is responsible for oversight of the IODP core and sample collections at the Gulf Coast Repository (GCR) and on JOIDES Resolution expeditions, conservation of the core collection for future use, and supervision of all personnel and activities in the Gulf Coast Repository. The Curator is also expected to develop innovative uses of the core collection and repository. The ideal candidate will have demonstrated experience in a supervisory/management position, including experience with financial, programmatic, reporting, and personnel management. We prefer a background in project management, curation, and familiarity with IODP core curation policies. In addition, the Curator may sail on IODP expeditions if curation support is required. Although the Curator is not expected to sail routinely, the ability to sail is mandatory. At sea, the Curator will be responsible for creating a sampling plan for each site, processing cores as they are received, and training and supervision of the science party in IODP curatorial practice. We will begin reviewing applications on April 1, 2017, but will continue to accept applications until candidates are selected for interviews.
International Ocean Discovery Program (IODP) Expedition 357 successfully cored an east–west transect across the southern wall of Atlantis Massif on the western flank of the Mid-Atlantic Ridge (MAR) to study the links between serpentinization processes and microbial activity in the shallow subsurface of highly altered ultramafic and mafic sequences that have been uplifted to the seafloor along a major detachment fault zone. The primary goals of this expedition were to (1) examine the role of serpentinization in driving hydrothermal systems, sustaining microbial communities, and sequestering carbon; (2) characterize the tectonomagmatic processes that lead to lithospheric heterogeneities and detachment faulting; and (3) assess how abiotic and biotic processes change with variations in rock type and progressive exposure on the seafloor. To accomplish these objectives, we developed a coring and sampling strategy centered on the use of seabed drills—the first time that such systems have been used in the scientific ocean drilling programs. This technology was chosen in the hope of achieving high recovery of the carbonate cap sequences and intact contact and deformation relationships. The expedition plans also included several engineering developments to assess geochemical parameters during drilling; sample bottom water before, during, and after drilling; supply synthetic tracers during drilling for contamination assessment; acquire in situ electrical resistivity and magnetic susceptibility measurements for assessing fractures, fluid flow, and extent of serpentinization; and seal boreholes to provide opportunities for future experiments.
The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on Expedition 376 Brothers Arc Flux aboard the JOIDES Resolution. Expedition 376 will investigate the fundamental, interrelated processes governing subseafloor hydrothermal activity at Brothers volcano, southern Kermadec arc. The primary objectives are to (1) Characterize the subsurface, magma-derived volatile phase for testing models predicting the existence of either a single-phase gas or a two-phase brine-vapor; (2) Explore the distribution of base and precious metals and metalloids at depth as well as the reactions that have taken place during their precipitation along fluid migration pathways to the seafloor; (3) Quantify the mechanisms and extent of fluid-rock interaction, and what this implies for the mass flux of metals and metalloids to the ocean as well as the role of magma-derived carbon and sulfur species in acting as agents for those fluxes; and (4) Assess the diversity, extent, and metabolic pathways of microbial life in an extreme, acidic, and metal-toxic (sub)volcanic environment. The expedition will occur from 5 May through 5 July 2018. Opportunities exist for researchers (including graduate students) in specialties including (but not limited to) sedimentologists, petrologists (igneous/metamorphic/sulfide), structural geologists, paleomagnetists, petrophysicists, borehole geophysicists, microbiologists, and inorganic/organic geochemists. To learn more about the scientific objectives of Exp. 376, life at sea, and how to apply to sail, please join us for a web-based seminar on Wednesday, March 15, 2017 at 1:00 pm EDT (register). U.S.-affiliated scientists interested in participating in this expedition should apply to sail through the U.S. Science Support Program, by visiting http://usoceandiscovery.org/expeditions. The deadline to apply is April 1, 2017.
The Proposal Database System (PDB) is the web-based interface for completing and submitting IODP proposals. PDB offers specific guidance and many proposal components are now created interactively; proponents are advised to begin working with PDB as soon as a proposal is planned. Complete proposal preparation guidance, format requirements, and review policies are explained in the IODP Proposal Submission Guidelines. A Call for Scientific Ocean Drilling Proposals is usually published at least two months in advance of the deadline with specifics about what types proposals are being sought. Proponents are strongly encouraged to contact the Science Operators to discuss platform-specific operational and fiscal constraints before developing proposals. The IODP Proposal Manager has sole authority to accept proposals or grant exceptions to deadlines and policies. Next Proposal Submission Deadline: April 3, 2017.
