Scientific Reports: Volcanic ash as a driver of enhanced organic carbon burial in the Cretaceous

Volcanic ash as a driver of enhanced organic carbon burial in the Cretaceous Cin-Ty Lee, Hehe Jiang, Elli Ronay, Daniel Minisini, Jackson Stiles, Matt Neal Scientific Reportsvolume 8, Article number: 4197 (2018) doi:10.1038/s41598-018-22576-3 On greater than million year timescales, carbon in the ocean-atmosphere-biosphere system is controlled by geologic inputs of CO2 through volcanic and metamorphic degassing. High atmospheric […]

EPSL: An imbalance in the deep water cycle at subduction zones: The potential importance of the fore-arc mantle

An imbalance in the deep water cycle at subduction zones: The potential importance of the fore-arc mantle Julia Ribeiro and Cin-Ty Lee Earth and Planetary Science Letters Volume 479, 1 December 2017, Pages 298-309 The depth of slab dehydration is thought to be controlled by the thermal state of the downgoing slab: cold slabs are […]

IRESS 2018 – Hoeink

The Quest for Permeability Tobias Hoeink Baker Hughes, a GE company   The only economical way to extract hydrocarbons from low-permeability shale reservoirs is to increase reservoir contact. Horizontal drilling, multi-stage completion, and hydraulic fracturing have proven key technologies in this respect. Yet, there is more to consider when engineering for optimal recovery on the […]

IRESS 2018 – Torres

The life and times of carbon in surface environments Mark Torres, Rice University The geologic cycling of carbon is multifaceted and key to Earth’s long-term habitability. Central to many aspects of the C cycle is the physical transport of terrestrial materials to the ocean and the biogeochemical transformations that occur during transport. Here, we use […]

IRESS 2018 – Minisini

Carbon Cycling, from Volcanoes to Source Rocks, a sedimentary perspective Daniel Minisini, Shell The deep Earth processes (e.g., tectonism, magmatism, volcanism) control the first order shape of the continental margins, the surface Earth processes (e.g., climate, erosion, sediment supply) reshape them through the redistribution of sediment. The interaction between the deep and the surface Earth […]

IRESS 2018-Reinhard

The importance of nutrients for Earth’s carbon cycle Chris Reinhard, Georgia Institute of Technology The global carbon cycle links together the biosphere, planetary climate, and the chemistry of the oceans and atmosphere. The cycling of carbon at Earth’s surface is in turn governed by feedbacks linking it with the oxygen and sulfur cycles, the cycling […]

IRESS 2018-Madof

Gas hydrates in sandy reservoirs interpreted from velocity pull up: Are Mississippi-fan turbidites diffusively charged? Andrew Madof, Chevron   Gas hydrates are recognized as an emerging energy resource and submarine geohazard; they are also thought to be a modulating mechanism on the global organic carbon budget and on past climate change. Although identified primarily from […]

IRESS2018-Yingcai Zheng

Seismic imaging of fractures in reservoirs Yingcai Zheng, University of Houston Commercial production of unconventional resources has introduced many disruptive changes to the energy industry ranging from business aspects to technologies. As of now, about 2/3 of the U.S. oil production is from shale whereas such production was nearly nonexistent a decade ago. Previously, seismic […]

IRESS 2018 – Marie Edmonds

Volcanic CO2 flux into the atmosphere Marie Edmonds (Cambridge University) Volcanoes are a primary mechanism for the transfer of carbon from the interior of Earth (mantle and crust) to the surface environment. Over Earth history, volcanic outgassing has played a central role in setting the atmospheric concentration of CO2. Quantifying the magnitude of the volcanic […]

IRESS2018-Daigle

Multiphase flow in the subsurface carbon cycle from source to sink Hugh Daigle (University of Texas, Austin) Carbon often moves through the subsurface in fluid phases that are distinct from and immiscible with water. These may include methane generated by microbial activity, oil and gas generated from organic source rocks, or carbon dioxide injected into […]
