Geodynamic modeling on subduction-spreading interaction and implications for the South China Sea and surrounding regions

open access: yesGeosystems and Geoenvironment, 2023
The convergent subduction zones and the divergent spreading ridges are essential tectonic units that are widely distributed in the South China Sea and the surrounding regions, governing the regional tectonic evolution.

Experimental dissolution of carbonaceous materials in water at 1 GPa and 550°C: Assessing the role of carbon forms and redox state on COH fluid production and composition during forearc subduction of organic matter

open access: yesFrontiers in Earth Science, 2023
Biogenic carbonaceous material (CM) is the main carrier of organic carbon in the subduction zone and contributes to COH fluid production and volcanic arc gaseous emissions.

Response of the mantle to flat slab evolution: Insights from local splitting beneath Peru [PDF]

open access: yes, 2014
The dynamics of flat subduction, particularly the interaction between a flat slab and the overriding plate, are poorly understood. Here we study the (seismically) anisotropic properties and deformational regime of the mantle directly above the Peruvian ...

Bloom compression alongside marine heatwaves contemporary with the Oregon upwelling season

open access: yesLimnology and Oceanography, EarlyView.
Abstract Marine heatwave (MHW) events have led to acute decreases in primary production and phytoplankton biomass in the surface ocean, particularly at the mid latitudes. In the Northeast Pacific, these anomalous events have occasionally encroached onto the Oregon shelf during the ecologically important summer upwelling season.

Tectonic control on great earthquake periodicity in south-central Chile

open access: yesCommunications Earth & Environment
Multi-millennial records of great megathrust earthquakes have highlighted differences in periodicity and recurrence behavior. Understanding tectonic processes responsible for these differences is relevant for fault mechanics and hazard models.

Continental Growth and Recycling in Convergent Orogens with Large Turbidite Fans on Oceanic Crust

open access: yesGeosciences, 2013
Convergent plate margins where large turbidite fans with slivers of oceanic basement are accreted to continents represent important sites of continental crustal growth and recycling.

Subduction Evolution Controlled Himalayan Orogenesis: Implications from 3-D Subduction Modeling

open access: yesApplied Sciences, 2022
Himalayan orogenesis remains enigmatic in terms of Tibetan Plateau geodynamics originating from the Cenozoic India–Eurasian continental collision. India underthrusts below Tibet to the Yarlung–Tsangpo suture, which has been identified as the northernmost

Upper- and mid-mantle interaction between the Samoan plume and the Tonga-Kermadec slabs [PDF]

open access: yes, 2016
Mantle plumes are thought to play a key role in transferring heat from the core\u2013mantle boundary to the lithosphere, where it can significantly influence plate tectonics. On impinging on the lithosphere at spreading ridges or in intra-plate settings,

Autonomous observations enhance our ability to observe the biological carbon pump across diverse carbon export regimes

open access: yesLimnology and Oceanography, EarlyView.
Abstract The expansion of autonomous observation platforms offers vast opportunities for analyzing ocean ecosystems and their role in carbon export. As part of the EXport Processes in the Ocean from RemoTe Sensing campaign, we autonomously measured the productivity regimes in two contrasting end‐member ecosystem states.
