Long-lived, widespread intraplate volcanism without age progression is one of the most controversial features of plate tectonics. Previously proposed edge-driven convection, asthenospheric shear, and lithospheric detachment fail to explain the ~5000-km-wide intraplate volcanic province from eastern Australia to Zealandia. We model the subducted slab volume over 100 million years and find that slab flux drives volcanic eruption frequency, indicating stimulation of an enriched mantle transition zone reservoir.

- The Arctic's changing climate is causing increased thermokarst formation and erosion, which mobilizes terrestrial organic matter (OM) into nearshore zones.
- A study on Qikiqtaruk - Herschel Island found that disturbances in permafrost led to significant losses of total organic carbon (TOC) and nitrogen (TN), with a decline of up to 77% for TOC after thawing.
- The research suggests that this loss is due to initial dilution from melting ice and degradation processes, while nutrients are introduced into coastal environments, affecting their ecosystems.
