Nature Geoscience, Published online: 12 June 2026; doi:10.1038/s41561-026-02004-2 Carbon dioxide hydrates on the seafloor are sustained by the venting of liquid CO2 associated with volcanic activity near Mayotte Island, according to observations from remotely operated vehicles and geochemical analyses.

Nature Geoscience, Published online: 11 June 2026; doi:10.1038/s41561-026-02019-9 Magmatism induced by a mantle plume bearing a relatively high proportion of dense fusible mantle material may have formed the Ontong Java Plateau, the largest extant oceanic plateau, according to thermodynamic modelling.

Nature Communications, Published online: 11 June 2026; doi:10.1038/s41467-026-74313-4 Hg isotopes reveal a negative Δ¹⁹⁹Hg–δ²⁰²Hg relationship restricted to Permian–Triassic crisis intervals, indicating enhanced volcanic Hg loading and providing a framework for tracing Siberian Traps eruptive pulses and environmental change.

1. INTRODUCTION Land cover classification is one of the most important applications of remote sensing, as it helps in monitoring urban expansion, studying vegetation cover, identifying water bodies, and analyzing land use. Many traditional classification methods rely on classifying each pixel independently; however, this approach can produce noisy maps, especially when using Sentinel-2 imagery wi…

The efficient development of deep coal-rock gas resources, exemplified by the pioneering No. 8 coal seam (buried >2000 m) in the Daning-Jixian Block, Ordos Basin, is of strategic importance. This study investigates the critical role of fracturing fluid flowback behavior in determining post-fracturing productivity. Based on systematic analysis of flowback parameters and dynamic data, we evaluate t…

The Penggongmiao complex pluton, located in the Nanling metallogenic belt of South China, provides a critical record of Early Paleozoic (Caledonian) magmatism, but the genesis and mineralization potential of the biotite monzogranite of the pluton have not been constrained. This study presents new whole-rock geochemistry, zircon U–Pb ages, and Sr–Nd–Hf isotopic data for the Penggongmiao biotite mo…

Nature Geoscience, Published online: 09 June 2026; doi:10.1038/s41561-026-01982-7 Increased hydrothermal iron inputs from mid-ocean ridges, triggered by ice-age sea-level falls, supported higher surface primary productivity during the last two glacial terminations, according to proxy records of nutrient consumption in the eastern equatorial Pacific Ocean.

Nature Geoscience, Published online: 09 June 2026; doi:10.1038/s41561-026-02017-x Sediment records from the eastern equatorial Pacific suggest that deglacial increases in hydrothermal iron release from East Pacific Rise volcanism, enhanced by earlier ice-age sea-level fall, boosted phytoplankton nutrient consumption. The findings point to a possible Earth system feedback linking sea level, mid-oc…

Nature Geoscience, Published online: 09 June 2026; doi:10.1038/s41561-026-02001-5 Iron hydride in the Earth’s inner core may exist in a superionic state, according to high-pressure and high-temperature experiments at relevant conditions. Accompanying slow diffusion suggests that the inner core could retain hydrogen on geologic timescales.

Scientists investigating a mysterious drift in Earth’s rotation found an unexpected culprit. New research points to a surprising factor that may have helped shape the planet’s movement.

How to write a point-by-point response to reviewers for Geophysical Research Letters, where the revision must stay inside the 12 publication-unit cap, satisfy the AGU FAIR data policy, and carry the broad-significance bar into the rebuttal.

A pre-submission readiness check for Geophysical Research Letters: the broad-significance bar the editors apply, the 12-publication-unit letter limit and AGU FAIR data rules that trigger fast returns, and a clear submit-or-wait verdict.

Rejected from Geophysical Research Letters? Here are 6 earth and space science alternatives ranked by scope, selectivity, speed, and APC, plus how the AGU transfer cascade routes your paper to its best AGU home.

A collaboration of scientists from NASA and Brazilian research institutions has produced a detailed picture of groundwater change across Brazil. The images reveal significant declines in some of the aquifers that are critical to one of the world’s largest agricultural producers. In the study, published June 3 in Science Advances, researchers used artificial intelligence to […] The post NASA Satel…
