Seismic structure of the continental margin of French Guiana: implications for the rifting and early spreading of the equatorial Atlantic [PDF]

open access: yes, 2007
Recent studies of passive continental margins suggest that the rifting process produces a variety of structural styles. The along-strike continuity of these rifted margins is punctuated by significant lateral offsets, known as transform margins.

Active Plume, Abandoned Ridge, or Ancient Slab? olivine‐Hosted Melt Inclusions Record the Mantle Melting Conditions Below the East Pacific Revillagigedo Archipelago, Mexico

open access: yesGeochemistry, Geophysics, Geosystems
The voluminous active volcanoes of the Revillagigedo Islands of Socorro and San Benedicto in the east Pacific Ocean exhibit hotspot geochemistry. However, the presence of a deep mantle plume has not been seismologically confirmed.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

A Sea Ice Entrapment Event in the Southern Chukchi Sea: Analysis and Prediction

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Amplified Arctic warming is reducing sea ice cover, which is driving an increase in geopolitical interest in the region as it offers the possibility of reducing shipping times between Asia, Europe, and eastern North America, at the risk of increased ice hazards. Here, we examine the case of the Norseman II research ship that was trapped by sea

Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.

Land Carbon Sink Distribution in Northern Eurasia Is Driven by Climate Change

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract Boreal forests are a major contributor to the global land carbon sink under rising CO2 concentrations and a changing climate. Carbon sink estimates for Northern Eurasia from forest inventories, flux mapping, and remote sensing have moved toward convergence over the past decade, although substantial differences remain. Several bottom‐up and top‐
