Plio‐Pleistocene Antarctic Bottom Water Production in the Ross Sea Reconstructed From Hillary Canyon Levee Turbidites

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Dense shelf water (DSW) formed on Antarctica's continental shelves is a significant precursor for Antarctic Bottom Water (AABW), a critical component of global overturning circulation. We hypothesize that DSW cascades off the central Ross Sea shelf generated density currents that entrained sediment as they flowed down Hillary Canyon, resulting

The power of the past: materializing collective memory at early medieval lordly centres

open access: yesEarly Medieval Europe, Volume 34, Issue 1, Page 34-69, February 2026.
The repurposing of earlier sites and monuments is an enduringly popular theme in early medieval archaeology, but in England it has attracted little interest among Late Saxon and early post‐Conquest studies. From the tenth century, however, an increasingly prevalent pattern is discernible of secular lords locating their power centres in relation to ...

Abnormally Large Magma Flux Does Not Lead to Eruption in Subduction Zone Calderas: The 2022–2023 Episode of Uplift of Aniakchak Crater (Aleutians)

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Observations of ground deformation provide insights on the triggering mechanisms of eruptions. At Aniakchak Crater (Aleutians) InSAR measured ∼ ${\sim} $72 cm of uplift in less than 7 months between 2022 and 2023. The uplift can be explained by the inflation of a point pressure source at a depth of 3.2 km.

Crystal motion measurement by means of satellite techniques [PDF]

open access: yes
A system for monitoring precursory crustal motions is presented. It involves a set of automated corner reflector stations tracked by means of a laser operating in the Geopause satellite. It is possible to range some three times during every Geopause pass

Evaluation of Proposed Earthquake Precursors

open access: yesEos, Transactions American Geophysical Union, 1991
AGU's Evaluation of Proposed Earthquake Precursors presents the first results of a project carried out by the International Association of Seismology and Physics of the Earth's Interior (IASPEI) to evaluate claims about precursors to earthquakes. Only three of 28 nominations were accepted for the Preliminary List of Significant Precursors that IASPEI ...
