Rapid Global Oxygen Shifts and Delayed OMZ Response: Pulse and Memory of the Pacific Decadal Oscillation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Natural decadal variability often obscures anthropogenic trends in ocean deoxygenation. Using a global observational oxygen reconstruction (1965–2022), we investigate the role of the Pacific Decadal Oscillation (PDO) in modulating decadal oxygen variability.

Mechanisms of Roadway Instability and Coupled Control Technology for Working Face Passing Through Fault Zones

Energy Science &Engineering, Volume 14, Issue 9, Page 4470-4485, September 2026.
This study mainly explores the instability characteristics of roadways near faults in the working face. Taking the 51104 transportation roadway of the 51104 working face in Shengxin Coal Mine as the main research object, through theoretical analysis, borehole inspection, numerical simulation and on‐site mine pressure observation, the instability ...

Current Status of The Mechanism of Floor Heave in Deep Tunnels

Frontiers in Science and Engineering
Floor heave is an important problem in coal mining. And there has been no consensus on the mechanism of floor heave in deep roadways. Severe floor heave can affect the ventilation, bottom slope and normal use of machinery in the roadway. In this case, analyzing the current situation of the research on the mechanism of floor heave in deep roadway, and ...

Influence of Surface Processes on Intrarift Fault Displacement: 1.38 Million Years of Fault Slip Behavior in the Lake Malawi (Nyasa) Rift

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Surface processes, including hydroclimate variations, affect crustal deformation and fault behavior. These controls are especially important for intrarift faults in continental rift systems, which accommodate substantial strain while experiencing large hydrological load variations beneath rift lakes.

Anatomy of Interannual to Decadal Sea Level Changes in the GECCO3 Ocean Synthesis

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The GECCO3 synthesis is used to infer a dynamically consistent decomposition of sea level changes (variability and trends) on interannual to decadal time scales. Over most parts of the global ocean equatorward of 60° latitude, sea level variability and trends can be explained almost completely by the upper ocean (above 2,000 m) steric ...

On 3‐MMC: A Cathinone I Have Come to Know and Love

Anthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,
