Forgetting and Remembering: Kenneth Cumberland and Soil Erosion in New Zealand, 1940s to 2020s

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 1, March 2026.
The speed and scale of landscape transformation in New Zealand was almost immediately apparent to British geographer Kenneth Cumberland on his appointment to Canterbury University College in 1938. His efforts culminated in the nationally and internationally well‐regarded book ‘Soil Erosion in New Zealand: A Geographical Reconnaissance (1944a)’, which ...

Reaching for Ancestral Heritage: Sakha Collections in the Museums of the World

Museum Anthropology, Volume 49, Issue 1, Spring 2026.
ABSTRACT This paper is devoted to the collections of old Sakha objects produced by Indigenous craftsmen in the north of the Russian Empire and now located in many museums around the world. For several centuries, objects representing Sakha material culture were taken away from their place of origin by explorers, scholars, collectors, and missionaries ...

Temporal Variations of the Oldest Emperor‐Hawaiian Plume Signature Influenced by Interaction With Shallow Mantle Features

Geochemistry, Geophysics, Geosystems
Hawaiian volcanoes 81 Ma (Meiji and Detroit Seamounts) to ∼50 Ma (Kōko Seamount). We show that Emperor seamounts differ from younger Hawaiian Islands in the abundance of isotopically depleted components.

Noble gases confirm plume-related mantle degassing beneath Southern Africa

Nature Communications, 2019
Southern Africa is characterised by unusually elevated topography and abnormal heat flow. This can be explained by thermal perturbation of the mantle, but the origin of this is unclear.

New Insights Into the Cooling of the Oceanic Lithosphere From Surface‐Wave Tomographic Inferences

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract How oceanic plates cool and thicken with age remains a subject to debate, with several thermal models supported by apparently contradictory data. Combining a novel imaging technique that balances resolution and uncertainty with finite‐frequency surface‐wave measurements, we build tomographic model SS3DPacific to revisit the cooling style of ...

Lithospheric controls on melt production during continental breakup at slow rates of extension: Application to the North Atlantic

, 2009
Rifted margins form from extension and breakup of the continentallithosphere. If this extension is coeval with a region of hotter lithosphere,then it is generally assumed that a volcanic margin would follow.

Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

Modeling Anisotropic Signature of Slab‐Induced Mantle Plumes From Thermochemical Piles in the Lowermost Mantle

Geophysical Research Letters
Seismic anisotropy, observed in the lowermost mantle near Large Low‐Shear‐Velocity Provinces (LLSVPs), is likely caused by strong deformation from mantle flow interacting with these regions and/or plume formation.
