Reciprocal contributions: Indigenous perspectives and voices on marine‐coastal experiences in the channels of northern Patagonia, Chile

People and Nature, Volume 7, Issue 5, Page 1086-1098, May 2025.
Abstract The recovery of marine ecosystems in areas heavily impacted by fishing and environmental exploitation depends, to some extent, on the sustainable management of resources and should be complemented by cultural traditions, practices and scientific knowledge.

A Search for the Near‐Surface Particulate Layer Using Venera 13 In Situ Spectroscopic Observations

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Whether or not there is a particulate layer in the lowest 10 km of the Venusian atmosphere is still an open question. Some of the past in situ experiments showed the presence of a detached particulate layer, and a few suggested the existence of finely dispersed aerosols, while other instruments supported the idea of no particulate matter in ...

Wood jam mobility in a morphologically active river in northern Chilean Patagonia

Earth Surface Processes and Landforms, Volume 50, Issue 3, 15 March 2025.
This study examined post‐eruption wood jam mobility and channel changes in the Blanco River. Floodplain collapses led to large sediment yields. High wood jam mobility rates were reported. Larger, less compact wood jams persist in stable areas; new and missing jams are smaller and linked to deposition and erosion, respectively.

Mobility of Magmas Within the Earth: Insights From the Elasticity and Transport Properties of Hydrous Albitic Melts

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract The continental crust is produced by the solidification of aluminosilicate‐rich magmas which are sourced from deep below the surface. Migration of the magma depends on the density (ρ) contrast to source rocks and the melt viscosity (η). At the surface, these silica‐rich melts are typically sluggish due to high η > 1,000 Pa s.
