Structural and geomorphic analyses of the Fila Costeña thrust belt in southwest Costa Rica indicate active thrusting within the inner forearc. The Fila Costeña exposes three major thrust faults that imbricate the late Tertiary...
The discovery of a relatively large and complete ptilodictyid bryozoan colony enabled morphometric analysis of astogenetic change from the colony base to the periphery. This enabled us to test the hypothesis that the relative...

Weathering and erosion processes are crucial to Critical Zone (CZ) evolution, landscape formation and availability of natural resources. Although many of these processes take place in the deep CZ (∼10–100 m), direct information...
In this study, we investigate critical zone architecture and seismic anisotropy in Oregon Ridge Park, MD; specifically, the Pond Branch and Baismen Run catchments. Our characterization of critical zone architecture involves...
Reinthaler and others (2019), hereafter Reinthaler 2019, characterize ice extent on 59 volcanoes in Latin America from 1986 to 2015 using Landsat and Sentinel-2 imagery to quantify the impact of climate and eruptions on glacier...
Glaciovolcanic landforms provide global-scale records of paleoenvironmental conditions and yield insights into subglacial eruption processes. Models for the formation of glaciovolcanic ridges, or tindars, are relatively simple,...

In contrast to water and air, ice is the most dynamic enveloping medium and unique environment for volcanic eruptions. While all three environments influence volcanic activity and eruption products, the cryospheric eruption...

Subduction of seamounts and ridges along thinly sedimented convergent margins results in deformation of the overriding forearc. Exposures of newly recognized late Pleistocene, shallow water deposits (i.e., Marenco formation)...
Passage zones are stratigraphic surfaces found in littoral settings separating deposits diagnostic of subaqueous environments from overlying sequences of subaerial deposits. In glaciovolcanic settings, passage zone surfaces are...

Forests are increasingly threatened by climate-change-fuelled cycles of drought, dieback and wildfires. However, for reasons that remain incompletely understood, some forest stands are more vulnerable than others, leaving a...
