Methodologies for the Automatic Location of Academic and Educational Texts on the Internet [PDF]

open access: yes, 2003
Traditionally online databases of web resources have been compiled by a human editor, or though the submissions of authors or interested parties. Considerable resources are needed to maintain a constant level of input and relevance in the face of ...

3D Variations in Viscosity Reconcile the Strength of the Lower Mantle Inferred From Glacial Isostatic Adjustment and Mantle Convection

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A widely accepted global model of glacial isostatic adjustment (GIA) is based on ICE‐6G ice loading and 1D‐viscosity model VM5a, a viscosity profile which remains at odds with mantle convection constraints such as from geoid modeling. We explore 3D‐viscosity variations in models of GIA and show that a model with lateral viscosity variations ...

Climate and Land‐Use Change May Reshape the Biogeography of Freshwater Crabs Across China

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We employed ensemble species distribution models to investigate how climate and land‐use change will impact habitat suitability for two freshwater crab families (Potamidae and Sesarmidae) across China. Temperature emerged as the dominant driver, with cropland and urban land having strong, family‐specific effects on suitability. Future scenarios predict

Evaluation of glacier mass balance by observing variations in transient snowline positions [PDF]

open access: yes
The author has identified the following significant results. The transient snowline on five outlet glaciers from the Jostedalsbreen ice cap in southwestern Norway could be determined from ERTS image no.

The end stage of barrier estuary infill: Insights from Jack Smith Lake, Southeastern Australia

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Infill model for the saline coastal lake estuary, Jack Smith Lake. Abstract Jack Smith Lake in southeastern Australia is an infilled saline coastal lake, disconnected from the ocean by a foredune barrier. This study explores the Holocene infill history of this estuary in order to understand the end‐stage evolution of barrier estuarine systems with ...

Global-scale estimation of diffuse groundwater recharge : model tuning to local data for semi-arid and arid regions and assessment of climate change impact [PDF]

open access: yes, 2005
Groundwater recharge is the major limiting factor for the sustainable use of groundwater. To support water management in a globalized world, it is necessary to estimate, in a spatially resolved way, global-scale groundwater recharge.

Landsystems of the tropical high Peruvian Andes: Glaciers, lakes, wetlands and water resources in the Cordillera Vilcanota

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
We outline the geomorphological relationships between glaciers, lakes and bofedal wetlands, and the way in which moraines, talus slopes and sandar interact with catchment hydrology in the tropical Andes of Peru. Bofedales are well developed within glacial limits, with glacial processes such as erosion and formation of moraines providing the poorly ...

Geomorphological mapping of the Becca d'Aver deep‐seated gravitational slope deformation (Aosta Valley, Italy) based on multi‐scale and multi‐sensor analysis

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.

Wood restoration results in rapid conversion of a degraded plane‐bed channel, Little River, Washington

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The authors document that wood restoration can rapidly and positively affect a number of geomorphic variables to improve habitat conditions for Pacific salmon. Abstract The loss of instream wood can create a legacy of channel incision that is detrimental to habitat formation.

Climate and Landscape Controls on Dissolved Organic Matter in Wetland‐Dominated Catchments of the Boreal Plains, Canada

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
In the subhumid, wetland‐rich, geologically heterogeneous Boreal Plains region of Canada, we found several controls on stream DOC concentration ([DOC]) and DOM composition: An increase in [DOC] and aromaticity as temperature increases throughout the summer, with temperature trend prevailing over the influence of discharge.
