Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Performance Evaluation of Automated Flood Inundation Mapping Techniques Using Multi‐Temporal Sentinel‐1 SAR Data

open access: yesJournal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT In recent times, the development of algorithms to delineate water surface maps has significantly boosted flood monitoring and mitigation efforts by utilizing dual polarization, multi‐temporal Sentinel‐1 synthetic aperture radar (SAR) data. The Sentinel‐1 mission, with its global land monitoring capability, has been widely employed for SAR ...

Evaluation of LANDSAT MSS vs TM simulated data for distinguishing hydrothermal alteration [PDF]

open access: yes
The LANDSAT Follow-On (LFO) data was simulated to demonstrate the mineral exploration capability of this system for segregating different types of hydrothermal alteration and to compare this capability with that of the existing LANDSAT system ...

Prevalent Greening Conceals the Forgone Ecological Potential of Forest Loss in Southeast Asia

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Across Southeast Asia (SEA), rapid land‐use transformations have extensively replaced natural forests with fragmented plantations and agricultural mosaics. However, quantifying the ecological legacy of this transformation is hindered by persistent cloud cover and the confounding signal of vegetation growth driven by concurrent environmental ...

Assessing Long Term Stability of Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 OLI

open access: yes, 2017
The radiometric calibration stability of Landsat 5 (L5) Thematic Mapper (TM), Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+) and Landsat 8 (L8) Operation Land Imager (OLI) is continuously monitored, trended, and updated using various on-board and vicarious calibration techniques. The on-board calibrators in L5 TM and L7 ETM+ were deemed unreliable

Desertification Risk: Bibliometric Analysis and Future Research Directions

open access: yesLand Degradation &Development, Volume 37, Issue 8, Page 3331-3348, 15 May 2026.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

Habitat Loss Shapes Isotopic Niche Responses of a Didelphid Opossum to Fragmentation in Neotropical Semideciduous Dry Forests of Central Brazil

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Stable isotope analysis indicates that fragmentation and habitat loss in semideciduous dry forests in the Brazilian Cerrado drive trophic niche shifts in Gracilinanus agilis, with potential consequences for its role as a seed disperser. ABSTRACT Habitat loss and fragmentation have notable effects on species' trophic ecology, often most pronounced in ...

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.
