Vulnerability of Key Sea Turtle Nesting Beaches to Future Erosion and Sea Level Rise

open access: yesEarth's Future, Volume 14, Issue 3, March 2026.
Abstract Threatened sea turtles rely on sandy beaches for nesting, linking their long‐term survival to global beach availability. However, beaches worldwide are increasingly threatened by anthropogenic stressors and sea level rise (SLR). Reliable vulnerability assessments require understanding beach dynamics across multiple time scales, informed by ...

Capturing Spatial Gradients of Water Color and Clarity in Subtropical Reservoirs During Drought

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Reservoirs have spatial variation in water depth, suspended matter, and biogeochemistry that can influence patterns of water clarity and color. Spatial surveys with sensor‐equipped boats matched in time with satellite image acquisition provide data‐intensive avenues for understanding spatial patterns of optical properties within reservoirs. We

Seasonality, barrage (Farakka) regulated hydrology and flood scenarios of the Ganga River: a study based on MNDWI and simple Gumbel model [PDF]

open access: yesModeling Earth Systems and Environment, 2016
The hydrology of the Ganga River is mainly characterized by high monsoon rainfall and seasonal variability in discharge flow. The study is focuses on both the up and down-streams of Farakka barrage. It has been executed with the help of Modified Normalized Difference Water Index using Landsat satellite images (2014), satellite based discharge data and ...

Impact of Spatial Scale on Optical Earth Observation‐Derived Seasonal Surface Water Extents

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Landsat‐derived products are the most prominent, publicly available sources of large‐scale surface water extent data. However, few studies have assessed the limitations of spatial scale on such products. Here, we mapped seasonal surface water extents utilizing high‐resolution (4.77 m) PlanetScope Basemap imagery and machine learning.
