Advanced Satellite Fusion Sharpens Tracking of Freshwater Fish Diversity

A framework combines hyperspectral imagery, the Google Satellite Embedding dataset (GSED), environmental DNA (eDNA), and machine learning to predict fish taxonomic richness. By linking biological observations with habitat information, the approach improves accuracy over conventional multispectral methods and offers a scalable, noninvasive pathway for biodiversity mapping, conservation planning, and freshwater surveys.

Synergistic Satellite Carbon-Water Modeling Enhances Global Ecosystem Water-Use Efficiency

Satellite remote sensing reveals how efficiently terrestrial ecosystems convert water loss into carbon gain, but product choice shapes the answer. By benchmarking 64 satellite-derived estimates against flux-tower observations, researchers identified reliable approaches, mapped global patterns from 2001 to 2015.
