A Better Way to Predict Arctic Riverbank Erosion

Rachel Fritts, Science Writer by Rachel Fritts 24 April 202424 April 2024

Permafrost thaw might cause Arctic riverbanks to erode more quickly. But a new study shows why these erosion rates aren’t as dramatic as some scientists feared.

Towards a Unified Framework for Earth, Mars, Titan, and Exoplanets

by Germán Martinez 18 April 202417 April 2024

From a simple set of in situ or synthetic data, a general unified model has been developed to calculate turbulent fluxes and evaporation rates on any rocky body with an atmosphere.

Animals Deserve to Be Included in Global Carbon Cycle Models, Too

by Nathaniel Scharping 16 April 202416 April 2024

Because they are far less plentiful than plants and microbes, animals have typically been excluded from examinations of carbon exchange in the atmosphere. But new research shows they may have a considerable influence on carbon cycle dynamics.

Learning Data Assimilation Without the Help of the Gaussian Assumption

by Stefan Kollet 15 April 202411 April 2024

Major Earth system processes are non-linear and non-Gaussian, and so should be our data assimilation approaches.
