The Acid Tongue of Climate Change Strikes Our Streams
Clear air policies have led to dramatic reductions in acid rain and improved ecosystem health, but it now appears that climate change could counteract those gains.

Dispersal of River Water by Ocean Eddies and Shallow Ekman Flow
Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.
