Water science news, explainers, and statistics covering freshwater, hydrology, lakes, rivers, groundwater, ice, and Earth’s connected water systems.
A study in Communications Earth & Environment found that invasive cichlids in southern China can shift toward poorer food while keeping key omega-3 fatty acids in their tissues unusually steady. The finding adds a nutritional twist to one of freshwater ecology’s hardest problems, why some introduced fish spread so effectively once they enter a new…

A study in Nature has uncovered a hidden Arctic chain reaction: debris-filled icebergs are carrying rocks away from melting glaciers and dropping them onto the deep seafloor, where they can become rare footholds for bottom-dwelling life. The work links changes in land ice to changes in deep-sea biodiversity hundreds of kilometers from the glaciers where…
NASA Earth Observatory has revealed a striking ocean signal in the equatorial Pacific, where the Sentinel-6 Michael Freilich satellite detected a vast band of higher sea level tied to the developing El Niño. The warm-water feature, known as a Kelvin wave, stretched hundreds of miles and showed how the Pacific can quietly reorganize before weather…
A study in One Earth found that the same large-scale reforestation effort can push global water availability in opposite directions depending on future warming. Under milder warming, forests add a small amount of water to the land surface. Under hotter conditions, the same trees reduce it. Researchers led by Tao Tang, a climate scientist at…
