Throughout the Pacific Northwest, dirt from unpaved roads can clog streams, threatening fish habitats. Scientists have only a murky understanding of how to clear up these turbid waters.
Intermittent rivers are an increasing share of the world's river network, but current models don't include them. One research network is gathering knowledge about these rivers from around the world.
With climate change, some glaciers will melt faster than others, altering the proportions of nutrients in meltwater and changing downstream ecosystems.
A new literature review summarizes the complex role of freshwater in the Arctic and its impact on climate and biogeochemical systems as a whole.
High school and middle school students mingled with scientists from all over the world when they presented their posters at the Joint Aquatic Sciences Meeting.
In a cave accessible only by daredevil divers, extraordinary microbial colonies metabolize nitrogen and iron nutrients and possibly remove pollutants from water.
The Mackenzie River carries the bulk of freshwater flow from North America's tundra to the North Atlantic. But what about the effects of smaller rivers from Canada's Arctic islands?
Laboratory-made perovskite helps explain how water is distributed inside the Earth.
By changing the flow of the river, aquatic plants affect the distribution of nutrients on the riverbed.
