Shaping Water Management with Planetary Boundaries
A new study uses the planetary boundaries concept to formulate an approach to water management that considers both global and local limits to water cycle modifications.
Linking Hydrology and Biogeochemistry in a Tropical Urban Estuary
Low-lying coastal estuaries are intertwined with tropical cities around the world. Yet little is known about these water bodies, which affect millions of people globally.
Reforestation as a Local Cooling Mechanism
Reforestation has been shown to cool surface temperatures, and a novel study suggests it may also reduce air temperature up to several stories above the ground.
Mapping Nutrient Inputs in the Great Lakes Basin
A new tool links nitrogen and phosphorus applications to land use classifications to better understand where and how much of the nutrients enter watersheds in the U.S. Great Lakes Basin.
Earthquake Statistics Vary with Fault Size
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
A “Super” Solution for Modeling Clouds
Climate models struggle to accurately portray clouds because the models cannot resolve the scales at which clouds form. A new study demonstrates a potential fix for the problem.
Detailed Origins of Sea Spray Revealed, One Droplet at a Time
An energized air-sea interface facilitates exchange between the atmosphere and the ocean. A new study looks at the formation of sea spray, an important component of this exchange.
Fading Air Pollution Reduces Fog in Central Valley
The tule fog in California’s Central Valley is notorious for causing delays and accidents throughout the region; however, a decrease in air pollutants is reducing the fog’s frequency.
Modeling the Subsurface Hydrology of the Greenland Ice Sheet
Firn aquifers—pockets of meltwater beneath the surface of an ice sheet—could have far-reaching impacts on subglacial hydrology, a new study finds.
