Study provides new global accounting of Earth"s rivers
A study led by NASA researchers provides new estimates of how much water courses through Earth's rivers, the rates at which it's flowing into the ocean, and how much both of those figures have fluctuated over time—crucial information for understand.....»»

Philippine settlement submerged by dam reappears due to drought
A centuries-old settlement submerged by the construction of a dam in the northern Philippines in the 1970s has reappeared as water levels drop due to a drought affecting swathes of the country......»»
Drinking water in low-income communities is more likely to be contaminated by "forever chemicals," research finds
PFAS, or forever chemicals, are widespread and more likely to be found in public water systems serving low-income communities and communities of color in New Jersey, according to new research from Northeastern University......»»
Hera asteroid mission"s side-trip to Mars
ESA's Hera asteroid mission for planetary defense will make a swingby of Mars next March, borrowing speed to help reach its target Didymos binary asteroid system......»»
Managing meandering waterways in a changing world
Just as water moves through a river, rivers themselves move across the landscape. They carve valleys and canyons, create floodplains and deltas, and transport sediment from the uplands to the ocean......»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»

Study shows the longer spilled oil lingers in freshwater, the more persistent compounds it produces
Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year, there are many smaller-scale spills into lakes, rivers, and.....»»
Cocaine is an emerging contaminant of concern in the Bay of Santos (Brazil), says researcher
In addition to already known pollutants, the Bay of Santos—a city in the state of São Paulo (Brazil) that is home to the largest seaport in Latin America—has been affected by an emerging contaminant that is now present not only in the water but.....»»
The Mars Sample Return mission has a shaky future, and NASA is calling on private companies for backup
A critical NASA mission in the search for life beyond Earth, Mars Sample Return, is in trouble. Its budget has ballooned from US$5 billion to over $11 billion, and the sample return date may slip from the end of this decade to 2040......»»
A better way to predict Arctic riverbank erosion
Arctic riverbanks are typically resilient, thanks to the power of permafrost. This permanently frozen soil locks in sediment, leading to low erosion rates. But as Arctic river water warms due to climate change, some researchers worry that riverbanks.....»»
If Starship is real, we’re going to need big cargo movers on the Moon and Mars

Shoreline model predicts long-term future of storm protection and sea-level rise
Researchers in North Carolina have created a simulation model to analyze how coastal management activities meant to protect barrier islands from sea-level rise can disrupt the natural processes that are keeping barrier islands above water......»»
Africa"s megacities threatened by heat, floods, disease—action needed to start greening, adapt to climate change
Cities cover just 3% of the planet. But they emit 78% of all global greenhouse gas emissions, absorb 80% of final global energy (what consumers use) and consume 60% of clean drinking water......»»
