In the 1940s, Americans found a new way to love salt. Not simply for sprinkling on food — we'd acquired a taste for the mineral long before that — but for spreading on roads and sidewalks. Salt became a go-to method to de-ice frozen pavement.
North America's freshwater lakes are getting saltier due to development and exposure to road salt. A study of 371 lakes published today in the Proceedings of the National Academy of Sciences reports that many Midwestern and Northeastern lakes are experiencing increasing chloride trends, with some 44% of lakes sampled in these regions undergoing long-term salinization.
Most of the planet’s freshwater stores are found in the northern hemisphere, a region that is changing rapidly in response to human activity and shifting climatic trends. An international team of scientists analyzed 147 northern lakes and found that many rely on nutrients from tree leaves, pine needles, and other land-grown plants to feed aquatic life.
In coastal communities, the fear of rising sea levels has put climate adaptation and resilience planning at the forefront of shoreline management programs in recent years. But for inland water communities, the impacts of climate change, while perhaps not as obvious as regular coastal flooding events or as scary as sea level rise predictions, are no less real.
Citizen scientists play a vital role in raising awareness about the health of our nation's freshwater resources. Their efforts can help document water clarity and track harmful algal blooms and other indicators of poor water quality instrumental to sound management.
Nestled in the mountainous border between southwestern Macedonia and eastern Albania, Lake Ohrid is a deep, ancient lake. Its waters provide refuge to hundreds of plants and animals that live nowhere else, including seventeen species of fish.
Bolivia's second largest lake, Poopó, has all but dried up, threatening the livelihood of fishing communities and spelling ecological disaster for hundreds of species. The Bolivian government is blaming dry weather spurred by El Niño and a changing climate, but that's not the whole story.
The John H. Martin Award recognizes a paper in aquatic sciences that is judged to have had a high impact on subsequent research in the field. The 2016 Martin Award is for "Carbon dioxide supersaturation in the surface waters of lakes" by Jonathan Cole, Nina Caraco, George Kling and Tim Kratz. Cole et al (1994) documented that lakes are often supersaturated with CO2 and focused attention on inland waters as sources of carbon to the atmosphere.
Climate change is causing the world's lakes to warm, with repercussions for fisheries and freshwater supplies. So reports an ambitious new study, funded by NASA and the National Science Foundation, and recently published in Geophysical Research Letters.
In October 2005, five scientists were marooned on a mountain near Yuan Yang Lake in Taiwan. Dead-set on installing a new batch of water quality sensors, the group had ignored an incoming typhoon that washed out the only road behind them, knocking chunks of pavement the size of a garage down the cypress-covered slopes.
Have you ever wondered how many lakes there are in the world? In an effort to answer this question, an international research team used satellite photos and computerized mapping technology to count up Earth's inland waters. They found about 117 million lakes, covering almost four percent of the planet's non-glaciated surface.
Do you wonder how climate change is affecting lakes? We just need to look across the pond, where scientists and agencies involved in the European Union’s Water Framework Directive have amassed an impressive body of research on the topic.
During a mild July in 1985, a cold front caused algae in Shelburne Pond, a small Vermont Lake, to quickly die back. Decomposing plants stripped the water of available oxygen, smothering aquatic life and causing a massive fish kill.
Although western Lake Erie has become an international poster child for noxious algae, a new study suggests that many of the world’s much smaller, cleaner, and calmer bodies of water are likewise in trouble if greater efforts are not undertaken to keep farm fertilizers and other nutrients out of them.
We live on the blue planet. Some 70% of the Earth’s surface is covered with water, but only 2.5% is classified as fresh. And most freshwater is frozen in polar icecaps, or present in areas that can’t be tapped, such as deep underground aquifers or moisture in soils.
This week the Cary Institute of Ecosystem Studies is hosting eighteen leaders in lake science. They hail from around the world, including Australia, New Zealand, Switzerland, Hungary, Ireland, Taiwan, Argentina, Canada, Ireland, and China.
Many of us eagerly anticipate summer, when fishing, boating and swimming can happen at a favorite lake. This year, though, there may also be a bit of trepidation — what lies ahead for Lake Auburn? Will we see another fish kill?
Most of us are familiar with the idea that we need to reduce carbon dioxide emissions to prevent global warming. Methane is also a problem, and we hear about it much less frequently. But compared to carbon dioxide, methane's impact on climate change is some twenty times more powerful.
On October 10th-14th, more than a hundred scientists from twenty-four countries will meet at Lake Sunapee to discuss freshwater lakes and reservoirs, including what can be done to keep them healthy in the face of population growth and competing demands.
Distant relatives of shrimp, zooplankton are an important food resource for aquatic animals. These free-floating crustaceans are considered one of the foundations of lake food webs, along with their plant counterparts, phytoplankton.
For more than 100 years, New York has been home to one of the world's best-kept conservation secrets. At 6 million acres, the Adirondack Park is the largest protected area in the contiguous United States.
