Groundwater patches play important role in forest health, water quality

Even during summer dry spells some isolated patches of soil in forested watersheds remain waterlogged These patches act as hot spots of microbial activity that remove nitrogen from groundwater and return it to the atmosphere ... - Read More

Restoring wetlands can lessen soil sinkage, greenhouse gas emissions, study finds

Restoring wetlands can help reduce or reverse soil subsidence and reduce greenhouse gas emissions according to research in California's Sacramento San Joaquin River Delta by Dartmouth College researchers and their colleagues The study which is ... - Read More

Deepwater Horizon spill: Much of the oil at bottom of the sea

Due to the environmental disaster's unprecedented scope assessing the damage caused by the 2010 Deepwater Horizon spill in the Gulf of Mexico has been a challenge One unsolved puzzle is the location of 2 million ... - Read More

Ammonium source in open ocean tracked by researchers

To understand the extent to which human activities are polluting Earth's atmosphere and oceans it's important to distinguish human made pollutants from compounds that occur naturally A recent study co authored by a Brown University ... - Read More

Plump turtles swim better: First models of swimming animals

Hydrogen the most abundant element in the cosmos responds to extremes of pressure and temperature differently Under ambient conditions hydrogen is a gaseous two atom molecule As confinement pressure increases the molecules adopt different states ... - Read More

Past climate change and continental ice melt linked to varying carbon dioxide levels

Scientists at the Universities of Southampton and Cardiff have discovered that a globally warm period in Earth's geological past featured highly variable levels of CO2. Previous studies have found that the Miocene climatic optimum a ... - Read More

Carbonate rocks are unrecognized methane sink

Since the first undersea methane seep was discovered 30 years ago scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse gas methane as part of understanding how the Earth ... - Read More
