Study reveals giant store of global soil carbon

Soil carbon usually refers only to the organic matter component of soils, known as soil organic carbon (SOC). However, soil carbon also has an inorganic component, known as soil inorganic carbon (SIC). Solid SIC, often calcium ...

Enhanced rock weathering results in higher crop yields and improved crop health, study shows

Enhanced rock weathering—a nature-based carbon dioxide removal process that accelerates natural weathering—results in significantly higher first year crop yields, improved soil pH, and higher nutrient uptake, according ...

Even inactive deep-sea 'smokers' are densely colonized by microbial communities, study shows

Under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team that includes researchers ...

How aromatic dissolved organic matter affects organic micropollutant adsorption

Activated carbon is employed for the adsorption of organic micropollutants (OMPs) from water, typically present in concentrations ranging from ng L−1 to μg L−1. However, the efficacy of OMP removal deteriorates considerably ...

Less ice in the Arctic ocean has complex effects on marine ecosystems and ocean productivity, study finds

Over the past 25 years, the amount of summer Arctic sea ice has diminished by more than 1 million square kilometers. As a result, vast areas of the Arctic Ocean are now, on average, ice-free in summer. Scientists are closely ...
