Climate change enhances carbon dioxide flux from lakes

Boreal lakes play a significant role in global carbon cycling. Small and shallow lakes are abundant in northern areas, and they are often biologically active because of the loading of organic matter from the catchments. As ...

How deep-ocean vents fuel massive phytoplankton blooms

Researchers at Stanford University say they have found an aquatic highway that lets nutrients from Earth's belly sweep up to surface waters off the coast of Antarctica and stimulate explosive growth of microscopic ocean algae.

Bottom sediment reveals that climate change flows into lakes

Increasing amounts of dark-coloured carbon compounds that originate from catchment areas flow into the Arctic and northern lakes. They alter resource utilization and community structure of macroinvertebrates, says MSci Henriikka ...

New view of how ocean 'pumps' impact climate change

Earth's oceans have a remarkable natural ability to pull carbon from the atmosphere and store it deep within the ocean waters, exerting an important control on the global climate.

North America's carbon cycle

University of Delaware associate professor Rodrigo Vargas and more than 200 experts from the United States, Canada and Mexico recently unveiled Second State of the Carbon Cycle Report (SOCCR2), a state-of-the-art assessment ...

Ancient wetlands provide new insight into global carbon cycle

Scientists have unearthed and pieced together evidence on more than 1,000 ancient wetland sites from across the globe that are presently covered by fields, forests and lakes. Although vanished from the Earth's surface, these ...
