Novel carbon source sustains deep-sea microorganism communities

The first in-depth analyses of dissolved organic carbon (DOC) cycling in the Red Sea highlights the important role of migrating shoals of fish in sustaining deep-ocean microorganisms and potentially the global carbon cycle.

Just five things about GRACE follow-on

Scheduled to launch no earlier than May 22, the twin satellites of the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, a collaboration between NASA and the German Research Centre for Geosciences (GFZ), ...

Small lakes and temporary ponds release CO2 even when dry

Temporary lakes and ponds emit CO₂ even when they are dry, and dry areas emit a larger amount of carbon into the atmosphere. This phenomenon, described now for the first time, could have an impact on the global carbon cycle ...

Southern Ocean drives massive bloom of tiny phytoplankton

Scientists have uncovered the ocean conditions that support a massive summertime bloom of algae that spans 16 percent of the global ocean. Known as the Great Calcite Belt, this dense group of a microscopic phytoplankton, ...

In measuring gas exchange between water and air, size matters

Ponds and lakes play a significant role in the global carbon cycle, and are often net emitters of carbon gases to the atmosphere. However, the rate at which gases move across the air-water boundary is not well quantified, ...
