• Ocean acidification may disrupt diatoms' carbon capture and marine food webs

  Our oceans are in trouble, and new research from Flinders University shows how changes in diatoms (microalgae) could further undermine the foundation of aquatic food webs—as well as vital deep-sea carbon capture or sequestration.

  A process known as the biological carbon pump (BCP) moves organic carbon from near the ocean's surface to the ocean floor. That carbon often stays there for hundreds or thousands of years, making the BCP a primary source of carbon sequestration in the oceans. Scientists have thought that…
• Southern Ocean may flip from carbon sink to carbon source under mitigation scenarios

  Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air. While this helps limit extreme weather, sea level rise, ecosystem loss and the risk of triggering…
• Study reveals peatlands may have less capacity to store carbon than predicted

  A new study has revealed that peatlands may break under their own weight before they reach their carbon storage potential.
