Carbonate production in mesophotic and deeper settings on the northern flank of the Sicilian Channel (Terrible and Nameless Banks, Central Mediterranean)
Mesophotic and deeper environments within the Sicilian Channel remain comparatively understudied despite extensive research on shallow carbonate systems. A recent analysis of seafloor samples collected during the R/V Meteor M191 expedition reveals critical factors influencing carbonate production on the Terrible and Nameless Banks. The study demonstrates a transition from phototrophic dominance, driven by coralline algae on the shallower Terrible Bank, to heterotrophic communities—including cold-water corals—in deeper, aphotic zones.
PHYS.Org: Researchers link the mass extinction of once-dominant marine groups to intolerable heat, diminished oxygen in oceans
A recent peer-reviewed study published in *PNAS* establishes a critical link between past marine mass extinctions and periods of extreme ocean warming and oxygen depletion. Researchers have identified intolerable heat and diminished oxygen levels as primary drivers in the decline of once-dominant marine groups. This longitudinal analysis provides further validated evidence supporting the vulnerability of ocean ecosystems to climate change, emphasizing the urgency of understanding and mitigating current climate indicators for effective ocean stewardship.
