Recent news and analysis on Oceans & Marine Science

Marine science news covering oceanography, coral reefs, fisheries science, sea level rise, and marine ecosystems.

• "Two decades of research show Indonesia's coral reefs are heat-tolerant — but only up to a point"

  This commentary summarizes a new study on Indonesian coral reefs, arguing that while coral cover has remained stable over two decades despite rising sea temperatures, there is a critical heat stress threshold beyond which coral loss accelerates rapidly. The authors contend that stability does not imply safety and that increasingly frequent marine heatwaves could push reefs past recovery.

• "Marine carbon dioxide removal: Our next ocean science, policy and governance frontier?"

  This commentary argues that reaching net-zero emissions is insufficient and that large-scale carbon dioxide removal (CDR) is necessary, focusing on marine CDR as a promising frontier. It contends that land-based CDR has limitations and that ocean-based approaches, such as ocean alkalinity enhancement, require urgent governance and policy development.

• "Aquanauts experience awe-inspiring 'underview effect'"

  This commentary argues that the 'underview effect' experienced by aquanauts living underwater induces awe and strengthens human connectedness to the world, similar to the overview effect in astronauts. It suggests that sharing such experiences could foster greater environmental awareness and connection to the oceans.

• "Asia's marine pledges face credibility test at global ocean conference"

  This commentary argues that Asian governments' marine protection pledges face a credibility test at the upcoming Our Ocean Conference, as implementation and enforcement lag behind ambition. It contends that turning commitments into funded, enforceable action is critical amid threats like warming seas and illegal fishing.
