I feel like I'm the only one that gets inspired by these videos, but just in case someone else has the motivation to watch a video and feels the joy of tangible progress, I thought I would share anyway.

• Antarctic krill trap vast amounts of carbon from the atmosphere in the ocean floor through their sinking fecal pellets, a new study reports.
• The annual amount is similar to that stored by “blue carbon habitats” such as mangroves, seagrass and salt marshes, highlighting the importance of protecting krill.
• Global warming, melting ice and overfishing pose threats to krill, say researchers who call for new fishing policies to conserve them.

• In the next 50 years, 80% of the Maldives may become uninhabitable, creating human security and livelihood issues of epic proportions for its nearly 400,000 population.
• The rise in ocean temperatures and acidification are leaving severe impacts on coral reefs, affecting both tourism and fisheries in the Maldives and also damaging the country’s critical first line of natural defense.
• Before a 1998 El Niño bleaching event, the archipelago’s coral reefs remained in good condition, but it killed a significant portion of the fragile ecosystem, which continues to be impacted by climate change.
• Among the solutions proposed are the prosperity plans under the Climate Vulnerable Forum (CVF) to help countries overcome debt traps and attract investments through debt for environmental swaps.

Researchers seeking the construction of a massive underwater structure to shield Antarctica’s melting ice sheets from ongoing erosion by seawater could be met with unexpected international challenges, new research reveals.

While scientists debate the logistics of installing a proposed gigantic undersea curtain to protect Antarctic glaciers against melt from warmer seawater they encounter, researchers at Kobe University are looking at a different problem: how the questions of international authority and related security and sovereignty issues might impact such efforts.

The Antarctic Treaty System

(...) In December 1959, the first twelve countries signed the treaty to protect their scientific operations around the Antarctic. Treaty meetings since then have managed to keep their eyes on science, avoiding discussion of territorial disputes and instead pushing for environmental regulations.(...)

After the treaty was adopted last year by the United Nations, more than 100 countries have signified their intent to ratify it, but so far only 14 countries have. Only around 8 percent of the oceans are currently considered protected.

Though most animals, including humans, are born, age, and eventually die, some species can break away from this traditional lifecycle: they seemingly defy age and revert to younger versions of themselves.

The study

On June 26, the Norwegian Ministry of Energy released a proposal for the first licensing round for mining of seabed minerals, setting out areas where companies could eventually apply for licenses. The proposal included a total of 386 blocks, constituting nearly 106,000 square kilometers (40,900 square miles), an area about the size of Iceland, that could potentially be used for mining activities.

The licensing round proposal included a three-month public consultation period, which closed Sept. 26.

Terje Aasland, Norway’s minister of energy, previously stated that he intended to begin awarding mining licenses in the “first half of 2025” with a view to starting commercial extraction in 2030.

The licenses due to be awarded will be exploitation licenses — not exploration licenses.

Kozak conducted infrared spectroscopy and found chemical bonds consistent with polyvinyl acetate,

“It’s funny that no one thought to reach out to a chemist until very late. Everyone had their own opinions and speculation, but no one was really taking a scientific and experimental point of view,” said Kozak.

In our recent journal paper in Nature Geoscience, we show that a thin layer at the ocean surface called the “ocean skin”, a layer thinner than a human hair, increases this ocean CO₂ uptake by about 7%. That sounds like a small difference, but this additional uptake is equivalent to the CO₂ absorbed by the entire Amazon rainforest each year.

As the need to reduce emissions and meet reduction targets ramps up, insights about how the ocean skin works will help scientists understand how the ocean will respond to our emissions.
