The United Nations Environment Programme reports that a drop in ocean pH to 7.95 by 2025 would result in a 30% reduction in coral calcification rates. Survival of Antarctic krill larvae has already been reduced by 25% due to acidification, threatening the survival of penguins, cetaceans and other species. If the world warms by 1.5…

New Caledonia study released in May 2025 showed that 14 metals (e.g., nickel, mercury) and 22 persistent organic pollutants (e.g., pesticide residues) are prevalent in coral reef fish. The larger the fish, the higher the concentration of contaminants, and monthly rainfall and reef area influenced the distribution of organic contaminants and metals, respectively. For example,…

On April 24, 2025, the Trump administration signed an executive order, “Unlocking Critical Minerals and Resources Offshore the United States,” to expedite permitting for polymetallic nodule mining in the Clarion-Clipperton Zone (CCZ) in the eastern Pacific Ocean, with a plan to create 100,000 jobs and gain access to rare earths within 10 years. This zone…

From 9 to 13 June 2025, the third United Nations Oceans Conference will be held in Nice, France, under the theme “Accelerating Action to Mobilize Efforts for the Conservation and Sustainable Use of the Oceans”. The Conference will focus on topics such as the conservation of marine biodiversity, the fight against plastic pollution and sustainable…

Singapore’s technological exploration in the field of ocean carbon removal is centered on mineral-enhanced seawater sequestration, which accelerates the natural process of oceanic absorption of carbon dioxide through the electrolysis of seawater to produce alkaline substances or through the direct addition of minerals, such as peridotite. the first pilot at Singapore’s Tuas Research and Development…

On April 20, the Philippine Navy’s Frigate No. 36 intruded into the territorial waters of Huangyan Island, and its old hull was suspected to be leaking oil under power, resulting in a large oil stain in the nearby waters. The Chinese side followed and monitored the vessel and warned it away, as the oil pollution…

Australia’s Great Barrier Reef has deployed 3D printed coral scaffolds combined with gene editing technology to breed coral species that are resistant to high temperatures, increasing survival rates by 40 percent. The technology is expected to restore 5,000 square kilometers of damaged reef area by 2030 by mimicking the natural reef structure and accelerating the…

Huawei’s Tech4Nature project, in collaboration with the IUCN and the Kenya Wildlife Service (KWS), has realized efficient monitoring of illegal fishing vessels in Kenya’s Kisite-Mpunguti Marine Park through AI technology. Through a three-dimensional monitoring network of AI + 5G + IoT, the system realizes accurate identification of and rapid response to illegal fishing behaviors, reduces…

The EU-funded ESMIC project on the coasts of Latvia and Lithuania found an average of 736 pieces of plastic waste per 100 meters of beach, 92% of which had Vibrio spp. bacteria attached. Laboratory tests showed that these bacteria are highly pathogenic to human skin and the respiratory tract, and can cause sepsis and meningitis.…

The Korean National Cancer Center cultured human cells in the lab with Fukushima nuclear contaminated water and found that carbon – 14 caused a 2.3-fold increase in the probability of DNA double-strand breaks. Despite TEPCO’s claim that “the radiation dose is below the natural background,” scientists warn that low-dose radiation may affect multigenerational health through…
