Glitter is widely used in cosmetics, arts and crafts, fashion, and holiday decorations to add sparkle, but ends up in the ocean. Glitter microplastics disrupt marine biomineralisation of shells and skeletons, and degrade more rapidly in seawater, releasing smaller micro- and nanoplastic fragments.

🔬 "Underview Effect" Discovered: Aquanauts Experience Awe Similar to Astronauts. Northeastern University research identifies a profound psychological shift in individuals living underwater, termed the "underview effect." This mirrors the "overview effect" experienced by astronauts observing Earth from space.

🌊 Enhanced Connection to Marine Life. The study, published in Environment & Behavior, found that 70% of aquanauts reported heightened awe and gratitude, with 64% experiencing increased engagement with their surroundings. This leads to a stronger connection to the specific marine environment.

🧑‍🚀 First Study of Aquanaut Psychology. Lead author Kristen Kilgallen interviewed 14 aquanauts, noting this research is the first to explore cognitive and behavioral changes beyond physiological aspects of extended underwater living and saturation diving.

The world’s coral reefs have lost almost 10% of their hard coral cover over the last four decades. Global assessment finds major bleaching events now strike before recovering corals can mature and reproduce

🐠 Global coral reefs have lost 9.5% of their hard coral cover over four decades (1980-2024), with damaging events now occurring too frequently for recovery.

🌡️ Four global coral bleaching events, driven by marine heatwaves, have been the main cause of loss, with major events now happening every 5-6 years, compared to once a decade previously.

🌊 The fourth global bleaching event (2023-2025) caused the largest decline in hard coral cover in 45 years, and recovery to pre-2016 conditions is increasingly unlikely.

🌿 Macroalgae cover has increased by 44%, hindering coral recovery by taking over spaces needed for new coral to establish, fundamentally changing reef ecosystems.

🌍 New Study Reveals Widespread Plastic Pollution in the Eastern Pacific

🔬 This research presents the first combined evidence of plastic contamination on the deep-sea floor and a six-year coastal time series in the equatorial eastern Pacific.

🌊 A submarine survey by NAUTILE in February 2024 found plastic debris at depths greater than 3,900m, with densities estimated between 0.016 and 0.019 g/m². Common items included degraded fishing gear, bags, and packaging, likely composed of polyethylene, polypropylene, and nylon.

🏖️ Simultaneously, a six-year beach monitoring program (2019–2025) recorded 152.9 kg of debris, with an accumulation rate of 5.7 g/week/m². Similar items found on the beach and at abyssal depths suggest a direct link between coastal and deep-sea pollution.

🐟 Oldest evidence of tuna fishing found in East Timor, dating back ~44,000 years, with ancient fishers in Japan and Korea capturing tunas ~7,000 years ago.

🌊 By 9,000-11,000 years ago, thousands of tuna bones were found in Greece, and a commercial Atlantic bluefin tuna fishery existed in the Mediterranean by 3,000 years ago.

🎣 Indigenous people on North America’s northwest coast had a complex fishery for Pacific bluefin tuna for over 5,000 years, with Southern California Indigenous fishers catching tunas for 6,000 years.
