A new study in PLOS One reveals that underwater cave environments leave distinct preservation fingerprints on animal bones, helping scientists reconstruct deposition history and environmental conditions.
Sanya, China, has planted over 68,000 coral polyps in 10 years, restoring the underwater ecosystem near Wuzhizhou Island, increasing coral coverage from 15% to 37% and doubling fish resources.
Marie Tharp, a geologist and cartographer, created the first detailed maps of the ocean floor, revealing its dynamic features and contributing to the theory of plate tectonics, despite facing gender barriers in her field.
Beijing faces calls from a Shanghai Maritime University law professor to enact a dedicated law protecting undersea fibre-optic cables amid rising global threats to critical ocean infrastructure.
Chinese military researchers Shi Guanglei and Shi Haiming warn that unmanned undersea vehicles and the AUKUS pact are lowering barriers to undersea warfare by offering low-cost, scalable capabilities for seabed control.
South Korea and the United States have initiated a joint underwater excavation project off South Korea's eastern coast to locate wreckage and remains of U.S. aircraft lost during the 1950-53 Korean War. The project, running until August 28, focuses on sites in Gangneung and Yangyang.
A study by Lancaster University and the University of Texas found that invasive rats on tropical islands decimate seabird populations, leading to nutrient loss in surrounding coral reefs. This nutrient reduction alters the balance of cryptofauna (tiny fish and invertebrates), favoring invertebrates over fish, and consequently rewires the entire reef food chain, with significant conservation implications.
Bitcoin ETFs, with $16.33B in unrealized losses, face a critical test on Aug. 14 as large investment managers disclose their June 30 positions, revealing whether institutional adoption is durable or merely momentum capital in a regulated wrapper.
The US Coast Guard seeks commercially available systems to detect, track, and disable unmanned underwater vehicles (UUVs) due to a perceived defence gap as China expands its autonomous underwater capabilities.
Russian Navy Commander-in-Chief Admiral Alexander Moiseyev confirms the Navy has a carrier for the strategic Poseidon unmanned underwater vehicle, aligning with the weapon's development program publicly acknowledged by the country's leader.
DEEP's Vanguard, the first US open-ocean subsea habitat in 40 years, is deployed in the Florida Keys National Marine Sanctuary, enabling long-duration underwater research for up to 4 aquanauts, focusing on marine science, human health in extreme environments, and astronaut training.
Nearly 1,500 ships are stranded in the Persian Gulf due to a US-Iran standoff, turning their hulls into breeding grounds for invasive marine species. Scientists warn this biofouling could trigger a 'bioinvasion super-spreader event' upon movement, increasing fuel consumption and posing ecological and economic threats.
Advanced cave diver Will Passos and the Soggy Wombats team are using photogrammetry to create detailed 3D maps of South Australia's Limestone Coast caves, including Mount Gambier's Engelbrecht Cave. This high-tech method updates older maps, aids exploration, and aims to provide public access to these underwater wonders.
The world's largest waterfall, the Denmark Strait overflow, is hidden deep between Greenland and Iceland. Billions of liters of cold, dense seawater sink beneath warmer Atlantic waters every second, forming a crucial part of global ocean currents and climate regulation, which scientists actively study.
Marine scientists observed orcas off Baja California using a cooperative high-speed ramming technique to butcher large sunfish, breaking them into manageable portions for communal feeding and juvenile learning. This behavior, documented in the journal Frontiers in Ethology, highlights the sophisticated hunting strategies of killer whales.
A study in the Netherlands found that a floating solar farm on Bomhofsplas lake may support biodiversity. Researchers observed bird sounds suggesting nesting and found underwater shelters attracted hundreds of fish and thousands of invertebrates, indicating well-designed farms can benefit local ecosystems.
A study at the Bomhofsplas Solar Farm in the Netherlands found bird sounds suggesting nesting under panels and underwater shelters attracting hundreds of fish and thousands of invertebrates. This indicates that well-designed floating solar farms can support biodiversity, reduce water evaporation, and improve panel performance.
A 25-year-old US Masters student, Linnea Bird, is among six interns participating in a program at Eaglehawk Dive Centre to restore Tasmania's rapidly declining giant kelp forests. The project uses a technique developed by the University of Tasmania to reforest under the waves, addressing the impact of warming waters and sea urchin overgrazing.
Kyoto University researchers used passive acoustic monitoring in Wakasa and Aso Bays, Japan, finding dolphins visit the Sea of Japan coast about once every 10 days. This provides vital baseline data for understanding marine life and supporting regional conservation efforts.
Chinese military expert Wang Yunfei stated that the joint participation of Chinese and Russian submarines in the Yellow Sea exercises signifies an exceptionally high level of mutual trust and confidence between the two nations' militaries.
New research from Stockholm University and Project Seagrass indicates that fish from seagrass meadows offer a superior nutritional profile compared to those from coral reefs, potentially aiding millions in coastal East Africa facing malnutrition and poverty.
Over 200 children and counselors were airlifted from Camp Taum Sauk in Lesterville, Missouri, by the National Guard due to historic rainfall and severe flooding. The rescue involved eight Black Hawk helicopters, and families were reunited with their children at a nearby elementary school.
A spearfisher reflects on increased shark encounters, particularly great whites, in Australia and New Zealand. The author notes the humbling experience of facing these apex predators and discusses potential links between surging whale populations and shark numbers, while lamenting polarized public discourse on the issue.
New research indicates seagrass meadows provide fish richer in essential nutrients than those from coral reefs, potentially combating malnutrition in coastal communities along East Africa. The study highlights seagrass as 'food infrastructure' vital for local diets.
