A new study analyzing 18 years of wave data has revealed that rogue waves are primarily caused by bound-wave asymmetry, challenging previous theories like modulational instability, and highlighting the importance of nonlinear crest sharpening in their formation, which has significant implications for maritime safety and vessel design.
A rare and deadly shark attack off Sydney's Long Reef Beach resulted in the death of a man, prompting a shark hunt and beach closures, with authorities analyzing the incident and increasing safety measures during peak shark season.
A 63-year-old American tourist was severely injured in a shark attack while spearfishing near Big Grand Cay in the Bahamas, highlighting the region's rare but notable shark incidents. The man was airlifted to the U.S. for treatment, amid a series of recent shark attack cases in the Bahamas involving tourists. Despite the high-profile incidents, shark attacks remain extremely rare in the area.
A 63-year-old American tourist was severely injured in a shark attack while spearfishing near Big Grand Cay in the Bahamas, an area with a high but still rare incidence of shark attacks, with only 34 confirmed cases over 400 years. The Bahamas has experienced several recent shark-related incidents involving tourists, highlighting ongoing marine safety concerns.
A 75-foot ferry operated by Atlantis submarine ran aground at Kewalo Basin Harbor in Honolulu on August 9, with no injuries or fuel leaks reported. The vessel is under US Coast Guard jurisdiction, and authorities are working to safely remove and inspect it before returning it to service.
The U.S. Coast Guard investigation revealed that the 2023 Titan submersible tragedy, which resulted in five deaths, was preventable due to OceanGate CEO Stockton Rush's repeated neglect of safety warnings, inadequate design and maintenance, and a toxic workplace culture, highlighting the need for stronger oversight in submersible operations.
The US Coast Guard released a detailed investigation report on the Titan submersible tragedy, citing design flaws, inadequate maintenance, and regulatory gaps as key factors in the implosion that killed five people during a Titanic dive, and proposing 17 safety recommendations to improve oversight and international cooperation.
A large cargo ship carrying 3,000 vehicles sank in international waters off Alaska after a fire and heavy weather, with no injuries reported but ongoing pollution monitoring efforts.
A Singapore-flagged cargo ship, MV Wan Hai 503, caught fire off the coast of Kerala, India, resulting in 18 crew members rescued and 4 missing, with concerns about an oil spill and debris drifting towards the coast, amid ongoing rescue efforts and environmental alerts.
In November 2020, a buoy off British Columbia recorded the Ucluelet wave, a 58-foot rogue wave, considered the most extreme ever due to its relative size. Such waves, occurring once every 1,300 years, pose significant maritime dangers. Recent studies highlight wind's role in rogue wave formation, emphasizing the need for improved marine safety measures. As climate change may increase wave heights, integrating wind dynamics into predictive models is crucial for enhancing safety and decision-making in marine operations.
A 46-year-old man was bitten by a shark while swimming in Del Mar, leading to significant but non-life-threatening injuries. Del Mar lifeguards have closed beaches for swimming and surfing for one mile in both directions from the incident site until Tuesday morning. The City of Del Mar is working with experts from the Shark Lab at California State University Long Beach to manage the situation. This is the second shark attack in Del Mar in about a year and a half.
In November 2020, a massive rogue wave off the coast of British Columbia reached a height of 17.6 meters (58 feet), making it the most extreme rogue wave ever recorded at the time. Rogue waves, defined as waves more than twice the height of surrounding waves, were once considered nautical folklore until the first confirmed sighting in 1995. Scientists are still studying how these waves form and are concerned that wave heights in the North Pacific may increase with climate change. Understanding rogue waves is crucial for marine safety and coastal communities.
