How to remove #ghostnets ? 🐟   The NaturDive initiative helps to improve the management of lost nets and protect the fragile ecosystems, in collaboration with the artisanal fishermen of the Cannes, Antibes and Iles de Lérins Natura 2000 zone. The project was supported by BeMed throught the 2022 call for micro-initiatives.   🎯 Objective: Remove at least 10 nets. Each net is located and assessed according to #GhostMed methodology before being removed with the help of the fishermen.   🙌 Impact : 14 fishing nets were removed from depths between 15 and 50m. They represent a total length of 1,740 m and 4,000 m² of rehabilitated seabed, mostly coralligenous.   The organisation members tested prospecting using a ROV, an underwater robot remotely controlled from the surface, but this method proved ineffective. However, a new method was tested: diving prospecting using underwater scooters. This enabled the organisation to survey 11 hectares of seabed between June 2022 and June 2023. Combined with the use of underwater GPS, the prospecting methodology implemented during this initiative is now fully operational and effective.   The objectives are largely achieved and the initiative has contributed to a reduction in underwater waste and to the restoration of marine life. 👏   #plasticpollution #ghostnets #fishingindustry #diving    Foundation for Future Generations

🌊 OPERATION DEEP BLUE LEGACY - Shipwrecks as underwater habitats Did you know that shipwrecks can turn into thriving underwater habitats? These structures provide shelter and living spaces for marine life, transforming into artificial reefs. In our latest video, scientific diver Henning May explains how these submerged ships become oases in the ocean. Watch the video to explore these underwater sanctuaries and learn more about the importance of protecting these historical sites. 🌊🌍 Operation Deep Blue Legacy in partnership with SDSS: The Society for Documentation of Submerged Sites and Ghost Diving. We extend our gratitude to DWS Group‬ for making Operation Deep Blue Legacy possible. 🙏💙 _________________________ #MarineLife #Shipwrecks #ArtificialReefs #Biodiversity #Oceanography #MarineBiology #MarineConservation #MarineLife #MarineResearch #UnderwaterExploration #MarineEcosystems

Nautiterm (Nautical Terms Explained): As The Crow Flies As the crow flies implies the shortest travelling distance between two points. It was a custom to carry crows on board ships. Vessels out of sight of land would release a crow, which would naturally fly towards land, taking the most direct route. Ships would follow the path of the crow, and the lookout platform at the top of the tallest mast became known as the crow’s nest. #hsbtechnical #nautiterm #maritimeindustry #maritimehistory

It seems so effortless for some deep-sea creatures to follow Mark Twain’s counsel to dance like nobody’s watching. This segmented gossamer worm is a Tomopteris that lives its entire life in the Ocean’s Twilight Zone — experiencing neither sun nor seafloor. According to MBARI, they range in size from a few centimeters to over a foot in length, and these pelagic polychaetes possess the ability to spew yellow bioluminescent mucus, they suspect, to deter predators. This hypnotic dancer was spotted during ROV dive operations for our current #SESeamounts expedition. An international team on R/V Falkor (too) is working to describe understudied seamounts that are biodiversity hotspots off the coast of Chile. Their work will likely support critical protections for important area of our global Ocean. #twilightzone #polychaetes #deepsea #oceanexploration #rovsubastian #RVFalkorToo

🌊 **Marine Marvel: The Pygmy Seahorse** 🌊 Did you know that pygmy seahorses are masters of disguise and commitment? These tiny marvels of the ocean spend their entire lives on a single sea fan, moving only within a plate-sized area. Their extraordinary camouflage abilities not only protect them from predators but also highlight the intricate beauty and complexity of marine ecosystems. 🐠✨ This incredible adaptation serves as a reminder of the diverse and delicate life forms that inhabit our oceans. Preserving these underwater wonders is crucial for maintaining the balance and health of our planet's ecosystems. 🌍💙 #MarineBiology #OceanConservation #WildlifeWonder #NatureLovers #Sustainability

Just a reminder that tomorrow, May 23rd, is a full moon. A variety of wildlife often respond to the lunar cycle. For instance, many animals (or lost aliens!) use the light from the full moon for navigation. Migratory birds will use the increased moonlight to help guide them on their journey, just like E.T. So, if you see any strange behavior tomorrow… Assume it's related to the full moon. #DarkSky #ProtectTheNight #DiscoverTheNight #DarkSkyInternational #SaveTheNight #NightMatters #LightPollution #FullMoon

Photographer Piet van den Bemb captured Antarctic humpback whales tracking #Fibonacci spirals in the water using a drone. 🌀 Extraordinary drone footage from Antarctica shows two humpback whales (Megaptera novaeangliae) creating a web of bubbles, as well as the #Fibonacci sequence. Polar photographer Piet van den #Beemd captured the whales working together. The bubble net feeding technique involves the whales diving under bait and then using the bubbles created by their holes to keep the fish close to the surface. According to the #National #Marine #Sanctuary, these whales are called "swallows," meaning they swim to the surface with their mouths open and swallow anything in their path, including fish caught by the bladder. This is a highly complex behavior involving timing, coordination, communication and teamwork, which highlights that whales are intelligent animals. Previous work has shown that this behavior can be learned, meaning that not all populations of humpback whales feed using this method. When Van Den Beemde's images showed this behavior, the structure of the whale's bubble network corresponded to a perfect #Fibonacci sequence, also known as the golden spiral. In geometry, it is a spiral that increases by a factor φ, known as the golden ratio, with every quarter turn of the spiral. It appears to be common in nature, found in pine cones and many vegetables, but it also puzzles scientists when they look for it in the fossil record. “The perfect shape of the Fibonacci spiral made this event incredible,” van den Beemd told Storyful, adding that it was an “absolutely unforgettable” moment. #whales_spiral_Fibonacci
