It's time to zoom in on the boulder star coral with a close-up shot. This image perfectly captures the appearance of this coral when its polyps are not fully extended! Corals, such as this one, can extend their tentacles for actions like feeding and retract them in certain circumstances such as in response to threats. #coral #aquarium #ocean #nature #thereefinstitute #coralreef https://lnkd.in/g5ZPb_T4

Ever wonder what #anemones eat? In this highlight video from #ROVHercules’ exploration of Nafanua Cone on #VailuluuSeamount, we watched in real-time as an #anemone made a meal of a nearby #isopod. Both pink critters were living on the slopes of this active underwater #volcano within the National Marine Sanctuary of American Samoa. #Seaanemones are predators that use their tentacles covered with stinger cells (cnidocytes) containing barbs to catch prey like zooplankton, fish, worms, marine larvae, mussels, and (unfortunately for this crustacean) isopods. Witnessing predation events in the deep sea rarely happens but provides important data to better understand seafloor food chains. https://lnkd.in/ePgYPsZq

Assessing safety in wildfire-prone areas is crucial. This numerical study, focused on Corsica’s WUI, unveils insights into safe separation distances amidst varying terrain and wind conditions. https://lnkd.in/gzYkzijB #WildfireSafety #CorsicaFireRisk

Coming soon: The Vertex II - Living Moss Wall Terrarium. Utilizing a modified version of The Vertex II design, this terrarium features export-grade "CryoMoss" on a modular moss transplantation system, complete with a built-in mechanism to prevent flooding and overwatering. The United States will be the first international location for its launch. Following closely, the Malaysia launch will showcase our domestic-grade CryoMoss, bringing this exciting experience to our local fans. *CryoMoss is our lab cultivated and treated moss that went through multiple quarantine stages for months to remove pests. Export grade variant allows the moss to transport in low humidity / near-dry states to resist unexpected environmental stress during transport, whereas domestic grade features wet samples.

💡 #Highcitedpaper #Xi'an Jiaotong University 🌊 Title: A Cooperative Hunting Method for Multi-AUV Swarm in Underwater Weak Information Environment with Obstacles 🔑 Keywords:  #multiAUV; #cooperativehuntingtask; #obstacleavoidance; #dynamicenvironment 🔗 paper link: https://lnkd.in/gbPdGJf9 📜 Abstract： Cooperative hunting is a typical task that reflects the intelligence level of a swarm. For the complex underwater weak information environment with obstacles, a problem description of the multi-autonomous underwater vehicle (AUV) cooperative hunting task is given, considering the influencing factors, including underwater obstacles, AUV sensing interaction range, and target escape strategy. A hybrid adaptive preference method based on improved artificial potential fields (HAP-IAPF) is proposed. Then the strategies of obstacle avoidance and hunting are designed separately according to the task requirements. The adaptive weight control unit is used to adjust the preference strategy. The multi-AUV cooperative hunting in dynamic obstacle underwater environments under weakly connected conditions are achieved. In order to prove the effectiveness of the proposed algorithm, simulation results compared with the traditional artificial potential field method and the optimized artificial potential field method are given in this paper. The results show that the proposed method is robust and effective in different environments.

Choose "robinia in ground" for the NORNA ARC series and get significant cost savings - up to 21% less than the "cast-in anchors" method. With the “robinia in ground” installation option introduced for the ARC series it is possible to save between 8-21% on the price compared to the “cast-in anchors” option. So, if in ground installation of the ARC playground equipment is an option, the “robinia in ground” is an economical alternative, a standard method used for most of our playground equipment.

Hang on! - Frogfishes, despite their name, do not swim like typical fish. Instead, they employ their modified pectoral fins in unique ways. These fins have evolved into leg-like structures, allowing frogfishes to walk, hop, and even climb on coral reefs or sandy bottoms. By using their fins as limbs, they can move slowly and precisely, camouflaging themselves among the surrounding environment and ambushing unsuspecting prey. - This adaptation of using fins for locomotion highlights the incredible diversity of marine species and their ability to adapt to various ecological niches. Evolution has shaped marine organisms to survive and thrive in different environments, leading to remarkable adaptations like the frogfish's leg-like fins. Such adaptations allow them to exploit their surroundings effectively and increase their chances of survival. - In the vast and dynamic marine world, species continuously evolve to meet the challenges posed by their environment. The frogfish's unique use of fins for movement demonstrates the incredible versatility of marine life, showcasing the endless possibilities for adaptation and evolution in the underwater realm. - #frogfish #ocean #oceanlife #marinelife #marinebiology #scuba #diving #mauritius #uwphoto #uwphotography #uwvideo #macrophoto

🌊 Ever seen ocean eddies in action? Watch how Vestfjorden’s waters swirl, driven by the same forces that shape our weather. 🌪️ Check out this video we’ve put together! It captures the fascinating formation and growth of three large eddies in Vestfjorden during the last half of August 2024. These swirling patterns aren’t just for show – they’re the result of baroclinic instability, the same process that forms high and low-pressure systems in our atmosphere. In the air, these systems can stretch up to 1000 km, but in the ocean, they're much smaller. The eddies you see here are about 30 km across. Pretty cool, right? 🤩 So, why does this matter? In the atmosphere, baroclinic instability helps exchange heat between the equator and higher latitudes. In our example, these eddies are mixing heat and salt across the fjord, playing a key role in its dynamic ecosystem. 🌍 Have a look, and let us know what you think! #oceanintelligence #oceanography #oceanmodeling #sdg14

SURFACE FEEDING BEHAVIOUR OF WHALES Pectoral herding is an innovative tactic for humpback whale foraging. Bubble netting is an advanced and necessary feeding method developed by humpback whales to feed multiple mouths at one time. It is a cooperative feeding method used by groups of humpback whales. This behavior is not instinctual, it is learned; not every population of humpbacks knows how to bubble net feed. Combined with bubble nets, this “pectoral herding” behaviour is believed to better concentrate their prey, thereby increasing the size of each bite. This type of feeding can be done alone or in groups with as many as twenty whales participating at once. Location: Neumayer Channel, Antarctica.
