Boops, hums and farts: The mysterious world of fish communication April 19, 2024 By Frankie Adkins, - Features correspondent A herring swimming (Credit: Getty Images) From mysterious clicking noises in a fish tank in a lab, to humming haddocks and singing toadfish, scientists are discovering the wonder of underwater communication. When you think about how fish communicate with each other, it might conjure little more than a watery silence, punctuated by the odd bubble. In reality, however, "the oceans are alive with sound", says Aaron Rice, a researcher at Cornell University in Ithaca in New York. Clicks, grunts, plops and screeches are just some of the sounds fish use to signal to those around them underwater. Some, such as toadfish, sing beautiful songs to each other, and others, such as herring, communicate using their digestive tracts – more on this later. They use these signals for a variety of reasons: to warn off competitors, sound the alarm and even to woo potential mates. Clues that fish are chattier than we might have given them credit for have floated around since the 4th Century, from the works of Aristotle to whispers from traditional fishing communities, says Rice. But our ability to eavesdrop on fish has been limited by the devices used to record underwater. (Read more about why scientists are eavesdropping on the ocean in this article by Katherine Latham.) Acoustic monitoring has come a long way since the 1930s, and scientists are now using underwater microphones, called hydrophones, to listen in on the marine world. Technology invented in World War Two to scout for submarines has helped us listen to the ways fish talk to one another in the depths of oceans, rivers and lakes. https://lnkd.in/erCryP2Z Francis-Clemens Von Schoenborn-Wiesentheid

🎯 We’re ready for beta-testing! Here’s our mission this summer: to install 100 brand new, free-of-charge oceanographic devices on boats to #monitor the Mediterranean Sea! 🌊 Every day, we have the chance to sail in the great big blue: it gives a stable climate, life, energy, and the greatest joys. Yet, its future depends on how much we will deepen our understanding of its systems, and we can all have a role in this. So, what if your boat is next? 📣  Become an ocean citizen on a mission to accelerate marine research and protect your playground by requesting your device via this form. ➡️ https://lnkd.in/dA_JbXAQ 💡 Learn more about the first plug&play scientific onboard #device for integrated monitoring of #marine climate and meteo. ⬇️ Help us spread the word!

The use of #drones offers a whole new world of posibilities for wildlife scientists and managers all over the world. Their ever increasing capabilities in terms of data capture and processing, autonomy, and affordability, increases the reach and efficiency of ongoing and future research, allowing us to focus on making better informed decissions to preserve species and habitats. At the same time, it's our responsibility to hold ourselves to the highest standards of conduct when deploying this technology, keeping the welfare of the subject and it's surroundings as the top priority, and commiting to minimizing the impact that it may cause by understanding the mechanisms and magnitudes of said impact to different target species.

We've accomplished it! After a challenging and full of challenges final stage of the expedition through Antarctica, we finally completed it. We reached the geographical and official southern poles on December 15, 2023. During their journey, the Ramsey family faced many extreme challenges. Naturally, the most treacherous and dangerous of them were the climatic conditions in the form of roads traversing frozen water bodies or the harsh Antarctic conditions. The couple used solar panels and power generators to replenish the battery during breaks. Proper preparation allowed them to continue the journey even when the vehicle's range decreased to 300 or even 250 kilometers due to extremely low temperatures.

Those mysterious red lights captured by the pilot have intrigued many! According to reports, the photographer is a pilot named Dustin Maggard, who saw and photographed the glow from 31,000 feet over the ocean. The eerie red patches were visible through the clouds over the Atlantic Ocean. While theories abound, one possibility is that the red glow may be due to a unique fishing tactic used by boats fishing for Pacific saury—a type of baitfish. These saury are attracted to the surface of the water by bright red lights, making them easier to catch in the nets of commercial fishing vessels. Interestingly, similar phenomena have been spotted in the past, both by other pilots and even by the International Space Station. So, while it remains a captivating mystery, it seems that the glow might have a practical explanation related to fishing practices in the area¹². 🌟 (1) Pilot Snaps Weird Red Glow Beneath Clouds Unlike Anything He ... - Newsweek. https://lnkd.in/d6mg5pWu.

How the world longest underwater tunnel was built

Sora, Lumiere, et al = game-changing speed of evolution. Prompt: Drone view of waves crashing against the rugged cliffs along Big Sur’s garay point beach. The crashing blue waters create white-tipped waves, while the golden light of the setting sun illuminates the rocky shore. A small island with a lighthouse sits in the distance, and green shrubbery covers the cliff’s edge. The steep drop from the road down to the beach is a dramatic feat, with the cliff’s edges jutting out over the sea. This is a view that captures the raw beauty of the coast and the rugged landscape of the Pacific Coast Highway.

Started at the bottom (of the ocean) and now we’re here… Have we ever told you our origin story? Did you know we began as an environmental business, initially focused on reducing noise from aircraft and marine propulsion systems? It’s true! We developed a unique way to decrease the underwater noise made by marine propellers – PressurePores™. As you might have guessed, we created a series of small angled holes along propeller blades, balancing the different pressures created during rotation. And from there, expanded into sports technology! You see, during this research, we started thinking about other underwater propulsion systems – like oars and paddles – and commissioned a research project that led us to where we are today. And isn’t that the brilliant thing about innovation? Its ability to transcend boundaries, unlocking doors to progress in unexpected places? #oscarpropulsion #oscarpropulsionsport #revolutionarypaddle #revolutionarytechnology #cutbladetechnology #firstofitskind #watersports #SUP #Rowing #kayaking #canoeing #dragonboating #originstory
