| Let’s find out what lies beneath the waves of our world seas where there is so much out there but so little is known.  Let’s explore sea creatures of the deep to volcanoes hidden and active to lost cities buried deep beneath our waves. Maybe there are some famous ship wrecks out there or just some beautiful underwater corals for you to share and enjoy. A little explanation of what we have unearthed for others to read is much appreciated.  So nothing more to say but Let’s take a tour and find some hidden gems.

|  Have you ever heard of a lost city that was submerged in water for centuries? A city that was once a thriving port, rich in history and culture, and was then swallowed up by the sea? If not, then let me introduce you to Heracleion – Alexandria, an ancient city that was rediscovered after being submerged for over a thousand years. Located off the coast of Egypt in the Mediterranean Sea, Heracleion – Alexandria was once a bustling metropolis, a hub for trade, commerce, and religion. It was a city that was steeped in myth and legend, with stories of gods and goddesses, kings and queens, and warriors and merchants. Today, this city has been brought back to life through archaeological excavations, revealing an extraordinary past that was hidden beneath the waves. The rediscovery of Heracleion – Alexandria was a monumental event in the world of archaeology. It was a city that was lost for centuries, and its rediscovery has given us an incredible insight into the ancient world. The first evidence of this city was discovered in the early 2000s, and since then, archaeologists have been working tirelessly to uncover the secrets of this underwater world. The city of Heracleion – Alexandria was founded in the 8th century BC, during the time of the ancient Greeks. It was a city that was dedicated to the worship of the god Heracles, who was believed to have visited the city during his travels. Heracleion – Alexandria was also a major port, and it was the gateway to the rest of Egypt. The city was a hub for trade, and it was a place where merchants from all over the world would come to buy and sell goods. The beauty of Heracleion – Alexandria was unparalleled. The city was home to magnificent temples, palaces, and statues. It was a city that was known for its wealth and prosperity, and it was a place where people would come to worship, trade, and live. The city was also known for its exceptional engineering, with canals, locks, and bridges that made it one of the most advanced cities of its time. As archaeologists began to excavate the city of Heracleion – Alexandria, they discovered an incredible array of artifacts. These artifacts give us an insight into the lives of the people who once lived in this city. The artifacts include pottery, statues, jewelry, and even coins. These artifacts are now on display in museums around the world, allowing us to appreciate the beauty and artistry of the ancient Egyptians. One of the most significant discoveries made during the excavations was the temple of Amun-Gereb. This temple was dedicated to the god Amun, and it was one of the most important religious centers in Egypt. The temple was built in the 6th century BC, and it was one of the largest temples in the world at the time. The temple was decorated with exquisite art and hieroglyphics, and it was a place of great spiritual significance. | |

|  Researchers from Ocean Exploration Trust (founded by oceanographer and Titanic discoverer Robert Ballard) aboard the Exploration Vessel Nautilus found a strange purple blob on the ocean floor off California. Stumped as to what it could be, the scientists joked about it being a spider egg sac or a “tiny momma octopus,” and nicknamed it Blobus purpilis before battling with a crab to retrieve the specimen. It looks kind of like a strange and mesmerizing jellyfish. Research is ongoing as to what the orb is, but it’s hypothesized to be a new species of velutinids, a type of snails. | |

|  Over a century after it sank to the depths of the Weddell Sea off the coast of Antarctica, the lost ship of Anglo Irish explorer Ernest Shackleton has been found. In 1915, the Endurance was trapped by dense pack ice, forcing Shackleton and his crew to make a stunning escape. Now, 107 years later, the wooden vessel has been located, and “it is virtually intact,” said Mensun Bound, the director of exploration at the Falklands Maritime Heritage Trust, which organized the expedition to find it. “The preservation is beyond imagination,” Bound told NBC News by phone Wednesday, adding that the ship’s name could still be seen emblazoned across the stern. “It’s beautiful,” he said. He added that he had “never, ever seen a wreck as bold and beautiful as this,” in the 30 years he has spent working on shipwrecks. “It just doesn’t get any better,” he said. The Weddell Sea's cold temperatures would have played a key role in preserving the ship, said Dan Snow, a British historian whose content platform History Hit partnered with the expedition team to document the discovery. “It is super cold. It’s probably just below zero,” he said. This meant there were “no wood-eating microbes and microorganisms” damaging the vessel, he added. The ship's discovery comes 100 years after Shackleton's death, in 1922. Shackleton's Imperial Trans-Antarctic Expedition set out to achieve the first land crossing of Antarctica. Together with his crew, the explorer embarked on his journey in late 1914, shortly after the outbreak of World War I. He offered to cancel the voyage and put his ship at the disposal of the British government, but he was directed by Winston Churchill, then head of the U.K.'s Royal Navy, to proceed. The Endurance did not reach land, as it became trapped in dense pack ice. After they were stuck in the ice for 10 months, the 28 men on board were forced to eventually abandon ship. They escaped in lifeboats and on foot. Capt. Frank Worsley marked down the coordinates where it sank. The Falklands Maritime Heritage Trust said these played a key role in the discovery of the vessel. The ship was located at a depth of almost 10,000 feet in the Weddell Sea, and it was found within the area the team had initially set on based on Worsley's coordinates.  The team made its discovery weeks after launching the expedition in early February. The wreck will be protected as a historic site and monument under the Antarctic Treaty, ensuring that while it is being surveyed and filmed, it will not be disturbed. The trust had previously said an important goal of its expedition was to “bring the story of Shackleton, his ship and the members of his team to new and younger audiences.” Now, Bound said, the ship’s discovery presents a fresh opportunity “for people to re-explore the whole Shackleton saga.” | |

|  A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa and Saturn's moon Enceladus, and it is speculated that ancient hydrothermal vents once existed on Mars. Hydrothermal vents have been hypothesized to have been a significant factor to starting abiogenesis and the survival of primitive life.  I wrote an essay on these things for a marine biology course in my first year undergrad'... my prof' commented, "This shows a complete and fundamental misunderstanding of everything I told you. Do better."  I am not a marine biologist. | |

|  That's right, long before Microsoft or Apple there was apparently this wonder - the Antikythera mechanism. Discovered sometime between 1900-1901 on the Antikythera shipwreck off the Greek island of the same name, it is believed to the earliest form of a computer. The Antikythera is an anolog computer, that was designed to serve several purposes, including predicting the astronomical positions and eclipses on the calendar. As so much of this period of history's technology has been lost, such advanced use of technology did not reappear in European historical artefacts until the 14th Century. It is now on display at the National Archaeological Museum of Athens. | |

|  Dwarka is one of the best-studied underwater sites in India, and it’s considered as one of the four Dhamas, a sacred place of pilgrimage, in the Hindu religion. Sanskrit literature identities Dwarka as the city once founded by Lord Krishna. Located on the Gujarat’s west coast, in northwestern India, the site is all the more remarkable because it’s thought to be 9,000 years old, which pre-dates known Indian civilization by some 4,000 years. | |

  Discovered by divers in 1901, it took the best part of a century for scientists to figure out exactly what the Antikythera Mechanism was for. As it turns out, it’s an ancient Greek analogue computer. Thanks to x-ray technology, scientists have solved the puzzle of the device, which is about the size of a mantel clock. It was used a sophisticated calendar and computer, mapping the solar and lunar calendars, according to the Smithsonian Magazine. It could even count down the days until the next Olympic Games. | |

|  Nothing like the mysterious “bloop” sound recorded in the South Pacific in 1997 had ever been heard before. It was very loud, low-frequency, and had a unique pattern that made some think it was a newly discovered creature lurking in the depths. (It didn’t help that the sound came from near the location of HP Lovecraft’s fictional sunken city of R’yleh, where a creature called Cthulhu is imprisoned.) Researchers continued to look for the origin of the noise for years, until in 2005 they announced it had been an “icequake,” which occurs when icebergs break off of glaciers. Although that reasoning has been generally accepted, some conspiracy theorists still feel the explanation is a little thin. Last edited by imonline on 2023-06-23 20:57:42 | |

|  For hundreds of years, sailors have reported randomly encountering a strange “milky” cast to the sea as far as the eye can see, but scientists have been unable to explain it—or even know for sure if it was real. In 2006, researchers were actually able to capture a satellite image of a milky sea, and several years later, experiments discovered the glow was likely from bioluminescent bacteria that attract fish in order to be eaten and survive in their guts. But, scientists still aren’t sure how or why the bacteria gather in such huge numbers as to be able to be seen from space. In addition, their glow is continuous, unlike the more commonly seen “dinoflagellate” organisms that produce brief flashes of light. Last edited by imonline on 2023-06-24 13:29:23 | |

|   The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length. The whale has a heart the size of a small car, and during the main feeding season, it consumes around 7936 pounds of krill per day. It is the loudest animal on Earth, even louder than a jet engine -- its calls reach 188 decibels while a jet reaches 140 decibels. The whales' low-frequency whistle can be heard for hundreds of miles and is probably used to attract other blue whales. The Antarctic blue whale is ‘critically endangered’ The blue whale population in Antarctica was drastically reduced by commercial whaling, which started in the southern Atlantic Ocean in 1904. Despite legal protection through the International Whaling Commission in the 1960s, illegal hunting continued until 1972. From about 125,000 individuals in 1926, numbers were reduced to about 3,000 individuals in 2018, which classifies the species as “critically endangered” on the IUCN Red List. A remarkable number of Antarctic blue whales was recently sighted A team of scientists led by the British Antarctic Survey (BAS) was able to share some good news when returning from their recent expedition to the sub-Antarctic island of South Georgia. They counted 55 Antarctic blue whales during their 2020 expedition, which they describe as “unprecedented”. The South Georgia Waters remain an important summer feeding ground. Dr. Jennifer Jackson, a whale ecologist at BAS, says: “After three years of surveys, we are thrilled to see so many whales visiting South Georgia to feed again. This is a place where both whaling and sealing were carried out extensively. It is clear that protection from whaling has worked, with humpback whales now seen at densities similar to those a century earlier when whaling first began at South Georgia.” What is WWF doing? For many years, WWF has worked with the Southern Ocean Commission (CCAMLR) to protect the most critical habitats for iconic species such as whales, penguins, seals, seabirds and their prey – tiny Antarctic krill. In the Southern Ocean, CCAMLR has made a commitment to implement a network of marine protected areas around Antarctica, to protect a range of wildlife impacted by climate change including areas where whales feed on tiny Antarctic krill. WWF works with scientists to provide important information to help governments protect these crucial foraging areas. “Antarctic blue whales are the largest animals on Earth and a spectacular wonder to witness in the wild. They are the true Antarctic giants. However, they are critically endangered, very slowly recovering from the impacts of 20th Century whaling. Now, we are working to protect the important foraging areas for blue whales in the Southern Ocean before it’s too late. This research reaffirms there is still hope,” says Chris Johnson, Global Lead for the Protecting Whales & Dolphins Initiative. | |

|  A potentially immortal jellyfish species that can age backward - the Benjamin Button of the deep - is silently invading oceans, swarm by swarm, a recent study says. Like the Brad Pitt movie character, the immortal jellyfish transforms from an adult back into a baby, but with an added bonus: this sea creature has the Benjamin Button-like ability to revert back to a polyp stage when threatened with starvation or injury, earning it the nickname “immortal jellyfish” About as wide as a human pinky nail when fully grown, the immortal jellyfish (scientific name: Turritopsis dohrnii) was discovered in the Mediterranean Sea in 1883. But its unique ability was not discovered until the 1990s. Scientists still are unsure exactly how its cells are able to regress and regrow, but the immortal jellyfish could hold promise for fighting diseases like cancer in humans. | |

|  The points of the so-called Bermuda Triangle are Miami, Puerto Rico, and Bermuda—but don’t worry if you’ve booked a trip to any of those destinations. Despite the area being known for the unexplained disappearances of ships and planes, there really isn’t any evidence that it’s more dangerous than anywhere else in the world, or that there’s any supernatural phenomenon at work. But, the National Oceanic and Atmospheric Administration (NOAA) does admit there could be scientific reasons for the disappearances, such as the likelihood of hurricanes, rapid changes in weather due to the Gulf Stream, and the numerous islands in the Caribbean that make for tricky navigation. NOAA also acknowledges that the area could possibly mess with navigational tools, making them point true north as opposed to magnetic north; or that “oceanic flatulence,” a burst of methane gas from the sea, could somehow have affected the vessels and planes. | |

|  A glass octopus (Vitreledonella richardi) was spotted by researchers from the Schmidt Ocean Institute in the deep sea of the Central Pacific Ocean. (Image credit: Schmidt Ocean Institute) Researchers from the Schmidt Ocean Institute (SOI) released footage of an elusive glass octopus (Vitreledonella richardi) off the coast of the remote Phoenix Islands, an archipelago located more than 3,200 miles (5,100 km) northeast of Sydney, Australia. The translucent cephalopod was originally discovered during a 34-day expedition of the Central Pacific Ocean onboard the SOI's research vessel Falkor. Onboard scientists spotted the creature using the ROV SuBastian, which spent a total of 182 hours scanning the seafloor during the expedition. Like other "glass" creatures, such as glass frogs and certain comb jellies, glass octopuses are almost completely transparent, with only their cylindrical eyes, optic nerve and digestive tract appearing opaque. | |

|  Scientists in Norway have discovered a volcano at the bottom of the Barents Sea off the coast of Norway. The unusual geological phenomenon was discovered by research vessel Kronprins Haakon with the piloted submersible vehicle ROV Aurora, according to The Arctic University of Norway (UIT). The volcano lies 70 nautical miles south of Bear Island and at a depth of 400 metres, the university further said on its website. This is the second mud volcano that has been discovered within Norwegian waters. "Seeing an underwater mud eruption in real time reminded me how "alive" our planet is," says Professor Giuliana Panieri, expedition leader and Principal Investigator of the AKMA project, which is aimed at collecting information about methane activity in the seabed. Methane is a greenhouse gas responsible for the rising temperature of the planet. The newly-discovered volcano has been named The Borealis Mud Volcano. It rests inside a crater that is 300 metres wide and 25 metres deep and is most likely the result of a catastrophic, natural blow out that abruptly released massive methane just after the last glaciation period (18,000 years ago), said UIT. The volcano has a diametre of 7 metres and is 2.5 metres high, and it continuously emits fluids rich in methane. "We do not exclude the possibility of discovering other mud volcanoes in the Barents Sea. It is only thanks to collaborative team teamwork and advanced technology that these results can be achieved," said Professor Panieri. Researchers said that volcanoes like these are direct windows into the Earth's interior since they erupt predominantly water and fine sediments from depths of several hundred meters to few kilometres providing a window into past environments. UIT said that only one mud volcano exists in Norwegian waters, the Hakon Mosby Mud Volcano, that was discovered in 1995. | |

|  Keep one eye out for Bonnelli’s cock-eyed, which clearly have one eye much bigger than the other. Recent research using Remotely Operated Vehicles (ROVs) has shown that in its natural habitat, these animals are almost always observed in an oblique position with the larger eye facing slightly upward and the smaller eye facing slightly downward. It is thought that the large eye has evolved to break the counter-illumination (a camouflaging technique) of prey items in the water column above the squid, while the small eye is specialized for picking up bioluminescent flashes from predators and prey items in the depths below. Juveniles do not develop the asymmetric eyes and usually inhabit the upper water column between 100 and 200m, while larger individuals are found between 200 and 800 m with most mature specimens being collected from between 1,000 and 2,200m, where light levels are very low. Our specimen was collected at depths between 600-1,000m from the Eastern North Atlantic, in an area known as King’s Trough Flank. It was collected in 1984. | |
