No less than 40 shipwrecks dating back to World War II were discovered off the small island of Lampedusa, Sicily. The wrecks are located 20 to 100 nautical miles off the coast and lie on the sea bottom at 30 to 140 meters and have sunk during the “Battle of the Mediterranean.” Most of these ships are merchant vessels that used to carry cargoes of war supplies, including cannons, bombs, and tanks.Continue reading
The Egyptian-French archaeological mission of the European Institute of Underwater Archeology (IEASM), working in Alexandria has recently discovered a 2000-year-old warship in the sunken city of Thônis-Heracleion, ancient Egypt’s gateway to the Mediterranean. The remains are located in Abu Qir Bay, about two and a half kilometers off the coast.Continue reading
Lake Michigan is the second-largest of the five Great Lakes of North America. Spanning over an area of 22,406 square miles, this large body of water holds an estimate of 1,500 shipwrecks, sprawled across its sandy bottom. Many of these wrecks date back to the 1800s and thanks to the lake’s cold, pristine water, they are essentially intact. Even small items like cutlery and ornaments remain in their original position, unharmed.Continue reading
Despite not having lungs, sharks do have to breathe to survive. They rely on the oxygen from the water, which they harvest as much as they can. It all lies in their gills. Sharks use their gills to extract oxygen from the surrounding water and to get rid of the carbon dioxide in their bodies.Continue reading
One of the most famous rock formations in the world, and an iconic dive site for divers in search of the big stuff, has recently collapsed, only two pillars remaining. The unfortunate event took place in the morning of May 17, 2021. Divers onboard the Galápagos Aggressor III got to witness this historical event, but as of now, there’s no information on the effects of the collapse on the dive site.Continue reading
South African nature documentary, ‘My Octopus Teacher’ has won the Oscar for Best Documentary Feature at the 93rd Academy Awards, an event that honored the best films of 2020 and early 2021.
The Netflix documentary follows the heartwarming story of a diver – filmmaker and naturalist Craig Foster – who befriends a friendly octopus in the cold waters of the Atlantic Ocean in False Bay, South Africa. It is a superb example of beautiful cinematography and offers a unique view of how life is like for the octopuses, these aquatic masters of camouflage.Continue reading
More than 76 years ago, a U.S. Navy destroyer was sunk while attempting to protect an American landing force in the Philippines from multiple Japanese warships during the Battle of Leyte Gulf. The vessel remained undisturbed on the seabed in the Pacific Ocean since 1944 and has only recently been mapped and filmed.
The Fletcher-class destroyer was first discovered in 2019, but its identity remained unconfirmed. Now, thanks to imagery from the undersea technology company Caladan Oceanic, researchers could identify the ship by its hull number, 557. The number was clearly visible on both sides of its bow and corresponded to a warship that was lost at the Battle off Samar.
The ship, named USS Johnston, lies at a depth of 6,500 meters (21,180 feet) in the Philippine Sea. It is about 60 percent deeper in water than the famous RMS Titanic. The lack of oxygen at such great depths helped keep the ship in nearly perfect condition.
Victor Vescovo, owner of Caladan Oceanic and undersea explorer, said: “The wreck is so deep so there’s very little oxygen down there, and while there is a little bit of contamination from marine life, it’s remarkably well intact except for the damage it took from the furious fight.”
What is known is that the USS Johnston was heavily outnumbered by the Japanese fleet. Despite this, the ship showed remarkable courage under such heavy fire. According to the expedition team, the position of the gun turrets seems to point to the fact that they were continuing to fire as the ship went down. Of the crew of 327, only 141 survived. The team laid wreaths before and after the exploratory dives.
The Johnston was captained by Commander Ernest Edwin Evans, of Native American ancestry. Despite having been seriously wounded in the battle, Evans fought bravely until the very end. He was posthumously awarded the Medal of Honor, the first Native American in the U.S. Navy to be awarded this military honor, according to the Naval History and Heritage Command. He was one of only two destroyer captains in WWII to receive the award.
The expedition to the USS Johnston’s wreck site was conducted via Limiting Factor, Vescovo’s manned deep submersible, which has previously been to the deepest point in all five oceans. The sonar data, imagery, and notes taken during the dives have been turned over to the U.S. Navy for further research. The team of undersea explorers is now working with naval historians to shed more light on the WWII battle.
About 71 percent of the Earth’s surface is water-covered. The planet has one global ocean that has been divided into distinct geographic regions. Only 20 percent of it is visible to us. Scientists say that 80 percent of the ocean has never been mapped, explored, or even seen by humans. There’s still so much to learn about what it holds.
The World Register of Marine Species is a comprehensive database managed by hundreds of scientists worldwide. About 2,000 marine species are discovered every year and entered into the register. Earlier this month, researchers contributing to the World Register of Marine Species released their list of 10 favorite marine species that were discovered in 2020.
Without any further ado, here are the fascinating species humans have only recently found and described:Continue reading
Bioluminescence is nothing new. It is found in many marine organisms – some can produce their own light while others host bacteria that do. It is estimated that about 76 percent of ocean animals rely on bioluminescence for communication, camouflage, finding prey, and more.Continue reading
