      In July 2017, a giant iceberg, named A-68, snapped off Antarctica’s Larsen-C ice shelf and began an epic journey across the Southern Ocean. Three and a half years later, the main part of iceberg, A-68A, drifted worryingly close to South Georgia. Concerns were that the berg would run aground in the shallow waters offshore. This would not only cause damage to the seafloor ecosystem but also make it difficult for island wildlife, such as penguins, to make their way to the sea to feed. Using measurements from satellites, scientists have charted how A-68A shrunk towards the end of its voyage, which fortunately prevented it from getting stuck. However, the downside is that it released a colossal 152 billion tonnes of freshwater close to the island, potentially having a profound effect on the island’s marine life.

      It's been speculated that UFO craft exist under the Antarctic ice, and also theorized that UFOs or ET beings have a base under the ice.
      The post 1.5.21 Are UFOs Buried Under Antarctic Ice? appeared first on UAP.News.

      News has recently emerged of global elites (aka cabal) going to Antarctica for a secret meeting. We know from public tweets that Claus Schwab, Founder and Executive Chairman of the World Economic Forum, and Cristina Lagarde, President of the European Central Bank attended a secret Antarctica meeting. Two others present were Brad Garlinghouse and David Schwartz, respectively the President and Chief Technical Officer of Ripple Labs, a computer software company specializing in online payment systems. 

      The original source for the four twitter posts cited above has been found. The four tweets first appeared on the twitter account of XRP the Standard Productions on December 3. 

      The XRP site posts satirical stories, and takes pride in misinforming people. Unfortunately, regarding the four Antarctica tweets, this does cast considerable doubt on their authenticity. 
      However, disinformation is designed to muddy the waters about real events, and something did genuinely happen in Antarctica as one of the four sources, David Schwartz, is actively posting about his recent trip there. So we know one of the four twitter sources did go to Antarctica. Learn more at:exopolitics.org

      I spy with my barreleye, a new Fresh from the Deep! During a dive with our education and outreach partner, the Monterey Bay Aquarium, the team came across a rare treat: a barreleye fish (Macropinna microstoma). 

      MBARI’s remotely operated vehicles Ventana and Doc Ricketts have logged more than 5,600 successful dives and recorded more than 27,600 hours of video—yet we’ve only encountered this fish nine times! 
      The barreleye lives in the ocean’s twilight zone, at depths of 600 to 800 meters (2,000 to 2,600 feet). Its eyes look upwards to spot its favorite prey—usually small crustaceans trapped in the tentacles of siphonophores—from the shadows they cast in the faint shimmer of sunlight from above. 

      But how does this fish eat when its eyes point upward and its mouth points forward? 
      MBARI researchers learned the barreleye can rotate its glowing green eyes beneath that dome (head) of transparent tissue. 

      Aquarist Tommy Knowles and his team were aboard MBARI’s R/V Rachel Carson with our ROV Ventana to collect jellies and comb jellies for the Aquarium’s upcoming Into the Deep exhibition when they spotted this fascinating fish. The team stopped to marvel at Macropinna before it swam away.
