Mysterious holes on the Pacific seafloor remain unexplained after sediment tests

PC: National Oceanic and Atmospheric Administration Scientists exploring the deep sea have discovered unusual patterns of holes in seafloor sediment, but their origin remains unknown despite closer examination and sediment sampling. NOAA’s Voyage to the Ridge 2022 expedition observed the formations at depths of about 2,540 metres, with further sightings between 1,440 and 1,500 metres. Researchers documented holes in 2004 along the northern Mid-Atlantic Ridge, north of the Azores. Researchers Michael Vecchione and Odd Aksel Bergstad later examined these earlier observations in a scientific paper, suggesting that the raised sediment could indicate excavation by organisms. Neither investigation established what created the holes, leaving their origin an unresolved question in deep-sea research.What did scientists discover about the mysterious holes on the Pacific seafloorAccording to the National Oceanic and Atmospheric Administration, during Dive 04 of the second Voyage to the Ridge 2022 expedition, scientists observed several sets of holes in seafloor sediment at a depth of approximately 2,540 metres (1.6 miles). NOAA described the formations as “several sublinear sets of holes in t...
