我关注的是NOAA发现的一个海洋之谜。2022年，一艘NOAA船只在大西洋中大西洋海脊附近探测到一系列奇怪的洞穴，这些洞穴位于约2500米深的海底。这些洞穴直径略大于一厘米，长度几厘米，呈直线排列，看起来非常人工，并非偶然形成。类似的洞穴在2004年也曾被发现。科学家们认为这些洞穴可能与地质活动或某种海洋生物有关。为了查明真相，他们收集了该区域的环境DNA，但结果并未匹配任何已知物种。因此，这些洞穴的成因仍然是一个谜。

Initial theories ranged from tectonic activity to organisms, but collected environmental DNA yielded no matches, leaving the mystery unsolved. The holes were observed in 2004 and again in 2022, adding to the enigma.
  • NOAA ship discovered holes on the Atlantic Ocean floor at 2,500 meters depth
