几年前在靠近加拿大西海岸的大西洋底发现了深5～10米、直径15～45米的小型“环形山”群。不久前在北海、奥克尼群岛和设得兰群岛以东又发现海底广泛布有类似于月球上的“环形山”。由于这个地区距英国大型海上油田——福蒂斯油田只有20海里,所以爱丁堡(苏格兰)地质科学研究院对它进行了调查研究。科学家们认为,现在发现的“环形山”很可能不是 A few years ago, a small “craters” of 5 to 10 meters deep and 15 to 45 meters in diameter were found on the Atlantic Ocean near the west coast of Canada. Not long ago, in the North Sea, the Orkney Islands and the east of the Shetland Islands, it was discovered that the crater resembled the “crater” on the moon. As the area is only 20 nautical miles from the large offshore oilfield in the United Kingdom, the Fortis Oilfield, the Institute of Geological Sciences of Edinburgh (Scotland) conducted a survey. Scientists believe the Craters now discovered are probably not
