二战期间,德国纳粹潜艇U864号满载飞机零件和水银罐由德国基尔港出发,准备前往日本,在驶抵挪威附近海域时被英国潜艇“冒险”号击沉,从此长眠海底60余年。长期海水侵蚀,水银不断泄漏,对海洋环境构成严重威胁。为此,挪威政府不惜动用10万立方沙土、耗费800万英镑巨资,准备为U864残骸打造一个海底“石棺”。 During World War II, Germany’s Nazi submarine U864, loaded with aircraft parts and mercury cans, departed from Kiel, Germany, ready to go to Japan and was submerged for more than 60 years by the British submarine “Adventure” while sailing to the sea near Norway. Long-term seawater erosion, mercury continued to leak, pose a serious threat to the marine environment. To this end, the Norwegian government has resorted to 100,000 cubic meters of sand and soil, spent 8 million pounds heavily in preparation for the U864 wreckage to create a seabed “sarcophagus.”
