最近，我们在爱尔兰西南部的豪猪盆地（Porcupine Basin）巡航时，发现了两个迄今为止几乎没有人想到的广阔的深水暗礁区，包括一个由数百个掩埋的土丘组成的巨大集群。许多珊瑚礁的环状形状表明，它们是由海底轴向流体排出造成的，这是一种在空间和时间上受到良好限制的短暂流动。我们正在探索各种各样的假设，但一个令人兴奋的研究途径是由冰川控制的生长脉冲和随后的天然气水合物浅层的衰减，作为甲烷缓冲层，可能间接作为上覆生物群落的地面。
During a recent cruise in the Porcupine Basin, off southwest Ireland, we discovered two extensive and hitherto largely unsuspected deep-water reef provinces, including a giant cluster of hundreds of buried mounds. The ring shapes of many reefs suggest that they are caused by an axial fluid expulsion at the sea bed, a transient flow well confined in space and time. We are exploring various hypotheses, but a stimulating avenue for research is opened by a glacially controlled growth pulse and subsequent decay of a shallow layer of gas hydrates as a methane buffer and probably indirectly as a ground for overlying biological communities.
