New, comprehensive collections of marine macrofauna will be made at hydrothermal vents on Gorda Ridge, a geographically isolated Northeast Pacific ridge that has been subject to local extinctions, and at deep cold seeps on the Monterey Fan Valley system. Collections of invertebrates from the Gorda Ridge vents and from cold seeps, chemically similar areas where taxa depend on reduced fluids released independent of hydrothermal vents to sustain chemosynthesis, will document the species present, their level of habitat restriction and assess how physical differences among these habitats affect species diversity. The isolation of Gorda Ridge vents from other North Pacific vents by a 350 km offset suggests that their fauna may be distinct; the contrast between the sedimented southern and the rocky northern vents on this ridge heightens the scientific benefit to be derived from these collections. A guide to the identification of North Pacific vent and seep taxa will be made available on the web and on a CD-ROM.

新的、全面的海洋大型动物群的收集将在戈尔达山脊的热液喷口进行，戈尔达山脊是一个地理上孤立的东北太平洋山脊，已经受到局部灭绝的影响，以及在蒙特利扇谷系统的深冷泄漏处。从Gorda Ridge喷口和冷渗漏中收集无脊椎动物，化学性质相似，类群依赖于独立于热液喷口释放的减少液体来维持化学合成，将记录现有的物种，它们的栖息地限制水平，并评估这些栖息地之间的物理差异如何影响物种多样性。戈尔达岭火山口与其他北太平洋火山口相隔350公里，这表明它们的动物群可能是不同的；在这个山脊上沉积的南部和岩石的北部喷口之间的对比，提高了从这些收集中获得的科学效益。将在网上和光盘上提供北太平洋喷口和渗漏分类群的鉴定指南。
