项目摘要
Proposed studies are designed to address four fundamental questions concerning deep-sea hydrothermal vent and cold-water seep environments: (1) Are biological processes in these environments relatively fast or relatively slow? (2) How do the rates of biological processes vary among a wide variety of geographically-separated hydrothermal systems and, more generally, between deep-sea hydrothermal vent and cold-water seep environments? (3) How do the relatively sedentary organisms encountered at the vents and seeps disperse and subsequently locate and colonize these apparently ephemeral and geographically-separated environments? and (4) What are the time scales associated with vent and seep activity at particular sites throughout the world's oceans? Experiments will be deployed and retrieved (and specimens sampled) using various deep-diving submersibles at six geographically-separated hydrothermal vent areas (Galapagos Rift, 13'N, 21'N, Guaymas Basin, Juan de Fuca Ridge, and Mid-Atlantic Ridge) and one cold-water seep environment (base of the West Florida Escarpment). Detailed comparisons will be made with the experimental results obtained (and specimens at our disposal) from previous hydrothermal vent and cold-water seep expeditions, relying heavily upon mathematical techniques developed during the course of our ongoing NSF-funded studies. Results obtained from the proposed studies should significantly increase our knowledge of both temporal and spatial variability in rates of biological and geological processes within, among, and between deep-sea hydrothermal vent and cold-water seep environments. Finally, the proposed studies involve extensive collaborative efforts with French, Canadian and Mexican scientists which should represent a significant step toward closer integration of the major hydrothermal vent programs presently underway throughout the world's oceans.
拟议的研究旨在解决四个基本问题 深海热液喷口和冷水渗漏问题 环境:(1)生物过程是否在这些环境中 相对快还是相对慢? (2)如何使利率的 生物过程在各种各样的 地理上分离的热液系统, 一般来说,在深海热液喷口和冷水渗漏之间 环境? (3)相对静止的生物是如何 遇到的通风口和渗出分散,随后找到 殖民这些看似短暂的 地理上分离的环境? (4)时间是什么 与特定地点的喷口和渗漏活动有关的规模 遍布全球的海洋 实验将被部署, 使用各种深潜技术回收(和取样)的标本 在六个地理上分散的热液喷口地区的潜水器 (加拉帕戈斯裂谷,北纬13 ',北纬21',瓜伊马斯盆地,胡安·德富卡岭,和 中大西洋海脊)和一个冷水渗漏环境( 西佛罗里达陡崖)。 详细比较将与 获得的实验结果(以及我们所掌握的样品) 从以前的热液喷口和冷水渗漏探险, 在很大程度上依赖于数学技术的发展, 我们正在进行的NSF资助的研究。 所得结果 拟议的研究应该大大增加我们对这两个问题的了解, 生物和生物制品生产率的时间和空间变异性, 深海内部、深海之间和深海之间的地质作用 热液喷口和冷水渗漏环境。 最后 拟议的研究涉及广泛的合作努力, 法国、加拿大和墨西哥的科学家, 朝着更紧密地整合主要热液的重要一步 目前正在世界各地的海洋中进行的喷口计划。
