Active Hydrothermal Vents on the Mid-Atlantic Ridge

这项研究是最近两项研究的延续。 在大西洋中脊发现了活跃的热液区 主要焦点是北纬26度的TAG丘。 这是 在海底观测到的最大活跃磁场， 主要矿石存款的规模和品位。 此字段将 彻底采样，以表征各种水 类型，并评估其在形成，生长和 存款演化 南部领域，“蛇坑”在MARK地区23 N将 来研究它的时间演变。 将尝试 以确定ODP漏洞的位置，以确定它们是否对 关于热液循环

This research is a continuation of a study of two recently discovered active hydrothermal fields on the mid-Atlantic ridge. The principal focus is the TAG mound at 26 N. This is the largest active field observed on the seafloor and has the dimensions and grade of a major ore deposit. This field will be sampled thoroughly in order to characterize the various water types and to evaluate their role in the formation, growth, and evolution of the ore deposit. The southern field, "Snake Pit" in the MARK area 23 N will be sampled to study its temporal evolution. An attempt will be made to locate the ODP holes to find out if they had any effect on the hydrothermal circulation.
