自从在太平洋深水中发现过量3 He 1以来，一直认为这种异常的来源是来自海底扩张中心的原始氦的中深度注入1，2。这一假设与过量3 He在深水中的空间分布3 -5、其存在于挤压海洋玄武岩的玻璃状（快速淬火）边缘6、7以及在加拉帕戈斯扩张中心上方的“热羽流”（热异常> 0.1 °C，使用深拖雪橇采样）中检测到大量过量3 He 8 -10是一致的。在这份报告中，我们总结了37个测量过量的氦在热液沃茨采样使用阿尔文深潜器在加拉帕戈斯蔓延中心在1977年2月和3月。
SINCE the discovery of excess3He in Pacific deep waters1, it has been argued that the source of this anomaly is the mid-depth injection of primordial helium from seafloor spreading centres1,2. This hypothesis is consistent with the spatial distribution of excess3He in the deep waters3–5, its presence in the glassy (rapidly quenched) margins of extruded ocean basalts6,7, and the detection of a large3He excess in a ‘thermal plume’ (thermal anomaly ∼0.1 °C, sampled using a deep-tow sled) over the Galapagos Spreading Centre8–10. In this report, we summarise 37 measurements of excess helium in hydrothermal waters sampled using the Alvin deep submersible at the Galapagos Spreading Centre during February and March of 1977.
