9633353海水通过海洋地壳的环流对海洋的化学成分有重大影响。这一点在大洋中脊上已经得到了很好的理解，因为流出流体的成分是已知的。然而，离轴排气对海洋化学的影响更大，但这种排气很普遍，尚未进行采样。我们对离轴循环对海水影响的唯一了解来自于钻井开采的岩石。pi将测量钻孔中矿物的组成，并确定它们的丰度，以估计有多少水在地壳中循环，以及它如何改变地壳。
英文摘要
9633353 Alt Circulation of sea water through the ocean crust has a major effect on the chemistry of the oceans. This is fairly well understood at mid-ocean ridges because the composition of the exiting fluids is known. However, off-axis venting has a larger effect on ocean chemistry but the venting is widespread and has not yet been sampled. Our only knowledge of the effect of off-axis circulation on seawater is from rocks that have been recovered by drilling. The PIs will measure the composition of minerals from drill hole and determine their abundance to estimate how much water has circulated through the crust and how it changed the crust.
