Trace Element Geochemistry of the Eastern Mediterranean and the Black Sea

该奖项支持约翰·埃德蒙兹博士参加1988年R.V. KNORR号前往地中海和黑海的计划探险的其中一站。将对温度、盐度、营养物质、氧气、氟利昂和几种微量元素进行测量，并收集水样进行进一步的实验室分析。东地中海和黑海是海洋地球化学中最不为人所知的地区之一，该计划旨在确定黑海深水的组成，垂直混合的速度，以及黑海发生的过程产生的垂直梯度。获得的信息可用于解决氧化还原过程在缺氧/缺氧过渡区的时间限制，沉淀反应和/或铝硅酸盐成岩作用的证据。此外，这项工作可能有助于解决诸如Al和Be在地中海和太平洋的清除与定居等问题。

This award supports Dr. John Edmonds' participation on one leg of the scheduled expedition of the R.V. KNORR to the Mediterranean and Black Sea in 1988. Measurements of temperature, salinity, nutrients, oxygen, freons and several trace elements will be carried out and water samples collected for futher laboratory analysis. The Eastern Mediterranean and Black Sea are among the least known areas of the ocean geochemically, and this program is aimed at determining the composition of deep waters in the Black Sea, the rate of vertical mixing, and the vertical gradients produced by processes occurring in the Black Sea. Information gained can be used to address time constraints on redox processes at the oxic/anoxic transition zone, evidence of precipitation reactions and/or aluminosilicate diagenesis. In addition, this work may help resolve such problems as scavenging versus settling of Al and Be in the Mediterranean and the Pacific.
