Archiving the Karen Von Damm Legacy Hydrothermal Fluid Collection

在世界大洋中脊循环的热液流体为地幔和地壳中海水与洋壳之间发生的一级化学交换过程提供了基本线索。 这些流体为热液生态系统提供了必要的营养物质，是许多海洋元素收支的重要组成部分。 该项目将卡伦·冯·达姆博士在因癌症过早去世之前从9个不同的中洋脊喷口系统收集的32次以上的航行中收集的热液喷口流体样本存档。样本包括时间序列流体访问东太平洋隆起（EPR）9-10 N喷口，在两个火山喷发周期的时间间隔。 高质量的数据集，相关的分析建模和许多热液系统的解释，特别是那些沿着EPR由冯达姆博士产生的也将被存档在NSF资助的数据库。 这项工作还包括将2004年以前收集的现有液体样本妥善存档，并建立一个处理和分发样本请求的机制。 这项工作的更广泛的影响包括支持两名早期职业教师，他们的性别在科学领域代表性不足。

Hydrothermal fluids circulating at the world's mid-ocean ridges provide fundamental clues to first-order chemical exchange processes occurring in the mantle and crust between seawater and the ocean crust. These fluids provide essential nutrients to hydrothermally based ecosystems and constitute a crucial component of many oceanic elemental budgets. This project archives hydrothermal vent fluid samples from over 32 cruises from nine different mid ocean ridge vent systems collected by Dr. Karen Von Damm prior to her untimely demise from cancer. Samples include time series fluids from visits to the East Pacific Rise (EPR) 9-10 N vents, over a time interval of two volcanic eruption cycles. High quality datasets, associated analytical modeling and interpretations for many hydrothermal systems, especially those along the EPR that were generated by Dr. von Damm will also be archived in NSF-funded databases. The work also involves properly archiving existing fluid samples collected prior to 2004 and establishing a mechanism for handling and distributing requests for samples. Broader impacts of the work include support of two early career faculty whose gender is under-represented in the sciences.
