Archiving the Karen Von Damm Legacy Hydrothermal Fluid Collection

在世界大洋中脊上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。这些流体为以水热为基础的生态系统提供必要的营养物质，并构成许多海洋要素预算的重要组成部分。该项目存档了Karen Von Damm博士在她因癌症过早去世之前收集的来自九个不同大洋中脊喷口系统的32多个邮轮的热液喷口流体样本。样本包括访问东太平洋隆起(EPR)9-10 N喷口的时间序列流体，时间间隔为两个火山喷发周期。冯·达姆博士为许多热液系统，特别是EPR沿线的热液系统生成的高质量数据集、相关的分析模型和解释也将保存在国家科学基金会资助的数据库中。这项工作还涉及对2004年前收集的现有流体样本进行适当存档，并建立处理和分发样本请求的机制。这项工作的更广泛影响包括支持两名早期职业教师，他们的性别在科学界的代表性不足。

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.
