Archiving the Karen Von Damm Legacy Hydrothermal Fluid Collection

在世界大洋中脊循环的热液流体为海水和海洋地壳之间发生在地幔和地壳中的一级化学交换过程提供了基本线索。这些流体为基于热液的生态系统提供了必需的营养物质，并构成了许多海洋元素收支的重要组成部分。该项目记录了凯伦·冯·达姆博士在因癌症过早去世之前，从9个不同的洋中脊喷口系统收集的超过32次巡航的热液喷口液体样本。样品包括在两个火山喷发周期的时间间隔内访问东太平洋隆起（EPR） 9-10 N喷口的时间序列流体。高质量的数据集，对许多热液系统的相关分析建模和解释，特别是由冯·达姆博士产生的沿着EPR的热液系统，也将存档在nsf资助的数据库中。这项工作还涉及妥善归档2004年以前收集的现有流体样品，并建立处理和分发样品请求的机制。这项工作的更广泛影响包括支持两名在科学领域性别代表性不足的早期职业教师。

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.
