The PIs request funding to develop a rapid vertical profiling autonomous underwater vehicle with biogeochemical sampling capabilities. This system will add a new, and much needed, biological dimension to the GEOTRACES program, and would most likely become the central instrument for a GENOTRACES microbial and enzymes research initiative - ultimately enabling the global marine mapping of microbial DNA, RNA and proteins, including key biogeochemical enzymes. The PIs will develop a wireless water-column sampling technology: a 6000m rated autonomous vertical sampling vehicle with a high throughput sampling and sensing payload. The combinationof rapid vertical transport, the 6000 m depth range, and the need to stop at numerous target depths represents a novel and significant engineering challenge and developing a vehicle capable of this task with the sampling capacity needed for GENOTRACES "-omic" sampling is the objective of this proposal.Broader Impacts: This project leads oceanic sample collection into the future where they will need to be collected from a variety of autonomous platforms. This is of great societal importance because understanding the ocean, its sheer magnitude, and its role in global processes will require more than ships and moorings, it will take samples from many parts of the ocean and their analysis by many techniques for many different analytes. This project will also sponsor two consecutive teams of undergraduate female engineering students from Smith College's Picker Engineering Program during their senior engineering design course. This is seen as a real plus and an innovative outreach effort. The PI has very successfully done this in the past.

PIs申请资金用于开发具有生物地球化学采样能力的快速垂直剖面自主水下航行器。该系统将为GEOTRACES项目增加一个新的、急需的生物维度，并极有可能成为GENOTRACES微生物和酶研究计划的核心工具——最终实现微生物DNA、RNA和蛋白质的全球海洋测绘，包括关键的生物地球化学酶。pi将开发一种无线水柱采样技术：一种具有高通量采样和传感有效载荷的6000米额定自动垂直采样车辆。快速垂直运输，6000米深度范围，以及需要在多个目标深度停止的组合代表了一个新的和重大的工程挑战，开发一种能够完成这项任务的车辆，并具有GENOTRACES“- omics”采样所需的采样能力，这是本提案的目标。更广泛的影响：该项目将海洋样本收集带入未来，届时它们将需要从各种自主平台收集。这具有重大的社会意义，因为了解海洋，它的巨大规模，以及它在全球进程中的作用，将需要的不仅仅是船只和系泊，它将从海洋的许多部分采集样本，并通过许多技术对许多不同的分析物进行分析。该项目还将资助史密斯学院Picker工程项目的两个连续的本科女工程学生团队，在他们的高级工程设计课程中学习。这被视为一个真正的优势和创新的推广工作。PI过去在这方面做得非常成功。
