The PIs request funding to design, develop, test, and deploy a sampler capable of recovering microbial mat samples from a variety of deep-sea ocean ecosystems with a spatial sampling resolution on the order of a centimeter or less. Compared to current deep-sea benthic sampling tools, this instrument has the potential to collect better samples, and, more significantly, expand the questions asked by researchers investigating microbial ecosystems. Microbial mat ecosystems are critically important for a wide variety of biogeochemical transformations in an even wider variety of habitats. These productive microbial communities are highly structured into layers of activity that respond to the particular geochemical gradients that are supplying them. In the deep ocean, microbial mats abound around hydrothermal systems, as well as other sites such as cold methane seeps or organic-rich environments. Broader Impacts:The microbial mat sampler is a tool that is greatly needed and will have a positive impact on every researcher studying microbial mats in the deep-sea. The collaboration with the Picker Engineering Program at Smith College is innovative and seems like an excellent way of inspiring young women in the sciences. What a fantastic idea: to get young college students directly involved in the real world application/design of scientific equipment. One of the PIs is an early-career scientist with substantial expertise in the design of deep-sea samplers.

PIS请求资金来设计，开发，测试和部署能够从各种以厘米或更少的空间采样分辨率的深海海洋生态系统中恢复微生物垫样品的采样器。与当前的深海底栖采样工具相比，该仪器有可能收集更好的样品，并且更重要的是扩大了调查微生物生态系统的研究人员所要求的问题。微生物垫生态系统对于更广泛的栖息地中的各种生物地球化学转化至关重要。这些生产性微生物群落高度结构化为活动层，这些活动对提供它们的特定地球化学梯度做出反应。在深海中，微生物垫子周围充满了水热系统，以及其他地点，例如冷甲烷渗漏或有机富裕的环境。更广泛的影响：微生物MAT采样器是一种非常需要的工具，将对每个研究深海中微生物垫的研究人员产生积极影响。与史密斯学院（Smith College）的Picker工程计划的合作是创新的，似乎是激发科学中年轻女性的绝佳方式。一个很棒的主意：让年轻的大学生直接参与科学设备的现实世界应用/设计。其中一个PI是一位早期职业科学家，在设计深海采样器的设计方面具有丰富的专业知识。
