Modular Autonomous Biosampler (MAB): A Multi-platform System for Distinct Biological Size-class Sampling and Preservation

在过去的10-15年里，新型传感器平台的开发和应用取得了巨大的增长，特别是自主和拉格朗日平台，如自主水下航行器、漂流器和海洋滑翔机，以及综合海洋观测系统（OOSs）领域。生物传感器领域的平行增长仍然远远落后于地球物理采样，而生物采样在全球OOS系统的实施中是一个代表性不足的部门。然而，利用生物和化学传感器进行发现和环境健康评估的潜力非常大。PI的建议是设计和集成当前现成的技术到一个新的配置中，这是以前没有完成的。虽然像Hardy连续浮游生物采样器（1930）这样的系统确实对这个项目有一定的历史影响，并且肯定地指出了对我们所提议的系统的长期需求，但开发一种新型的模块化、独立的、可编程的泵滤系统是一项明显不同的任务。鉴于社区迫切需要与现有和计划中的海洋观测站和系泊网络相联系的生物采样，开发这种装置尤为紧迫。更广泛的影响开发一种低成本的高容量智能生物采样器，能够长时间存储样本以供以后分析，这将满足进入这些海洋中大量研究不足区域的关键需求。提出的模块化自主生物采样器有可能大大提高我们的远程长期生物监测能力。生物和化学传感器在发现和环境健康评估方面的潜力非常大。

The last 10-15 years has seen a tremendous growth in the development and application of new sensor platforms, specifically autonomous and Lagrangian platforms such as Autonomous Underwater Vehicles, drifters, and ocean glider and in the realm of integrated Ocean Observing Systems (OOSs). A parallel growth in the realm of biosensors remains significantly behind that of the geophysical sampling and biosampling is an under-represented sector in the implementation of OOS systems worldwide. Nevertheless, the potential for discovery and environmental health assessment from biological and chemical sensors is extremely high. The PI's propose to design and integrate current-off-the-shelf technology into a novel configuration that has not been accomplished before. While it is true that systems like the Hardy Continuous Plankton Sampler (1930) have some historical bearing on this project, and certainly point to the long standing need for a system such as we are proposing, the development of a new class of modular self-contained, programmable pump-filter systems is a significantly distinct undertaking. The development of this device is particularly urgent given the critical need in the community for biological sampling in connection with existing and planned ocean observatory and mooring networks. Broader ImpactsThe development of a low-cost high capacity smart biosampler that has the ability to store samples for extended periods of time for later analysis will satisfy the critical need to access these vastly understudied areas of our oceans. The proposed modular autonomous biosampler has the potential to dramatically increase our remote long-term biological surveillance capabilities. The potential for discovery and environmental health assessment from biological and chemical sensors is extremely high.
