Modular Autonomous Biosampler(MAB): Multi-platform system for distinct Biological size-class sampling & preservation. Phase II-completion of standalone sampler & AUV adapte

我们在广泛的海洋学平台上收集和保存生物样本的能力存在严重的社区缺陷。pi表明，显然需要的是一个单一的系统，可以很容易地适应多个平台，服务于生物海洋学社区的广泛应用。PIs要求为一项为期3年的开发计划提供资金，以构建和部署两个低成本、高样本容量的模块化自主生物采样设备（mab）。这将包括一个独立的系泊准备单元（额定深度为6000米）和第二个适合直径为20厘米的AUV的单元。该装置将能够同时过滤和保存多种不同的生物大小类别，并将在各种平台模式（AUV， ROV，系泊，观测节点）的任何水生环境中部署。更广泛的影响：鉴于从水样中获取多种尺寸分数的潜力，本文提出的采样器的好处跨越了几个学科。从生物学和地质/生物地球化学的角度来看，这种能力都是有用的。在前一种情况下，浮游动物、浮游植物和浮游细菌群落的研究将以一种相对于传统的、基于船舶的采样应该是高效率和成本效益高的方式进行。在未来，auv对生物特征（如叶绿素斑块、颗粒薄层）的智能跟踪将提高这种高容量采样器的实用性和由这种材料产生的数据。

There is a serious community-wide deficiency in our ability to collect and preserve biological samples across a broad spectrum of oceanographic platforms. The PIs suggest that what is clearly needed is a single system that can be easily adapted to multiple platforms servicing a broad range of applications across the biological oceanographic community. The PIs request funding for a 3-year development program to build and field two low-cost, high-sample capacity modular, autonomous biological sampling devices (MABs). This will include a standalone mooring-ready unit (6000 m depth rating) and a second unit adapted for a 20 cm diameter AUV. The units will be capable of filtering and preserving multiple distinct biological size classes simultaneously, and will be deployable in any aquatic setting from a variety of platform modalities (AUV, ROV, mooring, observatory node).Broader Impacts: The benefits of the sampler proposed herein cut across several disciplines, given the potential for acquiring multiple size fractions from a water sample. This capability will be useful from both a biological and a geological/biogeochemical perspective. In the former case, studies of zooplankton, phytoplankton, and bacterioplankton communities will be accommodated in what should be a highly efficient and cost-effective manner relative to conventional, ship-based sampling. In the future, intelligent tracking of biological features (e.g., chlorophyll patches, particulate thin layers) by AUVs will enhance the utility of such high-capacity samplers and the data generated from this material.
