The PI requests MRI funding to develop and evaluate the performance of a novel profiling buoy system for the calibration of satellite ocean color observations and the validation of their data products. This measurement capability is essential for creating long-term satellite climate data records of the ocean biosphere The Near Surface Profiling Buoy (NSPB), will autonomously collect 100's of high-quality, near-surface irradiance / radiance profiles during each multi-day deployment as part of a standard oceanographic research cruise. The NSPB is built upon recent advances in optical profiling instrumentation designed for turbid water environments that is adapted to the calibration and validation of ocean color satellite data. The NSPB system is aimed at making day-long to week-long deployments improving the likelihood of high quality match-ups with satellite data than is possible with conventional profiling techniques.Broader ImpactsIncreased provision of sea-truth radiometry for vicarious calibration of ocean colour sensors, particularly in geographical regions not covered by existing installations, is urgently required by the remote sensing community. In principle, the buoy-plus-profiler device offers a novel and exciting technique for satisfying this need. The improved satellite validation and calibration made possible by the proposed instrumentation will likely benefit a wide group of scientists and other users. The proposed solution combines the benefits of a moored system with a boat based deployment. The buoy will be left so that it can collect large amounts of data, but not so long that bio-fouling starts to become a significant issue. In addition, the smaller overall size will reduce the infrastructure required for deployment. The proposal highlights the positive impact this development will have on a commercial company (Biospherical Instruments, Inc.).

PI要求MRI资助开发和评估一种新型剖面浮标系统的性能，用于校准卫星海洋颜色观测及其数据产品的验证。这种测量能力对于创建海洋生物圈的长期卫星气候数据记录至关重要近地表剖面浮标（NSPB）将在每次多日部署期间自动收集100个高质量的近地表辐照度/辐射率剖面，作为标准海洋学研究巡航的一部分。NSPB是建立在光学剖面测量仪器的最新进展之上的，该仪器专为浑浊的水环境设计，适用于海洋颜色卫星数据的校准和验证。NSPB系统的目的是使为期一天至一周的部署，提高高质量的匹配的可能性，与卫星数据比可能与传统的profiling techniques.Broader impactsIncreased提供海洋真理辐射测量替代校准的海洋颜色传感器，特别是在地理区域不包括现有的安装，是迫切需要的遥感界。原则上，微处理器加轮廓仪设备提供了一种新颖而令人兴奋的技术来满足这一需求。拟议的仪器使改进卫星验证和校准成为可能，这可能使广大科学家和其他用户受益。所提出的解决方案结合了系泊系统与基于船的部署的优点。浮标将被留下，以便它可以收集大量的数据，但不会太长，生物污垢开始成为一个重要的问题。此外，较小的总体规模将减少部署所需的基础设施。该提案强调了这一发展将对商业公司（Biospherical Instruments，Inc.）产生的积极影响。
