A New Instrument: Buoy Aerosol Sampling System

小行星9423212 伍兹霍尔海洋学研究所将开展一个海洋科学仪器开发项目，设计、建造和测试一个可安装在浮标上的气溶胶收集器。 这一新工具的目的是帮助更好地了解大气微粒沉积与上层海洋化学和生物之间的时间和质量耦合。 该采样器将配备电池驱动的气泵、监测过滤速率的质量流量计、测序样品收集器以及与IMET（改进的气象海洋测量）系统的接口。 气溶胶收集器将设计用于离散时间序列和时间积分样本。 这将对时间序列取样进行质量平衡检查。 此外，将对不同类型的过滤器进行测试，以收集不同化学类型的样本。 该系统将与百慕大AEROCE塔上的常规气溶胶采样系统进行校准。 这将允许与AEROCE大容量采样器收集的气溶胶进行直接比较。

9423212 Sholkovitz The Woods Hole Oceanographic Institution will undertake an ocean sciences instrumentation development project to design, build and test an aerosol collector that would be deployable on buoys. The purpose of this new instrument is to help derive a better understanding of the temporal and qualitative coupling between atmospheric deposition of particulates and upper ocean chemistry and biology. The sampler will feature battery driven air pumps, mass flow meters to monitor filter rate, sequencing sample collectors, and an interface with IMET (Improved Meteorological Marine Measurements) systems. The aerosol collector will be designed for both discreet time-series and time-integrated samples. This will provide a mass balance check on time series sampling. Additionally, filters of varying types will be tested for collecting samples of different chemical types. The system will calibrated with conventional aerosol sampling systems on the AEROCE tower on Bermuda. This will allow direct comparison with the aerosols collected by the AEROCE high-volume sampler.
