A New Instrument: Buoy Aerosol Sampling System

点击翻译按钮获取中文摘要

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.
