This instrumentation development award provides funds to develop a buoy-mounted instrument that is capable of measuring the rain water concentrations of dissolved Fe(II) and Fe(III) in an autonomous and real-time manner. This data will allow scientists to quantify the wet deposition of iron in the oceans. The proposed research is joint Dr. Robert Byrne at the University of South Florida, and involves coupling a long pathlength Liquid Core Waveguide absorbance spectrometer developed at USF to the buoy-mounted rainwater collector, aerosol sampler and meteorological sensors developed at WHOI. The system will be tested on shore and then on a buoy moored off Woods Hole, MA in the summer of 2000.

该仪器发展奖提供资金，以开发一种浮标安装的仪器，能够以自主和实时的方式测量雨水中溶解的Fe(II)和Fe(III)的浓度。这些数据将使科学家能够量化海洋中铁的湿沉积。这项拟议的研究是与南佛罗里达大学的Robert Byrne博士联合进行的，涉及将USF开发的长距离液芯波导吸收光谱仪与WHOI开发的浮标安装的雨水收集器、气溶胶采样器和气象传感器进行耦合。该系统将在岸上进行测试，然后于2000年夏天在马萨诸塞州伍兹霍尔附近的一个浮标上进行测试。
