Mineral Aerosol Input To The Arabian Sea

9311263廷代尔海洋中颗粒的初级生产和垂直通量似乎与不断变化的大气条件有关，就阿拉伯海而言，这些变化的条件包括来自陆地的尘埃通量的变化。作为阿拉伯海过程研究的一部分，这组调查人员将在几次巡航期间测量阿拉伯海上空大气浓度和尘埃通量的变化。在海上时，他们还将估计气溶胶微量金属，特别是铁在海水中的溶解度，并研究对初级生产的影响。通过将这些实地观测与其他调查人员的数据（沉积物陷阱研究和卫星侦察）相结合，调查人员希望将他们的结果外推到更长时间和阿拉伯海地区的区域。

9311263 TINDALE Primary production and the vertical flux of particles in the ocean appear to be linked to changing atmospheric conditions, and in the case of the Arabian Sea these changing conditions include variations in he flux of dust from land. As part of the Arabian Sea Process Study this team of investigators will measure changes in the atmospheric concentrations and flux of dust over the Arabian Sea during several cruises. While at sea they will also estimate the solubility of aerosol trace metals, notably iron, in seawater and study of the effects on primary production. By coupling these field observations with the data of other investigators (sediment trap studies and satellite reconnaissance) the investigators expect to extrapolate their results to longer periods of time and regionally over the Arabian Sea region.
