小行星9617721 近年来，化学和生物海洋学家逐渐认识到，远离陆地的广大海洋区域的初级生产力，曾经被认为是受 进入地表沃茨的无机氮的有效性实际上受到铁的限制。 现在，对这一令人兴奋的发现的进一步详细研究正在进行中，需要深入了解海水中溶解铁的分子水平行为。 本提案旨在满足这一需求。 首席研究员是海水物理化学方面的世界权威，他将进行一系列实验室研究，以确定海水中铁的基本化学性质。 这些研究将包括铁溶解度的研究， 各种条件和铁的络合行为-即，海水中无机和有机物质结合铁从而影响 其溶解度和生物利用度。 动力学和热力学 铁的（平衡）方面 溶液 和络合作用将在海水化学的更一般的理论模型的背景下进行研究。 ***

9617721 Millero In recent years, chemical and biological oceanographers have come to realize that primary production in vast areas of the ocean far from land, once thought to be limited by the availability of inorganic nitrogen coming into surface waters, is in fact limited by iron. Now that further , more detailed studies of this exciting discovery are underway, there is a need for in-depth understanding of the molecular-level behavior of dissolved iron in seawater. This proposal is directed toward meeting this need. The principal investigator, a leading world authority on the physical chemistry of seawater, will carry out a series of laboratory studies to determine the fundamental chemical properties of iron in seawater. These investigations will include studies of iron solubility under various conditions and of the complexation behavior of iron - i.e., the ability of inorganic and organic substances in seawater to bind iron and thus affect its solubility and biological availability. Both the kinetic and thermodynamic (equilibrium) aspects of iron solution and complexation will be studied in the context of more general theoretical models of seawater chemistry. ***
