The funding provided here will be used to support participation in a scientific workshop on the topic of what happens to iron deposited from the atmosphere to the surface of the ocean. Iron is required for the growth of phytoplankton. The availability of iron can limit the growth of phytoplankton and thus the overall productivity of the marine ecosystem. Workshop participants with expertise in atmospheric chemistry, organic geochemistry, photochemistry, chemical oceanography, dust/aerosol geochemistry, and various aspects of atmospheric, ocean, and Earth system modeling will be brought together to discuss the complicated problem of iron chemistry at the atmosphere-ocean interface, and its effects. At least one-third of workshop invitees will be early-career scientists. The primary product of the workshop will be a white paper outlining the state of knowledge and prioritizing future research directions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这里提供的资金将用于支持参加一个科学研讨会，该研讨会的主题是铁从大气沉积到海洋表面的过程。铁是浮游植物生长所必需的。铁的可用性可以限制浮游植物的生长，从而限制海洋生态系统的整体生产力。来自大气化学、有机地球化学、光化学、化学海洋学、粉尘/气溶胶地球化学以及大气、海洋和地球系统模拟等各个方面的专家将齐聚一堂，讨论大气-海洋界面铁化学的复杂问题及其影响。至少三分之一的研讨会受邀者将是职业生涯初期的科学家。研讨会的主要成果将是一份概述知识状况和未来研究方向的白皮书。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
