Impact of Convective Processes and Sea Ice Formation on the Distribution of Iron in the Ross Sea: Closing the Seasonal Cycle

罗斯海大陆架的沃茨是南大洋中生产力最高的水域之一，可能是大气二氧化碳的重要海洋汇。在这一地区，初级生产力可能会受到生长季节表层沃茨溶解铁供应的限制。为了更好地了解浮游植物动态，沿着碳输出，将在夏末-秋季-初冬时间框架内在罗斯海进行一系列地球化学测量和活动。 这些地球化学参数包括铁、碳和硫等元素，据信这些元素对南极生态系统很重要。 除了对罗斯海生态系统的功能感兴趣，导致即将到来的极夜，还有不确定性，是什么驱动了微量营养素Fe物种在一年中的这个时候广泛的海冰形成过程中经历的地球化学再分配。现场设置和远程条件，伴随着拟议的研究提出了几种可能性，在K-12的STEM教育和培训，本科生和研究生水平，以及公共宣传。在K-12一级，该项目寻求支持针对中小学生、职前科学教师和在职科学教师的教育宣传材料的开发。

The waters of the Ross Sea continental shelf are among the most productive in the Southern Ocean, and likely comprise a significant oceanic sink for atmospheric carbon dioxide. In this region, primary production can be limited by the supply of dissolved iron to surface waters during the growing season.A range of biogeochemical measurements and activities are to be carried out in the late summer-autumnal- early winter time frame in the Ross Sea in order to better understand phytoplankton dynamics, along with carbon export. These biogeochemical parameters include elements such as Fe, C and S believed to be important to Antarctic ecosystems. As well as there being interest in the functioning of the Ross Sea ecosystem leading up to the impending polar night, there is also uncertainty as to what drives the biogeochemical redistribution undergone by micronutrient Fe species during the extensive sea-ice formation at this time of year.The field setting and remote conditions that accompany the proposed study present several possibilities for STEM education and training at the K-12, undergraduate and graduate levels, as well as for public outreach. At the K-12 level, the project seeks to support the development of educational outreach materials targeting elementary and middle school students,pre-service science teachers, and in-service science teachers.
