Collaborative Research: Air/Sea Gas Exchange Studies of Carbon Dioxide, Dimethyl Sulfide, and Acetone by Eddy Correlation

主要研究人员将进行两次研究巡航，在广泛的海洋学条件下使用涡动相关技术测量二氧化碳、二甲基硫化物和丙酮。在赤道太平洋上升流区域的热带巡航将捕捉到世界上大多数海洋特有的中等到低风速条件。太平洋巡航的一个主要目标将是研究气体交换系数随风速的增加。高纬度北大西洋巡航将集中在高生物生产力和高风速地区。在高纬度巡航上，将研究浮游植物大量繁殖对气体交换的影响以及气泡作为气体交换率因素的作用。这些巡航将增加目前海洋直接通量研究的数据库，该数据库非常小，不足以严格描述主要海洋盆地中气体传输系数随风速、海况、生物生产力或季节性变化的变化。本研究更广泛的影响包括来自不同教育水平的学生的参与，从高中实习生到本科生和研究生。未被充分代表的学生将通过外部项目被纳入。还将努力让来自少数民族学区的一名本科生和一名高中教师参加一次研究巡航。

The principal investigators will conduct two research cruises to measure carbon dioxide, dimethyl sulfide, and acetone using the eddy covariance technique over a broad range of oceanographic conditions. A tropical cruise in the equatorial Pacific upwelling region will capture the moderate to low wind speed conditions characteristic of most of the world's oceans. A main goal of the Pacific cruise will be to study the increase of the gas exchange coefficient with wind speed. A high latitude North Atlantic Ocean cruise will focus on areas of high biological productivity and higher wind speeds. On the high latitude cruise the impact of phytoplankton blooms on gas exchange and the role of bubbles as a factor in gas exchange rates will be studied. These cruises will add to the current database of direct flux studies in the oceans, which is extremely small, and insufficient to rigorously characterize the variability in gas transfer coefficients as a function of wind speed, sea state, biological productivity or seasonality in the major ocean basins. The broader impacts of the research include the participation of students from various levels of education from high school interns to undergraduate and graduate students. Underrepresented students will be included through an external program. There will also be an effort made to include an undergraduate student and a high school teacher from a minority school district on a research cruise.
