SGER: Surface Ocean CO2: Relationships with Satellite- based Measurements of Ocean Color, Sea Surface Temperature, and Continental Dust at Ocean Station P

在这个项目中，首席研究员将利用一次海洋学巡航的机会，研究东北太平洋表层海水中二氧化碳的原位分压与美国宇航局SeaWiFS卫星的海洋颜色卫星数据之间的关系。这个被称为“帕帕海洋站”的地点在过去的二十年里得到了很好的研究，因此有一个关于二氧化碳、叶绿素- a和其他与海洋碳循环有关的变量的极好的历史数据库。众所周知，该地点在海面温度和初级生产方面存在季节性变化，这两者都可以通过卫星颜色传感器观察到。首席研究员将探索二氧化碳分压与这两个变量之间的关系，以及与大气尘埃的偶发输入之间的关系，这可以通过卫星气溶胶图像观察到。如果成功，该项目最终可以扩展到监测和绘制全球海洋表面二氧化碳物理化学状态的变化

9814388 DeGrandpre In this project, the principal investigator will take advantage of an oceanographic cruise of opportunity to study the relationship between the in-situ partial pressure of carbon dioxide in surface seawater of the northeast Pacific Ocean and ocean color satellite data from the NASA SeaWiFS satellite. The site, called Ocean Station Papa, has been well studied over the past two decades, so there is an excellent historical database of carbon dioxide, chlorophyll- a, and other variables related to the oceanic carbon cycle. The site is known to undergo seasonal variations in sea surface temperature and primary production, both of which are observable by satellite color sensors. The principle investigator will explore relationships between the partial pressure of carbon dioxide and these two variables and also with episodic inputs of atmospheric dust, which is observable with satellite aerosol images. If successful, the project could be extended eventually to monitor and map variations in the CO2 physicochemical state of the surface ocean worldwide
