Marine phytoplankton are key players in the global carbon cycle as they are responsible for half of the primary production (conversion of carbon dioxide and water into oxygen and organic carbon via photosynthesis) on Earth. 控制浮游植物生长的主要因素是光照和养分的有效性.
Both observations and models have suggested that upper ocean mesoscale (eddies) and submesoscale processes (fronts) play an important role along with atmospheric forcing in regulating the availability of these resources and therefore phytoplankton community growth. 这些过程, 影响水层之间的垂直交换, regulating the light field and nutrient availability for the phytoplankton community at small spatial (metres to kms) and short temporal scales (daily to sub-daily), 哪些与浮游植物的适应和驯化有关.
Models with sufficient resolution to evaluate these processes are computationally expensive and most observation platforms (e.g. Argo浮动)不采样和解决每日到次每日的变化.
在这个项目中, you will use high-resolution gliders to (1) understand and quantify the effect of small-scale and episodic physical processes on the phytoplankton community growth; (2) evaluate the importance of including small-scale processes in oceanic carbon uptake. Filling this knowledge gap using these high-resolution data will improve predictions of how the carbon uptake by phytoplankton is affected by both natural variability and changes in physical forcing driven by climate change.
