Invisible Giants: Exploring Phytoplankton Ecology at Oceanic Scales

Session ID#: 258425

Session Description:
Diverse phytoplankton communities span the global ocean pole to pole and play fundamental roles in global carbon cycling, oceanic food webs, and the release of climate relevant compounds to the atmosphere. The composition and productivity of phytoplankton communities are often linked to nutrient and micronutrient distributions driven by abiotic and biotic processes. This session focuses on phytoplankton ecology at the community and ecosystem levels of organization and over large spatial scales from coastal seas, ocean basins, and the global ocean. Topics can include biogeography, climate-induced range shifts, community composition and structure (e.g., species, functional groups, or size structure), large scale productivity, and interactions with biogeochemical cycling. Submissions that include imaging technologies, ‘omics, eDNA, and modeling – including machine learning – are all welcome, as well as those linking these approaches to the new era of hyperspectral satellite ocean color measurements.
