1. Marine Biogeochemistry & Phytoplankton Biogeography Kate Mackey Claire Booth Luce Associate Professor, Earth System Science, UCI Academic Background • Postdoctoral Fellow, WHOI & MBL • PhD Stanford, Civil & Environmental Engineering • BS U Maryland, Plant Biology • BS U Maryland, Biological Engineering • Human influence on marine phytoplankton communities and biogeochemical consequences using multi-stressor approaches; trace metal biogeochemistry, climate change, atmospheric pollution from various sources (shipping & industry emissions) • The role of photosynthetic adaptation traits and regulation of acclimation processes in marine phytoplankton competition and biogeography • Competitive and beneficial interactions in phytoplankton communities; how interactions limit and sustain diversity, particularly among closely related species and strains with overlapping niches; Synechococcus specialization • Field and laboratory methods; specialty in field manipulation experiments, including incubation studies to understand how phytoplankton respond to changing environmental variables over time; flow cytometry and light microscopy
2. Ecosystem shifts and climate change How will viral activity change in a warmer ocean? Will sea ice loss lead to changing food web structure? Impact of sea ice loss on under-ice blooms How do under-ice blooms contribute to total productivity? How does sea ice reduction affect the timing of blooms? How will changes in stratification and light interact? Role of iron and micronutrients How will changing iron supplies alter phytoplankton species? What are the impacts of trace metal co-limitation? How is carbon dioxide removal potential affected? Biological pump and carbon sequestration Are phytoplankton sequestering or recycling more carbon? How do species shifts affect carbon export?
