Examinations of phytoplankton physiology in the face of changing pH are becoming more important as anthropogenically-driven pH decreases in the surface ocean progress (termed ocean acidification). Previous research has shown that phytoplankton response to acidification are highly variable, with some taxa showing improvement and some showing marked deterioration. This dissertation examines the effect of steady state and changing pH environments on the internal pH, esterase activity, and photosynthetic efficiency (the latter two parameters are involved with energy production or utilization) of the marine phytoplankton species, Isochrysis galbana. 000007610 542__ $$fIn copyright - single owner 000007610 650__ $$aEngineering$$018450 000007610 650__ $$aNatural Resources$$011204 000007610 650__ $$aHaptophyta$$039086 000007610 650__ $$aEcology$$018187 000007610 650__ $$aOceanography$$023143 000007610 691__ $$aSchool of Medicine$$041369 000007610 692__ $$aDepartment of Environmental Science and Engineering$$041415 000007610 7001_ $$aGolda, Rachel L. 000007610 8564_ $$941b19c25-821b-4e11-b0ab-cbf7137c5d13$$s4324259$$uhttps://digitalcollections.ohsu.edu/record/7610/files/Golda.Rachel.2017.pdf 000007610 905__ $$a/rest/prod/3j/33/32/80/3j333280s 000007610 909CO $$ooai:digitalcollections.ohsu.edu:7610$$pstudent-work 000007610 980__ $$aTheses and Dissertations
