Limiting Nutrient Concentrations and Nutrient Assimilation and Storage Gene Expression across the Transition Zone Chlorophyll Front in the North Pacific Ocean

This study investigates limiting nutrient-relevant cyanobacterial gene expression across the Transition Zone Chlorophyll Front (TZCF) in the north Pacific Ocean. An increase in available nutrients due to upwelling in the sub-arctic ocean gyre is expected to result in an increase in expression in gen...
