Developing best practices for measurement of oceanic 15N2 fixation rates and relationships to communities – PIs: Angelicque White (Oregon State Univ.), Pia Moisander (UMass Dartmouth), Julie Granger (Univ. Conn.)
Objective: Using field and laboratory data from a recently funded NSF EAGER award, this working group will conduct a thorough assessment of the 15N2 tracer incubation method (accuracy, error analysis, detection limit, etc.) for measuring nitrogen fixation rates and accompanying molecular methods that identify responsible diazotrophs.
