SBC LTER: Reef: Surge uptake capability in Macrocystis pyrifera in response to pulses of three different forms of nitrogen

This data describes the capacity of the giant kelp, Macrocystis pyrifera to exhibit surge uptake of three different forms of nitrogen in whole-blade incubation experiments done in spring and summer 2019. The data is contained in 2 tables: 1) uptake rates of 15N labeled nitrate, ammonium, and urea by blades exposed to pulses of nitrogen for periods lasting 1, 5, 15 and 45 min, 2) uptake rates of 15N labeled nitrate, ammonium, and urea for specific time intervals of pulsed nitrogen (e.g., 0-1 min, 1-5 min, 5-15 min and 15-45 min).
