Salt-based stream discharge (DP1.20193.001)

Tracer injections of conservative salt are completed 6 times per year to capture a range of flows at NEON wadeable stream sites as part of the wadeable stream reaeration protocol. The first sampling station is located near sensor set #1 and the fourth sampling station is located near sensor set #2. Sampling stations #2 and #3 are approximately evenly spaced between sampling stations #1 and #4. The injection (drip) station is located far enough upstream of sampling station #1 that the tracer is well mixed within the stream channel for all sampling stations. Conductivity data loggers are located near sampling stations #1 and #4 to capture the rising limb and plateau (for constant rate injections) and falling limb (for slug injections) in situ conductivity values.
