NEON prototype reaeration data from Blue River (BLUE), 2016

This data package contains data from a modified version of NEON's wadeable stream reaeration sampling protocol.
Due to high discharge and large stream width at BLUE, there was concern that the typical NEON reaeration protocol (NEON.DOC.000693) would require a large amount of salt and wouldn’t allow for sufficient mixing across the stream. This led to the trial of a reaeration bout in August 2016 with the following modifications to the regular protocol:
1. No continuous salt injection was conducted.
2. Discharge was taken at each of the 4 sampling stations to assess ground water inputs instead of using the conservative tracer.
3. A salt slug of NaCl was deployed at the SF6 injection site to assess travel time. Slug solution was deployed in multiple locations to aid with even mixing. 4 HOBO loggers were deployed (one at each station).
4. SF6 was deployed using 4 air stones distributed evenly across the stream.
5. Wetted widths were collected as well as depth measurements. Depth measurements were collected because back-calculating depth would be difficult with the very deep pools, and would likely not capture the more shallow areas where reaeration is occurring in this big river.
This data package includes field and external laboratory data from the modified protocol at the Blue River site.
