Alternate Identifier:DOI PLACE HOLDER
Abstract:

Detailed surveys of stream nitrate concentrations in the calcium-enriched (W1), hydrologic reference (W3), and biogeochemical reference (W6) watersheds were performed in the summer of 2015 with the goal of identifying "hotspots" of NO3- inflows into streams.

Methods and protocols used in the collection of this data package
Description:

In each watershed, a measuring tape was run along the stream channel and measurement locations were flagged approximately 50m apart, starting at the weir of the waterhsed and moving upslope. (In WS1, reach 11a corresponds to an in-between sampling point that was later added because it was determined that there was a seep entering at this location which was extremely rich in NO3.) In the event of a fork in the stream, the main stem of the stream was followed, as determined by greater upslope accumulated area. For each survey, unfiltered grab samples were taken at each sample point, starting at the weir and continuing upstream until first flowing water. Samples were immediately analyzed in the field using a SUNA optical nitrate sensor (Seabird Scientific, Halifax, NS) which had parafilm wrapped around the optical path to create a sample cell. Discharge at the weir for each sampling time was calculated using the USFS 5 minute stage data and a rating curve created from the historical stage and discharge data. If no time wasrecorded for a survey, the average discharge over the interval of 8 AM to 12 PM is reported here, as these surveys took place in the morning according to field notes. Units: Liters per second. Discharge at each sampling point was calculated by multiplying the discharge at the weir by the proportion of the watershed drained by the stream at each sampling point.
