Time series of tracer (Rhodamine WT) concentration data representing a "break-through curve" resulting from a stream tracer injection. Stream tracer experiments were conducted in the lower reach of 2nd-order Watershed 3 in April, 2001, and 2 adjacent reaches of 4th-order Lookout Creek in July, 2002. Rhodamine WT dye was injected as a pulse (non-continuous injection). Concentration data were collected in the field at early time using a field fluorometer equipped with a flow-through cell. Late-time samples collected with an ISCO auto sampler, which were analyzed in the lab with the same fluorometer (reconfigured for analysis with cuvettes) within 72 hours. Particular care was taken to collect late-time, low-concentration data, which are useful in quantifying the residence time of secondary storage within or adjacent to the stream, such as the hyporheic zone or in-stream transient storage zones. In the data set, Tracer 1 refers to the injection in Watershed 3; Tracer 2 refers to the injection in Reach 411 of Lookout Creek; Tracer 3 refers to the injection in the combined Reach 410/411 of Lookout Creek.

Description

• An update history is logged and maintained with each new version of every dataset.

Change History

• Version1 (2002-12-04)
  Original metadata creation.
• Version2 (2002-12-18)
  Metadata restructured and moved into SQLServer metadata database LTERMETA. Data moved into SQLServer database FSDBDATA.
• Version7 (2016-12-20)
  Need to upload dataset to PASTA. There are 8 entities that were prepared back in 12/18/2002. However, these entities could be combine into 1 dataset with the given distinctions (reach,series,test). These entities were combined to upload to PASTA. Because of the connections to catalog_request_history, entities 2-8 cannont be deleted. These have been designated as not online. Data QC'd. Old SQL structures deleted and new one created. Appended data into the one new entity.
