The hydrogeochemistry of nine streams in the Caribou-Poker Creeks Research Watershed (CPCRW) during the summers of 2002 – 2006. In summer 2005, Boston Creek, which is located ca. 20 km east of the CPCRW was sampled. The Boston Creek watershed was extensively burned during the Boundary Fire of 2004. Samples were analyzed for Ca, Mg, Na, K, NH4+, Si, Cl, NO3, SO4, DOC, TDN, DIC, SUVA, pH and conductivity.

Access to Data
While metadata will be freely available to those requesting it, the data manager will assure that any restrictions on access to data sets in the database will be enforced. Data will not be released without proper permission first being obtained from the investigator who generated the data.
Use of data
Researchers should receive adequate acknowledgment for the use of their data by others and should be provided with copies of publications using their data. Users of data from the data base must be aware that data is not to be sold or redistributed.
Citing Bonanza Creek LTER Datasets
It is considered a matter of professional ethics to acknowledge the work of other scientists. Thus, the Data User will properly cite the Data Set in any publications or in the metadata of any derived data products that were produced using the Data Set.

Experimental Design
Stream chemistry is monitored in headwater and higher order streams that drain watersheds with varying permafrost extents to examine the coupling between permafrost thaw, watershed hydrology, and stream exports. Headwater streams drain watersheds with permafrost extents ranging from 4 - 54 %.
Methods
FIELD: The chemistry of streams was sampled at intervals from daily to bi-weekly and analyzed for major ions and other solutes. Daily samples were collected with autosamplers. Each daily sample collected by autosamplers was a composite of samples collected at 6 pm and 6 am the following day. LAB: Anions (Cl, NO3, SO4) and cations (Ca, Mg, Na, K, NH4+) were analyzed by ion chromotrography. DOC and TDN were measured using a Shimadzu TOC-5000 plumbed to an Antek 7050 nitric oxide detector to quantify total dissolved nitrogen. DIC was measured as inorganic carbon using a Shimdzu TOC-5000. SUVA was measured by the absorbance at 254 nm and was standarized to the DOC concentration.
