This data package contains stream water chemistry measurements taken in Santa Barbara area watersheds, beginning in 2000.
This dataset is ongoing, and data will be added approximately annually. Stream water samples are collected weekly during
non-storm flows in winter, and bi-weekly during summer. During winter storms, samples are collected hourly (rising limb)
or at 2-4 hour intervals (falling limb). Analytes sampled in the SBC LTER watersheds include dissolved nitrogen
(nitrate, ammonium, total dissolved nitrogen); soluble reactive phosphorus (SRP);
particulate organic carbon, nitrogen and phosphorus; total suspended sediments; and conductivity.
There are two tables in this dataset. Samples from "registered stations" (see geographic coverage) are in
the first data table (see table name). Many other samples have been collected ad hoc, or as "stations of opportunity".
These have been collected in a second table, designated "non-registered". The station codes for these samples may
have been reused, and are not recorded in metadata (but station codes can be found in data).
