This data product contains the quality-controlled, native sampling resolution data from NEON's surface water chemistry sampling protocol. Subsamples are analyzed at NEON domain headquarters for alkalinity and acid neutralizing capacity (ANC); other subsamples are sent to external facilities for a broad suite of analytes, including dissolved and total nutrients and carbon, cations and anions, and general chemistry. For additional details on NEON field and laboratory protocols, see the AOS Protocol and Procedure: Water Chemistry Sampling in Surface Waters and Groundwater (NEON.DOC.002905). : Grab samples of surface water at NEON aquatic sites are collected in streams 26 times per year and 12 times per year in lakes. In streams, 12 samples are collected at regular intervals during the sampling season, while the remaining 14 are collected on an irregular basis to capture major flow events. In lakes, samples are collected approximately monthly and to capture ice-on and ice-off events. The field protocol used by NEON for collecting surface water chemistry samples follows the general requirements set forth by the 2011 USGS National Water-Quality Assessment (NAWQA) Program and the Arctic LTER standard operating procedures (SOP). Sample handling and preparation portions of this protocol follow the general requirements set forth by the USGS National Water-Quality Assessment (NAWQA) Program (USGS 2006).
