| Abstract: | Nutrient data was collected 6 times between April 1999 and April 2002 by MBL All samples were collected over a two day period. Samples were analysed for NO3, NO2, NH4, PO4, Cl, SO4, and K at MBL. Headwater stream sites included a range of land uses in the contributing area. This file duplicates data in the file WAT-IP-catchments in order to standardize station ID among different sample periods, and is consistent with the ID's in WAT-UNH-IP-catchments. To cross reference between these two data files see "Lab_ID's" for April 2000 in the data file "WAT-IP-catchments.". | |||||||
