Abstract:Nutrient data set of Ipswich River tributaries located in first- (F) and second- to fourth-order catchments (referred to as nodes - N). Data are for base-flow conditions (BASE) in all but the April 2000 set which was a storm event (EVENT). Samplings occurred from April 1999 to September 2000 and were collected and analyzed by MBL.
