Porewater is sampled monthly from May through November and bi-monthly from December though April using diffusion samplers.  Samples are retrieved from triplicate poles at depths of 10, 25, 50, 75, and 100 cm.  Soluble reactive phosphorus, NH4, S2, and chloride concentrations are measured in each sample according to standard laboratory protocols (SRP and NH4 – Strickland and Parson (1972); S2 – Otte and Morris (1994)).   NOTES AND COMMENTS: MAR-RO-MorrisTr discontinued on 7/1/99. LTE-MP-LPP began in May 99. LTE-MP-ORT began in May 00. TYC1 and TY11 are the same sampling pole.   REFERENCE CITATIONS: Otte, M. L. and J. T.
