  • a Data from 2004 were collected during sampling for molecular analyses. Data from January 2003 are presented as the range of values observed from 14 to 23 January 2003; each site was sampled every 1 to 3 days during this period (five times in total) and once in October 2003 for analysis of NH4+ concentrations only.
