  • Methods
    Sampling Description
    Two plots were designated in each mangrove site, which where subdivided into four subplots. In the middle of each subplot porewater samples for nutrient and sulfide analyses were collected repeatedly over 14 years next to physical data. The null hypothesis is that there is no difference between the six mangrove sites that were monitored. Two (20*20 m) plots per site in the mangrove forest are divided in four 10*10 m subplots, samples are taken in the middle of each subplot. Porewaters are sampled and physical data are measured 2-3 times a year in the middle of each subplot.

    Method Step

    Description
    Porewater samples were taken with a porewater sipper in the middle of each subplot. Sulfide samples were preserved in the field with a buffer solution and analyzed in the lab using a standard curve and a voltage meter connected to an Orion sulfide probe. Concentrations of orthophosphate, ammonium, nitrite and nitrate were determined using either a spectrophotometer, a Lachat auto analyzer or an OI analytical auto analyzer. Apha standard methods (1992) were used to derive the nutrient concentrations.

    Instrumentation
    YSI voltage meter and sulfide probe spectrophotometer OI analytical auto-analyzer Lachat auto-analyzer

    Quality Control
    Dataset QA/QC performed during analysis of samples; samples with 5% between lab replicates were redone; data is graphed to check for outliers and checked by second scientist
