  • Methods
    Sampling Description
    Two plots established in each mangrove site and then subdivided into four subplots. In the middle of each subplot physical data were collected every 4-6 months over 20 years. The null hypothesis is that there is no difference between the six mangrove sites included in the study. two (20 x 20 m) plots per site in the mangrove forest are divided in four 10 x 10 m subplots, samples are taken in the middle of each subplot. All plots contain mangrove trees; plots are flooded semi-diurnally. Physical data are measured 2-3 times a year in the middle of each subplot where porewater samples for nutrient analyses are also obtained. 230 is added to the field redox reading to get redox potential (Hargis, Thomas G. and Robert R. Twilley. 1994. Multi-Depth Probes for Measuring Oxidation-Reduction (Redox) Potential in Wetland Soils. Journal of Sedimentary Research A64: 684-685.)

    Method Step

    Description
    Physical data were measured in the field with a YSI, redox probes and a pH probe attached to a voltage meter.
