Sediment samples were collected at the surface and bottom (N50 cm) layers with an auger.
However, in 2010, only surface samples were collected at Site 1 due to flooded conditions and in
2013 and 2014, the sediment at Site 3 was totally submerged within the quadrats; therefore, drier
soil samples adjacent to the mangrove quadrats were augered in addition to submerged samples
within the quadrats. In this study, three replicates were taken per quadrat at each of the four sites.
The sampleswere stored in plastic bags for transportation to the laboratory for analysis.
