B. Water level and salinity.

Salt marshes are marginal wetlands that are overflowed and dumped by salt water produced in by the tides. They are marshy because the loam may be formed of deep mud and peat. Peat is made of decomposing plant material that is often various feet deep. However, Water level and salinity are the two properties which fluctuate in salt marsh.

B. oceanic & neritic
