EXPERIMENTAL DESIGN AND METHODS:  Sediment collection plates (4x4 inch plexiglass square with a 90 mm GFF attached to surface) were placed flush on the marsh surface along each transect for one week. The plates were collected and replaced approximately once a week for four weeks.  The filters were removed from the plexiglass, dried, and weighed.  The total sediment deposited is determined by subtracting the filter weight from the total dry weight.  The filters are then muffled in a 550 C muffling furnace for two hours.  The inorganic component weight is found by subtracting the filter weight from the muffled weight.  

NOTES AND COMMENTS: At each station along each transect, two samples were collected (A and B).

Sediment After Mufflng

Inorganic Sediment amount per unit area of filter per week

CALCULATIONS: 

Sediment after muffling = ((Muffled Weight (g) – Filter Weight (g))*100 mg/g)/Area of filter (cm2)/day *7)  Reported as mg/ cm2  /week

(NOTE: Many of the final values are negative due to the breakdown of the filters in the field.  Hence, all of the values can only be used to look a relative relationships.)
