EXPERIMENTAL DESIGN AND METHODS:

Triplicate 9 cm diameter glass fiber filter circles were placed on inverted petri-dish tops and fixed to the marsh surface with a long nail at each station. Filters were then collected after 2-5 weeks and dried. Sedimentation rates were measured as the weight change of the filter before and after deployment. A sub-set of filters were ashed to determine organic content of the accreting sediment. Relative elevation of the sites were determined by near-simultaneous water depth measurement at slack high tide.

NOTES AND COMMENTS:

VARIABLE DESCRIPTION:

STATION - transect station

STATE X = x coordinates (meters) in MA state plane NAD 83

STATE Y = y coordinates (meters) in MA state plane NAD 83

LAT = Latitude in NAD 83 geographic coordinates (decimal degrees)

LON = Longitude in NAD 83 geographic coordinates (decimal degrees)

DIST = Distance from creek bank (m)

ELEV = relative elevation of the marsh surface (cm)

VEG = dominant vegetation type (alterniflora = Spartina alterniflora; short alterniflora = Spartina alterniflora short-form; patens = Spartina patens)
DEPLOY = date of filter deployment

COLLECT = date of filter collection

SED = sedimentation rate (g m^-2)

SED SE = standard error of the sedimentation measurement

%OM = percent organic matter of sediment of filter
