Title:

Elevation and soil salinity transects at Airport Marsh and Old Beach Road on Sapelo Island, Georgia in 2001

Abstract:

To examine the relationship between elevation and soil characteristics, I sampled two sites on Sapelo Island (Old Beach Road and Airport Marsh) in July of 2001. At each site, I collected 160 soil samples across a transect from the high to the low marsh, and surveyed the relative elevation of each sample location with a theodolite. I determined soil water content gravimetrically, soil organic content by ashing samples, and soil salinity by rehydrating dried soils, adding deionized water, measuring the salinity of the supernatant, and back calculating to the original soil water content.
