Abstract:

Denitrification and nitrogen cycling processes were measured from marsh sediments to determine the impact of oiling on salt marsh ecosystems. Five replicate sediment cores were collected from vegetated marsh and intertidal habitat and incubated for a 24 hour period to examine denitrification and nutrient fluxes using the isotope pairing technique. Data were collected three times in both summer and fall of 2015.

Purpose:

The purpose of this study was to investigate the denitrification rates in marsh and subtidal habitats that were previous exposed to moderately oiled sediments.
