Nitrogen cycling processes in oil impacted salt marshes on Chandeleur Islands, July, 2015 through February, 2016

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.
