Abstract:

Sediment characteristics were measured during a project to investigate sediment denitrification and nitrogen cycling processes. Sediments were filtered and stored on ice in the dark prior to return to the laboratory within 8 hrs. Sediment samples for chlorophyll were collected from the top 1 cm. Sediments for the carbon to nitrogen molar ratio were collected from the top 10 cm and homogenized prior to the analysis. The below ground biomass was collected from the top 10 cm of the sediments from the marsh platform. Data were collected seasonally from July 2015 to February 2016.

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.
