Abstract:

This dataset contains soil carbon and nitrogen content data obtained from salt marsh cores collected in northern Barataria Bay, Louisiana from 2011-10-20 to 2016-10-25. Soil cores were collected from the top 15 cm of soil using a 5 cm diameter by 50 cm long semi-cylinder peat corer from each of 21 sampling sites representing a range of oiling conditions: heavy oiling (n=7), moderate oiling (n=7), and no oiling as a reference (n=7). All soil cores were initially dried to a constant mass at 60 C and weighted to determine the bulk density (g/cm3). Dried soil samples were ground to a fine powder first using a mortar/pestle and then with a ball mill grinder. Dried samples from each site were then weighed into small aluminium weigh dished and analyzed for total carbon (%) and nitrogen (%) content using an Elemental Combustion System.

Purpose:

To determine the long-term impacts of Deepwater Horizon on salt marsh soil carbon and nitrogen content.

Data Parameters and Units:

Sampling Date [MM/DD/YYYY]; Oiling Category [Reference (n=7), Moderate Oil (n=7), Heavy Oil (n=7)]; Treatment ID [RF, MD, HV]; Station ID; Latitude and Longitude [Decimal degrees]; Total Soil Carbon [%]; Total Soil Nitrogen [%]; Soil Bulk Density [g/cm3].

Methods:

Soil cores were collected yearly from each of the 21 sampling sites in October/November of 2011 to 2016 from the top 15 cm of soil using a 5 cm diameter by 50 cm long semi-cylinder peat corer. All soil cores were initially dried to a constant mass at 60 C and weighted to determine soil bulk density (g/cm3). Dried soil samples were ground to a fine powder first using a mortar/pestle, and then with a ball mill grinder. Dried samples from each site in each collection year were then be weighed into small aluminium weigh dished and analyzed for total carbon (%) and nitrogen (%) content using a Costech 4010 CHNS/O Elemental Combustion System.
