    dct:description "This dataset contains vertical profiles of soil bulk density, percent organic matter, percent total carbon  and cesium-137 activity from the surface down to 50-60 cm deep at 25 marsh locations across Breton Sound basin, Louisiana. These data will provide information related to rates of vertical accretion, organic and mineral accumulation and carbon burial in wetland soils across a large portion of the Mississippi River delta plain." ;
