Title:
|
October 2001 water column particulate carbon and nitrogen concentrations for Georgia Coastal Ecosystems LTER sampling sites
|
Abstract:
|
Water samples were collected from the surface and the bottom of the water column at ten GCE-LTER sampling sites and from the surface of the water column during six transect surveys along the Altamaha River in October, 2001. Samples were taken at various times of day and under various tidal conditions. The particulate matter was separated by filtration and analyzed for elemental carbon and nitrogen content by CN analysis. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.
