Summary
|
Abstract:
This dataset consists of analyses for dissolved sulfate and ammonium done on pore water samples extracted from sediment cores. In addition, most of the sediment samples have been analyzed for organic carbon content of the dry sediment. The sediment cores were collected during research cruises conducted by, or for, the Geological Survey of Canada (Atlantic) at more than 35 field study locations around the world.The data are used to determine the change in concentration with depth (concentration gradient) in the core for sulfate and ammonium. From this concentration gradient, an empirical relationship is used to estimate organic carbon burial at that location. Finally, knowing the organic carbon content of the sediment at that location, an estimate of sediment accumulation rate can be made.
