Marine Sediment Geochemistry Data (Pore Water)
Entry ID: CANEMRCCRSAGCGEOCHEM


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.
