sediment carbon

Abstract

Concentration of organic carbon from CHN analysis of sediment samples collected by box core from sites in the North Sea during three Cefas cruises on RV Corystes (Cruise Codes CORY 10/2001, CORY 09/2002 and CORY 8x/2003). Cores were sliced into 1cm samples at a range of depths from 0-17cm. These have been used to summarise profiles and describe spatial variance within four Ecohydrodynamic Units (EHUs).

Quality and validity

Lineage

Samples were screened at 2mm and the <2mm fraction was then freeze dried, homogenised, and treated with sulphurous acid to remove inorganic carbon (carbonates). Organic carbon was determined by flash combustion. Organic carbon levels in the sediment indicate the amount of organic matter supplied to the bed and how rapidly it is decomposed, i.e. it reflects the balance between input and respiration/burial. Organic carbon content of sediments is also related to eutrophication and biodiversity due to the relationship between the recycling of organic matter and the availability of oxygen.
