This data set is associated with the manuscript draft entitled "How is particulate organic carbon transported in the Congo-River-fed Submarine Canyon to the deep-sea"? accpeted for publication in the Journal EGU Biogeosciences on 18 August 2024. The dataset includes grain-size measurements, total organic carbon contents, carbon stable isotopes and radiocarbon ages on sediment samples collected in a sediment trap and multi-cores in the Congo Submarine Canyon at 2 km of water depth.  Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

Sediment Traps in the frame of HERMES project

The database presents the field data used within the study carried out in the north-western Adriatic Sea (Brigolin et al., 2018, Biogeosciences https://doi.org/10.5194/bg-2017-206). A longline mussel farm was taken as a local source of perturbation to the natural Particulate Organic Carbon (POC) downward flux. This flux was first quantified by means of a pelagic model of POC deposition coupled to sediment traps data, and its effects on sediment bioirrigation capacity and OM degradation pathways were investigated constraining an early diagenesis model by using original data collected in sediment porewaters. The measurements were performed at stations located inside and outside the area affected by mussel farm deposition.
