Abstract:

This dataset investigates the biodegradation of oil, dispersant, dispersed oil or dispersed oil and nutrients at the molecular level using ultra-high resolution Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). This dataset was generated through laboratory microcosm experiments using amended water collected from a natural hydrocarbon seepage area at ~1200m depth.

Purpose:

The purpose of this dataset is to address the molecular compositional changes of the water accommodated fraction (WAF) of oil during biodegradation in more detail aiming to answer the following questions: How does the application of dispersant influence the biodegradation of individual compounds in the WAF of oil? Which oil- and dispersant-derived compounds are degraded and which accumulate in the DOM pool?
