Bioturbation in seabed sediments results from feeding, burrowing and habitat construction by benthos. It can substantially modify the physical, chemical properties of sediments, distort or smear primary stratigraphical signals, influence the early diagenesis, sedimentary record and stability of sediments. Research on bioturbation is very important to roundly and exactly understand the processes of biogeochemical cycles in marine sediments, accurately reconstruct the records of palaeogeography, palaeoclimatology and palaeoecology, reasonably adjust and control the biodiversity of seabed ecosystem. This paper briefly reviews the development of the research on bioturbation in marine sediments, and focuses on comments of the observation and quantitative research methods of biotutrbation, its major influential factors, and its effects on sedimentary processes and records.
