**Acknowledgements**

The authors are grateful to the Tertiary Education Fund (TETFUND) under the Federal Government of Nigeria and Surveyor Registration Council of Nigeria (SURCON) that provided the funding for this research. Thanks to Professor Andrew Manning for his consistent encouragement and effort to ensure that this research is published. Dr Victor Abbott and Prof. Richard Whitehouse are commended for their kind assistance while the research was on-going.

Prof. Manning's contribution towards this research (book chapter) was made possible in part by a grant from The Gulf of Mexico Research Initiative (CSOMIO: Consortium for Simulation of Oil-Microbial Interactions in the Ocean) and in part by the US National Science Foundation under grant OCE-1736668 and HR Wallingford company research FineScale project (ACK3002\_62). Data are publicly available through the Gulf of Mexico Research Initiative Information & Data Cooperative (GRIIDC) at https://data.gulfresearchinitiative.org (DOI: 10.7266/n7-0sht-6s68).

The authors wish to thank Dr Leiping Ye for his kind assistance with the data archive uploading.
