Miss Adeline Marie Dutrieux is a Postgraduate research student within Ocean and Earth Science, National Oceanography Centre Southampton at the University of Southampton.

2009-2012: BSc in Geology at the University of Liège (Belgium).

2012-2014: Master degree in Geology-Geochemistry at the University of Liège (Belgium). Received the Master Award with the highest honours (la plus grande distinction).
She did her Master’s thesis on Argon dating of volcanic rocks, supervised by Dr J. Vander Auwera (ULg). The title is : “A detailed geochronological 40Ar/39Ar study of three Chilean Volcanoes: Calbuco, Osorno and La Picada.”
She realised her analyses during an Erasmus internship at the Ar/Ar laboratory at the Geological Survey of Norway (NGU, Trondheim), supervised by Dr M. Ganerød in 2014.

2014: ECORD Summer school at Marum (Centre for Marine Environmental Sciences and IODP Core repository), University of Bremen (Germany): Subseafloor Biosphere: Current Advances and Future Challenges.
2015: Started a PhD at the University of Southampton, based at the National Oceanography Centre, supervised by Dr Anna Lichtschlag and Dr Bramley Murton. She takes part in demonstrating Earth Materials and Magmatic and metamorphic petrology for 1st and 2nd years undergraduates, as well as bathymetry data analyses.
2016: On board the R/V Meteor (5 weeks; as pore waters geochemist; P.I. Dr S. Petersen) and RRS James Cook (7 weeks; as sediment and rock geochemist; P.I. Dr B. Murton) on the TAG Hydrothermal Field (26°N on the Mid-Atlantic Ridge) for the EC-funded project Blue Mining.
2017: Joins the mentors group for the MOOC Explore Our Oceans run by the University of Southampton.

Research interests

Research project: How do extinct seafloor massive sulphide (SMS) deposits evolve after hydrothermal fluid flow ceased?

My project is to look at the hydrothermal sediments overlying over, and in the vicinity of, the seafloor massive sulphides (SMS) and investigating the reactions occurring within the sediments. These hydrothermal sediments, or metalliferous sediments are characterized by a high content in metallic particles, especially Fe and Mn oxy-hydroxides. They are accumulated by different processes such as mass wasting (turbidites flows or collapses) of chimneys materials and massive sulphides, and hydrothermal plume fallout settling in the pelagic sediments. Following their deposition, they undergo diagenetic processes defining redox zonation and remobilising redox-sensitive metals. In some cases, if a low-temperature hydrothermal fluid flow is passing through, they undergo authigenic mineralisation. The different analyses I have/will encounter(ed) are: ICP-MS, ICP-OES, XRD, XRF Itrax core logging, SEM, Ion chromatography, photo-spectrometer, biostratigraphy.

My study is on the hydrothermal sediments from the TAG Hydrothermal Field on the Mid-Atlantic Ridge, 26°N, that I collected in summer 2016 by gravity coring (mainly), HyBIS grabbing, mega-coring and rock drilling. I am focusing on the low-temperature hydrothermal zones and the relict hydrothermal mounds environments. This project is involved in the larger EC-funded project Blue Mining which its overall objective is to provide breakthrough solutions for sustainable deep-sea mining.
