PhD studentship at University of Exeter (Camborne School of Mines)

NERC Oil and Gas CDT PhD Studentship: Lower Jurassic Source Rocks in Germany/Netherlands or Mudrock Petrography Using Advanced Electron Beam Techniques

One PhD studentship in the NERC Centre for Doctoral Training in Oil & Gas is available at the University of Exeter Penryn Campus. The fully funded studentship will be awarded for one of two possible projects: Lower Jurassic Source Rocks in Germany/Netherlands or Mudrock Petrography Using Advanced Electron Beam Techniques.

 Project 1. Lower Jurassic Source Rocks in Germany/Netherlands.

Secondary supervisor:  Dr Stuart Robinson (University of Oxford)
The pattern of Early Jurassic ‘black shale events’ that relate to global perturbations to the carbon cycle is becoming quite well known for the Early Jurassic, where several such events have been described from NW Europe basins and elsewhere.  What is much less well known is how these black shale events relate to regional or global sea-level changes, and the effects of basinal tectonics and palaeogeography on organic matter enrichment and quality within individual basins.
This project take takes advantage of extensive industry core and geophysical data from the Lias of Germany and the Netherlands.  The student will integrate the available data and set the black shale occurrences within an overall framework of basin evolution to determine the fundamental controls on local organic enrichment.  Detailed chemostratigraphic, petrological (SEM, EDS), and organic geochemical studies will be undertaken, in addition to working with wire-line log and seismic reflection datasets, in order to arrive at an interpretation across the complete range of observational scales.
The student will be part of a larger team of industry-funded researchers working on diverse aspects of mudrock science, both at the Oxford and Exeter, and will benefit from access to state-of-the art analytical and imaging facilities at both institutions.

Project 2. Mudrock Petrography Using Advanced Electron Beam Techniques.
Secondary supervisor:  Dr Ian Bailey
Textural and compositional characterisation of mudrocks is of considerable importance in understanding conventional and unconventional source rocks and cap rocks.  However, existing methodologies all have limitations.  Whilst whole rock mineralogy is determinable through XRD there is a lack of textural data.  Microscopy allows textural characterisation, yet determining the mineralogy may be impossible.  Manual SEM and TEM studies typically only derive datasets for very small areas.  Advances in automated SEM-EDS analysis are challenging some of these limitations.  New software algorithms allow very detailed mineralogy to be automatically mapped, whilst in parallel capturing textural data.  By integrating automated mineralogy and backscatter image, mapping the distribution of organic components will also be achievable.
In this studentship, the primary aim will be to test the application of advanced automated SEM-EDS analysis in the characterisation of mudrock mineralogy and texture.  Initially synthetic standards will be created to allow instrument calibration and reproducibility to be measured.  Then suites of mudrocks with different source areas, diagenetic pathways, burial histories, and maturation characteristics will be quantified, and the data obtained through automated mineralogy compared with traditional methodologies.  The studentship will result in the development of these new instrumental approaches to characterising mudrocks.  This will be highly original work at the forefront of new instrument development and will result in international journal publications.  The project will be undertaken with significant scientific input from Duncan Pirrie (Helford Geoscience LLP).

Two PhD scholarships at the University of Wollongong, Australia

Coastal wetlands: are our valuable carbon sinks vulnerable?
Saline coastal wetlands in southeastern Australia are located within the intertidal zone of estuaries and are particularly vulnerable to decline in quality and extent with changing water levels. These wetlands provide many ecosystem services including coastal protection and carbon sequestration. Hence, coastal wetlands both mitigate climate change and promote adaptation to climate change. A recently awarded ARC Future Fellowship has provided an opportunity for two PhD candidates to be part of a team of researchers at the University of Wollongong, led by Dr Kerrylee Rogers to explore the vulnerability of coastal wetland carbon sinks. The proposed project will use isotopic tracers to quantify carbon retention and flux, sedimentation and surface elevation change within coastal wetlands in southeastern Australia.

The research will integrate field work and laboratory analyses with geospatial analyses. Candidates with a background in coastal and estuarine processes, isotopic dating, stable isotope analysis, statistics or geographic information systems are sought.

The PhD scholarships are available in the School of Earth and Environmental Science and are associated with ARC Future Fellowship FT130100532. The 2014 full-time stipend rate is $25 392 pa tax exempt for 3.5 years.

Interested applicants should initially send a cover letter and CV to Dr Kerrylee Rogers (Kerrylee@uow.edu.au). Applicants will also need to complete a candidature/scholarship application form and arrange two academic referee reports to be submitted to the Student research centre by 12 March 2014.

PhD studentship in Basin analysis, Université Toulouse, France

Source to sink and vertical movements of the Mozambique Channel: Morondava Basin (Madagascar)

Within the framework of the PAssive Margin Exploration LAboratory (PAMELA), and the study of the Mozambique Chanel (Morondava Basin, Madagscar), the aim is to understand the evolution of a continental margin using an integrated source-to sink approach. 
Three main research objectives are: (1) the identification of the preserved geomorphologies and structural features of a rifted pull-apart basin, (2) the quantification of the vertical movements from rift to the drift sequence and the Neogene reactivation in relation with the East Africa Neogene rifting, and finally (3) the identification of the isotopic signature of the sediment to trace their sources. This approach will be discussed with the evolution of the conjugated margin (Tanzania-Somalia) to build a genetic model for the evolution of rift and the erosion of its margins.
Candidates should have a master degree or equivalent in geosciences. Basin analysis skills are highly recommended. Field work and research oceanographic cruise experience is an advantage. The candidate should be literate in subsurface interpretation and GIS. Laboratory experience in analytical isotopic geochemistry is an advantage, otherwise training will be provided. Works will include participation to an oceanographic cruise in the fall 2014 and a field campaign in early 2015. The student will be registered at the Université Rennes 1 and the position will imply mobility during the 3 years between Rennes, Toulouse and Pau.
Financial support is granted within the frame of the PAMELA project (IFREMER – TOTAL).
To apply for this position please send your cv and a cover letter to Dr Cécile ROBIN (cecile.robin@univ-rennes1.fr) and Dr Gérôme CALVES (gerome.calves@get.obsmip.fr).
The position will remain open until a suitable candidate has been found.

PhD project on submarine landslides at GEOMAR Kiel, Germany

Topic for a PhD project in the Cluster of Excellence “The Future Ocean”, Kiel, Germany.
Is the loss of sediment structure responsible for large submarine landslides at open
continental slopes?

Submarine landslides, or the gravity driven down-slope movement of material, represent the
largest mass flows on Earth. Historically, these landslides have caused devastating tsunamis, broke seafloor communication cables and seriously damaged offshore hydrocarbon exploration  infrastructure. The scale of submarine landslides can exceed terrestrial events by two orders of magnitude. For instance, the Storegga Slide offshore Norway affected an area larger than Scotland  and moved sufficient sediment to bury this area to a depth of 80 m. Remarkably, these events typically occur on nearly flat slopes of ~2° or even less, which makes them difficult to explain. For particular continental slopes with comparatively high sedimentation rates failure could be explained by high excess pore pressures due to rapid deposition and/or lateral fluid transfer. However, large submarine landslides also occur in areas where sediment accumulation is slow. Preliminary modelling shows that a zone of high compressibility is one way to cause slope instability in such settings. Stress-induced rapid loss of structure, which allows the sediment to maintain high porosity initially and is caused by inter-particle forces and the geometrical arrangement or fabric of the  particles, may provide such high compressibility. This project aims to test this hypothesis by examining the mechanical behaviour of deep sea sediments and developing numerical models incorporating resultant sediment behaviour. We wish to understand how and why structure develops in marine sediments, and whether rapid loss of this structure can promote slope failures in locations worldwide. This will directly feed into the broader research direction “Dangerous Ocean” which is part of the excellence cluster “Future Ocean” ensuring that the results of the thesis are disseminated and become visible.
The main part of the project will use geomechanical modelling to explore the role of destructuring on the stability of continental slopes. The candidate will set up finite element models of continental slopes including layers of structured sediment using the commercial software package ABAQUS. The constraints and input parameters will be assembled from existing geotechnical and sedimentological data sets. Down-core Scanning Electron Microscopy imaging and petrographic microscope analysis (perfomed pre- and post-testing) will be used to investigate the onset of destructuring, and to characterise loss of structure with increasing burial depth in IODP cores. In addition, the candidate will analyse oedometer as well as direct and cyclic shear test data from a variety of sources to determine the degree of structure of various deep sea sediments. In this respect the project benefits from a close collaboration with Fugro GeoConsulting Limited, who perform engineering geological, geohazard and geotechnical appraisals for offshore oil and gas developments.
Hazard assessments for submarine landslides are difficult to quantify, mainly because the reason(s) for submarine slope failure are contentious. The project has the potential to significantly advance the current understanding of these reasons. Hence, this research may help to identify hazardous areas of potential future landslides, to protect the increasing population in coastal areas and increase safety of the new ventures in offshore human activities as a response to the growing demand on resources. The development of robust testing methodologies that can be used to inform credible, forward looking geohazard analyses will provide valuable tools for the offshore industry as a whole.

Training opportunities:
The project will be will be based at the GEOMAR Helmholtz Centre for Ocean Research Kiel, one of the leading marine research institutions in Europe and the world. The successful candidate will enroll in the Integrated School of Ocean Sciences of the Cluster of Excellence Future Ocean, where they will have access to a full range of research and generic training opportunities that are aimed to support the development as an independent researcher. The integrated geotechnical, sedimentological and numerical approach of this project leads to training over a wide range of methods and techniques, including soil mechanical principles required to understand and interpret geotechnical test results, geological datasets from the present-day ocean floor, and numerical modelling. This broad approach gives the doctoral candidate a solid base for a further career in either academia or industry. The candidate will have the opportunity for a short-term placement at Fugro GeoConsulting Limited in Wallingford to work on industry data to provide broader industry context for the study. The candidate will gain important international experience through frequent visits to the UK partners.

Essential skills: Numerate with a good degree in Earth Sciences or Geotechnical Engineering.
Desired skills: Experience in geotechnical testing and data analysis, numerical modelling, knowledge of FORTRAN.

PhD Opportunities at National Oceanography Centre Southampton, UK

Exciting New PhD Opportunities at NOC Southampton - Turbidity Current Hazard Assessment
This is a chance to be part of one of the largest graduate schools in the UK, in a rapidly expanding research group, and to provide some crucial new information for industry - as well as develop the understanding of submarine sediment density flows.
National Oceanography Centre Southampton (NOCS) is advertising for a PhD student to investigate how turbidity currents interact with the seafloor and oil and gas pipelines. Turbidity currents pose a credible threat to offshore infrastructure but due to the difficulties in obtain direct measurements in the deep sea, understanding their character is a major scientific challenge.
Full details on the project can be found at: http://noc.ac.uk/gsnocs/project/understanding-how-turbidity-currents-interact-seafloor-oil-gas-pipelines
Applications for PhD projects should be via http://noc.ac.uk/gsnocs/how-apply.
A numerate candidate is sought from disiplines such as Civil Engineering, Geology, Geophysics, Mathematics and Physics.The project will combine novel experimental techniques (electrical resistivity tomography), sediment core analysis and geotechnical testing to assess scour potential and provide direct input to existing numerical hazard models. This will provide key information for quantification of impact stresses exerted on seafloor structures.

In addition to the individual training provided at NOCS each CDT student will undertake a 20-week high quality training package, with each student benefiting from a rich cross-consortium teaching experience (see http://www.pet.hw.ac.uk/research/nerc-cdt-oil-gas-academic-partnership.htm for further details of consortium partners), conferences and fieldtrips for the entire CDT cohort and industry placements. The project also benefits from close collaboration with Fugro GeoConsulting Limited.

The multidisciplinary approach leads to training over a wide range of methods and techniques, including soil mechanical principles required to understand and interpret geotechnical test results, geological datasets from the present-day ocean floor, sedimentological field work, and experimental modelling. This broad approach gives the doctoral candidate a solid base for a further career in either academia or industry.
