    Qualifications

    PhD degree in Geophysics/Hydrogeophysics or relevant field (eg. Physics, Engineering or similar discipline) from a renowned institution/university

    Preference

    • Background in electrical or electromagnetic methods, previous experience in transient electromagnetics is an advantage.
    • Significant background in programming and numerical modelling. Matlab and fortran experience are preferred.
    • Long record of geophysical field work and working with field data.
    • Strong organizational skills, previous project management experience is preferred.
    • Applicant must have written several scientific papers and have significant experience presenting scientific results at conferences and meetings.

    The project also requires that the applicant be willing to participate in international field campaigns (likely in sub-Saharan Africa) that will last ~1 month in duration and that could occur twice per year.

    Responsibilities/ Job Description

    Groundwater is an integral part of satisfying global water needs, often representing a water source at lower contamination risk than surface water. Yet, proactive management practices must be implemented to ensure long-term sustainable use of groundwater resources, as overexploitation can deplete groundwater reserves – effectively supplying a short-term fix to problems requiring long-term solutions.

    A key component of informed data-driven management practices is high-resolution characterization of hydrogeological systems, a step that can be well-addressed through the use of non-invasive geophysical techniques. Transient electromagnetics (TEM) is particularly adept at rapid cost-efficient mapping of geological systems. TEM systems can be man-deployed or towed by an ATV or aircraft, each system with their respective advantages and disadvantages. However, standard TEM mapping practices are generally focused on spatial characterization – producing snap-shots of hydrological systems at an instant in time. This information is extremely valuable when populating groundwater models or characterizing groundwater systems but can often leave uncertainties as to the behaviour of groundwater systems over time.

    A primary focus of this postdoctoral project will be the development, field validation, and deployment of monitoring TEM systems designed for long-term deployment, autonomous operation, and data-streaming to remote servers. This work will involve coupling numerical studies focused on time-lapse inversion of TEM data, assistance with instrument testing/validation, and field data collection where long-time series will be collected in locations of dynamic groundwater systems. Monitoring TEM systems will be deployed in multi-year campaigns in both Denmark and internationally.

    A second focus of this project is the support of parallel semi-airborne TEM system coupling groundbased transmitters with a roving drone-carried receiver. This work will involve supporting drone-based mapping campaigns and subsequent data workflows, including signal processing, inversion, and interpretation of results. Validation of semi-airborne systems will also require the applicant to participate in comparison studies with complementary TEM systems (eg. the towed transient electromagnetic system tTEM).

    The applicant will also be required to play a significant project management role in the Innovation Fund Denmark project titled SuperTEM, coordinating between partners, overseeing project meetings, and tracking progress towards project milestones/deliverables.
