NERC-funded 4-year Ph.D. studentship in ocean biogeochemical modeling at the University of Oxford and National Oceanography Centre
Project title: Toward a Mechanistic Model of the Ocean Biological Carbon Pump
Supervisors: Prof. Samar Khatiwala (Department of Earth Sciences, University of Oxford) and Dr. Adrian Martin (NOC, Southampton)
Start date: October 2016.
Photosynthesis by phytoplankton at the surface of the ocean absorb CO2 from the atmosphere to produce organic matter. At the end of their life cycle these marine
organisms aggregate into large, rapidly sinking particles. This sinking organic matter is in turn fed on by bacteria and zooplankton, respiring CO2 that can stay
dissolved in the deep ocean for thousands of years. This set of processes, collectively known as the "biological carbon pump" (BCP), is a major pathway by which
carbon is transported from the atmosphere to the deep sea. Understanding the complex processes that control the efficiency of the BCP and hence the relative
partitioning of carbon between the ocean and atmosphere and, ultimately, climate, is thus one of the leading problems in oceanography and climate science. Current
models of the BCP embedded within global climate models do not however have a mechanistic representation of the BCP. They are thus largely incapable of responding
to environmental changes and cannot be used to investigate how the BCP will evolve in the future or how it may have operated in the past.
The primary objective of this project is to obtain a mechanistic understanding of the BCP and it's response to environmental conditions. To achieve this objective, a
global model that represents the process through which marine particles stick together or break apart will be developed. Starting with the growth of phytoplankton at
the surface the model will use a Lagragian, stochastic approach to explicitly simulate the main processes of coagulation and disaggregation affecting the sinking of
organic particles through the ocean. This model of particles and biogeochemistry will interact with ocean circulation as simulated by models such as UKESM. To
feasibly carry out this computation we will exploit programmable GPUs to achieve computational speedup of the model and scale it up to run in 3-d. The student will
not only lead the development of the model-acquiring training and skills in marine biogeochemistry, oceanography and high performance computing and numerical
modeling-but also perform experiments to mechanistically explore the BCP's response to climate change.
This project is funded through the NERC Large Grant Project COMICS (Controls over Ocean Mesopelagic Interior Carbon Storage: http://comics.ac.uk/). While the
student will be based at Oxford, s/he will actively collaborate with COMICS team members at the National Oceanography Centre, and other groups in the US, Germany
and France. The student will also be affiliated with Oxford's NERC-funded Environmental Science Doctoral Training Partnership (DTP) in Environmental Research and
will thus benefit from courses offered through the DTP.
Eligibility: This is an exciting opportunity for someone with a good first degree in the natural sciences, maths or engineering to work on a cutting edge problem at the
intersection of marine biogeochemistry, mathematical modeling and computer science. Applicants must be UK/EU residents and meet NERC/RCUK eligibility requirement.
Application process: To apply follow the instructions at http://www.earth.ox.ac.uk/graduate_admissions. Informal inquiries may be directed to: Samar Khatiwala
(samar.khatiwala@earth.ox.ac.uk) or Adrian Martin (adrian.martin@noc.ac.uk).

NERC Industrial CASE Ph.D. Studentship in the Department of Earth Sciences and Mathematical Institute, University of Oxford; the UK Met Office; and National
Oceanography Centre, Southampton
Title: Ocean Biogeochemical Optimisation in ESMs (OBOE)
Supervisors: Profs. Samar Khatiwala (Earth Sciences) and Coralia Cartis (Maths), University of Oxford; Prof. Colin Jones, Met Office; Drs. Andrew Yool and
Adrian Martin, NOCS
Start date: October 2016
As one of the principal reservoirs of CO2, the ocean plays a crucial role in the carbon cycle and in regulating Earth's climate. Understanding and modelling
the interconnections between the ocean carbon cycle and climate is therefore critical for robust estimates of future climate change. A principal challenge in
this regard is the absence of well-established sets of equations governing the behavior of marine ecosystems, which play a key role in ocean carbon dynamics.
Consequently, fundamental processes, such as the formation and sinking of organic matter from the surface into the ocean interior are crudely parameterised.
Improving the representation of these processes in global ocean biogeochemical models, embedded within Earth System Models (ESMs) used to project future
climate change, is thus an important goal of current research and of this project in particular. Specifically, we seek to evaluate and improve the performance of
MEDUSA (Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification), the ocean biogeochemical model in the next generation Met Office/
NERC Earth system model (UKESM), currently under development. MEDUSA models the interaction between macro- and micro-nutrients, phytoplankton and carbon,
representing these processes via a range of parameterisations and associated parameters, which can have significant impact on key processes controlling marine
uptake of atmospheric CO2. We seek to "tune" these parameters to better fit observations.
To achieve this a number of challenges need to be addressed. First, because of the complex interaction between biogeochemistry and circulation, model sensitivities
vary both globally as well as regionally, and also with respect to the model field (e.g., nutrients v primary production). Second, evaluating the performance of global
models is prohibitively expensive as every parameter change requires integrating the model for several thousand simulated years to equilibrium before the model can
be compared with observations. As a result there have been very few attempts at systematically optimising the performance of models such as MEDUSA. To overcome
this, the student will exploit a fast "offline" tracer simulation scheme and recently-developed mathematical optimisation techniques to optimise MEDUSA, a first for a
global biogeochemical model of this complexity, especially one used in a state-of-the-art ESM.
Key outcomes of this project include (1) an estimate of MEDUSA's sensitivity to various parameters and thus the relative importance of key processes that affect the
strength of the biological carbon pump; (2) an optimal set of parameters that minimizes the model-observation cost function built on several fields; and (3) a quantitative
assessment of the impact of parameter optimisation on projections of Earth system change such as climate sensitivity made by UKESM1.
This project brings together ocean biogeochemists, a mathematician and an Earth system modeller and the student will benefit from working actively with scientists from
several disciplines, including the UKESM model development core group. S/he will receive training in not only marine biogeochemical and Earth system modelling, but
also in high performance computing, numerical analysis and mathematical optimisation techniques with broad applicability in science and engineering. The student will
be affiliated with Oxford's NERC-funded Environmental Science Doctoral Training Partnership (DTP) in Environmental Research and will thus benefit from courses offered
through the DTP as well as the Mathematical Institute.
Eligibility: UK/EU students with a good (2.1 or higher, or its equivalent) first degree in the natural sciences, maths or engineering and strong computing skills are
encouraged to apply.
Application process: To apply follow the instructions at http://www.earth.ox.ac.uk/graduate_admissions. Informal inquiries may be directed to: Samar Khatiwala
