Potential PhD projects and scholarships

Potential PhD topics:

 1. What ocean do Lagrangian observing platforms (e.g., Argo and drifting buoys) observe ?

In the mid- and high-latitudes the ocean circulation is composed largely of eddies and fronts. In isolation an ocean eddy is relatively stable being in quasi-geostrophic balance and retaining a closed material surface around its core water mass. It is only through the disruption or destruction of this balance through eddy- interactions that an exchange in mass with its environment takes place. Only at these times is it possible for a Lagrangian observing platform to enter or exit the eddy circulation. This poses many interesting questions such as how frequently do these platforms observe eddies and what are the implications for constructing climatologies of the ocean and ocean forecasting. This research would make use of state of the art high resolution ocean models, analysis of altimetry and the in situ Argo and drifting buoy observations available at the Bureau of Meteorology and the global ocean observing system.

2. Characterisation of ocean forecast errors from an ocean forecasting system . A state-of-the-art prediction system makes several assumptions about the errors of the observing system, the ocean models, the atmospheric forcing and data assimilation methodology. Correctly modelling and estimating these errors and validating or improving these assumptions is critical to further improving performance. This project will focus on the available database of forecast innovations and increments from the BLUElink ocean prediction system and determine the systematic bias as well as the statistical distribution. Specific methods will then be developed to deconstruct and attribute error to different components of the system as well as hypothesis testing.

3.  Helen Beggs leads the  GHRSST Tropical Warm Pool Diurnal Variability (TWP+) Project  which aims to quantify diurnal warming of the surface ocean over the Tropical Warm Pool to the north of Australia and to validate and compare various diurnal variation models over this region.

The  International Group for High Resolution Sea Surface Temperature (GHRSST) TWP+ data set  would be a great resource for any PhD student with a background in either physical oceanography, air-sea heat exchange, marine meteorology and/or satellite oceanography. Further information on the TWP+ Project can be found at  https://www.ghrsst.org/ghrsst-science/science-team-groups/dv-wg/twp/  < https://www.ghrsst.org/ghrsst-science/science-team-groups/dv-wg/twp/>  .

The  GHRSST Workshop on Tropical Warm Pool and High Latitude SST Issues  (Melbourne, 5-9 March 2012) would be an excellent opportunity for a new PhD student to choose a TWP+ related research project that matches their interests and abilities. The workshop will focus on presentations relating to initial research for the TWP+ Project and using the TWP+ data set during the three working days of the GHRSST workshop. Further information on the GHRSST Workshop can be found at  https://www.ghrsst.org/ghrsst-science/Meetings-and-workshops/workshop-on...  < https://www.ghrsst.org/ghrsst-science/Meetings-and-workshops/workshop-on...  including a draft agenda which lists the current TWP+ research activities.

4. Impact of East Australian Current observations Tasman Sea eddies in an ocean model

Introduction

Can observations of the East Australian Current using a HF ocean surface radar improve model forecast skill of meso-scale eddies in the Tasman Sea?

The study will use observations at Coffs Harbour (30S, 153E) which extend approximately 100 km east across the East Australian Current (EAC) and perform assimilation impact studies on a domain encompassing upstream of Coffs Harbour, the EAC separation (at approximately Smoky Cape, 31 S), and the Tasman front (across to New Zealand), with a particular emphasis on meso-scale eddies.

OSR observations

The HF OSR measures surface currents in the top few tens of centimetres of the ocean, on a few km resolution with a range of around 100km over 10 minute time scales. The OSR is part of the IMOS ACORN facility and is planned to commence operation in February 2012. Routine data delivery could be expected by mid 2012. Observations show the EAC is largely barotropic, so OSR should be representative of the depth-integrated current.

The Ocean Model CLAM? Assimiliation

The HF OSR provides currents in regions where the two radars overlap (and the subtended angles of the ray are greater than ~20 Outside of this region there is another equally extensive area where there is only one useful current vector component resolved. While not suited to visual interpretation, single current vector components can be assimilated into ocean models.

The model already assimilates altimetry, SST and temperature and salinity profiles, so any skill improvement will be in excess of this. The assimilation of HF OSR observations may also be useful in the situation where altimetry is degraded (due to loss of satellites or other problems). It would be useful to quantify the impact of assimilating OSR currents in the absence (or reduction) of altimetry.

Possible candidate data-sets for skill evaluation are feature tracking, surface drifters (these are probably drogue to a few metres depth), or synTS. The first two sources will probably generate sparse data-sets. Maybe the evaluation will be achieved by looking at the increments in SSH?

Links to other Work

We have previously looked at the impact of observations on models using the error estimates in the data assimilation system (Oke  et al. , 2009). It would be instructive to see how data withholding experiments compare to the observation network design study tool.

5. Predictive mapping of seabed cover, benthic habitats, benthic biodiversity using multibeam bathymetry and backscatter data

Coastal marine benthic environment, which is dreadfully under-studied, has significant economic and conservation values. Sustainable management of this marine ecosystem requires high quality physical and biological datasets on the benthic environment and scientific evidence on the interactions between these physical and the biological variables. Modern mutlibeam sonar systems, with different sonar frequencies, are capable of accurately mapping large area of seabed from water depth of a few metres to thousands metres. They can provide high-resolution and near-complete coverage of bathymetry and acoustic backscatter data for mapping seabed substrata, benthic habitats and benthic biota.

The proposed project would involve intensive field campaigns collecting multibeam data, water column data, sediment samples and biological data. The collaboration with OUC is critical for the collection and analysis of these data. We would provide expertise in the areas of data analysis, modelling and result interpretation.

6. Generalised dependence for the ocean sea drag

The sea--‐drag coefficient is the main property which is employed to parameterise the air--‐sea interactions in large--‐scale models, from engineering applications to climate research. Over the last 30 years, however, scatter of the experimental dependences for the sea drag parameterised as a function of wind speed and/or wave age did not improve. The proposed project would intend to develop a generalised parameterisation of the sea drag as a function of multiple environmental forcings, for use in meteorological, climate and ocean engineering applications.

7. Coastally trapped wave observations and modelling around Australia

Program Code: 1082

Supervisors:  Prof. Xiao Hua Wang ( [email protected] ), Dr Ming Feng, CSIRO, A/Prof Moninya Roughan and Dr Andrew Kiss (UNSW)

Australia is surrounded by major ocean boundary currents – with the East Australian Current off the east coast, the Leeuwin Current off the west coast, and the South Australian Current/Flinders Current off the south coast. The Integrated Marine Observing System (IMOS) has set up shelf circulation monitoring systems for the major boundary current systems over the past six years. The observing systems include shelf moorings, gliders, and surface radar systems. The ocean boundary current systems vary on different time scales, such as seasonal and intra-seasonal. The aim of this study is to utilise the IMOS mooring networks and numerical models to understand the coastally trapped wave propagations around Australia, forced by wind anomalies on intra-seasonal and whether time scales, and their interactions with the ocean boundary current systems. The intra-seasonal variability of the ocean boundary currents are important in understanding the extreme events in these systems.

8. Remote sensing study on the East Australian Current

Supervisors:  Prof. Xiao Hua Wang ( [email protected] ) and Dr Zhi Huang, Geoscience Australia

East Australian Current (EAC) is a significant boundary current that flows poleward. On the way, it separates and generates many large and small eddies that cause lots of oceanographic dynamic. It has significant ecological impact on the eastern margin of Australia from about 25S. This PhD project aims to use time-series remotely sensed data to map EAC’s spatial structures and investigate the spatial and temporal variability of EAC’s characteristics. The remotely sensed data to be used include more than 10 years MODIS SST and Chlorophyll a datasets. We also intend to use satellite altimetry data in combination with the broad scale BlueLink model to help the mapping and validation, especially in the identification of eddies. This PhD project will further develop the techniques used in supervisor’s (Huang) similar study on the Leeuwin Current of Western Australian margin (Huang and Feng, 2015). Co-supervisor Wang’s expertise in EAC system will be utilised in guiding the design of this study and assessing the results of this study, among others. The successful PhD candidate is expected to have a strong research and analytical skills. Experience and skills in either Remote Sensing or Physical Oceanography field or both are highly desirable.

9.  Mapping and modelling the coastal upwelling along NSW

Supervisors:  Dr Zhi Huang and Prof. Xiao Hua Wang ( [email protected] ), Geoscience Australia

Coastal upwelling is important for marine ecosystems and the economy, because of its elevated primary and secondary productivity and large potential for fish catch. Upwelling along the New South Wales (NSW) coastal areas forms a prominent upwelling system. The upwelling system occurs more or less continuously from austral spring to autumn. It is believed that the East Australian Current (EAC) plays a critical role in this upwelling system.

The ability to investigate the development of individual upwelling events became available in recent years since the production of highly frequent remotely sensed SST data. The Himawari-8 (H-8) is a new generation geostationary satellite carrying an Advanced Himawari Imager (AHI), capable of providing geophysical data at a spatial resolution of 2km and a temporal resolution of 10-mins full-disk frequency. This PhD project contains two main stages. Firstly, this project uses the H-8 SST data to identify and explicitly map the development of individual upwelling events along the NSW coast. The project then uses numerical ocean model(s) to simulate the development of these events to investigate the major underlying mechanisms. The results of this PhD research would significantly advance our knowledge on the NSW coastal upwelling system which is likely to be increasingly influenced by the climate change.

These brief research questions are possible projects for research higher degree students under the supervision of A/Prof.   Stuart Pearson .

Climate change implications for Estuaries

Climate variation and change will impact estuaries in a manner and to a degree that is presently poorly understood due to the uncertainties regarding future forcing and theoretical impediments to our quantitative understanding of estuarine processes at management timescales. Estuarine habitats, water quality, shoreline stability, long-term sedimentation, groundwater, freshwater management as well as the inundation of adjacent land and built environment will all potentially be significantly impacted by climate change.

The purpose of this project is to determine likely changes in forcing processes and extreme events (floods, droughts, heat waves, coastal storms) on Australian estuarine ecosystems and their future management.

Specific questions that will be addressed are as follows:

How are estuarine ecosystems anticipated to change with climate?

What options can be exercised to address these changes within estuaries and their catchments?

What appropriate strategies can be exercised to minimise ecological, social and financial risk in estuarine systems?

This project would be supervised in collaboration with suitably qualified ecologists.

Geomorphological behaviour of estuaries under climate change

Estuarine geomorphological behaviour and its response to physical modification and bioturbation provides the physical backdrop for estuary change. A contemporary need is to integrate science and engineering approaches to understand estuaries on a range of nested time scales: the storm event cycle; interannual climate variability; multi-decadal climate variability; centennial to millennial sedimentological and geomorphological processes.

Specifically, marine and terrestrial sedimentation determines the rate of estuarine infilling and changes in estuarine form according to its maturity (Roy  et al ., 2001, Structure and Function of South-east Australian Estuaries,  Estuarine, Coastal and Shelf Science ,  53 ). Floods play a major role in infilling, flood plain sedimentation as well as scouring during major events.

Following a review of the role of time scale in estuary development, detailed assessment of selected sites would be undertaken as case studies.

HDR coursework 

HDR coursework is mandatory for some of our research degrees. HDR coursework adds to your researcher toolkit so you can graduate with a robust set of skills, for a career in academia or industry.

Your faculty may elect to define certain units of study as mandatory for a given degree, or define any other studies as required by the progress evaluation panel of the research project. Refer to the relevant course in the  handbook .  

Frequently asked questions

Getting started, do i need prior research experience.

Yes, all HDR courses require prior research experience. This is because HDR courses are largely self-driven, requiring pre-requisite research, time and project management skills.

If I have no prior research experience how can I get started?

If you do not have any previous research experience, there are ways to gain what you need. Both the one-year honours and masters by coursework degrees containing substantial research components are great pathways into research. These courses will allow you to gain the research skills necessary to apply for the PhD.

What is the difference between a Master of Philosophy/Research and a PhD?

The PhD is our premier research award and the highest qualification on the Australian Qualifications Framework. The PhD is usually three years full-time or six years part-time.

The Master of Philosophy/Research is usually one to two years full-time or four years part-time (part-time is available to domestic students only). A PhD thesis is generally around 80,000 words while a master’s thesis is 50,000 words.

How do I find a supervisor?

To browse through the profiles of our researchers and learn about their current and past research, please refer to Find a Researcher . Here, you will also be able to access the publications lists and contact details of our researchers. 

My research idea crosses two disciplines – is this a problem?

No. Interdisciplinary research is highly regarded in the world of academia and working across disciplines can be very beneficial in developing and demonstrating different analytical skills. Working on research from two perspectives can also offer insight that you would not be able to achieve from one discipline perspective.

What are the English language requirements for a PhD?

Please check your  course page  for the requirements of each course. Generally, the English requirements are between 6.0 to 7.0 IELTS overall or equivalent in other accepted English proficiency tests.

How much do HDR courses cost?

There are no course fees for domestic students – fees are covered by the government Research Training Program (RTP) fee offset. However, fees apply to international students. Please refer to the  course page  for fee details.

What scholarships are available?

We have one of the largest research schemes in Australia. Opportunities include the Australian government-funded Research Training Program (RTP) stipend scholarships, and the University of Sydney and faculty-specific awards. Explore your options .

Degree progression

Do i have to undertake hdr coursework.

It depends on your degree. Your faculty may define certain units of study as mandatory for a given degree. Where this is not the case, you may still have the opportunity to complete units of study that you find useful to support your learning and research. 

Can I transfer from the Master of Philosophy into a PhD?

It is possible for students to move to the PhD after the first year of study, if you have made satisfactory progress and if the transfer is approved by your Faculty. It is important to inform your supervisor of your plans early so that you can work on a timeline together to achieve this goal.

Support during your studies

Am i able to work while studying my hdr course full-time.

Yes, you can work during your PhD. How many hours you take on is at your own discretion, and you must ensure that you still allow time for the completion of your research. International HDR students can generally work more hours than coursework students. Please check your individual visa for specific restrictions.

Will the university employ me during my PhD?

There are sometimes opportunities for PhD candidates to engage in paid employment at the University, but this is not guaranteed and is dependent on the Faculty/Department. If opportunities do arise, they may be in the form of teaching, marking, acting as a research assistant, or other roles.
