PhD, Masters or Honours Topics: Coral Reef Dynamics Integrating Geospatial/Earth Observation/Ecology
General
If you are interested in working as part of a collaborative, supportive, multi-disciplinary team that links different disciplines across academia, governments, industry and NGOs, on the topics below please contact c.roelfsema@uq.edu.au to it further.
Collaboration/Supervision possible with: Chris Roelfsema, Dylan Cowley, Nikki Brown, Stuart Phinn UQ, Julie Vercelloni QUT/AIMS, Emma Kennedy, Juan Carlos Ortiz AIMS and relevant others
Coral Reef research can focus on work on the Heron Reef but are not limited to that.
Funding
These project do not have funding or scholarships currently, but are supported by extensive pre-existing data archives of fully corrected satellite image archives and field data sets, a collective group of researchers working on the site, and ability to be supported in scholarship and funding applications.
Background
Since 2002 UQ Team have used Heron Reef as basis to develop integrated earth observation and field data monitoring, modelling and mapping approaches. Part of that work was establishing a detailed field-based baseline of the reef, which is completed annually and has produced a 20+ year annual data set. Since 2011, the Reef Check Australia Coral Watch Field teams have joined the surveys and collected their associated data sets. Iin 2023 we collected orthomosaics of 20-50 m for 10 sites around Heron Reef, this provide the possiblity to get more detail benthic information and higher spatial scale locally.
PhD Topics
The data sets themselves provide a wealth of information for interested students to work on, hence we aim to engage with those interested in building coral reef science and management related , knowledge, skills, network, experience and development opportunities to enhance existing, or develop new careers.
If you are interested, please contact c.roelfsema@uq.edu.au to discuss how to develop a research project for special topic, masters or PhD research that might suit you focussing on:
- Ecological assessment of the benthic field data reviewing not only coral cover but also coral morphologies, or algae cover or other
- Developing approaches in GEE for time series analysis to link field data to image date to get high resolution thematic maps of Heron reef.
- Ecological assessment over time of benthic components, but also impacts, fish, inverts and general coral healthy using coral health chart, reef check data and geolocated photos
- Any other topic that promotes the use of the existing field data and/or high resolution image data.
- Or any other related topic.
