Overview
Background
Research interest: Monitoring ecosystem health of coral reefs and seagrass habitats, integrating field and remote sensing image datasets, and the developing applied cost-effective mapping and monitoring approaches. Developed approaches have been adopted as standard practice globally, making a difference in conservation of these valuable habitats. The long term monitoring studies at Heron and Moreton Bay formed the basis for the development of mapping and monitoring over time and space at local to global scale.
Current projects:
1) Long term monitoring of benthic composition at Heron Reef (2002-ongoing). Annual photoquadrate surveys are being collected at Heron Reef, Southern Great Barrier Reef. Initiated to develop remote sensing mapping approaches and assess coral composition over time. The resulting Maps, photo quadrate and benthic data, spectral reflectance are accessible online.
2) Long term monitoring of seagrass composition and abundance in Moreton bay Marine Park (2000-ongoing). For Eastern Banks it included monitoring seagrass species, cover and biomass 15x times since 2004 using photoquadrate survey and satelite imagery and for Moreton Bay it included seagrass extent and cover (2004, 2009, 2015, 2021, 2022), all data accessible via Moreton Bay Research Station.
3) Smart Sat CRC Hyperspectral Remote Sensing of Seagrass and Coral Reefs 2023-2027. Collaborative effort with CSIRO, Adelaide University, DES Adelaide Coastal Waters.
4) 3D GBR Habitat Mapping Project 2015 - ongoing: Mapping and monitoring geomorphic zonation, bottom type and predicted coral type habitat for every Great Barrier Reef within the Marine Park.
5) Global habitat mapping project 2019-2023 Developed and implemention of global habitat mapping as part of the Allen Coral Atlas resulting in extent, geomorphic and benthic maps for reefs globally, funded through with Vulcan Philanthropies in partnership with; Planet; the Arizona State University and the National Geographic Society.
Other projects: Advisor for Reef Cloud Australian Institute of Marine Science and Coordinated Global Research Assessment of Seagrass System (C-GRASS).
Current position: Associate Professior in Marine Remote Sensing. Academic Director Heron Island Research Station and affiliated researchers with Centre for Marine Science and Centre for Biodiversity and Conservation Science
Capacity building: under/post graduate courses; Msc/PhD supervision, workshops/courses; Remote Sensing Educational Toolkit, and online courses (e.g. TNC)
Citizen science: Strong supporter of citizen science based projects, as trainer, organiser and advisor for Reef Check Australia, CoralWatch, Great Reef Census and UniDive.

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.

Background
Since 2000 the UQ Team have used Moreton Bay 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 seagrass in the Moreton Bay and specificly Eastern Banks. In the last 20+ years seagrass has been mapped regulary in this region.
