Aquaculture effluent treatment with bioreactors
This project is the first in Australia and the tropics to assess the ability of ‘denitrification bioreactors’ (woodchip-filled trenches) to remove nutrients from effluent leaving an aquaculture farm. It is being carried out on a barramundi farm in the Great Barrier Reef catchment in North Queensland. Funded by Mainstream Aquaculture and the Australian Govt. 2020-2022. Contact Alex Cheesman Sequestering carbon through enhanced weathering
Arresting the build-up of atmospheric CO2 is one of humanity’s biggest challenges. As part of a global effort, we are testing the idea that the removal of carbon dioxide from the atmosphere through weathering of rocks can be accelerated by applying crushed basalt to sugarcane fields.

Isotope-enabled modelling of catchment water balance
Catchment water balance modelling can help make more informed water allocation decisions. This project uses stable isotopes of water (rainfall, stream and groundwater) to improve predictions made by catchment water balance models for the Tully and Barron River catchments in North Queensland. Funded by JCU, 2018-2021, in collaboration with the International Atomic Energy Agency (IAEA). Contact Han She Lim or Niels Munksgaard |

Improving urban runoff water quality using smart sensors and IoT
This project brings smart city technology (Internet of Things and smart sensors) into urban water management to improve urban water quality discharging to the Great Barrier Reef. The project is collaboration between Cairns City Council and JCU. Funded by the Dept of Industry, Innovation and Science to Cairns Regional Council, 2018-2020. Contact Wei Xiang or Han She Lim |

Denitrifying bioreactors to improve water quality
Denitrifying bioreactors are an on-farm technology for removing dissolved inorganic nitrogen from agricultural drainage water. They may have a role in reducing nutrients running to the Great Barrier Reef lagoon. This project, in partnership with Jaragun Pty Ltd, will assess their efficacy in the Wet Tropics.

Long-term monitoring of mangrove forests using Landsat
This project will examine changes in mangrove forests in the Darwin area over 30 years. We will develop an algorithm to process images from the Landsat archive, and then quantify trends in phenological and spatial variations over time. Funded by a JCU Postraduate Fellowship, the Wet Tropics World Heritage Authority (Student Grant) and NIESGI Cia. Ltda, 2016-2020. Contact Nicolás Younes Cárdenas Soil management to reduce Panama disease in bananas
Panama disease (Fusarium Wilt) poses a major threat to the Australian banana industry. We are finding out what soil properties suppress the disease and how suppressiveness might be enhanced. See more here. And here (2021 Science and Innovation Award) Funded by Hort Innovation (BA14014 2.6), 2016-2020. Contact Paul Nelson. |

What is natural? Humans, megafauna and climate in Nth Australia
Did human arrival in Australia lead to the extinction of the megafauna and lasting change to Australian ecosystems? In this project we are separating human activity from global climate change effects in shaping the modern environment of northern Australia. Funded by the Australian Research Council (FL140100044), 2015-2019. Contact Michael Bird |
Reef island geomorphology - Raine Island
Raine Island is a low-lying coral cay vulnerable to many climate change impacts. It also has great cultural importance, and is the world’s largest nesting site for green turtles. We’re working to understand how the island will change into the future, and what we can do about it.
Funded by the Great Barrier Reef Foundation, 2016-2018. Contact Scott Smithers

Identifying sources of fine sediment to protect the Great Barrier Reef
What type of sediment transported from rivers via floods has the greatest influence on water clarity in the Great Barrier Reef lagoon? The research will identify the key properties and sources of this material using cutting-edge tracing techniques, enabling more effective actions to improve water quality.
Funded by Qld Dept. of Science, Innovation Technology and Innovation. Contact Zoe Bainbridge

Reducing greenhouse gas emissions from mango and banana cultivation
Agricultural soils are a significant source of the greenhouse gases nitrous oxide and carbon dioxide. We are examining how enhanced-efficiency fertilisers and mulching practices might be used to reduce greenhouse gas emissions from banana and mango fields.
Funded by Carbon Farming Initiative (AOTGR2-0076), 2013-2017. Contact Paul Nelson

Mobile Isotope Monitoring for Environmental Studies
We use stable isotopes of carbon, oxygen and hydrogen as tracers of processes in the carbon and water cycles. Portable laser spectrometers enable us to carry out high-frequency, real-time analysis to help identify sources and sinks of carbon in forest and savanna landscapes and to understand tropical rainfall patterns and water use by plants.
Funded by the Australian Research Council (LE110100144, LE130100159). Contact Niels Munksgaard

Water and biogeochemical fluxes in a tropical rainforest
We continuously monitor water and geochemical fluxes in Atika Creek on JCU's Cairns campus. The work helps us understand how water moves through a rainforest system and provides baseline data by which to compare impacts of climate change and human activity on tropical catchments.

Using cave guano to reconstruct past tropical environments
Records of past environments can be found in caves, in the faeces (guano) of bats or birds roosting there. We are exploiting these records to reconstruct palaeoenvironments, especially the extent of savannas and rainforest refugia, over the Last Glacial Period in island southeast Asia.
Funded by National Geographic Society and Australian Research Council (DP140101319), 2010-2016. Contact Chris Wurster
