A validation of coral geochemical records to reconstruct suspended sediment loads to the Great Barrier Reef lagoon (Old ID 22242)
Stephen Lewis
01 Jul 2015 - 01 Mar 2016
While coral geochemistry records are widely cited as evidence for increased suspended sediment loads delivered to the Great Barrier Reef since the 1850s, there has been little replication or quantification of the records. Indeed, most records are based on cores collected prior to the year 2000 when limited catchment monitoring data existed to 'validate' the interpretations that certain trace element ratios provided proxies of annual sediment loadings. This project will analyse the geochemistry of coral cores collected in 2012 from sites in the central GBR and compare the ratios to measured sediment and particulate nutrient loads from the Burdekin River.
Nest to Ocean - Gunggandji-Mandingalbay Yidinji Rangers
Caitlin Smith
01 Jan 2026 - 30 Jun 2026
The Nest to Ocean funding scheme supports community-based sea turtle nesting monitoring across Queensland. Gunggandji-Mandingalbay Yidinji Peoples Prescribed Body Corporate has successfully secured funding through the Nest to Ocean program to monitor sea turtle nesting across GMY Sea Country. TropWATER, JCU will support the GMY Rangers by providing expert advice, assisting with drone survey design and implementation, and supplying vessel and skipper support. TropWATER will also assist with data analysis and report preparation.
The role of seagrass dispersal by marine mega-herbivores, dugong (Dugong dugon) and green sea turtles (Chelonia mydas). (Old ID 22411)
Samantha Tol
02 Mar 2014 - 02 Mar 2017
This project will investigate the dispersal mechanisms of tropical seagrasses and determine which mechanisms are most effective for long distance dispersal. It will examine whether marine mega-herbivores (dugongs and green sea turtles) disperse seagrass seeds through their fecal matter and whether those seeds are viable. It will determine how long seagrass fragments, created by abiotic and biotic mechanisms, remain viable and establish new meadows. This information will be used to model which seagrass meadows are at greater risk of slow recovery after a large scale loss. This recovery model will have the potential to highlight which seagrass meadows rely solely on dispersal by marine mega-herbivores for recovery.

Seagrass Monitoring and Research Ports North
Michael Rasheed
12 Sep 2025 - 31 Dec 2030
Ports North in partnership with James Cook University’s TropWATER Seagrass Ecology Group have been engaged in seagrass monitoring and research programs in the Ports of Cairns, Mourilyan, Karumba and Thursday Island since at least 2001. The monitoring programs involve annual surveys that are conducted between October and December each year (Thursday Island is conducted in February/March). underpinning major research initatives and our understanding of tropical seagrass ecology. The monitoring programs: • Provide a regular update of the marine environmental health of the ports • Satisfy commitments linked to maintenance dredging and sea disposal approvals • Provide an assessment of seagrass condition and resilience to inform port management. In addition to monitoring, the program is utilised and leveraged for broader initiatives and contributions for joint research and activities including providing: • A key information feed and contribution to regional report cards including Wet Tropics Partnership for Healthy Waterways and for Torres Strait Reporting • A link to Traditional Owner participation in environmental monitoring and research • A range of value-added seagrass research projects including leveraged funding from Australian Government and industry funded research programs investigating seagrass recovery and restoration
Southeast Asian Peatlands as a Natural Climate Solution
Sigit Deni Sasmito
23 Jun 2026 - 23 Dec 2026
The Programme aims to support research and strategic analysis on Peatlands in Southeast Asia in order to strengthen the evidence base for philanthropic engagement in peatland conservation and restoration for climate resilience outcomes across the region. The Programme is intended to generate actionable recommendations and investment pathways for philanthropy and other stakeholders to advance climate adaptation and mitigation, biodiversity conservation, ecosystem resilience, and sustainable livelihoods in Southeast Asia.
Exploring Nature Based Economies with the Lama Lama Rangers
Caitlin Smith
01 Aug 2026 - 01 Dec 2027
This project aims to upskill the Lama Lama Rangers to conduct seagrass monitoring using boat based and drone methods. Using the knowledge from these surveys we aim to explore nature based economy and blue carbon opportunities on Lama Lama Sea Country.
NESP 3.5: Supporting regional planning in northern Australia: Building knowledge, skills & partnerships for understanding seagrass distribution (Old ID 29021)
Alexandra Carter
01 Feb 2023 - 20 Nov 2026
Northern Australia has vast development opportunities but limited knowledge of the environment to inform decision making. This region has globally significant seagrass habitat, supporting dugong, green turtle, and commercially important fish and prawns. However, knowledge about seagrass habitats for extensive areas of the coast is limited - data is patchy or not freely available, few large-scale mapping surveys have been conducted, and even fewer seagrass long-term monitoring programs exist. This project will address these problems by: 1. Mapping selected benthic habitats, with a focus on seagrass, using methods consistent with previous and ongoing surveys in northern Australia. 2. Establishing a benchmark of seagrass habitats for Traditional Owners, Indigenous communities, rangers, management agencies, ports, industry, and researchers to assess change. 3. Partnering with management agencies and ranger groups to co-design mapping and monitoring methods in remote areas that use new technology such as drones. 4. Compiling and synthesizing historical seagrass data into a publicly available spatial database to create a permanent record. 5. Interpreting and reporting on survey findings, including providing advice on options for establishing monitoring programs.

Blue carbon under heatwave: how vegetation governs greenhouse gas exchange in coastal wetlands under extreme heat
Sigit Deni Sasmito
01 Sep 2026 - 30 Jun 2027
Coastal wetlands store globally significant 'blue carbon', yet their response to intensifying heatwaves is poorly understood. The work develops a mechanistic understanding of how warming reshapes coastal wetland carbon function, informing blue carbon accounting, conservation, and Australia's climate commitments.
