If such an attractive source existed, how would its potential users find it? Download report ( PDF file 829KB).

Metal bioaccumulation through food web pathways in Port Curtis. Technical Report 31.
Port Curtis is an international trades port supporting major local industries as well as a large commercial and recreational fishing industry. Previous studies in the harbour (CRC Coastal Zone, 2005), have determined that despite relatively low metal concentrations in the water column there appears to be some accumulations of some metals in the marine organisms that inhabit the harbour. Aquatic animals can absorb metals through exposure in sediments and the water column but also via their diet, through metals accumulated in their food source. This route of exposure was investigated in this study. Download report. ( PDF file 1.27MB)

Nutrient dynamics and pelagic primary production in coastal creeks delivering into Keppel Bay. Technical Report 32.
This report describes the investigations into the coastal creek system conducted within the Fitzroy agricultural contaminants project. Before this work started there had been only a limited data acquisition on the water quality parameters in several of the coastal creeks carried out by the Queensland Environmental Protection Agency (EPA). These data are a valuable augmentation to the data collected under Coastal CRC auspices. We briefly outline the consolidated dataset, draw qualitative conclusions from it, and develop a conceptual model reflecting the interacting processes. These analyses are then the starting point for the development of a quantitative characterisation of the role of the coastal creeks in the biogeochemistry of Keppel Bay. Download report.

Keppel Bay: physical processes and biogeochemical engineering. Technical Report 34
In recent years there has been concern that catchment-derived nutrients and sediments discharged by rivers into the lagoon of the Great Barrier Reef are having a deleterious impact on near-shore reef ecosystems. On average, the Fitzroy River delivers the second largest quantity of these materials to the lagoon after the Burdekin River. The Fitzroy Agricultural Contaminants Project (AC), which is a Coastal CRC project, included amongst its aims the development of an understanding of the fate and impact of these agricultural contaminants (nutrients and sediments) within the Fitzroy Estuary-Keppel Bay system.

Pesticide, polycyclic aromatic hydrocarbon and metal contamination in the Fitzroy Estuary, Queensland, Australia. Technical Report 37.
The Coastal CRC initiated a monitoring program in 2001 to quantify the concentration and loads of pesticides delivered to the Fitzroy Estuary (FE) from the Fitzroy River catchment. This monitoring has been extended during 2003-06 to include analysis for polycyclic aromatic hydrocarbons (PAHs) and metals in fine sediments and core samples from the FE and Keppel Bay. This work adds to the very limited studies on PAH and metal contaminants particularly in benthic sediments from the Fitzroy Estuary. Download report. ( PDF file 1.31MB)

Numerical hydrodynamic modelling of the Fitzroy Estuary. Technical Report 38.
A numerical hydrodynamic model was developed for the Fitzroy Estuary/Keppel Bay region in order to investigate the circulation, flushing and connectivity of the region. The model also served as the driver for biogeochemical and sediment transport models which were coupled to the hydrodynamic model. The model was forced with measured meteorological fields at the sea surface (wind, pressure and temperature), river discharge at the barrage and sea surface elevation, temperature and salinity at the offshore boundary. The offshore boundary forcing was obtained using a nesting strategy involving a larger-scale regional model. Download report. ( PDF file 8.05MB)

Modelling of fine-sediment transport in the Fitzroy Estuary and Keppel Bay. . Technical Report 39.
To provide a better understanding of the sediment dynamics in the Fitzroy Estuary, a coupled, one-dimensional (1-D), vertically and laterally averaged model of hydrodynamics and sediment transport was developed and applied to the main channel of the estuary during the first phase of the Coastal CRC (Margvelashvili et al., 2003). The work highlighted a strong coupling between the Fitzroy Estuary and Keppel Bay and revealed the complex dynamics of sediments associated with flocculation and an upstream tidal pumping of sediments. However the 1-D model constraints precluded accurate assessment of sediment delivery to the ocean. In phase 2 of the Coastal CRC, these limitations were eliminated by using 3-D fine-resolution hydrodynamic and sediment transport models and extending the modelling domain into Keppel Bay. The modelling objectives were to provide a better understanding of the sediment transport in a coupled estuaryŻbay system and to assess sediment loads to the ocean by developing a calibrated 3-D fineresolution model and running 'what if' scenarios that would assist regional planning. The scenarios involved modelling of the sediment transport under low, moderate, and high river flow regimes with sediment loads from catchments also altered by varying land use practices.

The Fitzroy Contaminants Project - A study of the nutrient and fine-sediment dynamics of the Fitzroy Estuary and Keppel Bay. Technical Report 42
The Fitzroy catchment is the largest Queensland catchment discharging to the Great Barrier Reef (GBR) lagoon. Sediments and nutrients together with anthropogenic pollutants originating upstream in the catchment are discharged from the Fitzroy River via the Fitzroy Estuary (FE) and ultimately into Keppel Bay (KB). The estuary and the bay act as natural chemical reactors where the materials delivered undergo chemical and physical transformations before some are deposited and stored in the growing deltaic and beach areas, with the remainder transported eastward to the southern zone of the GBR lagoon.

Intertidal wetlands of Port Curtis: ecological patterns and processes, and their implications. Technical Report 43
Port Curtis (the Port) is an outstanding natural harbour in and adjacent to the Great Barrier Reef Marine Park. The Port is heavily industrialised around the city of Gladstone along the western shoreline, but elsewhere retains large tracts of natural intertidal wetlands. The overall objective of the Intertidal Wetlands study was to describe ecological patterns and processes and determine the importance of different intertidal wetland habitats in Port Curtis. Considerable effort also went into developing an illustrative conceptual understanding of processes and threats in the area. Download report ( PDF file 1.89MB)

Geomorphology and sediments of the Fitzroy River coastal sedimentary system Ż Summary and overview. Technical Report 47
This report provides an overview of the geomorphic and sedimentary characteristics of the Fitzroy River and Keppel Bay, which comprise one of the largest modern coastal sedimentary systems in Australia. Our results provide new insights into the character and rate of evolution of the Fitzroy River estuary and Keppel Bay, from the Late Pleistocene to historical times. We reveal how riverine and shallow-marine processes that occurred thousands of years ago affect the present day structure of the coast and continental shelf. Importantly, we also identify rates of sediment accumulation for the last several thousand years, and the last hundred years. We compare these empirical data with estimates of the current sediment load of the Fitzroy River to formulate a preliminary sediment budget for the Fitzroy coast. Download report ( PDF file 602KB)

Sediment accumulation and holocene evolution of the Fitzroy River lower floodplain, central Queensland, Australia. Technical Report 48
We examined a suite of sediment cores from across the Fitzroy River floodplain, below Rockhampton, to determine the evolution of the estuary and the record of sediment accumulation over the last 8000 years. Three different depositional environments were targeted during this study; the floodplain, the tidal creeks and the freshwater lagoons. Download report ( PDF file 2.11MB)

Geomorphology and sediment transport in Keppel Bay, central Queensland, Australia. Technical Report 49
Keppel Bay is a macrotidal environment that represents the interface of the large catchment of the Fitzroy River with the southern GBR continental shelf. In this study, we assessed the distribution of sediments and their depositional characteristics using a combination of sediment sampling, and acoustic (sonar) seabed mapping tools. Using statistical techniques, we classified the seabed sediments of Keppel Bay into five distinct classes, based on sediment grainsize, chemical composition, and modelled seabed hear stress (the influence of waves and tidal currents).

A 1500 year record of coastal sediment accumulation preserved in beach deposits at Keppel Bay, Queensland, Australia. Technical Report 51
In this study of the beach-ridge plain at Keppel Bay, on the central coast of Queensland, we examine ridge morphology, sediment texture and geochemistry. We build a detailed chronology for the ridge succession using the optically stimulated luminescence (OSL) dating method. Although our interpretations are preliminary, our results suggest that significant changes have occurred in the rate of shoreline accumulation of sediment, catchment sediment source areas, and that there have been minor falls in relative sea level.

The evolution of jumpinpin inlet. Technical Report 62
This coastal engineering investigation shows that shoreline changes at Jumpinpin are cyclical, resulting from natural coastal processes and not engineered changes at the seaway some fifteen kilometres updrift. A review of existing information and analysis of aerial photographs over a 100 year period has revealed two dominant coastal processes. In the period 1898 to 1936 the inlet was influenced by the process of inlet migration and spit breaching. Two cycles were completed. After 1936 Jumpinpin began to behave in a unique and unexpected manner whereby the inlet comprised two channels in dynamic equilibrium. The northern channel is relatively stable and remains open while a second smaller channel is periodically breached approximately two kilometres updrift. This southern channel breaches as a response to storm and flood activity and is sealed by littoral drift within non-flood years. The presence of the southern channel plus composition of the downdrift bank (Kalinga Banks) has retarded migration of the northern channel and prevented its closure.

Improving our knowledge of Australia's near-pristine estuaries. Technical Report 64
The central aim of the Comparative Geomorphology of Estuaries Project of the Coastal CRC was to improve our understanding of Australia's near-pristine estuaries. As the title implies, the project had a geomorphic focus in that a major output was mapping of geomorphic habitats of a representative selection of nearpristine estuaries from around Australia.

Major achievements of the comparative geomorphology of estuaries project. Technical Report 65
Australia's near-pristine estuaries are some of our most valuable natural assets, with many natural and cultural heritage values. They are important as undisturbed habitat for native plants and animals, for biodiversity conservation, as Indigenous lands and for tourism. They also support near-shore fisheries. In addition, by studying near-pristine estuaries, scientists can learn more about the way humans have changed natural systems. This information then feeds into natural resource management because it constitutes benchmark or baseline information against which similar information from more modified estuaries can be compared.

An initial assessment of estuarine geomorphic habitats as indicators of coastal waterway health. Technical Report 66
An important aim of the comparative geomorphology of estuaries project was to increase understanding of the environmental characteristics of near-pristine estuaries and provide a reference dataset for quantifying changes in habitat patterns in modified systems. It was anticipated that this aim would be fulfilled by identifying key geomorphic characteristics of the near-pristine systems that may be used to benchmark the current condition of, and quantify change within, 'modified' waterways. Here we provide examples of some very promising results obtained from our preliminary analyses of the geomorphic habitat area information contained within the GIS maps available on OzEstuaries.

Antioxidant enzymes as biomarkers of environmental stress in oysters in Port Curtis. Technical Report 70
The estuarine embayment of Port Curtis is Queensland's largest multi-cargo port and the fifth largest port in Australia. It supports major industries in the Gladstone area including the world.s largest alumina refinery and Australia.s largest aluminium smelter. Because the estuary is one of the Coastal CRC.s three key study areas, research by the CRC contaminants team focused firstly on identifying contaminants of concern in a screening-level risk assessment. Although enrichment of some metals in marine organisms was recorded, subsequent projects focused on assessment of organism health to determine if environmental harm had occurred. There was a need to demonstrate a relationship between exposure to a contaminant and an adverse ecological effect. Download report ( PDF file 971KB)

Nutrient dynamics and sediment budgets in the Fitzroy estuary during a flood event. Tecnical Report 72
Changes in nutrient and sediment concentrations along the Fitzroy estuary were investigated during the passage of a flood event in February 2005. The flood event was relatively small and was the last member of a group of three minor floods ending a protracted dry period. The flood came mainly from the Connor catchment with a smaller component from the Comet. The total event volume was equal to the estuary volume, but due to the vigorous tidal mixing in the lower estuary, only the upper part of the estuary remained filled with fresh water for the duration of the investigations.

Contaminant pathways in Port Curtis. Technical Report 73
The Port Curtis Estuary has a well-developed and expanding industry within its catchment. It is also one of Australia's leading ports and is located adjacent to the World Heritage-listed Great Barrier Reef Marine Park. As a consequence of increasing population and industrial activities, the Port Curtis Estuary is expected to receive increasing quantities of contaminant inputs from diffuse sources (e.g. urban runoff) and point source discharges (e.g. industrial effluents). The Contaminant Pathways study has produced the first accurate data on dissolved trace metal concentrations in the coastal waters of Central Queensland and in close proximity to the Great Barrier Reef.

Chlorophyll and suspended sediment assessment in a macrotidal tropical estuary adjacent to the Great Barrier Reef: spatial and temporal assessment using remote sensing. Technical Report 74
This report presents the results of the Coastal CRC remote sensing project in the Fitzroy River estuary and Keppel Bay carried out in 2004-2006, focussing on daily satellite images (collected by the moderate resolution imaging spectrometer, MODIS). Two years (2003-2004) of daily MODIS satellite data were processed to determine total suspended matter, chlorophyll and dissolved organic matter using unique regional algorithms. These satellite-based map products were then compared with the Fitzroy Estuary-Keppel Bay biogeochemical model outputs of total suspended matter and chlorophyll in order to initiate the process of data-assimilation of remote sensing information and modelling work for the Fitzroy estuary. The aim of this data-assimilation work will be to provide the managers of the Fitzroy system with accurate information as well as a predictive capacity for assessing and managing the environmental state of the estuary as an effect of management actions in the catchment and the river.

Decision support for modelling and monitoring assessments of coastal water impacts. Technical Report 75
This report presents information to support environmental impact assessment (EIA) required for development approvals in coastal areas. The report covers the technical aspects of assessments that typically include a combination of computer modelling and field monitoring, rather than the EIA process itself. Experiments in the field or the laboratory are also considered as part of the assessment options. Government regulators involved in an EIA process are the primary audience of the document. The report therefore focusses on supporting the tasks of (i) choosing suitable assessment methods and approaches and (ii) reviewing existing assessments, as these are the stages (as compared to the application stage) where regulators are often involved.

Remote sensing for coastal ecosystem indicators assessment and monitoring. Maps, techniques and error assessment for seagrass benthic habitat in Moreton Bay. Technical Report 76
The purpose of this project was to develop, implement and validate approaches for mapping benthic habitats in Moreton Bay using commercially available remote sensing information and field survey. Due to the focus of monitoring and management programs in the Bay on seagrass properties, notably seagrass density and species composition, the project was confined to mapping this benthic habitat. In the process of deriving maps of seagrass properties, other benthic substrates (e.g. coral and algae) were mapped but not included in the final products. The techniques and data we used were confined to the shallow and clear areas of the Bay, which were also the areas where seagrass was commonly found. Download report ( PDF file 8.81MB)

Enhancing the role of local government in cooperative regional natural resource management. Technical Report 78
The relatively recent establishment of a regional community-based framework for natural resource management (NRM) planning and program delivery throughout Australia provides both challenges and opportunities for achieving sustainable outcomes for NRM at regional and local levels. Local governments potentially have a leadership role in implementing NRM arrangements; however, there are a number of barriers that need to be overcome before this can occur.

The establishment of a regional community-based framework for natural resource management (NRM) planning and program delivery throughout Australia provides both challenges and opportunities for achieving sustainable outcomes for NRM at regional and local levels. These emerging initiatives have the potential to move existing state and local agencies to a higher order of regional community engagement. However, the initiatives will have to evolve within the existing statutory and institutional frameworks for environmental and natural resource planning and management. This suggests a different and evolving role for local government within the new regional arrangements. It also suggests that there are key links between NRM and existing planning processes and practices that must be addressed. Download report ( PDF file 1.38MB)

Securing the foundations: towards improved local government NRM engagement. Technical Report 80
The establishment of a regional community-based framework for natural resource management (NRM) planning and program delivery throughout Australia provides both challenges and opportunities for achieving sustainable outcomes for NRM at regional and local levels. The three case study partners (CSPs) for this research project were some of the first regional natural resource management (NRM) bodies to have their regional NRM plans accredited. Hence, at the commencement of this research project at the beginning of 2005, all three regional bodies had begun the implementation of their respective NRM regional plans. Each of the regional NRM plans had assigned a range of specific NRM responsibilities to local government, both as lead and support agents for this implementation. This report examines the implementation aspects of regional NRM plans, particularly as they apply to local government as a partner in this collaborative process. Download report ( PDF file 390KB)

Enabling adaptive management for regional natural resource management. Technical Report 81
Adaptive management is a concept and process that has been widely promoted for many years as a way for managing complex issues. More recently the Australian Government has promoted adaptive management as part of the programs for achieving regional natural resource management (NRM). It is surprising that, despite its simple logic and wide acceptance as the way forward, the effective application of adaptive management principles and practices in NRM regions proves challenging and elusive. One reason may be the disconnect between the capacity of current political and funding mechanisms and the complex and changing needs of natural and human systems in the wide variety of Australian catchments. Another reason may be limited experience and capacities for achieving coordinated outcomes from the multistakeholder processes required for democratic NRM governance.

Integrated indicator framework for monitoring and reporting on biophysical health and social wellbeing in the coastal zone. Technical Report 82
Indicators are used to monitor and report, in a timely and cost-effective manner, on those aspects of a system that provide the most reliable insight into its overall wellbeing. Using indicators to monitor the effects of resource-use activities on environmental and social health is critical to effective, adaptive and sustainable natural resource management. This report presents an integrated indicator framework and related social indicators developed through research by the Cooperative Research Centre for Coastal Zone, Estuary and Waterway Management (Coastal CRC).

Metal and polycyclic aromatic hydrocarbon contaminants in benthic sediments of Port Curtis. Technical Report 83
In this study, benthic sediments and sediment cores from Port Curtis were analysed for 10 metals and 17 PAHs. The concentrations were compared to the ANZECC (2000) interim sediment quality guidelines. The study confirmed that intertidal (mangrove) sediments tended to collect fine sediments, which contained higher levels of metals and PAHs than did estuarine sediments.

Overview of coastal water habitat mapping research for the Coastal CRC. Technical Report 86
This technical report summarises results of research conducted within the Coastal Water Habitat Mapping (CWHM) project of the Cooperative Research Centre for Coastal Zone, Estuary and Waterway Management. This research aimed to develop acoustic techniques for the discrimination and mapping of seafloor habitats in coastal zones using the acoustic (echo sounder) and groundtruthing (video observations and grab/core samples of sediments) data collected in a number of areas on the coastal shelf around Australia. The study was based primarily on multibeam sonar observation of the seafloor using a Reson Seabat 8125 240-beam echo sounder. Download report ( PDF file 1.95MB)

Designs for remote sampling: review, discussion, examples of sampling methods and layout and scaling issues. Technical Report 87
The variety of methods available for collecting information about the marine environment leads to rich datasets incorporating measurements and observations at a range of spatial and temporal scales. Precisely how to integrate these diverse datasets covering different spatial extents and with varying support has not been satisfactorily addressed in the marine mapping literature. We review remote sampling methods, standard sampling designs and the general statistical assumptions underlying those designs. Download report ( PDF file 768KB)

Organisational change for participatory science research: the Coastal CRC 1999-2006. Technical Report 88
Coastal research has implications for all those involved in coastal decisionmaking. In 1999 the Coastal CRC began its research program espousing ścitizen science∆: the involvement of citizens in the science it was undertaking. But the researchers were drawn from a range of conventional science research organisations. Could the CRC instil the ethos of stakeholder engagement in its research? This study examines stakeholder engagement in the first year of the CRC and again at the research completed in 2006, primarily from the perspective of 36 CRC researchers surveyed.
