WAMSI Node 4.2.1b - Development and validation of an estuarine health index for the Swan Estuary
No full textStatement: The current sampling regime replicates and builds upon those employed during previous studies (1977-2004), and involves the collation and analysis of fish community data collected seasonally over a two year period, from the Swan Estuary, to enable reference conditions to be established and health indices to be calculated. Fish were collected from nearshore and offshore sites (< 2 m and > 2 m deep, respectively) throughout the Swan Estuary. Nearshore sites were sampled using a 21.5 m or 41.5 m long seine net, and offshore sites using composite sunken gill nets, in the middle month of each season between July 2007 and May 2009. All fish were identified to species and the total number of individuals of each species in each sample was recorded. The numbers of each fish species collected in samples from the previous and current studies were standardised by expressing them as count per 21 m net equivalent (seine net data) or as catch rates per unit time (gill net data). The specific method employed to do this was determined following the completion of a net selectivity study. This investigation employed seine nets of each of the sizes used during the previous studies (21.5, 41.5 and 133 m), in order to evaluate biases inherent among the different sampling regimes, and enable the derivation of conversion factors for standardisation of historical and current data. Sampling for this investigation was completed at 20 sites throughout the estuary during October-November 2008 and April-May 2009.Statement: Sampling of the nearshore and offshore fish communities of the Swan Estuary during the study was carried out usually in the middle month of every season between winter 2007 and autumn 2009. The study involved daytime and nighttime sampling (see above).<b>Credit</b><br/>Funding came from Swan River Trust, Department of Water, Department of Fisheries, Murdoch University, WAMSI top-up PhD scholarship - For access to data contact Murdoch University.<b>Credit</b><br/>Fiona Valesini (Supervisor)<b>Credit</b><br/>Steeg Hoeksema (Supervisor)<b>Credit</b><br/>Ian Potter (Supervisor): Centre for Fish and Fisheries ResearchThis project (WAMSI Node 4.2.1b) aimed to develop an index for assessing the health of the Swan Estuary, based on fish assemblage characteristics. <br/><br/>The index incorporates a suite of metrics, each of which measures a different aspect of the fish community, e.g. species diversity and composition, use of the Estuary as a nursery habitat, and the trophic structure (the feeding relationships between species) of the estuarine fish community.The study incorporated and utilized historical data from 1977-2004, plus current sampling (2007-2009), to establish reference conditions for multiple fish community metrics, against which the recent, current and future status of the estuary is assessed.<br/><br/>Data is available as two Excel spreadsheets:<br/>Establishing_reference_and_scoring_seine_Metrics.xls<br/>Establishing_reference_and_scoring_gill_Metrics.xls<br/><br/>The gill net and seine net files contain, respectively, for each offshore and nearshore historical fish sample collected between 1976 and 2009:<br/>(i) the raw values calculated for each of the selected fish metrics comprising the offshore and nearshore health indices;<br/>(ii) the corresponding metric scores (i.e. scored in comparison to the appropriate reference conditions I derived for each metric); and<br/>(iii) the final health index scores for each historical sample.<br/><br/>The historical studies used in the project are all detailed in the final report
Ichthys Gas Field Development - Oceanographic Discharge Modelling Study.
No full textMaintenance and Update Frequency: unknownStatement: Original record compiled for the Western Australian Marine Science Institution (WAMSI), Project 3.8, 2008.<b>Credit</b><br/>Greg Oliver: INPEX Browse LtdThe oceanographic discharge modelling study will provide a quantification of the likely trajectories, fates and consequences of the following production discharges and potential accidental spills that have been identified to date: <br/>- Produced formation water;<br/>- Grey water and sewage;<br/>- Hydrotest water from dewatering of the export pipeline;<br/>- Wastewater from a desalination plant;<br/>- Sediment suspended by dredging/trenching for the subsea pipeline, including potential discharge from directional drilling from land;<br/>- Disposal of the dredge-spoil;<br/>- Sediments suspended by propeller-wash from export tankers<br/>- Sediments suspended during construction activities; and<br/>- Accidental releases of liquid hydrocarbons into the sea.<br/><br/>These studies examine realistic scenarios based on the planned activities and account for trends and variations in ambient conditions. Modelling studies will require the development of fit-for-purpose hydrodynamic models to suit the various studies. Some studies will require modelling that covers a relatively large area and incorporates hourly to decadal time-scales. Others will require modelling at finer spatial and temporal scales. <br/><br/>Objectives:<br/>The objectives of the Oceanographic Discharge Modelling Study are to:<br/>- Predict the hydrodynamic circulation over the wider study area and local Islands using a validated three-dimensional hydrodynamic model;<br/>- Predict the exposure risk from accidental hydrocarbon releases (trajectory, dispersion and weathering of hydrocarbons spills) using a validated dimensional oil spill fates and effects model;<br/>- Predict potential deposition and erosion of sediment in sensitive areas such as beaches and benthic primary producer habitats through coastal transport modelling;<br/>- Predict the fate of sediments released from dredging, dredge spoil disposal and propeller-wash using a validated 3-dimensional spill fates and effects model; and<br/>- Provide model output data to support the assessment of potential impacts arising from accidental hydrocarbon spills associated with the Inpex project. <br/><br/>These include the provision of:<br/>Time-series plots showing the predicted weathering of the specified oil types under local conditions;<br/>Contour plots showing probability of exposure to shorelines and open water locations;<br/>Contour plots showing the minimum elapsed time before exposure by slicks at locations;<br/>Contour plots showing the average and maximum concentration of surface oil at locations;<br/>Probability of exposure to entrained oil at sub-surface locations;<br/>Potential concentrations of entrained oil at sub-surface locations (maximum and average);<br/>Probability of exposure to dissolved aromatic (BTEX and PAH) hydrocarbons;<br/>Potential concentrations of dissolved aromatic hydrocarbons in the water column (maximum and average); and Maximum cumulative doses (concentration x time of exposure) of dissolved and entrained components at sub-surface locations
Genetic subdivision of Roe's abalone, Haliotis roei Grey in south-western Australia
No full textMaintenance and Update Frequency: notPlannedStatement: Samples of H. roei were collected from 10 sites along the south-west and south coasts of Australia, between Kalbarri in Western Australia and West Island in South Australia (see thumbnail). Sites were chosen to include a range of spatial scales. The shortest over-water distance between sites ranged from 13 km (Burns Beach to Waterman's Reserve) to just over 3000 km (Kalbarri to West I.). Samples were obtained between March and May 1997. Repeat samples were taken from two sites, Kalbarri and Canal Rocks, during April 1998. In the repeat samples, animals smaller than those collected in the original sample were targeted. This, combined with the ~1 year of growth between sampling times, aimed to ensure that they were not from the same cohort.
Between 48 and 50 animals were analysed from each sample, giving a total of 624 animals. Tissue samples from adductor muscle and hepatopancreas were extracted on site and frozen in liquid nitrogen. Samples were stored at -70°C prior to electrophoresis.<b>Credit</b><br/>West Coast Abalone Divers Association<b>Credit</b><br/>Department of Fisheries WA<b>Credit</b><br/>Recreational Fishing Advisory Committee, WA<b>Purpose</b><br/>To assess the size of management areas, the scale of research studies and issues of translocation.

Patterns of establishment and subsequent change in the structure of a marine epifaunal community.
No full textStatement: GENERAL MATERIALS AND METHODS:
Sand-blasted paper bakelite ('tufnol') panels (30 x 20 x 0.6 cm) were used to monitor the epifaunal communities in this study. The panels were bolted to aluminum frames (1.65 x 0.98 m), each frame supporting 3 or 4 rows of 4 panels. Up to 6 frames could be fitted vertically into an angle iron rig (1.85 x 1.08 x 1.65 m) bolted to a specially constructed platform beneath the pier. The panel frames were placed in parallel with the direction of the tidal currents (east-west). The 4 rows of panels on a frame were 1, 1.4, 1.8 and 2.2 m below mean low water mark. The rigs were positioned beneath the pier decking where the light intensity was low and even, inhibiting algal settlement.
Panel immersion, removal and field observations were carried out using SCUBA diving. Immersion periods of panels in this study ranged from 2 to 42 months. At the conclusion of experiments panels were fixed in a 4% formalin-seawater solution and stored in this solution until sampled.<b>Credit</b><br/>Martin, A.A., DrArtificial substrata were used to investigate the patterns of establishment and change in the structure of a subtidal, marine epifaunal community at Portsea, Victoria from October 1975 to November 1979. Sessile invertebrate species and mobile species that significantly affected the distribution and abundance of the sessile species were the focus of the study. Experiments examining variability in recruitment and community development, species competitive ability, and the effects of predation on the epifaunal community at Portsea are outlined in the related records
