Secchi Disc data measured during a high rainfall event in Port Jackson, 21 August 2007
No full textStatement: A Secchi Disc was used to take the measurements of water clarity. The Secchi disc is a standardised water visibility estimate taken by lowering a white disc of about 30 cm diameter into the water and measuring the depth at which it becomes invisible.
Data parameter: secchi disc depth (m).Statement: A Secchi Disk measures water clarity. Water clarity may be affected by three different factors -- algae, sediment and / or water color.<b>Credit</b><br/>You, John<b>Purpose</b><br/>To analyse water clarity data collected during a high precipitation event over the Sydney Harbour catchment in order to determine how the Port Jackson estuary behaves under these conditions.The Sydney Harbour catchment area includes a number of different river systems which drain into the Port Jackson estuary. During high rainfall events the catchment areas behave differently to deliver contaminants into the Port Jackson estuary. Under conditions of high rainfall contaminants are delivered to areas very quickly as freshwater slides over the top of the denser more saline waters of the estuary. Secchi Disc samples were taken along the Port Jackson estuary over four days to determine the behaviour of the freshwater plume as it travels in a layer of freshwater to be flushed or flocculate out at some point in the estuary

This mooring held two S4 Interocean current meters at depths of 11.5m and 5.5m. <br/><br/>Each of these current meters provided two datasets. In the first, the meter integrates the signals over 2 minutes every 10 minutes, providing 10 min sample readings. The second decimated the samples using a running mean to provide hourly intervals. <br/><br/>The data provided includes the eastern and northern tidal components, speed, direction and temperature. The datasets providing the 10 minute sample values also give depth and salinity readings. <br/><br/>**Users should be aware that there appears to be some data corruption in the later stages of the datasets collected from 11.5m.

Shark Bay Scallop Sustainability
No full textMaintenance and Update Frequency: unknownStatement: Original record compiled for the Western Australian Marine Science Institution (WAMSI), Project 3.8, 2008. Originally sourced from WA Fisheries website (May, 2008). Spatial extent assumed to be whole of WA.<b>Credit</b><br/>M. KangasThe Shark Bay Scallop Managed Fishery is Western Australia's most valuable scallop fishery, based on the take of southern saucer scallop. Management of the fishery is complicated by two fishing fleets (prawns and scallops) having access to the scallop stocks. 14 vessels are licensed to fish for scallops only and the 27 vessels in the Shark Bay Prawn fleet can also retain scallops. Total landings for the 2003 season were 155 tonnes.<br/><br/>Catch in this fishery varies widely depending on the strength of recruitment. An annual research survey is carried out, which together with existing detailed biological knowledge, enable an annual catch forecast to be provided. This survey also enables the start date of the fishery to be determined and allows management of the spawning stock.<br/><br/>This project will:<br/><br/> * provide an overview annual report on the status of the shark Bay Scallop Managed Fishery;<br/> * provide management advice as to the long-term sustainability of the Shark Bay Scallop Managed Fishery;<br/> * direct research to maintain Shark Bay scallop resources at ecologically sustainable levels and to maximise economic and social benefits derived from this resource; and<br/> * provide scientific advice to the managers and industry on an ongoing basis.<br/><br/>Time: Ongoing
Modelling Western Australian Fisheries with Techniques of Time Series Analysis
No full textMaintenance and Update Frequency: unknownStatement: Original record compiled for the Western Australian Marine Science Institution (WAMSI), Project 3.8, 2008. Originally sourced from WA Fisheries website (May, 2008). Spatial extent assumed to be whole of WA.<b>Credit</b><br/>M. Craine (Project leader)The project involves the development of a set of time series models to predict future catch, effort and catch-per-unit effort of different key fisheries species. It is planned to investigate the catch-effort, catch-environment, stock-recruitment-environment, etc., relationships and to analyse historical data.<br/><br/>This can allow prediction of future catches of several key fisheries in Western Australia (including western rock lobster, prawns, herring, salmon, tailor). These time series models will provide low-cost effective methods for stock assessment of WA fisheries, especially for low-value fisheries. The time series models will allow better prediction of future catch/effort values and provide alternative performance indicators for fisheries management.<br/><br/>Time: completion June 200
