Nephelometer data sets for Dredge_West around Cleveland Bay - 1993
No full textMaintenance and Update Frequency: notPlannedStatement: Data measurements were taken once every 5 minutes.
Column 1 contains the date and time of
a measurement as a 14 digit numeric string. Column 2 represents
the same date and time, but as a decimal day number, where 1.00000
represents midnight of 1 January 1993. Column 3 represents the
suspended sediment concentration (SSC) in mg/l.
In the file when "-999999" appears in all three columns
that represents the end of a data set download. Each `break' is
followed by the file header. This allows individual data sets to
be easily identified.

19930205062704 36.26880 9.31<b>Credit</b><br/>Arnstein Prytz<b>Purpose</b><br/>The study was to sample water quality during dredging of Cleveland Bay.This metadata record covers a subset of the data collected during dredging by the Townsville Port Authority in Cleveland Bay in 1993. Data are divided into a number of main groups: Wind, tide gauge, wave rider, S4, sediment traps, water samples and nephelometers. The data are grouped according to collection method and sampling location. See the metadata record title for collection method and geographic extent for the sampling location. Unique site numbers were assigned within Cleveland Bay at which data were collected. Some of these sites were named, and others were unnamed
Theme 3A: Restoration of intertidal and subtidal habitats.
No full text<b>Credit</b><br/>Centre for Research on Ecological Impacts of Coastal Cities<b>Purpose</b><br/>To develop better means of defining goals, assessing methods and achieving desired outcomes in restoration of intertidal and subtidal habitats.Deterioration of coastal marine and estuarine habitats is inevitable in areas where human development is active. This is particularly the case in New South Wales (and throughout Australia) where a very large proportion of the population live on the edges of the coast-line. To sustain biodiversity and to maintain ecological processes and functions (for its own sake or for anthropocentric, human reasons), it will be necessary, for a very long time, to recreate, rebuild or repair habitats (Programme 3: Restoration of Disturbed Coastal Habitats). The science of restoration of coastal habitats is virtually unknown, and there is no sensible theory or understanding of how to create habitat that develops ecological function and maintains natural biodiversity. <br/><br/>The biodiversity of animals and plants on rocky shores and in subtidal kelp-beds is vast, complex and variable in space and time. It is very different on many artificial hard surfaces (pilings, sea-walls, etc.) from that on natural rocky shores. As a result, it is necessary to find ways to change the construction of these essential infrastructural developments to enhance their capacity to provide suitable habitat for the natural fauna and flora of our coast-line.<br/><br/>The Centre for Research on Ecological Impacts of Coastal Cities (EICC) has generated many scientific papers and theses from research projects on the restoration of intertidal and subtidal habitats.

Theme 1B: Ecological patterns and processes in intertidal and subtidal soft-sediment habitats.
No full text<b>Credit</b><br/>Centre for Research on Ecological Impacts of Coastal Cities<b>Purpose</b><br/>To understand ecological changes in response to urban development and human use of the coast, it is crucially necessary to be able to understand ecological processes that bring about or cause a lack of, change in response to disturbances.Research is focussed on the processes causing and maintaining patterns of distribution and abundance of animals and plants in coastal habitats (Program 1 - Ecology in Coastal Habitats). Without a good understanding of the ecology of species in these habitats, the interactions among the species and the relationships among patches of similar or different habitat, it is not possible to solve problems in the management of coastal change.<br/><br/>Local mangrove forests, salt marshes and mud-flats are habitats for a large variety of animals and plants about which relatively little is known. Apart from research into patterns and processes in these ecological systems and work on environmental impacts and restoration, members of the Centre are doing experimental work on the consequences of fragmentation of habitat, connections with and interactions between different estuarine habitats.<br/><br/>The Centre for Research on Ecological Impacts of Coastal Cities (EICC) has generated many scientific papers and theses from research projects on intertidal and subtidal soft sediments.

Daily and Seasonal Cycles of Sand Temperatures on Sea Turtle Nesting Beaches in Western Australia
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 several databases compiled by WA DEC Marine Science Branch of projects relevant to the marine parks of WA. Variable metadata information was available.<b>Credit</b><br/>Gerald Kuchling: School of Animal Biology, The University of Western Australia (UWA)<b>Credit</b><br/>Keith Morris: Fauna Conservation Program, Science Division, Dept of Environment and Conservation (DEC)A study was undertaken on the temperature profiles of sea turtle nesting beaches in Western Australia. <br/><br/>Four species of sea turtles - Loggerhead turtle Caretta caretta, Green turtle Chelonia mydas, Hawksbill turtle Eretmochelys imbricata, and Flatback turtle Natator depressus - have nesting populations of global significance in Western Australia. So far sea turtle research in Western Australia has focused mainly on the tagging of nesting females to estimate the size of nesting populations and to generate data on migration and on monitoring individual nests. Virtually nothing is known on the demography of sea turtle populations, including sex ratios of adults, juveniles and hatchlings.<br/><br/>Sea turtles have temperature dependent sex determination, with warmer egg incubation temperatures producing females and cooler temperatures males. Sex ratios of nests are influenced by climatic conditions of nesting beaches and may show substantial seasonal variations. Sea turtles are known to nest along the Western Australian mainland coast and on many islands from the Shark Bay to<br/>the Kimberley. Several species have extended nesting periods (peak nesting along the west coast generally occurs between October and March) and nest along a gradient of latitudes. This suggests that nest temperatures and hatchling sex ratios of sea turtles in Western Australia may vary spatially and temporally.<br/>We measure sand temperatures at nest depth (standardised at 50 cm depth) at most major sea turtle nesting beaches on the Western Australian mainland from Carnarvon to the Dampier Peninsula and on the Dirk Hartog, Muiron, Barrow, Rosemary, Lowendal, Montebello, and Lacepede Islands for up to 2 1/2 years. Thermochron iButtons log temperatures in four hour intervals. Depending on beach profiles and the area used by sea turtles for nesting we deploy one logger at 50 cm depth just above the high water line where the lowest nests are found and a second 59 cm deep logger plus one at 10 cm depth near the highest nests at the dune crests. Data collection started in September 2004 and will be completed in 2007.<br/><br/>Southern beaches are generally cooler than beaches further north. Sand temperatures increase during the start of the peak nesting season and highest sand temperatures (> 30°C) are generally measured in February and March. Among year variability includes the passage of cyclones. No major cyclone passed through the study area in 2004/05, but several in 2005/06 and 2006/07. During and after cyclones sand temperatures drop down significantly.<br/><br/>This study will provide an overview of temperature variations at sea turtle nesting beaches and will only allow rough estimates of sex ratio variations according to published male and female producing temperatures for the different species. The data will indicate potential geographic and seasonal differences in the production of male and female hatchlings at nesting beaches and provide a baseline for more targeted research into hatchling sex ratios at particular beaches
