Physical and chemical parameters at five Pacific oyster (Crassostrea gigas) growing areas in Tasmania - Pittwater, Pipeclay Lagoon, Little Swanport, Georges Bay and Simpsons Bay - were measured as part of a study to determine the carrying capacity of the areas for oyster farming. The data represented by this record was collected from Pittwater. This has provided valuable environmental data for these areas. The hydrodynamic regimes at each area except Simpsons Bay were studied, including high and low water volumes, flushing rates, flow rates and depth contours. Temperature, salinity and concentrations of nitrates, phosphates, silicates and chlorophyll a were measured monthly at several sites in each area. The change in these parameters over different time scales also was examined at two sites in Pittwater and indicated temporal and spatial variability in the environmental parameters measured.

Mesozooplankton community composition and structure were examined throughout the D’Entrecasteaux Channel, Huon Estuary and North West Bay, Tasmania, from November 2004 to October 2005, the data represented by this record was collected on the 21/01/2005. The composition of the mesozooplankton community was typical of inshore, temperate marine habitats, with seasonally higher abundance in summer and autumn and lower numbers in winter and spring. Copepods were the largest contributors to total abundance across all seasons and stations, while cladocerans and appendicularians were proportionally abundant in spring and summer. The faecal pellets of these three main groups, along with those of krill and amphipods, also contributed significantly to material recovered from sediment traps. Meroplanktonic larvae of benthic animals showed short-term peaks in abundance and were often absent from the water column for long periods. Spatially, North West Bay and the Channel had a higher representation of typically marine species, including Calanus australis and Labidocera cervi, while truly estuarine species, such as the copepod Gladioferens pectinatus, were more important in the Huon Estuary.

This data represents research conducted as part of a PhD project on captive Striped Trumpeter (Latris lineata). Trials were conducted to investigate hormonal induction of spawning using LHRHa and the effects on testosterone and estradiol in wild and captive fish. Data was also collected on the number and quality of eggs, sperm counts and photo thermal data to record the effect on reproduction.

In 2006, transect surveys were conducted at sites in eastern inshore Tasmanian waters at depths and habitats typical of those where abalone are commercially fished. Surveys focused on four areas of the Tasmanian coastline including St Helens, Bicheno and Dunalley on the east coast and the Actaeons region on the south-east coast; with at least 10 reefs sampled in each region.

The spatial extent of C. rodgersii "barrens" was estimated by surveying rocky reef habitat with a towed underwater video system. Sampling took place at 13 regions along the east coast of Tasmania, each comprising 3 subsites, this dataset refers to the South Bruny Island region, and its 3 subsites: Mangana Bluff, Bay of Islands and Cape Conella.

Raw acoustic data files for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore.

The impacts of a small, free-field, surface explosion from a ship scuttling, on two crustacean species was examined. The southern rock lobster (Jasus edwardsii) and the spotted shore crab (Paragrapsus gaimardii) were used to compare the effects on crustaceans in a controlled experiment on animals distributed up to 500 m from the blasts. Methods for assessing damage included; mortality, behavioural experiments, and physiological assessments.

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. Methods were initially developed for research on temporal changes following protection in Tasmanian long-term MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island), and the data represented by this record has been collected at Ninepin Point. In many cases the dataset involves temporal replication (year scale), particularly for the core Tasmanian MPAs represented by this record.
