The effect of anthropogenic structures on reproductive output of the northern Pacific seastar (Asterias amurensis) in the Derwent River estuary, SE Tasmania

In the Derwent Estuary (south eastern Tasmania, Australia), the introduced northern Pacific seastar Asterias amurensis is highly abundant and fecund when associated with anthropogenic structures (wharves and marinas). Based on modelled predictions of fertilisation success, seastars at wharf 'hotspots', whilst representing &lt;10% of the total population in the Derwent Estuary, and concentrated in &lt;0.1% of the total area, contribute up to &gt;80% of total larval production in the estuary. 
Reproductive potential of populations at wharf and control sites was quantified (in terms of individual capacity and spatial characteristics of the population. A large scale survey was undertaken in the Derwent estuary (to 27m) to determine spatial distribution of the species. Zygote production (i.e. number of fertilised eggs) was used as a measure of reproductive output and was simulated using empirical estimates of spatial and reproductive parameters of the adult seastars in a spatially explicit model of fertilization (developed by A. Morris and C. Johnson).

Scalefish research activities

Projects including exploratory trawl surveys of the shelf and slope waters off southern Australia, targeted studies of specific fisheries, e.g. trawl fisheries for blue grenadier and orange roughy, purse seine fishery for jack mackerel, gillnet fishery for blue warehou, the coastal reef fishery for live fish fishery, inshore shark fishery, along with commercial catch sampling (on board and market sampling) have yielded an extensive dataset that includes biological, distribution and abundance information for a diverse range of finfish species from South East Australia.
These data have been compiled into a single database and cover collections made between the late 1970s and mid 1990s.  Note, selected data for key species (e.g. banded morwong, bastard and striped trumpeter) have been extracted and uploaded into Access databases (refer to scalefish research database, post mid-1990s).

IMOS - Southern Ocean Time Series (SOTS) - Quality Assessment and Control Report - Sediment Trap Particle Fluxes

This report details the quality assessment and control procedures applied to the particle flux data collected by the Sub-Antarctic Zone (SAZ) moorings between 1997 and 2018. The quality controlled datasets are publicly available via the AODN Data Portal. This report should be consulted when using the data. 
The Southern Ocean Time Series (SOTS) Observatory located at 140°E and 47°S provides high temporal resolution observations in sub-Antarctic waters. It is focused on the sub-Antarctic Zone because waters formed at the surface in this region slide under warmer subtropical and tropical waters, carrying CO2 and heat into the deep ocean, where it is out of contact with the atmosphere. This process also supplies oxygen for deep ocean ecosystems, and exports nutrients that fuel ~70% of global ocean primary production. The sub-Antarctic Zone and these processes are expected to change with global warming, but the potential impacts of these changes are not yet known.

Parent record: Vertical coherence of currents in Jervis Bay: Winter deployment of an Acoustic Doppler Current Profiler (ADCP)

This record describes components of the 'Jervis Bay Baseline Studies' project conducted by the Department of Defence, CSIRO and Australian Defence Force Academy (ADFA). The initial aims of the project were to obtain current and wind observations from Jervis bay over a six week period in order to detail the wind driven circulation and provide a data set for comparison with the numerical modelling work being simultaneously undertaken. However, after this initial experiment it became clear that there were significant currents in the bay that are not simply related to direct wind forcing. Therefore, alternative mechanisms for driving the flow had to be investigated, through the measurement programs and data analysis, as well as through numerical modelling. The result was a series of approximately six separate experiments aiming to define the water circulation around the bay and through the bay entrance, to gain an understanding of the processes that drive the currents, and to investigate the influence of stratification on the nature of the currents.
The fifth of these six experiments involved the winter deployment of an Acoustic Doppler Current Profiler (ADCP), moored in the central part of Jervis Bay (35o 05'S, 150o 44'E). An ADCP measures how fast water is moving across an entire water column. Anchored to the seafloor it can measure current speed not just at the bottom, but also at equal intervals all the way up to the surface. For this experiment, the ADCP was moored on the seabed, in a frame, with sensors looking upwards and approximately 0.5m above the seabed.
Over the winter deployment, 26th July 1991 to 26th September 1991, the ADCP was set-up with a 60 minute sampling interval and currents were measured over 1m depth bins. Bin numbers and currents are referenced as a height above the seabed (due to the uncertainty in defining water depth because of tides and air pressure). As such Bin #1 is centered at 1.5m above the transducer face or 2.0m above the seabed. Bin #2 is centered at 3m above the seabed, Bin #3 at 4m and so on.
The water depth was measured as 24m on deployment and the first 19 bins provided good data. Currents from bin 20 up were very noisy and it is inferred that contamination had occurred. These bins were removed from the dataset.
As this is a parent record, no data is available to download. A pdf outlining the structure and hierarchy of metadata records relating to this project is available through this record. Also available is a pdf of a published working paper documenting this experiment and the results. There is only one subsiduary records that directly relates to this parent, through which the data is provided (see hierarchical tree):

Hermatypic corals of the Rowley Shoals, Scott Reef and Seringapatam Reef, Western Australia

Two trips were made to the north-western Australian shelf atolls to identify the hermatypic corals occurring on these reefs. In July, 1982 the Rowley Shoals were were visited and sites on two of the three main reefs (Mermaid Reef and Clerke Reef) were surveyed. In September 1984, the three main reefs of the Scott Reef complex (North Reef, South Reef and Sandy Islet) and nearby Seringapatam Reef were surveyed.Sites were selected to encompass the range of habitats available. Habitats included reef flat zones, lagoonal habitats (pinnacles and soft substrates) and outer slopes with differing exposures to wave action. The number of sites visited at each reef were: Mermaid Reef (2), Clerke Reef (16), North Reef (11), South Reef (5), Sandy Islet (5) and Seringapatam Reef (2). Surveys were primarily undertaken using SCUBA, which was supplemented by snorkelling and reef walking. Corals were initially identified in situ. If further investigation was required, samples were collected and sent to the Australian Institute of Marine Science.
 The purpose of this research was to compile an accumulative species inventory, with the aim of reaching a complete list for each reef.
 The hermatypic coral surveys were a component of a survey of the fauna of the north-western Australian shelf atolls conducted by the Western Australian Museum.

Secchi Disc data measured during a high rainfall event in Port Jackson, 23 August 2007

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.

Parent record: Datasets relating to core GC-12, located in the Capricorn Channel at a depth of 990.5 mbsl

Core GC12 (23o34' 37S 153o49' 94E) was collected from the Capricorn Channel at a depth of 990.5 mbsl (metres below sea level). By investigating the properties and components of this core we are able to reveal some information about this hemi-pelagic sedimentary environment over the last glacial / interglacial cycle. Information obtained or inferred from the core include the isotopic composition of oxygen and carbon through time, an age vs. depth profile, the percentage of grainsize fractions throughout the core and the percentage of carbonate material in each sample. X-Ray Diffraction (XRD) analyses were also run on several samples from each core to determine changes in the carbonate mineralogy and terrestrial influx, which provided further palaeoclimatic information.

Future Reef MAP - July 2013 (Northbound)

Data were collected as part of the FutureReef MAP project, a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef. The Future Reef MAP project is funded by Rio Tinto Alcan and administered by the Great Barrier Reef Foundation, with an equal co-investment by CSIRO. The project is the first large-scale CO2 observing system established on the Great Barrier Reef using the Rio Tinto ship, RTM Wakmatha. The research is targeted at providing information on the CO2 uptake and the controls on ocean acidification change in the region. It is providing foundation data needed to assess the vulnerability of the GBR reefs to ocean acidification. This dataset contains quality controlled underway measurements of the fugacity of CO2, atmospheric pressure, and sea surface temperature and salinity. The data management and distribution of these data were supported by the CSIRO Carbon Collaboration Cluster and the Australian Coastal Ecosystem Facility.

 Glomar Shoals and Rankin Bank have been identified as potentially sensitive environmental receptors of interest to Woodside Energy Limited (WEL). The Australian Institute of Marine Science (AIMS) also noted a lack of biodiversity data on these banks and shoals, despite Glomar Shoal being identified in the national bioregional plan, as a key ecological feature in the mid-shelf Pilbara region. The current study was initiated in 2013, supported by WEL and AIMS to understand and document the present status of the physical and biological characteristics of the submerged reefs. The baseline data will facilitate longer term monitoring of natural variability against which future changes can be assessed.

WAMSI Node 4.2.4 - Demersal fish assemblage sampling method comparison and power analyses - Summary

The principal goal of this research was to investigate the most efficient, cost-effective and meaningful way of describing the structure and biodiversity of seabed habitats along the coastline of WA. This study used existing data obtained from three regions (Ningaloo, Abrolhos and Capes) to compare techniques including comparing diver vs camera-based techniques for fish. 
The first study compared the assemblage composition, relative abundance and size of fishes sampled using baited video and diver swum transects at the Houtman Abrolhos Islands and Ningaloo. At both locations stereo BRUV recorded many more targeted fishes than stereo DOV and in greater relative abundance (e.g. Lethrinus nebulosus, Plectropomus leopardus). Many non-targeted species were also attracted to bait (e.g. Coris auricularis) and were recorded in greater abundances on stereo BRUV than stereo DOV. Stereo DOV transects recorded a greater abundance of some small-bodied Pomacentridae, Labridae and Scaridae species than did stereo BRUV, particularly at Ningaloo. This study demonstrates that choice of stereo-video sampling technique for surveys of reef fish can have a large impact on the structure of fish assemblages surveyed.
A link to the paper "Assessing reef fish assemblage structure: how do different stereo-video techniques compare?" by Dianne L. Watson, Euan S. Harvey, Ben M. Fitzpatrick, Timothy J. Langlois and George Shedrawi is given in a URL below (see online resource) and provides further details
The second study compares baited video stations with diver swum transects across three biogeographic regions, where both methods use stereo-video techniques to provide accurate estimates of individual fish length and define the sample unit area (Langlois et al. submitted). Cost-benefit analyses showed that baited stereo-video methods were generally more cost-efficient than diver operated stereo-video transects for detecting change in the fish assemblage. The study suggests that baited stereo-video stations are, in general, a better method for monitoring fish communities than diver operated stereo-video transects.
