Impacts of seawater desalination on the giant Australian cuttlefish Sepia apama in the upper Spencer Gulf, South Australia

With seawater desalination expanding rapidly, it is important that ecological studies are undertaken to determine the effects of brine discharge on the marine species in the area. The abundance of giant Australian cuttlefish (Sepia apama, Gray 1849) eggs and environmental data were recorded at nine sites near Point Lowly, Spencer Gulf, South Australia, an area where the largest desalination plant in the Southern hemisphere is proposed. In addition, the effects of different concentrations of desalination brine on the growth, survival and condition of cuttlefish embryos were investigated. The primary egg-laying sites for the cuttlefish were in the vicinity of Stony Point (sites 4 and 3) and the area with the least egg abundance was on the eastern and western areas around Point Lowly (sites 9 and 7) where no eggs were found. The survival of embryos decreased with an increase in salinity, with no embryos surviving to full term in salinities greater than 50‰. Mean weight and mantle length also decreased with increasing salinity. Besides elevated salinity, the brine also had increased concentrations of Ba, Ca, K, Sr and Mg relative to water near Point Lowly. Brine discharge from seawater desalination poses a potential threat to the unique spawning aggregation of the giant Australian cuttlefish, in the upper Spencer Gulf, South Australia.

RAN CTD Profile Data - HMAS BENALLA ProjectID: HI568BEN_M From: 2015-02-26 To: 2015-04-14

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 231 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI568BEN_M from HMAS BENALLA.
The CTD was manufactured by Applied Microsystems Limited and is the "Micro CTD" model. This CTD type is referred to operationally as the MVP200_CTD. This CTD is fitted with a 4 electrode platinized conductivity cell, thermistor temperature sensor and a semiconductor strain gauge pressure sensor.
The CTD sensors are calibrated at the manufacturer Applied Microsystems Limited on a 12-18 month schedule. The CTD temperature sensor is calibrated against 'Hart' temperature standards. The pressure sensor is calibrated using 'Budenburg Deadweight' standards. The conductivity sensor is calibrated using 'Hart' temperature standards and seawater samples of known conductivity.
The CTD sensors are mounted to a fish-shape probe. The probe is controlled by an electric winch (MVP200 type). For downcasts the fish is allowed to free-fall (winch is in 'free-wheel' mode) under its own weight at about 2-3 ms-1 and then is winched back. Data is recorded in downcast and usually in upcast direction at a sampling rate of 25 Hz. The downcast data is of higher quality because sensors encounter undisturbed seawater that flows through the nose of the fish. On the upcast the fish is flipped around (tail first) and the sensors in the nose encounter disturbed flow from the fish tail.
This type of CTD is prone to a phenomenon called 'salinity spiking' caused by a mismatch between the response times of the temperature and conductivity sensor. Data undergoes a salinity de-spiking routine to correct for this. See the history metadata for further details on the salinity de-spiking process.
Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.

Predictive toxinology: calculated molecular descriptors to describe toxicity using Saxitoxins

Saxitoxins (STXs) were used to ascertain whether a combination of calculated molecular descriptors could explain observed biological activity. A dataset of 3050 molecular descriptors was generated for each of 30 Saxitoxins. Removal of descriptors that were the same for all toxins, or because a descriptor could not be calculated for one or more of the toxins, decreased the dataset to 1751 descriptors.
 To assess the utility of molecular descriptors to describe potency of natural toxins and then to use them to predict likely bioactivity of as yet untested toxins.
 The dataset of toxicity and molecular descriptors(30 toxins x 1751 descriptors) is available upon request.Molecular descriptors and their mathematical combination have been used for predictive toxicology and risk assessments of environmental pollutants and pharmaceutical leads. This was the first study to use this approach for natural toxins.

The effects of cyclone Winifred and bioturbation on sediments and sediment fauna of coral reef lagoons on the Great Barrier Reef

Tropical cyclone Winifred (Category 3) crossed the Great Barrier Reef north of Townsville on the 1st February 1986. Sediment samples were collected from the lagoons of reefs close to the track of cyclone Winifred and at reefs at a range of distances from the cyclone track.Three reefs in the path of the cyclone (Gilby Reef, Feather Reef and Potter Reef) were sampled within six days of the cyclone. Potter Reef had been sampled for another project prior to the cyclone and was sampled a third time 6 weeks after the cyclone. Rib Reef, the most distant of the reefs from the track of the cyclone had been sampled prior to the cyclone and was sampled again 14 days and 6 weeks after the cyclone. Noggin Reef and Otter Reef were sampled only once, 6 weeks after the cyclone.Observations on topography, sediment type and surface detritus of the lagoon sediments of each reef were made at 15 second intervals from a manta board towed at 2 knots. Sediment samples were collected for faunal analysis using a corer with a internal diameter of 5.5 cm. Cores were collected at a representative site within each reef lagoon at a depth of about 10m. Four groups of five, 20 cm long cores were collected at each site. Groups of cores were collected within an area of 1m² and groups were separated by approximately 4 m.Three surface sediments samples were collected from each reef lagoon for organic carbon and organic nitrogen analyses and analysis of grain size distribution.
 This research was undertaken to determine whether:1. cyclones impact on the sediment and sediment fauna of reef lagoons2. the impacts of cyclones on the sediment and sediment fauna are long lasting

Shark Bay Scallop Sustainability

The 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.
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.
This project will:
* provide an overview annual report on the status of the shark Bay Scallop Managed Fishery;
* provide management advice as to the long-term sustainability of the Shark Bay Scallop Managed Fishery;
* direct research to maintain Shark Bay scallop resources at ecologically sustainable levels and to maximise economic and social benefits derived from this resource; and
* provide scientific advice to the managers and industry on an ongoing basis.

Time: Ongoing.

Assessment of the effects of the 2004 coral bleaching event at Lihou Reef National Nature Reserve (Coral Sea) using towed video (Towvid)

Reefs in the Lihou Reef National Nature Reserve (NNR) were surveyed between 8-13 October 2004 in order to assess the effects of significant coral bleaching, which was observed during previous surveys in March 2004.A series of six video tows were conducted at depths between 45m and 60m, in the lagoon area of Lihou Reef NNR and also to the north of Anne Cay. A computer-based application, allowing keyboard classification was used to analyse the video tapes. Habitats were classified based on the substrata (3 categories) and overlying epibenthos (6 categories) viewed on the tapes.
 Towed underwater video (Towvid) was used to survey previously unsurveyed deeper waters of the Lihou Reef National Nature Reserve (NNR), for the presence of coral communities and to establish the extent of bleaching at depth.
 The Lihou Reef National Nature Reserve (NNR) is one of two protected areas in the Coral Sea region. The reserve is located in the Coral Sea 400 kilometres east of Townsville, Queensland. It was proclaimed on the 16th August 1982 under the National Parks and Wildlife Conservation Act 1975.The Coringa-Herald National Nature Reserve and Lihou Reef National Nature Reserve Management Plan states that both reserves are to be managed as strict nature reserves - World Conservation Union (IUCN) Category 1a - strict nature reserve. Such reserves are managed primarily to ensure habitats, ecosystems and native species are preserved in an undisturbed state as well as to facilitate research.

Temperature responses of two sympatric seagrasses, Amphibolis antarctica and Amphibolis griffithii, in relation to their biogeography

Seedlings of the viviparous seagrasses, Amphibolis antarctica (Labill.) Sonder &amp; Aschers. and Amphibolis griffithii (Black) den Hartog, were collected from near Dongara in 1990 and grown in seawater cultures at temperatures of 10-30 degrees Celsius. This was to test whether any differences in temperature responses (survival and growth) existed between these two species under controlled conditions, and if so, whether these could account for the observed differences in distribution.

Sea Turtles as Tropical Ocean Observers

This was project is a collaboration between the Australian Institute of Marine Science (AIMS), the Department of Defence, Integrated Marine Observing System (IMOS) and the Sydney Institute of Marine Science. The tea,m partnered with the Tiwi Islands Marine Rangers and the Tiwi Land Council partnered and the Crocodile Islands Rangers and Milingimbi Outstations Progress Resource Aboriginal Corporation (MOPRA). Traditional Owners of both areas gave consent for the team to work on their sea country and on these culturally important species.
We deployed satellite linked tags on female turtles after they had completed nesting on the beach. Tagged turtles included olive ridley turtles on the Tiwi Islands (in May 2022) and flatback turtles (in Oct 2022) and olive ridley turtles (in May 2023) at the remote Crocodile Islands. The tags track the turtle movements anand collect temperature and salinity data from the ocean as they dive.  This information will provide a better understanding of turtle habitats and behaviours around the islands and beyond to inform conservation and management and assist the dDepartment of Defence to understand the oceanography in the little-studied Arafura Sea.

Derwent Estuary Ambient Water Quality monitoring program - Site U12

Site U12 is sampled monthly by Norske Skog as part of the Derwent Ambient Water Quality monitoring program.
Since 2003, ambient water quality monitoring has been carried out on a monthly basis at up to 28 sites throughout the Derwent estuary by Norske Skog Boyer, Nyrstar Hobart and the State Government. Monitoring is carried out by three different boat-based sampling parties, but is co-ordinated to occur on the same day each month. 
At each site, in-situ field measurements are taken using calibrated sensors for temperature, salinity, pH, dissolved oxygen and turbidity. Water clarity is also measured using a secchi disk. Surface and bottom water samples are collected for analysis of true color, total suspended solids(TSS), total  and dissolved nutrients, organic carbon and zinc. at most sites, depth integrated samples are also collected for chlorophyll a using a plastic tube. Bottom samples in the Middle and Outer estuary are collected using a niskin bottle. Pumps are used in the upper estuary site to fill up the bottles. All water samples are analysed at Analytical Service Tasmania, a National Association of Testing Authorities-accredited laboratory. Monitoring site depth is 2 meters
