Crown-of-thorns starfish (Acanthaster planci) and coral cover surveys of the reefs of Vanuatu

The distribution and abundance of the crown-of-thorns starfish (Acanthaster planci) and the cover of living and dead coral were investigated at 29 sites around 13 islands of Vanuatu using spot dives, manta tows and belt transects in 1988.Survey sites were located in the vicinity of the following islands and reefs: Aneityum, Tanna, Erromango, Efate, Cook's Reef, Pentecost, Gaua, Ureparapara, Reef Islands, Espiritu Santo, Malakula and Epi.Rapid macroscale surveys of the upper reef slopes (At each site, the number of Acanthaster planci observed was recorded. The percentage cover of living and dead scleractinian corals was visually estimated, and depth, aspect and coral diversity noted. Particular note was made of any extensive areas of dead standing tabulate and staghorn Acropora spp. on reef slopes as these indicated possible outbreaks of Acanthaster planci in the recent past.Additional details of Acanthaster planci activity on Efate reefs were obtained from questionnaires and interviews with tourist operators and divers.
 This research was undertaken to investigate the status of Acanthaster planci in Vanuatu.
 This research was a component of a survey of Vanuatu Marine Resources conducted in March/April 1988 and was funded by the Australian International Development Assistance Bureau.The objectives of the survey were1. To survey and describe the shallow water reef habitats from selected islands of Vanuatu, adequately covering geographical and environmental variation2. To survey and describe the marine habitats around the shores of Malakula, including offshore islands3. To derive a coastal management plan for Malakula and offshore islands which can serve as a basis for Coastal Zone Management plans for the rest of the country4. To train Ni-Vanuatu personnel in marine survey and marine conservation methods

IMOS - Autonomous Underwater Vehicles - SIRIUS, CAMPAIGN: Western Australia, APRIL 2012

Temperate WA (Kendrick, Babcock, Smale): A cruise was undertaken in collaboration with the University of Western Australian and CSIRO to document benthic assemblages on temperate reefs off the coast of Western Australia in April, 2012. This cruise was the third in a 3 year series of IMOS Autonomous Underwater Vehicles (AUV) Facility cruises intended to establish a benthic habitat timeseries along the Eastern and Western coasts of Australia. These surveys have been repeated annually for three years. Surveys were conducted off Rottnest Island, Jurien Bay, and the Abrolhos Islands. Sites were surveyed at each location spanning three depths (15 m, 25 m, 40 m), both inside and outside MPAs, with three 25 m x 25 m full photo coverage quadrants devoted to each site. Site locations targeted kelp beds and were provided by the science party. The locations of individual quadrants within each site were selected to repeat surveys conducted in 2010 and 2011. Additional scientific operations carried out during the cruise consisted of CTD casts.

Planthouse experiments to determine the effects of oil and dispersed oil treatments on mangrove seedlings

In early 1996, experimental tidal tank systems were set up in the planthouse at the Australian Institute of Marine Science (AIMS) near Townsville, Queensland, to investigate the effects of a range of oils and dispersants on mangrove seedlings. Four species groupings of mangroves were used: Aegiceras corniculatum; Avicennia marina var. eucalyptifolia; mixed Ceriops species (Ceriops australis, Ceriops decandra and Ceriops tagal); and Rhizophora stylosa. Seedlings in two distinct age classes were used (approximately 18 months old and greater than 24 months old) and were planted in either sand or fine mud sediments. In May-June 1997, seedlings were treated with various combinations of preweathered oil and dispersant. The oils used were Bunker C fuel, Arabian Light crude, Gippsland Light crude, Thevenard crude, and Woodside condensate. The dispersants used were, Corexit 9527, Corexit 9580, BP-AB and Shell VDC. Combinations of these oils and dispersants were selected in consultation with project advisors in the APPEA Research Working Group.Seedling condition and growth were monitored until November 1997. Growth measurements included stem height, stem diameter and leaf production rate. Effects were measured by percent mortality of the seedlings. Leaves were collected from the seedlings and analysed to identify any notable changes in the amounts of key elements such as sodium, potassium or calcium.
 This research was a component of the project "Fate and effects of oil and dispersed oil on mangrove ecosystems in Australia" and was undertaken to provide an assessment of immediate and short term impacts of oil spills, and to rank toxic effects.The objectives of this experiment were:1. to assess the effects on common Australian mangrove species of a range of oils and dispersed oils most likely to be released in Australian waters. 2. to better understand what caused plants to die from oiling.

Derwent Estuary Ambient Water Quality monitoring program - Site U16/17

Site U16/17 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

WAMSI 2 - Dredging Node - Project 6.3 Defining Thresholds and Indicators of Filter-feeder Response to Dredging Related Pressures - FIELD SURVEYS, Western Australia

Project 6.3 - Field surveys: The objective of this work is to provide in situ community level data (major taxa and species, diversity, dominant growth forms, abundance, density etc.) for local filter feeders at two scales of survey (large scale: underwater video and scoring, small scale: SCUBA, sampling and analyses) and reveal which taxa or growth forms are habitat-forming and should be used for the experimental work (Project 6.4). The main focus will be on sponges, but other filter feeders will also be included at Class level (sponges vs. tunicates vs. cnidarians vs. bryozoans). In addition, this work will identify changes before vs. after the dredging work and therefore validate parts of the tank work. Subject to the consistency of responses across all filter feeders or immediately obvious patterns, we aim to identify of the most vulnerable organisms that may be used as biomonitors, and responses that may act as bioindicators for dredging-related stress. Samples will be collected to determine community attributes such as proportion of heterotrophy vs. phototrophy etc.
 Fieldwork was conducted during two trips (2013 and 2015) aligned with dredging activities at Chevron's Wheatstone Project to allow a 'before dredging' assessment in comparison to 'after'.. Field surveys were conducted at two scales using different methods and answering different questions. Large-scale surveys: Sampling was conducted using underwater towed video. Some general principles are that (1) sample before any dredging activities have started and afterwards, (2) subject to access and benthic communities found by video work we will sample in nearshore, mid and offshore zones, and (3) where possible sample areas where there are existing baseline data or areas that will be monitored throughout the program in the compliance with the monitoring program (monitoring is thought to be based on quarterly sampling), (4) emphasize sampling in the ZHI where dredging impacts are likely and where sampling is often not conducted during dredging programs (as these areas are effectively sacrificial). Small-scale surveys: Replicated IS x 1m belt transects will be investigated and sampled on SCUBA depending on preliminary findings from the video work and conducted according to WAM protocol.

Size, sex and geographic variation in the diet of the tiger shark, Galeocerdo cuvier, from Western Australian waters

Stomach contents from tiger sharks, Galeocerdo cuvier, caught on lines off the central coast of Western Australia were analysed to investigate variations in the diet due to sex, size and geographic location. Stomachs from 84 specimens contained food, while 26 had empty stomachs and 66 had regurgitated. Twelve prey groups were identified, the most common being turtles, sea snakes, teleost fishes, dugongs and sea birds. Dietary overlap was high between males and females. An ontogenetic shift was observed in the diet. Smaller prey (e.g. cephalopods, teleosts and sea snakes) were more common in small individuals, while the occurrence of larger prey (e.g. turtles, dugongs and elasmobranchs) increased with increasing shark size. Differences in the diet were observed between four regions along the central Western Australian coast. The ability to catch and consume large prey, prey availability, prey density, and prey profitability were identified as factors influencing the diet. The high level of occurrence of dugongs and turtles in the diet of G. cuvier, relative to their abundance, suggests that shark predation may play an important role in regulating populations of these species.
