The interplay of temperature, light, and substrate type in driving growth and reproduction of an important tropical crustose coralline alga

This study examined the influence of light, temperature, and substrate types on growth and reproduction responses of Titanoderma cf. tessellatum, an important crustose coralline alga to settle coral larvae. The experiment was at the National Sea Simulator of the Australian Institute of Marine Science, Townsville, Australia in August&ndash;October 2023. Fragments of Titanoderma cf. tessellatum were cultured at two temperatures (27.5 vs. 30 &deg;C) and two light levels (mean maximum midday irradiance of 10 PAR vs 40 PAR) on three different tile materials (calcium carbonate [CaCO3], concrete, or polyvinyl chloride [PVC]). Fragments were photographed every two weeks for 12 weeks to assess growth, changes in reproductive structures (i.e., conceptacles), sporeling settlement, and recruitment of juveniles. Newly germinated spores, or sporelings (&lt; 1 mm in size), were counted from week 6 onwards to determine sporeling settlement rate. As sporelings continued to grow and expand laterally to become juveniles (~1&ndash;5 mm in size), individuals coalesced. Therefore, as a proxy for recruitment, which took into account spore settlement and post-settlement survivorship and growth, we measured the total area covered by Titanoderma juveniles at week 12.

Between the devil and the deep blue sea: negotiating ambiguous physical and social boundaries within the shark fishing industry of Bass Strait, Australia.

This thesis addresses questions of identity and ontological legitimacy within the commercial shark fishing community of Bass Strait, Australia. The implications of competing discourses for the integrity of fisher identity, environmental conservation and public narratives on environmental 'crises' are considered. Ethnographic material is drawn on and developed with commercial fishers and, to a lesser extent, fisheries 'experts', to explore ambiguities in understandings of individuality and perceptions of the marine environment. Informing this analysis are theories of practice, particularly notions of embodied relationships and knowledge, the role of 'luck' in enabling a particular expression of 'individuality', the 'skipper effect', a consideration of nation-state sanctioned and popular media representations of the environment, and the peculiarly Australian experience and representation of individuality, both as performance and as trope. These themes are considered against a backdrop of the physical and social activities involved in commercial fishing, and the 2001 nation-state-initiated introduction of an Individual Transferable Quota management system.

Stable Adult Growth but Reduced Asexual Fecundity in Marginopora vertebralis, under Global Climate Change Scenarios

Marginopora vertebralis were collected during two subsequent years (2016, 2017) from Fantome Island, from depths between 1&ndash;3 m. Acclimation periods of 17 days (2016) and 4 days (2017) were allowed, prior to being included in the mesocosm experimental system. The experimental system included corals, sponges, echinoderms, seagrasses green alga along with carbonate sediment.
M. vertebralis specimens were stained for 24 h with a fluorochrome marker (calcein (10 mg/L-1)) prior to 100 &ndash;150 M. vertebralis specimens were placed into tanks of each mesocosm system.
Three replicate tanks of each simulated water temperature and pCO2 levels projected:
2050 (+1 &amp;deg;C and 670 &amp;mu;atm)

2100 conditions (+2 &amp;deg;C and 900 &amp;mu;atm)

control treatment ambient conditions

Experiment duration were 5.5 months (2016), and 4.5 months (2017), after which all living specimens of the adult population were collected, washed in freshwater, air dried and photographed under a fluorescent microscope.
Categorical reproductive index scores were scored on multiple occasions (2017): 0. no juveniles detected, 1. few present (&lt;5), 2. some present (5&ndash;40), 3. many (40&ndash;100), 4. &gt;100. And at the end of the experiment the total number of juveniles (&lt;3 mm) and adults were counted, along with growth measurements.
Statistical analyses were performed in R where binomial models were used to test for significant differences in the probability of foraminifera reproducing depending on the climate change scenarios. For full details see the paper Reymond et al, (2022).

Surveys of Octocoral communities, benthic cover and environmental factors on coral reefs of Torres Strait

All surveys were carried out by the principal researcher using Rapid Ecological Assessment. The dataset comprises 33 entries from 7 reef locations.On each reef 1-3 sites were surveyed with up to 5 transects (usually 200-300m long, 1-3m wide for 10-15 minutes) per site at pre-defined depths (1-3m, 3-8m, 8-13m, 13-18m and reef flat).Species recorded: octocorals (soft corals, gorgonians, sea fans, sea whips, sea pens, leather corals, arborescent octocorals, blue coral, stoloniferans), black and wire coral. Note that species are mostly at generic level.Site variables comprise: visibility (a modified Secchi technique - estimating maximum visible distance of a bright object in metres); depth; exposure (very exposed, protected, exposed, moderate); orientation (E, NNE, etc.); formation (Point, Face, Bay/Inlet, Channel); slope angle (assigned to 5° categories); flowspeed (estimated by 5 timings of the traveling speed of suspended particles along a ruler at cm/second); wave exposure (0=sheltered to 4=very exposed); sediment deposit (0=none, 1=thin layer, 2=considerable, 3=thick layer); rubble % cover; sand % cover.Visual estimates of overall abundance (percent cover) were estimated in 2.5% increments from 1-10%, 5% increments from 10-30% and 10% increments over 30%). Categories are: hard corals, soft corals, dead coral, turf algae, coralline algae, macroalgae (conspicuous macroalgae - Halimeda and sargassum - were recorded separately), and total percent cover including sand and silt.Octocoral genera (in some cases species) were given a taxon abundance ranking (0=absent, 1=rare, 2=uncommon, 3=common, 4=abundant, 5=dominant).Zooxanthellate and azooxanthellate richness was calculated based on the numbers of octocoral taxa with (or without) zooxanthellae.Where applicable, samples taken for taxonomic purposes are noted.Site locations: Cumberland Passage, Dungeness, Tuesday Islet No. 4, Thursday, Warrior, Wednesday, Zuna.
 To survey the cover of the main benthic groups, richness and abundance of octocorals in the reefs of Torres Strait and related spatial and water quality gradients.Because roughly half Octocorals have photosynthetic symbionts they are ideal to assess how biodiversity is related to spatial and environmental factors, and photosynthetic symbionts and energy supply.To examine principal drivers of biodiversity, community composition, and ranges ofcoral reef benthos.
 Comparable data are held for the Great Barrier Reef, Hong Kong, Palau, Papua New Guinea, and Rowley Shoals (Western Australia).A subset of the data has been provided to the Ocean Biogeographic Information System (OBIS, http://www.iobis.org/OBISWEB/DisplayMetaData.jsp?content=meta/1458.html).

Future Reef MAP - January 2014 (Southbound)

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.

Development of Grain Protein Concentrates for the Aquaculture Feed Industry

This project coordinates, manages and implements research that addresses the development of the potential of Western Australian produced commodities, such as lupin and canola meals, for inclusion in aquaculture feeds, both domestically and internationally. This project has progressed substantially over recent years and grain markets are now established in Australia and Europe. Present annual estimated value of these markets is ~$12 million.
The project involves:
* substantial liaison with the grain production and processing industries and the aquaculture feed production industries to identify key opportunities to facilitate the expansion of use of grains in aquaculture feeds; and
* the development and assessment of value-added protein meals from lupins by evaluating of the nutritional value of key products when fed to rainbow trout and processing limitations on the production and use of those grain products.

All research work is being conducted in WA through UWA's Centre for Legumes in Mediterranean Agriculture (CLIMA) using the Department of Fisheries nutrition research facility at the Pemberton Freshwater Research Centre. Expansion of the project will see further commercial partners involved in 2003/2004 and additional product evaluation work undertaken in Tasmania and Norway.
Time : ends June 2006.

2016 SoE Marine Chapter - Pressures - Commercial fishing

The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "Pressures on the marine environment associated with commercial fishing". The full Expert Assessment, including figures and tables (where provided), is attached to this record. Where available, the Data Stream(s) used to generate this Expert Assessment are accessible through the "On-line Resources" section of this record.

DESCRIPTION OF THE PRESSURE
Australia’s wild-caught marine fisheries are highly diverse and contribute significantly to the economy. These fisheries catch scallops, prawns, crabs, squid, coastal fish such as whiting and flathead, reef fish such as coral trout, shelf and deepwater fish such as ling and blue-eye trevally, and oceanic tuna and billfish Although fisheries operate across all states and the Northern Territory and out to the limit of the Australian EEZ, fishing effort is not evenly distributed across Australian marine waters with the majority of fishing effort occurring in the North, Temperate East, South-East, and South-West Marine Regions. The impact of fisheries on the marine environment also varies with differing gears having differing impacts on species that might be caught as bycatch, and the habitats where fishing takes place. Methods used to capture those species are highly varied ranging from small-scale netting to large-scale pelagic long-line fishing and trawling (Flood et al. 2014). There is currently extensive effort occurring the Coral Sea bioregion using pelagic long – line gear. There have been extensive reductions in the footprint of the trawl fishery in the South West, South East and Temperate Eastern Bioregions. There is also an extensive trawl fishery in the North Bioregion, associated with the Northern Prawn Fishery, which remains relatively constant through time.

Temperature and spatiotemporal variability of salicylihalamide A in the sponge Haliclona sp. in southern Western Australia

Since the discovery of the sponge Haliclona sp. at Rottnest Island in 1989, new populations have been identified  in southern Western Australia, at locations Bremer Bay, Hamelin Bay and Jurien Bay. Samples from these four locations were collected and investigated for the production of the bioactive compound salicylihalamide A. These collections represent a sponge distribution that covers 1,200km of the coastline. During collection, the depth of each sponge, water temperature and sponge size was also recorded.
Two morphologies of the original songe have been identified, one with a deep green coloration, the second with a brown coloration. Chemical extraction and analysis was conducted to determine the concentration of the salicylihalamide A compound, using high performance liquid chromatography (HPLC), ultra violet (UV) detection and mass spectrometry (MS). Correlations between the concentration of the compound and water temperature, size and depth of the sponge sample origin was also examined.
The objectives of this research were
1. to determine whether both morphologies of Haliclona sp. produce salicylihalamide A
2. to describe the spatial and temporal patterns of salicylihalamide A production in Haliclona sp.

Rapid colour changes associated with the fiddler crab, Uca capricornis

The purpose of this experiment was to quantitatively examine the rapid colour changes associated with the fiddler crab, Uca capricornis. Experiments were conducted in the East Point Reserve, Darwin from Nov - Jan (04/05 and 05/06). 
65 randomly selected crabs were caught (21 males and 44 females) and their ability to change colour over a 20 minute period was assessed using a portable spectrophotometer. 
The results indicate that when caught, or otherwise stressed, U. capricornis are capable of rapidly changing their colour, with short term colour changes more likely in females. In all cases the pattern remained unchanged, but did become more difficult to distinguish as the colours darkened.

Community change in the algal endosymbionts of a scleractinian coral following a natural bleaching event on the Great Barrier Reef

The symbiont community of 460 randomly sampled colonies of Acropora millepora from a reef flat adjacent to Miall Island (Keppel Islands, Great Barrier Reef) were analysed after a natural bleaching event in early 2006. To determine the Symbiodinium community composition, 460 colonies were tagged on the reef flat at Miall Island between September 2004 and March 2005. A combination of single-stranded conformation polymorphism (SSCP) analysis, cloning and DNA sequencing was used for symbiont identification. Symbionts were: the thermally sensitive Symbiodinium type C2, a tolerant Symbiodinium type belonging to clade D, mixtures of C2 and D, and C1. Background types were also recorded.A subset of 79 colonies that survived the bleaching 3 and 6 months (May and August, respectively) after the bleaching event in January/February 2006 were examined for symbiont changes. These colonies were chosen haphazardly from surviving colonies and comprised 58 with predominantly C2-type, 15 with predominantly D-type and 6 with both C2 and D types present.Mortality in the Acropora millepora population was assessed 6 months after the bleaching event in August 2006 by visually estimating the percentage (&lt;10%, 11-50%, 51-99%, 100%,) of live and dead coral tissue on 159 haphazardly chosen tagged colonies using pre-bleaching photos of each colony as a reference.
 To characterize the Symbiodinium community in an inshore population of Acropora millepora and compare the Symbiodinium community in the same tagged colonies before and after a natural bleaching that took place in 2006.
 The first field study to follow changes in Symbiodinium genotypes in specific colonies over a 3 year period that includes a natural bleaching event.

RAN CTD Profile Data - HMAS PALUMA ProjectID: HI544PAL_M From: 2014-04-09 To: 2014-06-04

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 76 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI544PAL_M from HMAS PALUMA.
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.
