Davies Reef Deployments of the Wireless Sensor Network

Sensor network infrastructure was installed at Davies Reef in the central Great Barrier Reef off Townsville, Australia. The infrastructure consists of a base station mounted on the existing reef communications tower and a number of buoys which carry the actual sensors.
The initial design is to monitor the flow of water through the lagoon, the connectivity between the lagoon and the open ocean and the presence of an upwelling signal as oceanic water crosses the open shelf in the Townsville region. This site is linked to ones on the edge of the shelf (Myrmidon Reef) and sites closer in such as Rib Reef and Orpheus Island.
The deployment in December 2009 consisted of the base station using the Telstra nextG service and five buoys or sensor floats. The sensor floats carry a mixture of sensors but typically a surface MEA Thermistor and a bottom mounted SeaBird SBE39 (temp + pressure), for some floats the SBE39 is replaced by a SBE37 to give salinity (as conductivity), temperature and presure.
On the tower is a vaisala WXT520 weather station.
The project looks to deploy sensor networks at seven sites along the Great Barrier Reef to measure a range of physical parameters at a range of scales. The project will install communications, data and platform infrastructure that will support future sensor work looking at biological and chemical parameters.

Aquatic Animal Health

This project is concerned with enhancing the emergency disease response capability of the Department of Fisheries and industry bodies associated with non-maxima oyster culture.
Relatively few major disease outbreaks have occurred within the WA aquaculture industries and as a result there has been limited opportunity for an integrated multi-agency approach. The Department has also been fortunate that the remote and isolated nature of most of WA has not seriously affected the limited emergencies so far experienced.  Simulation exercises provide a practical method of exposing and training staff in the management of aquatic disease emergencies.
An exercise was held in November 2002 at Geraldton, with the active involvement of the Department of Agriculture and AMWING, the industry body representing non-maxima pearl oyster producers.
The project will:
      o Increase knowledge of emergency management procedures within WA Fisheries and within the non-maxima oyster industry.
      o Improve WA Government and industry emergency management procedures.
      o Incorporate outcomes into the development of environmental management systems by non-maxima industry that is being undertaken as part of Environment Australia eco-efficiency program.

  Time : due for completion in 2004.

The behaviour of mixtures of paralytic shellfish toxins in receptor dependent assays

Using two unrelated STX-binding proteins (the rat brain Na channel and a saxiphilin from the xanthid crab Liomera tristis), this study experimentally validated the predicted combined effects of binary and ternary mixtures of paralytic shellfish toxins (PSTs). All toxin dilutions (tritiated saxitoxin ([3H]STX), STX dihydrochloride, neoSTX, dcSTX, and GTX5) were in 0.01 M acetic acid. The L. tristis saxiphilin assay was conducted in high protein binding 96 well filtration plates and the rat brain Na channel binding of [3H]STX was measured using a microtiter plate method.The model predicts the amount of inhibition by toxin mixtures in competitive binding assays from which an IC50 (concentration that inhibits radioligand bindingby 50%) can be calculated. IC50 values and their 95% confidence limits from experimental data were derived using the single site curve equation of Graphpad Prism (Ver 4.0, Graphpad Software, San Diego, CA), with fitting constrained to a slope of 1 and a baseline of 0.
 To understand how toxin mixtures may act at the Na channel receptor via which PSTs exert their neurotoxicity.To test if the presence of weaker toxins dilutes stronger toxins
 The strong dominance of a mixture by the most potent toxins has implications for measurement of toxic test samples and for standards that may contain low levels of highly potent bioactive impurities.

2018 Aerial survey data of southern right whales (Eubalaena australis) off southern Australia

These aerial survey data of southern right whales (Eubalaena australis) off southern Australia were collected in August 2018. Such annual flights in winter/spring between Cape Leeuwin (Western Australia) and Ceduna (South Australia) have now been conducted over a 26-year period 1993-2018. These surveys have provided evidence of a population trend of around 6% per year, and a current (at 2014) population size of approximately 2300 of what has been regarded as the 'western' Australian right whale subpopulation. With estimated population size in the low thousands, it is presumed to be still well below carrying capacity. No trend information is available for the 'eastern' subpopulation of animals occurring around the remainder of the southern Australian Coast, to at least as far as Sydney, New South Wales and the populations size is relatively small, probably in the low hundreds. A lower than  expected 'western' count in 2015 gives weak evidence that the growth rate may be starting to show signs of  slowing, though an exponential increase remains the best description of the data. If the low 2015 count is anomalous, future counts may be expected to show an exponential increase, but if it is not, modelling growth as other than simple exponential may be useful to explore in future.

Beach Face and Berm Morphodynamics Fronting a Coastal Lagoon

This study documents two different modes of berm development: (1) vertical growth at spring tides or following significant beach cut due to substantial swash overtopping, and (2) horizontal progradation at neap tides through the formation of a proto-berm located lower and further seaward of the principal berm. Concurrent high-frequency measurements of bed elevation and the associated wave runup distribution reveal the details of each of these berm growth modes. In mode 1 sediment is eroded from the inner surf and lower swash zone where swash interactions are prevalent. The net transport of this sediment is landward only, resulting in accretion onto the upper beach face and over the berm crest. The final outcome is a steepening of the beach face gradient, a change in the profile shape towards concave and rapid vertical and horizontal growth of the berm. In mode 2 sediment is eroded from the lower two-thirds of the active swash zone during the rising tide and is transported both landward and seaward. On the falling tide sediment is eroded from the inner surf and transported landward to backfill the zone eroded on the rising tide. The net result is relatively slow steepening of the beach face, a change of the profile shape towards convex, and horizontal progradation through the formation of a neap berm. The primary factor determining which mode of berm growth occurs is the presence or absence of swash overtopping at the time of sediment accumulation on the beach face. This depends on the current phase of the spring-neap tide cycle, the wave runup height (and indirectly offshore wave conditions) and the height of the pre-existing berm. A conceptual model for berm morphodynamics is presented, based on sediment transport shape functions measured during the two modes of berm growth.

NESP TWQ Project 2.3.1 - Benthic light as ecologically validated GBR wide indicator for water quality: drivers, thresholds and cumulative risks, 2016-2018 (AIMS)

The project will develop a water quality indicator based on benthic irradiance (the amount of light penetrating to the seafloor). Using experiments and field data we will develop irradiance thresholds for measures of ecosystem health, and develop prototype guideline values. The project will develop a new remote sensing algorithm of benthic irradiance, validated against open-water irradiance data. The project will quantify benthic irradiance throughout the GBR, near-daily over 14 years, and assess region-specific drivers of trends including river discharges. The indicator can directly feed into Reef Plan report cards, irradiance as a limiting factor, and about cumulative risks in the context of coral bleaching.

NESP TWQ Project 1.3 - A validation of coral geochemical records to reconstruct suspended sediment loads to the Great Barrier Reef lagoon, 2015-2016 (JCU)

While coral geochemistry records are widely cited as evidence for increased suspended sediment loads delivered to the Great Barrier Reef since the 1850s, there has been little replication or quantification of the records. Indeed, most records are based on cores collected prior to the year 2000 when limited catchment monitoring data existed to ‘validate’ the interpretations that certain trace element ratios provided proxies of annual sediment loadings. This project will analyse the geochemistry of coral cores collected in 2012 from sites in the central GBR and compare the ratios to measured sediment and particulate nutrient loads from the Burdekin River.

Diets of four shrimp species in eelgrass habitats, Western Port Bay, Victoria

This study examined stomach contents of shrimp sampled in the beam trawls in Western Port Bay from July 1977 to January 1980 (see parent record 'The ecology and trophic role of caridean shrimps in the eelgrass community of Western Port, Victoria', File identifier: 268431c0-f18e-11dc-aaae-00188b4c0af8). An evaluation was made of summer and winter diets of Macrobrachium.intermedium, Pontophilus intermedius and Hippolyte caradina. Chlorotocella leptorhyncus was not present in the summer samples, so only the winter diet of this species was determined. Food items in the stomach were identified and the size of intact specimens was measured. All items were counted and assigned to a taxonomic category at the lowest possible level. The relative volume of individual prey items and taxonomic groups was also estimated.
During summer, M.intermediaum fed on a mix of animals (small crustaceans, gastropods, and polychaetes) and plant matter, and during winter, the diet was mostly plant matter. Polychaetes were the abundant prey items in the stomachs of P.intermedius, representing close to 70% of the diet in summer and winter. Almost 70% of the overall volume of food consumed by H.caradina was plant matter with small crustaceans, gastropods and insects making up the remaining proportion of the food consumed. The amount of plant matter in the diet increased in the winter months. C.leptorhyncus was found to ingest approximately equal volumes of animal and planter material with polychaetes the most abundant animal prey. The plant matter found in all samples was mostly dead eelgrass tissue.

RAN CTD Profile Data - HMAS SHEPPARTON ProjectID: HI554SHE_M From: 2014-07-10 To: 2014-08-04

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 163 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI554SHE_M from HMAS SHEPPARTON.
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.

A tale of two reef systems: Local conditions, disturbances, coral life histories, and the climate catastrophe

Long-term changes in benthic communities and habitat conditions were studied at Rowley Shoals and Scott reef systems.
This collection includes data from surveys from the Long-Term Monitoring (LTM) programs at Scott Reef (from 1994) and Rowley shoals (from 1995) which are conducted usually every 1&ndash;2 years (&lt;4 years), in addition to heat stress habitat surveys in 2016.
Each LTM location contains three replicate sites, separated by 300&thinsp;m, consisting of five permanently marked 50-m transects, laid end to end and separated by 10 m. Images of the benthic community were captured at a distance of 30&ndash;50&thinsp;cm from the substratum, along 1m intervals. Each image was analysed by identifying the benthic group under each of five fixed points to the lowest taxonomic resolution (Jonker et al., 2008).
Additional monitoring locations were established in 2016 to assess the effects of predicted heat stress. Sites were established at the reef crest and lagoon at each location, consisting of six permanently marked 20-m transects, laid end to end and separated by 10 m. Surveys were conducted before (January) and during (April) the time of peak heat stress in 2016, and in October 2016 at Scott Reef and October 2017 at Rowley Shoals to quantify associated reductions in coral cover. 
Spatial and temporal variation in reef slope communities were compared using multivariate analyses, as well as analysis of environmental parameters. For full details see Gilmour et al., (2022).
