Sea cage aquaculture, Hinchinbrook Channel, North Queensland

Sediment data was collected for analyses of potential environmental impacts from a sea cage barramundi (Lates calcarifer) aquaculture farm.Analyses were conducted on solid wastes for N, P, OC, trace elements (e.g. Zn) and other components included in feeds. Sediment oxygen consumption rates (respiration) were used an indicator of OC input, and ammonium, phosphate, and nitrite + nitrate flux rates (umol/m2/day) as indicators of organic N and P input and breakdown (mineralisation). The N:P molar ratio of fluxes and the Redfield ratio (C:N:Si:P) were calculated.Sediments were also analysed for grain size, OC, TC, TN, TP, Zn, Li, redox and pH. Sediment Grain size (um) categories: fine silt, clay, quartz sand and coarse material (leaves, wood, rocks and shell). Sediment C, N and Total Organic C (TOC) percentages were measured. C:N ratios were calculated for the different sites (cage, north, reference and south). The ratios of Zn:Li and P:Li in sediments were also calculatedThe reference location, a transect through the cages and sites at adjacent mudbanks were sampled for sediment Redox potential (Eh), pH, temperature, and surface dissolved oxygen, temperature and salinity. Leaves from Rhizophora stylosa (the dominant mangrove species) were analysed for 15N along the entire length of Conn Creek and at the reference location.Water column sampling: Transects comprised single water samples taken subsurface at each station throughout Conn Creek. Variables measured were: dissolved nitrogen (ammonium, nitrate and TDN), dissolved phosphorus, particulate nutrients, suspended solids and dissolved silica.Other variables were: tides (spring and neap); seasons (wet/summer and dry/winter); and place in the water column (near surface and near bottom).Chlorophyll a and bacterial abundances were measured and a chl:bacteria ratio calculated (as an indicator of organic pollution).Water column photosynthetic and community respiration rates were estimated at sites near cages and remote from cages.
 To estimate the area of influence of the farm, the carrying capacity of the environment in the area, and the fate of uneaten feed and other aquaculture wastes.

WAMSI 2 - Kimberley Node - Project 2.1.1 - Human use patterns and impacts in the coastal waters of the western Kimberley

Aerial surveys were undertaken throughout the Kimberley for a 12-month period from November 2012 – October 2013. The three main survey areas incorporated into the sampling design were Camden Sound, Dampier Peninsula and 80 Mile Beach. Also Eastern Kimberley for one survey.
In total, 41 aerial surveys were completed throughout the Kimberley from November 2012 – October 2013.  During this time period, several thousand photographic images were taken and examined and nearly 4,000 images showed evidence of human use. These images were used to classify and catalogue shore and boat-based recreational activity.
Data outputs are separated into a) processed data (Geodatabase of point data - Kimberley_Aerial_ASA and raster layers of density for the 2 survey areas - 80M_DensityOutputs and DP_DensityOutputs) b) raw data (folders containing .csv, shapefiles and .jpegs from each survey) and c) survey information (information about each survey e.g. date, time, pilot, observers, start, finish location etc.)

Surveys of fish-habitat associations using Baited Remote Underwater Video Stations (BRUVS (TM)) offshore from Port Hedland, Western Australia

In July 2012, baited remote underwater video stations (BRUVS (TM)) were deployed in the vicinity of Port Hedland, in two areas parallel to the coast (inshore and offshore) on either side of the shipping channel and some dredge spoil grounds, in depths of 4.6 to 24 metres.The survey design specified the deployment of 230 BRUVS (TM) at random within grids of the two study areas, at a spacing not less than 450 metres apart, to minimise the likelihood of individuals moving between stations and being double-counted. Of the 230 BRUVS (TM) deployed during the field campaign, 221 produced imagery of sufficient quality for analysis.Commencing immediately after reaching the seafloor, 60 minutes of bottom-time was analysed for all video recordings, regardless of whether video extended longer. Data was recorded using a purpose built interface and included identification to species level and life stage (adult or juvenile) of all vertebrates, relative abundance (MaxN ; maximum number visible at any single point on the tape), time of arrival and the time elapsed before MaxN and feeding occurs. Depth and GPS position of each deployment, estimates of water clarity and the timing of ancillary events such as feeding activity and loss of bait bag were also recorded.The habitat at each station was classified by reviewing an image of the seafloor from each of the BRUVS (TM) sampling stations. To provide quantitative estimates of habitats, the percentage cover (to the nearest 10%) was then determined for six categories of (abiotic) substratum, summed to 100%, and for 12 categories of (biotic) epibenthos, also summed to 100%.
 This study was undertaken to provide baseline estimates of fish diversity and relative abundance in direct relation to habitat and depth within inshore and offshore areas in the vicinity of Port Hedland, where a large expansion of port facilities will be accompanied by dredging and relocation of dredge spoil on adjacent seabeds in the local region.

Physical Oceanography of Karmt Shoals, Timor Sea (2004)

Two oceanographic moorings (Karmt 50 and Karmt 100) were set in 50 and 100m water depth near the Karmt Shoals in the Oceanic Shoals Bioregion of the Timor Sea in 2004. The moorings were set in January 2004, recovered and redeployed in April 2004, and finally recovered in December 2004.A current meter and 4 temperature and pressure recorders were attached to each mooring for both deployments.
 This study was undertaken to investigate the distribution of shelf edge upwelling phenomena, a potentially significant attribute of the Oceanic Shoals bioregion.
 This study was a component of the project "Biodiversity and the factors controlling it, for selected habitats in the Timor Sea region", which seeks to integrate data from biodiversity surveys, chemistry, oceanography and geology to understand the processes that sustain the biota of the region.

National Intertidal-Subtidal Benthic NISB Habitat Distribution Map Series

The National ECM Key Habitat Distribution Map Series were derived from the NISB
Habitat Map created by the University of Tasmania for a partnership between the
Department of Climate Change and the National Land and Water Resources Audit. It
supports the DCC/Audit partnership by providing a nationally consistent set of the
available mapping data that show the distribution of habitats that occur between the
approximate position of the highest astronomical tide mark (HAT) and the location of
the outer limit of the photic benthic zone (approximately at the 50-70 m depth contour).
This area is broadly equivalent to the “inner” and “mid-shelf” regions identified by
Geoscience Australia. The resulting map data set forms a core component of the ECM
National Habitat Map Series.
The habitat classes include: coral reef, rock dominated habitat, sediment dominated
habitat, mangroves, saltmarsh, seagrass, macroalgae and filter feeders (e.g. sponges), as
defined in the NISB Habitat Classification Scheme. The scheme is designed to support
the development of marine ‘ecoregions’ or bioregional subregions. Details of the
scheme and the process of its development are available in National Intertidal/Subtidal
Benthic (NISB) Habitat Classification Scheme Version 1 (Mount, Bricher and Newton,
2007).
The 10 km and 50 km tiles distribution maps that form the National ECM Key Habitat
Distribution Map Series were derived from the NISB Habitat Map in order to produce
maps at resolutions that are easy to interpret at state and national extents. For each state,
two layers were produced, one with 10 km and one with 50 km tiles. In each layer, new
fields were created listing the presence, absence, unknown distribution or nonapplicability
of the Habitats of Interest (HOI). The HOI are rock substrate (Class 1.2),
unconsolidated substrates (Class 2.0), coral habitat (classes 1.1 and 1.2.2.3), sediment
dominated habitats (Class 2.0.1), seagrass dominated habitats (Classes 1.2.2.4 and
2.0.2.1), mangrove dominated habitats (Class 2.0.2.2) and saltmarsh dominated habitats
(Class 2.0.2.3).
There are technical geographic and cartographic issues that arise when comparing
mapped data sets of multiple scales, as is the case for this compiled and derived data
set. The two derived information products were generated to provide a simplified
spatial representation of the broad distribution patterns of each of the key habitats
National ECM Habitat Map Series User Guide_v7.doc 30/04/2008 Page 32 of 156 
across large areas. These derived products are designed to enable the visualisation of
the habitat distributions at the regional and national extents. It is extremely important
to note that they are definitely NOT able to be used to calculate areas of habitat
types.

IMOS - Ocean Radar - Phased array HF ocean radar system (WERA)

Coastal ocean surface radar is a land-based technique which uses scattering from the rough sea surface to obtain echoes which are Doppler shifted by the dynamics of the sea.  It has been shown (Crombie, 1955) that the scatter is predominantly a Bragg interaction between the radio wave and the sea surface gravity wave that is propagating in the same direction and with half the wavelength of the radio wave.  This Bragg interaction gives two strong first-order lines in the echo spectrum; one from the resonant gravity wave moving radially away from the station, and one from the resonant gravity wave moving towards the station.
Phased array systems determine the azimuthal angle between the station and a point on the sea surface by forming a narrow beam; the range to the point is set by the propagation delay for the electromagnetic wave.  For the phased array systems, the two radar stations each operate for alternating periods of 5 minutes on and 5 minutes off, and out of phase, so that they can use the same frequency without interfering with each other.  During each 5 minute of operation the radar measures the component of the surface current at each point projected onto the radial from the station to the point.  
At the end of 10 minutes, the radial components of surface currents can be combined from the two stations to find the vector at each position on the grid.  While surface currents are generally the data of most interest, the phased array systems can also produce significant wave heights and wind directions at each grid point and a calculation of the full directional wave spectrum at ranges of up to about half the maximum range (which is 150 km).
WERA HF ocean radar systems are used in the Capricorn Bunker Group (Tannum Sands and Lady Elliot Island), Queensland, at South Australian Gulf (Cape Spencer and Cape Wiles), South Australia, for Rottnest Shelf (Fremantle and Guilderton), Western Australia, and at Coffs Harbour (Red Rock and North Nambucca), New South Wales.

Spatial variation of the intertidal sediments and macrozoo-benthic assemblages along Eighty Mile Beach, North-western Australia

The extensive intertidal flats along Eighty-mile Beach in North-western Australia appear to be monotonous and homogeneous and seem ideally suited to study tidal zonation in macrozoo-benthic communities and their possible correlates with characteristics of the sediment. In October 1999, we sampled benthic invertebrates and sediments at a total of 895 sampling stations distributed over six different locations, each location separated by 15 km of unsampled foreshore along Eighty-mile Beach. To test for the presence or absence of patterns of tidal zonation (distinct height-related zones of specific sediment grain sizes or zoobenthic taxonomic groups) or patchiness (distinct patches of specific sediment grain sizes or zoobenthic taxonomic groups not related to tidal height) each location was divided into three along-shore sections and each section (transect) was examined at two or three tidal heights. Zonation was observed for sediment grain sizes. Sediments were coarser at the highest intertidal level and finer towards the low water line. Benthic assemblages also differed among tidal heights, but in terms of species-composition the differences were not consistent among the locations. Each location supported a unique collection of benthic invertebrates. Therefore the hypothesis of the presence of distinct zones of specific species or zoobenthic taxonomic groups was rejected; the presence of benthic patches was confirmed. The distribution of sediments and the composition of benthic assemblages were surprisingly poorly correlated compared to those reported in 12 previous quantitative studies around the world. One possible explanation might be that super-cyclone Vance, which hit the study-area only six months before this study, contributed to this poor correlation. Alternatively, the poor correlation may indicate that biotic interactions are more important than the assumed abiotic structuring.

Pearl Oyster Sustainability

The pearl fishery in WA has historically been based on the species Pinctada maxima, which produces the prized large South Sea pearl. Wild shell is collected according to quota and the oysters are then seeded and tended on longlines at farms in ocean bays in tropical waters. Oyster hatcheries are now producing spat to supplement wild shell capture, but the industry relies on wild stocks. The current quota for wild shell is
Project and activity description:
The project will:
* maintain catch and effort database monitoring, policy advice and liaison, annual status reports and stock assessment, population model development and publications relevant for the wild pearl oyster fishery;
* initiate a piggyback spat and length frequency monitoring program on industry vessels, as a measure of recruitment of wild pearl oysters. The FRDC project is Predicting and Assessing Recruitment Variation - a critical factor for the management of the Pinctada maxima fishery in Western Australia; and
* provide assistance to industry and management decision makers on setting the quota for the catch of wild P. maxima shell.

Assessment of three species of copepods as live feeds in aquaculture

Stock cultures of the copepods Bestiolina similis, Parvocalanus crassirostris and Acartia sinjiensis were maintained at the Australian Institute of Marine Science in a temperature controlled room (27 &plusmn; 0.5&deg;C) in three 20 litre culture containers with gentle aeration and a 12:12 light:dark cycle. Cultures were fed to excess with mixtures of the microalgae Isochrysis sp., Tetraselmis chuii, Rhodomonas sp. and Heterocapsa niei. Cultures were monitored daily and nauplii were removed and used to seed fresh cultures.
For each copepod species, samples of 200-300 eggs and nauplii were placed in each of eight 2.3 litre polycarbonate bottles and fed to excess with the same micro-algal species used to maintain stock cultures and the bottles were placed on a plankton wheel at 0.5 rpm. Three experiments were conducted for each species by taking sequential sets of eggs and nauplii from the same cultures.
Bottles were sampled at least daily by pouring off enough volume to yield &gt;30 copepods and the media returned to the bottle. Time (not for eggs), length and width (&micro;m) of the developmental stages (egg, nauplii I-VI, copepodite I-V, adult) of the three copepod species were recorded. Gender was assigned to CV and adult stages.
Female copepods were isolated from each stock culture and acclimated to uni-algal diets of either Chaetoceros muelleri, Dunaliella sp., Rhodomonas sp., Heterocapsa niei, Tetraselmis chuii, Isochrysis aff. galbana or Pavlova salina for 24 hours prior to egg production experiments. Egg production was measured for each combination of copepod species and uni-algal diet by placing five adult females in each of five 500 ml flasks containing uni-algal cultures and placing the flasks on a plankton wheel at 0.5 rpm. After 24 hours the contents were condensed and preserved for later counts of nauplii and eggs.
To investigate the escape responses of each of the three copepod species, simulated predation experiments were conducted. Ten sets of animals of each size
class and species, and the percentage of copepods removed by the siphon were recorded.
Lipid composition (%), content (mg/g dry mass), and fatty acid compsition (%) were examined, and lipid ratios were calculated for each species. Selected samples were also examined for the sterol profile in each species.
This research was undertaken to compare two small calanoid copepods, Bestiolina similis and Parvocalanus crassirostris, to the larger Acartia sinjiensis, for their aquaculture potential as live feeds in terms of size, productivity, availability and nutritional composition.
To assess two species of copepods for their potential as live feeds in aquaculture.
Acartia sinjiensis is the species of the copepod genus most commonly cultured to provide larval diets for tropical snappers and groupers.

Heron Island Sensor Relay Pole 4 (RP4)

A series of six 6m steel poles have been installed in the lagoon of Heron Island as part of the sensor network deployment at Heron Island. The poles serve two purposes; their primary purpose is to form the backbone of a wireless network that covers the entire lagoon system and secondly they themselves support a range of sensors mounted onto the pole or leading away from the pole. One pole (RP5) also supports a Vaisala WXT520 weather station.This record is for Sensor Relay Pole 4. The pole is solar powered and routes data from the Sensor Floats and other Sensor Relay Poles back to the Base Station located on Heron Island. The system uses the Campbell Scientific CR1000 loggers and RF411 Spread-Spectrum radios to process and route the data. The poles also can support a range of sensors, this pole also has a simple bottom mounted thermistor using the MEA thermistors.The unit will be serviced every six months and will be used in the future for attaching new sets of sensors.
 The pole works primarily as a network repeater, it collects data from other poles and the Sensor Floats and routes it back to the Base Station either directly or via another pole. The poles are spaced approximately every two kilometers with the exception of those closest to the island, the base station on the island is on a 19M tower and so a greater range was found for the first set of poles.Each pole therefore provides a wireless data network in a two kilometer radius, the combination of the six poles provides coverage for the entire lagoon. The height of the base station gives around a five kilometre range around the island itself.The poles are 6M in height constructed from galvanized steel with a solar powered instrument top consisting of a battery unit powered from the solar panels, Campbell CR1000 logger and Campbell RF411 radio. The logger can support a range of interfaces and is suitable for connection to a range of instruments.The initial instrumentation is just a single base mounted MEA thermistor, the intention is to add more instruments as time and opportunity allow.
