Variation in tissue thickness in massive Porites corals from the Great Barrier Reef

Measurements were obtained from existing samples of Porites colonies held in the collections at the Australian Institute of Marine Science, and from small colonies collected from the Great Barrier Reef. 
Tissue depth was measured on 19 massive Porites colonies collected the Northern Coral Sea and the Great Barrier Reef (GBR), between November 1987 and December 1990. Colonies were collected from Ashmore Reef, Lagoon Reef, Eel Reef, Portland Roads, Rocky Island, Night Island, Reef No. 13-055 and Reef No. 13-050, Stephens Island and Bedarra Island, Myrmidon Reef, Rib Reef and Pandora Reef, Davies Reef, Shaw Island, Reef No. 20-200, Credlin Reef, Reef No. 21-141 and Middle Percy Island.
Tissue depth was also measured on coral cores collected from massive Porites colonies from 30 reefs in Torres Strait and the GBR between August 1983 and May 1988. Cores were collected from Darnley Island, Pascoe River, Burkitt Island, Boulder Reef, Escape Reef, Snapper Island, Low Islets, Normanby Reef, Kurrimine Beach, Kumboola Island, Bedarra Island, Coombe Island, Brooke Island, Britomart Reef, Rib Reef, Yankee Reef, Great Palm Island, Pandora Reef, Wheeler Reef, Acheron Island, Magnetic Island, Hooke Island, North Molle Island, South Molle Island, Lupton Island, Scawfell Island, Sanctuary Cay, Abraham Reef, Halfway Island, Masthead Island.
Colonies were selected from environments towards the rear of the windward reef flat or on sheltered parts of fringing reefs in the lee of the islands at depths between 3 and 5 m relative to mean low water spring tide levels. The species of coral colonies analysed were: P. lutea, P. lobata, P. australensis, P. solida and P. mayeri, P. murrayensis, P. densa and P. stephensoni. A total of 284 corals were analysed for tissue thickness.

Rock sample data collected on the Denman Marine Voyage of the RSV Nuyina, 2025

During voyage 3 of the RSV Nuyina during the 2025/2025 season to the region offshore the Denman glacier, rock samples were recovered to understand i) the continental geology of the Bruce Rise, ii) the onshore geology of the Denman region (from ice-rafted debris samples), and iii) the timing and mechanism driving formation of seamounts (extinct seafloor volcanoes).
The voyage was colloquially known as the "Denman Marine Voyage", as it operated in the vicinity of the Denman Glacier.
Rock samples were recovered from dredge (DXX), beam trawl (BT-Y), kasten core (KCXX), and multicore (MCXX) deployments during the voyage (where XX is the sequential deployment number, and Y is the sequential deployment letter).
Folders in this dataset are named by their deployment type and number/letter. Within each folder there are i) descriptions of each rock/sediment sample, and ii) photographs of each sample. Descriptions are preliminary and were undertaken on board look at the hand samples, and sawn hand samples using a hand lens. 
Dredged rocks were described and photographed individually. For the case of sawn rock saws, photographs of the cut surfaces both dry and wet were taken. Beam trawled rocks were sorted into groupings and a description and photographed in these groups. Samples from kasten cores and multicores were described individually. Photographs of the kasten core and multicore rocks sometimes contain multiple different samples per photograph.

Beagle Gulf Mooring (NRSBEG) Automated Marine Weather And Oceanographic Station

The Beagle Gulf Surface Buoy was deployed from May 2015 to July, 2017. The nearby Darwin mooring (NRSDAR) provides ongoing observations in this region. 
Data recorded: Air Pressure, Air Temperature, Current, Depth, Dissolved Oxygen, Fluorescence, Humidity, Light, Rain, Salinity, Turbidity, Water Temperature, Wave and Wind Speed and Direction.
The Beagle Gulf mooring extended seaward oceanographic observations from Darwin Harbour and complemented the National Reference Station located at Channel Marker Buoy#5. The mooring was upgraded to near real time in September 2014. Channel marker number 5 was removed in February 2015, resulting in the mooring being moved to Channel marker 1. For full instrumentation specifications see the informaition recorded for each deployment at link https://www.aims.gov.au/imosmoorings/
The marine observing systems deliver the information needed to support the development and operational management of ports and harbours. Most ports and harbours are multi-use regions supporting industry and recreational activities, and observing systems play an important role in both port operations, and in generating understanding of processes that impact the sustainable use and development of these areas (e.g. sediment transport, water quality). Water current profiles and wave measurements directly assist shipping operations and feed into a model that seeks to evaluate impacts on the health of the harbour.
The NRS Darwin mooring (IMOS platform code: NRSDAR), is one of 9 IMOS ANMN National Reference Stations (NRS) designed to monitor oceanographic phenomena in Australian coastal ocean waters. The NRSDAR buoy is deployed at Latitude: -12.3382, Longitude: 130.6952.
The IMOS national reference stations will extend the number of long term time series observations in Australian coastal waters in terms of variables recorded both in their temporal distribution and geographical extent. It will also provide for biological, physical and chemical sampling and for &#39;ground truth&#39; of remotely sensed observations.
IMOS is an Australian Government initiative established under the National Collaborative Research Infrastructure Strategy and the Super Science Initiative and supported by Queensland and Western Australian State Governments.

IMOS - National Mooring Network - Passive Acoustic Observatory at Perth Canyon, WA (PAPCA)

The Perth Canyon Passive Acoustic Observatory consists of two to four moorings fitted with hydrophones set on the seabed at 400-490 m depth that record noise in the ocean. This system can be used to monitor whale and fish migrations, seismic activity and other natural and man-made noise sources. If four moorings are set they are configured with a mooring at each apex of an approximate equilateral triangle of 5 km side with the fourth mooring in the triangle centre. Temperature loggers are set on each mooring at the seabed.
Each logger records at a sampling rate of 6 kHz for between 3-8 min of every 15 min. If four loggers are set a 22 kHz recording is also made once a day to allow accurate synchronisation of the instrument clocks. This is required for locating the source of a sound based on its time of arrival at each hydrophone in the array. A 7 kHz pinger set on the central mooring pings for 35 minutes at a 20 s interval once per day to overlap the 22 kHz sample.
Raw data from each logger is in the form of mixed binary/text files comprised of: 
1) text header and footer containing recording start and end date/time, quality control and sampling configuration; and 
2) sea noise data of 16 bit unsigned integer, binary values (IEEE, little endian). 
Instruments are calibrated for system gain with white noise of known level input with the hydrophone in series, before and after deployments. System calibrations are made over 2 Hz to the Nyquist frequency. The instrument clock drift is checked against GPS transmitted UTC time before and after deployment.
The raw data can be obtained on portable disk from the Australian Ocean Data Network (AODN).
The Centre for Marine Science and Technology (CMST) at Curtin University has developed Matlab software to process and analyse these data.
This observatory was decommissioned in October 2017.

Population dynamics of the infaunal bivalve, Soletellina alba

The population dynamics of the infaunal bivalve Soletellina alba were investigated at three sites situated in close proximity to the mouth of the Hopkins River estuary from 1997 to 1999. The distribution and abundance of juvenile and adult S.alba was very variable across all dates, sites and channel elevations (i.e. water depths). An experimental test comparing the recruitment of juveniles at different channel elevations and in sediments of varying particle size was conducted  during 1999. The results of these tests showed that recruitment was greatest at the shallowest channel elevation and there was little evidence that sediment particle size influenced recruitment. In contrast to 1999, recruitment during 1997 or 1998 was very low.
Growth rates were monitored using tagged individuals held in caged and uncaged plots, which revealed that growth was highly variable among individuals, but not between sites. These tests also revealed that growth was negligible during the colder, winter months, and that the fastest growing individuals were capable of growing 0.2 mm/day.
Salinity tolerance experiments showed that bivalves exposed to low salinities (&lt; 6 ppt), exhibited poorer condition and took longer to re-burrow into sediments than those exposed to greater salinities (&gt; 14 ppt), while death of bivalves exposed to salinities &lt; 1 ppt occurred after 8 days of exposure. These tests provide evidence that low salinities are probably the principal cause of mass mortalities that are observed during winter flooding, although the interaction between salinity, temperature and turbidity also deserve consideration in the future. 
It is hypothesised that the survival of very young juveniles (between 0.5mm and 1mm shell length) and rapid growth rates are important features of the life history of S.alba that explain its successful persistence within the Hopkins River estuary. It is highly likely that this species is capable of completing its entire life cycle within the estuary. The absence of other nearby populations, and periods of mouth closure, are likely to greatly limit the potential contribution made by larvae entering from the surrounding marine environment. This study has added to our knowledge of how an infaunal bivalve copes with life in the intermittently closing estuaries that typify semi-arid coastlines in the Southern Hemisphere.

Norfolk Island Nearshore and Coastal Habitat Mapping

Ocean Infinity (Australia) Pty Ltd (formerly iXblue Pty Ltd), in partnership with Deakin University’s Marine Mapping Group, University of Wollongong, Tellus4D Geoimaging, University of Newcastle, University of New South Wales, University of Tasmania, and Geoscience Australia, undertook a combined aerial and hydrographic survey as part of the Norfolk Island Nearshore and Coastal Habitat Mapping project under Parks Australia Grant Activity ID 4-FISKTDM.
The work aimed to establish a detailed baseline of Norfolk Island’s nearshore coastal and shelf environments to inform management, conservation, and research. From 21 to 24 July 2021, 109 km² of the Norfolk Shelf was mapped using high-resolution multibeam sonar, along with two sub-bottom profiles. These were supplemented by 44 Baited Remote Underwater Video (BRUV) deployments in the northeast and south of the island to assess fish assemblages and provide ground truthing data for interpretation of seabed nature.
In November 2021, a separate coastal survey using high-resolution drone photogrammetry captured geomorphic and habitat information at seven coastal sites: Captain Cook Lookout, Anson Bay, Puppy’s Point, Headstone Point, Slaughter Bay and Bombora Beach, and Cemetery and Emily Bay. These locations span a variety of morphologies, from exposed basaltic shore platforms and dramatic cliffs to offshore stacks and pockets of rocky beach.
The data collected by the project provides a detailed view of the marine and coastal geomorphology of Norfolk Island. The data provides an initial condition assessment of key areas to inform park management, habitat protection, and future targeted studies such as further bathymetric mapping in sensitive areas and expanded ground-truthing of seabed habitats.

Variation in assemblages of Lutjanidae and Lethrinidae among mid-continental shelf reefs in the central Great Barrier Reef

Surveys of fish in the families Lutjanidae and Lethrinidae were carried out on three midshelf reefs (Rib Reef, John Brewer Reef and Lodestone Reef) in the central Great Barrier Reef at approximately 2 monthly intervals between September 1992 and July 1993. The back reef habitat (NW aspect, leeward slopes) of each reef was surveyed and the areas censused on each of the reefs were as similar as possible in terms of their physical characteristics.Six replicate non-overlapping visual censuses of the lutjanid and lethrinid assemblages in the shallow back reef zone (0-10 m) were undertaken at each reef during each of the 6 sampling periods. Dives were conducted haphazardly; transects were not fixed, and no two censuses within any sampling period covered exactly the same census area. Diel differences in catches, large-scale differences among reefs and differences between depths within reefs through time were investigated using fish traps. During each of the 6 sampling periods, 12 traps were set by day and 12 at night in each of two depth zones (shallow: 12-18 m, and deep: 30-40 m) at each reef. Traps were deployed randomly in each depth zone.For day sampling, traps were set in the morning (0600-0830 h) and retrieved in the evening (1630-1830 h), resulting in a soak time of between 9 and 11 hours. For night sampling, traps were set in the evening (1700-1830 h) and retrieved the following morning (0530-0800 h), resulting in a soak time of between 12 and 14 hours. The catch of each trap was identified to species and measured to the nearest millimetre.
 Visual census and fish traps were used to investigate assemblages of the Lutjanidae and Lethrinidae from surface waters to the base of the back reef among three replicate reefs at one continental-shelf locality (mid-shelf) in the central Great Barrier Reef to determine whether previously observed spatial patterns in species abundance were persistent through time.

The population dynamics of the gastropod Lepsiella vinosa on the West Head rocky shore in Victoria

This study surveyed the size distribution of Lepsiella vinosa at 3 sites on the rocky shore at West Head, Victoria. Monthly or bi-monthly searchers were conducted from June 1975 to August 1978 during spring low tide. Every individual L.vinosa found at the 3 sites was measured to the nearest 0.01cm with vernier calipers. To determine recruitment of L.vinosa to the shore, individuals were arbitrarily designated as juveniles (&lt; 0.8 cm) or adult (&gt; 0.8 cm). The type of microhabitat where each individual was found was recorded at Sites 1 and 2 for the searchers conducted in spring (November 1977), summer (January 1978), autumn (April 1978), and winter (August 1978). 
There were larger individuals of L.vinosa at higher intertidal levels (Site 1) compared to the mid- and lower sites (Sites 2 and 3). The recruitment of juveniles could not be determined from the size frequency distribution at any of the sites. There was more L.vinosa than expected in the rock pool habitats compared to the bare rock in all seasons except for winter at Site 2. There was high variability in abundance in the Lichinia habitat between all seasons and sites.
