A description of the reproductive cycle of the gastropod Lepsiella vinosa on the West Head rocky shore in Victoria

This study used histological methods to describe the reproductive cycle of Lepsiella vinosa. L.vinosa was collected from the West Head rocky shore on 12 occasions between April 1975 and March 1976. Individual shell lengths were measured and the soft tissue of the animals removed to determine the sex. Four to six animals of each sex were used for histological examination by excising a 5 mm section of the visceral coil from each animal. Ovarian sections at 100 micron intervals were examined under a compound binocular microscope and the numbers of immature and mature oocytes were counted. The area of the testis in the visceral coil was used as an estimate of the maturity of males.
There were 177 males and 169 females collected and the females (average 0.86 ± 0.09 cm) were generally larger than males (average 0.82 ± 0.09 cm). The sex ratio was female bias throughout the year. There were significantly more immature oocytes present in the ovary throughout the year with a peak in May and June. The testis occupied a proportionally larger cross-sectional area of the visceral coil in summer and early autumn and then decreased in size to a minimum in August. This testis size correlated with observations of copulating pairs of L.vinosa during autumn and winter at West Head.

Assessing the effects of changes in Great Barrier Reef Marine Park Zoning plans on southern mid-shelf shoals (MTSRF Project 4.8.2)

Surveys were undertaken in February/March 2007 (Autumn), August/September 2007 (Spring) and October 2009 (Spring) on two pairs of discrete deepwater shoals in the mid-shelf section of the southern Great Barrier Reef. The objective was to find pairs of shoals that were matched in terms of depth, habitat, areal extent, cross shelf position and latitude. Within each pair, one shoal was to be from a 'green zone' (closed to all fishing) and the other from a 'blue zone' (open to fishing), based on the rezoning of the Great Barrier Reef Marine Park, carried out in 2004. The pairs of reefs chosen were: East Warregos (green) and West Warregos (blue); Barcoo Bank (green) and Karamea Bank (blue). The bathymetry of each shoal was surveyed in detail by multibeam acoustic swathe mapping prior to sampling of fish and benthic habitat. A lightweight towed video system developed by AIMS was used to survey seabed habitats on and around the four shoal sites over the first two trips.Baited Remote Underwater Video Stations (BRUVS (TM)) were used to sample the fish communities on each shoal on all three cruises.
 This study was undertaken to describe the fish fauna in relation to habitat and spatial and temporal variables on selected deep shoals of the southern region of the Great Barrier Reef Marine Park.
 This is one component in a series of surveys conducted as part of this MTSRF project, see also separate metadata records on:Reef base shoals (Capricorn-Bunker, Pompey and Swains Groups) Shoals off Cardwell Shoals off Cairns Magnetic Shoals (Townsville)

Enhanced Vegetation Index (EVI) - MODIS, LPDAAC MOD13Q1 mosaic despiked, Australia coverage

EVI time series over some land cover types sometimes contain spikes and sharp drops that do not represent biophysical changes on the Earth surfaces. These spikes need to be removed prior to further analysis. This dataset uses an algorithm described in the technical report (http://www.ga.gov.au/scientific-topics/earth-obs/landcover) to remove spikes/sharp drops from the EVI dataset. The dataset has also been transposed from individual EVI timeslices into a datacube that can be used for multitemporal analysis.

Spencer Gulf fisheries, Marine Scalefish Fishery Catch and Effort Logbook Data (includes Miscellaneous Fisheries)

The Marine Scale Fishery has traditionally been one in which fishing effort shifts temporarily and spatially between species, depending on their relative abundance and value. SARDI research projects have concentrated on providing information on key biological parameters of several of the major species, including King George whiting, Snapper, Garfish, and Southern calamary.
The Marine Scale system monitors catch and effort fluctuations in South Australia's Marine Scalefish fishery and provides a basis for assessment of fish stocks. Quantity of fish (by species) and effort (by gear) expended in taking the catch is recorded by monthly returns submitted by the commercial fisher.

Respiration rates of copepod larvae and a ciliate from Bowling Green Bay, North Queensland

Laboratory experiments were carried out on copepod larvae and a ciliate (Placus sp.), collected from inshore waters in Bowling Green Bay. Surface seawater was collected at the same time and filtered for later use in experiments. Five series of experiments were conducted on the copepod larvae, which were separated from phytoplankton and other material in the plankton samples, using the phototactic response of the zooplankton. Two series of experiments were carried out on the ciliate, Placus sp., which was collected in an almost pure sample from the study site.A series of experiments consisted of between 5 and 12 measurements on animals from a plankton sample. A new sub-sample of animals, consisting of between 200 and 1300 individuals was used for each measurement. Each series was completed within 2-7 hours of collection, except for one of the copepod samples, when measurements commenced one day after collection.Respiration rates were measured using an oxygen electrode method. At the end of each measurement, the animals were preserved and later counted under a dissecting microscope. For each experimental series, animals were pooled and the size distribution measured with a Coulter Counter TAII.Average biovolume was calculated, based on the diameters of animals in each experimental series. This value was then used to calculate average body wet weight (µg).
 This research was initiated to:1. measure respiration rates of microzooplankton (2. compare the results with published respiration rates of other similar sized animals and net-zooplankton (&gt;200-300 µm body size)3. estimate the relative importance of microzooplankton respiration to total zooplankton respiration in tropical marine ecosystems.

Parent record: Datasets relating to core BAR9403 (off the coast of Sumatra)

We must understand the natural cycles of the oceans to understand the evolution of our climate through geological time. Core BAR 9403 was obtained in 1994 off the coast of Sumatra (5o49.20', 103o61.90'E By investigating the properties and components of this core we are able to reveal some information regarding past oceanographic and climatic systems. Information obtained or inferred from the core include the isotopic composition of oxygen and carbon through time, an age vs. depth profile of the core (revealing sedimentation rates), the relative abundance of planktonic foraminifera over time, and estimates of historical sea-surface temperatures.

Benthic habitat characterisation of Montgomery Reef, Kimberley region, Western Australia using towed video (Towvid)

The AIMS towed video system was used to survey the deeper water (between 10 and 53 metres) to the north and south of the reef. The system was flown at approximately 1 metre above the sea floor with real time analysis of the video footage (AIMS Towvid) used to examine the broad scale distribution of dominant benthic biota. In addition to video footage, a downward facing digital still camera was attached to the bottom of the towed body. The camera was set to photograph the benthos approximately every 5 metres. The high resolution images allowed for a more detailed assessment of the benthic community.
 The objectives of the research were three-fold:1. to provide a broad- and fine-scale characterisation the benthic communities and substratum at Montgomery Reef2. to identify similarities and differences in the benthic communities examined and3. to undertake a detailed spatial analysis to examine and map the distribution of these benthic organisms and communities.This research was the first detailed quantitative survey of the benthic communities of Montgomery Reef. Univariate, multivariate and spatial statistics are employed to examine both the similarities and differences in the distribution and relative abundance of these benthic communities.
 This study is part of a broader regional survey of the Kimberley fringing reefs initiated by AIMS in 2009.

WAMSI Node 3.1.1b and 3.2.2 - Ecosystem Effects of Fishing: finescale coral reef fish surveys Ningaloo Reef - Mandu Sanctuary Zone

From 2006 to 2007 at northern Ningaloo Reef, stereo Baited Remote Underwater Video (stereo-BRUVs) and stereo Diver Operated Video (stereo-DOVs) were used to measure fish assemblages across shallow coral reef lagoon habitats. Four areas were identified including Osprey and Mandu Sanctuary, and Osprey and Mandu Reference Areas which were studied with stereo-BRUV and stereo DOV transects, during two successive summer and winter periods. Each time, six stereo BRUVs and 5 stereo-DOV transects were collected from within 6 coral reef lagoon habitats at 2 well established sanctuary zones and adjacent areas.  The video footage was used to create the raw abundance and length data of different fish species.

2016 SoE Marine Chapter - Pressures - Marine debris

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 marine debris". 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
Marine debris is recognized as a globally important stressor in the marine environment, with increasing reports of impacts on marine biodiversity reported during the last four decades (Gall and Thompson 2015) and upwards of 6-12 million metric tons of plastic waste entering the oceans each year (Jambeck et al. 2015). Marine litter includes consumer items such as glass or plastic bottles, cans, bags, balloons, rubber, metal, fiberglass, cigarettes and other manufactured materials that end up in the ocean and along the coast, and other materials intentionally or unintentionally discarded at sea. In Australia, marine debris has been identified as a key threatening process for threatened and endangered vertebrate fauna. Marine litter also has socioeconomic impacts, it acts as a transporter of invasive species, can be a navigation hazard and there are increasing concerns over the human health risks due to food security issues from seafood (Rochman et al. 2015). With estimates of ¾ or more of marine debris coming from land-based sources and continued growth in plastics production and usage, marine debris is a ubiquitous problem, with high but variable concentrations of marine debris found both in coastal and marine environments (Hardesty et al. 2014). 
DATA STREAM(S) USED IN EXPERT ASSESSMENT
Concentrations derived from a single survey around Australian coastline and at sea, carried out between 2011-2013 as well as data and analyses presented in peer review publications, a recent review of the TAP for marine debris.

Abundance and size of the sponge, Coscinoderma matthewsi, in central Torres Strait (MTSRF Project 1.3.2)

In March 2007, November 2007 and May 2008, between 6 and 11 sites were surveyed on the coral reefs at Keats Island and Yorke Islands (Masig Island and Kodall Island), in central Torres Strait, to determine the abundance and size frequency patterns of Coscinoderma matthewsi. Sites were located at least 1 km apart and at each site, surveys were conducted at both shallow (4-6 m) and deep (10-12 m) depths, with the former generally on the reef flat. Three 20 x 1 m transects were examined at each depth, with transects separated by at least 20 m to retain independence. For each transect, divers recorded every Coscinoderma matthewsi found within 1 m of one side of the transect line. For each transect, environmental factors such as the degree of reef slope and the percentage of dead coral rubble, sand and consolidated limestone rock, free of living organisms were estimated. For each sponge, the substrate type that it was attached to and growing on was recorded. The habitat in which each sponge was growing was also classified as either exposed (living in an exposed microhabitat, such as on top of rock fully exposed to the ambient water flow) or sheltered (in a sheltered microhabitat, such as under an overhang or protected between surrounding rocks). Sponges were also examined for signs of disease.To examine size frequency distributions patterns, the greatest length, width and height of every Coscinoderma matthewsi was measured with a ruler. For graphical interpretation, sponges were grouped into 2 cm size classes. Some individuals of Coscinoderma matthewsi in Torres Strait have a palmate morphology, where large lobes project upwards from the main sponge base. For each measured sponge, the number of lobes were counted and recorded.
 This research was undertaken to gather further information on the abundance, size frequency patterns and preferred habitat of Coscinoderma matthewsi on the reefs around Keats Island, Masig Island and Kodall Island, where previous surveys indicated that Coscinoderma matthewsi was most abundant. The results of these surveys were compared with previous surveys undertaken under the CRC-TS Project in July 2004, December 2005 and November 2006, to determine whether the abundance of Coscinoderma matthewsi varies around Masig Island over time.
 Keats, Kodall and Masig are sand cays, low-lying (&lt;10 m in height) and small in size (&lt;5 km²). Coral reef surrounds all islands, with broken reef connecting Kodall and Masig. The coral reef slope generally starts at a depth of 6 m (MLW) and stops on sand at 15 m, descending at an angle ranging from 20 to 60°. South-easterly trade winds (15-20 knots) are common from April to December, while monsoonal weather patterns with more northerly winds dominate during summer.

Microphytoplankton abundance and composition data collected from the Port Hacking 100m station 1998-2009

Monthly microphytoplankton (~20 - 200 mm diameter fraction) samples were collected from Port Hacking 100m coastal station by hauling a 20 μm mesh net (245 mm diameter, 1.2 m length) with an attached 120 mL plastic jar (no flow meter) from a depth of 50 m from September 1998 to December 2009. Samples were preserved using 3% glutaraldehyde (final concentration) and stored at 4°C prior to microscopic examination. An Olympus BH2 microscope equipped with Differential Interference Contrast (DIC) and Phase Contrast (≤ 400X magnification) was used to identify and enumerate microphytoplankton taxa. In order to characterise the structure of the microphytoplankton community, species presence/absence and abundance were measured. Species presence/absence was estimated by attempting to identify all microphytoplankton taxa present in each sample to species. For some taxa, species-level identification was not possible using routine light microscopy. In such instances, individuals were identified to genus (e.g. Chaetoceros, Pseudo-nitzschia, and Thalassiosira). The length of time devoted to enumerating taxa in a sample varied from 1 hr to 2 hr, as determined using the timed-interval protocol of the Australian Rivers Assessment System (AUSRIVAS) (http://ausrivas.ewater.com.au). Abundance was estimated by counting to a minimum of 100 cells, or 10 traverses, using the Lund cell method (Hotzel and Croome 1999). Trichodesmium erythraeum filaments were converted to cell counts using a conversion factor (30 cells filament-1) that was obtained by averaging the cell counts of 40 filaments (standard deviation: 6.4 cells filament-1).

Holocene evolutionary history and accumulation rates for the granite based Lizard Island Fringing Reef System, Northern Great Barrier Reef

Lizard Island is located in the Northern Great Barrier Reef province, approximately 270km north of Cairns. Reef drilling was undertaken to investigate the Holocene evolution of the fringing reefs of Lizard Island. Radiocarbon dating of the cored coral material was then used to establish the chronology of the reef and to quantify the rate of development. 
Three drill cores were extracted, all from the windward margin because the leeward margin was too deep to access and did not form a conventional reef flat margin. The maximum depth reached was 4.5 m in core L1, with cores L2 and L3 being abandoned after encountering thick sand layers. 
The cores were logged and photographed, and thin sections were made and petrographically examined. Corals that were determined to be in situ (by the orientation of their corallites) and free from internal cement and detritus by microscope examination were selected for radiocarbon dating.
Radiocarbon dates indicate that the fringing reef at Lizard Island started growing directly on an assumed granite basement approximately 6.7 cal kyr BP at approximately 4.5 m below the reef flat surface. The windward margin at Lizard Island approached modern day sea level approximately 4 cal kyr BP. Rates of vertical accretion ranged from 0.5 to 0.7 m/kyr at Lizard Island.
