The importance of predation in shaping marine sessile communities at Williamstown, Victoria

Predation on newly settled individuals has been shown to shape sessile invertebrate communities of the northeast coast of North America.  This study tests if this response can also be observed at other geographic locations that support different assemblage of sessile invertebrates.  The effects of predation in early post-settlement assemblages were tested at two locations in Victoria; Workshops Pier, Williamstown and Queenscliff Pier, Queenscliff during the summer of 2005-2006.  At each site, early post-settlement assemblages of sessile invertebrates were established and subsequently exposed to a series of predation exclusion treatments of varying durations.  This dataset gives the abundances of sessile invertebrates on plates at Williamstown Pier after the initial 4 day settlement period, and after subsequent exposure to 3, 15 and 35 days exposure to three predation exclusion treatments. The predation treatments were i) uncaged, no predator exclusion, ii) full 2 mm mesh cage, total predator exclusion and iii) full 10 mm mesh cage, exclusion of large predators only.  In addition two cage control treatments were established to identify if the cages themselves caused a change in the sessile invertebrate assemblages.  Cage controls were partial cages constructed from both 2 mm and 10 mm mesh. The results indicated that, although predators were common, predation did not exert a strong influence on sessile invertebrate communities at Williamstown.

Marine sedimentology and deep sea environments.

Quaternary deep sea sediment cores were collected from Lord Howe Rise; Tasman Sea in February 2006 during a survey of Capel and Fairway basins aboard the R. V: Marion Dufresne (MD Leg 153). Examination of three of these cores (MD060-3032, 3033 &amp; 3036) identified numerous, thin (mm thick), green and grey laminations through the sediment. A thick (40cm) green unit was also observed in one of the cores (MD06-3032). The thin green laminae are interpreted as diagenetically altered volcanic ash layers from volcanic centres in the southwest Pacific, due to the high abundances of the smectite montmorillonite. The grey coloured laminae are an indication of diagenetic alteration of detrital organic material in the sulphate reducing redox zone of the marine sediment, due to their dark grey colour, low clay mineral content and recrystallisation of biogenic carbonate (identified by scanning electron microscopy). The thick green unit is interpreted to be a tephra related to a significant volcanic eruption in the region, most probably from the Taupo Volcanic Zone (TVZ), New Zealand. Approximation on the timing of this event compares with the Potaka Tephra (1.0 Ma) of the TVZ.

High-resolution global bathymetry grids for key Cretaceous and early Cenozoic climate stages

Ocean currents are strongly controlled by seafloor topography. Recent studies have shown that small-scale features with slopes steeper than 0.05° significantly affect subsurface eddy velocities and the vertical structure of ocean circulation patterns. Such slope gradients represent the majority of the present-day oceanic basins. Modeling past oceanographic conditions for key climate stages requires similarly detailed paleo seafloor topography grids, in order to capture ocean currents accurately, especially for ocean models with sufficient resolution (&lt;0.1°) to resolve eddies. However, existing paleobathymetry reconstructions use either a forward modeling approach, resulting in global grids lacking detailed seafloor roughness, or a backward modeling technique based on sediment backstripping, capturing realistic slope gradients, but for a spatially restricted area. Both approaches produce insufficient boundary conditions for high-resolution global paleo models. Here, we compute high-resolution global paleobathymetry grids, with detailed focus on the Southern Ocean, for key Cretaceous and early Cenozoic climate stages. We backstrip sediments from the modern global bathymetry, allowing the preservation of present-day seafloor slope gradients. Sediment isopach data are compiled from existing seismo-stratigraphic interpretations along the Southern Ocean margins, and expanded globally using total sediment thickness information and constant sedimentation rates. We also consider the effect of mantle flow on long-wavelength topography. The resulting grids contain realistic seafloor slope gradients and continental slopes across the continent-ocean transition zones that are similar to present-day observations. Using these detailed paleobathymetry grids for high-resolution global paleo models will help to accurately reconstruct oceanographic conditions of key climate stages and their interaction with the evolving seafloor.

SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in February 2009

Flow cytometry data was collected in February 2009, in waters off South Australia. 
The general purpose of the study is to be able to establish background knowledge on the ecosystem on the continental shelf of South Australia and the impact of upwelling/saline outflow events on microbial communities to ultimately develop a biogeochemical model of the region. Sampling was carried out during cruises conducted on board the RV Ngerin as part of the Southern Australian Integrated Marine System (SAIMOS). During each cruise, the physical, chemical and biological properties of the chlorophyll fluorescence maximum (FM) layer were investigated. Flow cytometry data has been collected for picophytoplankton, bacteria and viruses.
Six main stations have been sampled over the course of the study, five are located on the 100 m isobath, i.e. RS (35.508S, 136.278E), B2 (35.418S, 136.148E), B3 (35.258S, 136.048E), B4 (35.168S, 135.418E) and B5 (35.008S, 135.198E), and one from an offshore station (B1; 36.188S, 136.178E) located southwest of Kangaroo Island. Note that combining the distances between stations (14–25 nautical miles), the average component of the current velocity at middepth along the shelf (0.01 m s21) and the average speed of the vessel (i.e. 9 knots) indicate that different water masses were sampled at each station. Additional samples have on occasion been collected from the National Reference Station (NRS) at Kangaroo Island (35.832S, 136.447E) and the SA Spencer Gulf Mouth Mooring (SAM8SG, 35.25S, 136.690E), where the saline outflow occurs.

Coastal Lake Assessment and Management Tool (CLAM): Dalhousie Creek, Bellingen Shire Council

The Coastal Lake Assessment and Management (CLAM) tool allows stakeholders to assess the social, economic and environmental trade-offs associated with development, remediation and use options for coastal lakes and estuaries. Researchers at the Australian National University (ANU) developed CLAM in 2004 when contracted by the NSW State Government to provide sustainability assessments of 8 coastal lakes. Several projects have since been established directly with local government and NRM groups.
To date, 27 CLAMs have been developed in New South Wales, where they generally fit within estuary management or catchment management plans. To develop these CLAMs and build local capacity to maintain them, ANU-Enterprise Pty Ltd - the commercial company of ANU developed an Accreditation Scheme whereby local consultants are trained in the CLAM approach.

Faunal Surveys of The Rowley Shoal, Scott Reef and Seringapatam Reef: North- western Australia.

The Rowley Shoals, Scott Reef and nearby Seringapatam Reef form a series of large emergent shelf atolls arising from depth of between 300 and 700m along the edge of the broad continental shelf about 260km from mainland north-western Australia. The Rowley Shoals have been described as morphologically the most perfect examples of shelf atolls in Australian waters and appear to represent three distinct stages of atoll formation. Experiencing oceanic water conditions, but with a semi-diurnal tidal range of at least 4.5m, these atolls exhibit an unusual, If not unique, combination of physical environmental and geomorphological characteristics. These are described as a background to the faunal inventories presented in subsequent parts of this publication

Phytoplankton Ecology in the Upper Swan River Estuary, Western Australia - A comparison of nitrogen uptake by seasonal bloom assemblages

Maximum nitrogen uptake rates (Vmax) and preferential nitrogen sources were determined for the different major bloom types between November 1995 and May 1996 in the upper Swan River Estuary.  These uptake rates and preferences were related to the pattern of succession for phytoplankton blooms and diurnal changes in ambient nutrient concentrations for NH4+ in the summer bloom.

The relative abundance (%) of planktonic foraminifera over time in core MD 002361, located on the shelf edge, offshore Western Australia

The advent of deep-sea drilling in the 1950's prompted the use of planktonic foraminifera (unicellular protozans) as palaeoceanographic indicators. They provide a natural archive of past environmental changes due to their global distribution, their prolific productivity and sensitivity to environmental variations. The most abundant species within core MD002361 is the subtropical species Gs. ruber. High abundances =30% are seen during the interglacial periods Marine Isotope Stages (MIS) 11, 9, 7, 5 with peak abundance (37.7%) during the Holocene. Other tropical and subtropical species follow this pattern. The transitional, deep dwelling species Gr. inflata has the most distinct abundance change within core MD002361. This species is absent during the interglacial periods but achieves high relative abundances (~20-30%) during glacial periods.

Investigating the importance, diversity and host specificity of photosynthetic symbionts in marine sponges from tropical and temperate regions

Algae and cyanobacteria form symbioses with many marine sponges, converting energy from the sun to donate to their host, and promoting sponge survival, growth and reproduction. These little-studied symbioses are similar to those between algae and coral, and make a significant contribution to the health of reefs in both tropical and temperate regions. This project will investigate the importance of photosynthetic symbionts in sponges in temperate and tropical regions, their host specificity and diversity. It will map photosynthetic symbiont biogeography and environmental preferences, contributing to an understanding of processes affecting the ecology of coastal reefs.

Dispersal of corals on isolated reefs in Western Australia

Ecologically relevant distances of dispersal were inferred from DNA microsatellite data from broadcast-spawning (Acropora tenuis) and brooding (Seriatopora hystrix) corals at isolated reef systems of Western Australia.576 colonies of the broadcast-spawning coral Acropora tenuis were collected from the Rowley Shoals and Scott Reef systems, and 476 colonies of the brooding coral Seriatopora hystrix were collected from the Rowley Shoals, Scott Reef, and Browse Island. Replicate sites were sampled at most reefs within each system, and samples were collected from the reef slope at the Scott Reef system in January 2004, Rowley Shoals in April 2005, and Browse Island in September 2006. The data for Seriatopora hystrix include 287 individuals genotyped from Scott Reef (see another metadata record for details). At each site (except the two at Browse Island), the exact locations of the sampled colonies relative to a 300 m transect were recorded, along with the GPS coordinates at the beginning of each transect.For Seriatopora hystrix, a total of 8 pairs of colonies sampled from the same site shared the same genotype, compared with 7 pairs for Acropora tenuis. One individual from each of these pairs was removed from the subsequent analysis, resulting in between 21 and 50 individuals analyzed at each site. Details of the microsatellite markers recorded were: the number of alleles (A), the proportion of observed (HO) and expected (HE) heterozygotes per locus and site, and the FIS calculated for each locus and each site (FIS All loci). Averages were also calculated for allele (A All loci), expected heterozygosity for all loci at each site (He All loci), expected heterozygosity across all sites (He All sites); as well as the number of private alleles at each site (Pva), the total number of alleles (Atotal) and arithmetic mean of alleles per locus across sites (Amean). The loci names use a prefix for the species followed by 2, 3, 4 or 5 according to the repeat motif type (di-, tri-, tetra- or pentamer), followed by a number: Sh2-002, Sh2-006, Sh3-003, Sh3-004, Sh3-007, Sh3-008, Sh3-009, Sh4-001 (Seriatopora hystrix); Amil2-006, Amil2-010, Amil2-011, Amil2-012, Amil2-018, Amil2-022, Amil5-028 (Acropora tenuis). Congruent with expectations based on life histories, levels of genetic subdivision among populations were markedly higher in the brooder than in the broadcast spawner. Additionally, significant subdivision for both species between systems (&gt;100 km), and between (&gt;10 km) or within reefs (To gain further insight into degree of isolation, effective population size and the importance of asexual versus sexual reproduction, genetic and genotypic (clonal)diversities vary between the high-latitude, offshore reefs and the low latitude, coastal reefs were tested.

Pelagic fish food web linkages

This data was collected to primarily provide preliminary information on the diets of ten pelagic fish species common to the Northern Prawn Fishery, specifically to investigate any effects of prawn predation by pelagic fish. After the project was initiated the scope of the study was broadened to investigate the age, growth (by otoliths) and reproductive dynamics (by GSI and histology) of these species. Tissue samples from at about 100 specimens representing each species were also taken and stored in DMSO solution and is available for any researcher wishing to undertake a genetic stock structure study. This study was solely funded by CMR as a pilot study. As a result of limited funds, fish specimens were collected opportunistically from recreational fisher donations, commercial catches and from bycatch samples from scientific cruises. As a result, the capture location of the majority of specimens does not have a lat/long, and is generally only identified by the general area of capture (i.e. 'Weipa' or 'Gladstone'). The method of capture was recorded to the best of our knowledge (i.e. hook and line, gillnet etc), although actual gear specifications and shot information were generally not available.
