WAMSI Node 4.3.1b - Trophic interactions in selected south-western Australian estuaries - PhD

This study is aimed at identifying the key primary producers, which support abundant fish species with different feeding modes, in a permanently-open (Swan-Canning) and a seasonally-closed (Wilson Inlet) estuary in south-western Australia. 
The species studied were the sparid Acanthopagrus butcheri (omnivore), the atherinid Leptatherina wallacei (pelagic feeder) and the gobiid Pseudogobius olorum (benthivore). 
Three complementary, quantitative approaches were used:
1) Stomach content analyses to determine the dietary compositions of the above three species and how they vary with body-size and season;
2) Stable isotope ratios of C13/C12 and N15/N14 for fish and their prey; and
3) Fatty acid biomarkers in fish and dietary items. 
Stomach content data demonstrated that size-related changes in diet were evident and that dietary compositions of each species differed among estuaries. Stable isotope ratios of N15/N14 showed that the food web in each estuary contained three trophic levels, while the C13/C12 ratio enabled differentiation of the food chains based on detrital material and plankton. Fatty acid data revealed trophic markers for dinoflagellates in A. butcheri and L. wallacei and for diatoms in P. olorum. 
These findings suggest that:
1) the food resources are partitioned within and among species, 
2) the dietary compositions differ between estuaries and 
3) different sources of organic material support pelagic and benthic food chains

Temperature - Salinity distributions / CTD data at sampling stations on a transect between Dart Point and Callala Beach (S), Jervis Bay

This dataset is a component of the 'Jervis Bay Baseline Studies' project conducted by the Department of Defence, CSIRO and the Australian Defence Force Academy. 
Approximately once per month between 1988-1991, temperature-salinity surveys were conducted on various transects within Jervis Bay and out across the continental shelf. This record describes CTD data from a E-W transect, running from Dart Point in the east, to Callala Beach(S) in the west. Measurements were made using a Neil Brown 'Smart' CTD. On the day of sampling 6 stations were chosen on the transect, with the CTD recorder measuring salinity, temperature and sigma-T through the water column.
Two resources are provided: 1) An excel document providing details of sampling locations and the raw CTD data collected, and 2) A map showing the location of each sampling station.
This is one of nine child records that relate to the parent, 13391430-2ae8-11dd-a735-00188b4c0af8. A pdf outlining the structure and hierarchy of all metadata records relating to this project is available to download through this record. Also available is a pdf of a published working paper documenting this experiment and the results.

Coral-seeding devices with fish-exclusion features reduce mortality on the Great Barrier Reef

In an 8-month field study, we assessed the efficacy of coral-seeding devices with refugia from fishes (i.e., &lsquo;fish-exclusion&rsquo; features) to limit predation-driven mortality of Acropora digitifera spat and microfragments.
Mature gravid Acorpora digitifera (Dana 1846) colonies were collected from Davies Reef (central mid shelf Great Barrier Reef) ahead of Autumn coral spawning (February to March) in 2021. The corals were transported back to the Australian Institute of Marine Science National Sea Simulator (SeaSim) facility and kept in temperature controlled outdoor aquaria. Egg-sperm bundles were collected during spawning from 3-13 colonies and cross-fertilized. The coral larvae were settled onto conditioned, aragonite coral &ldquo;frag plugs&rdquo; (Ocean Wonders) after 7 days. The plugs contained a mixed community of crustose coralline algae and bacteria biofilms that are known to induce settlement of Acorpora corals; these were conditioned in aquaria for 2-months prior to settlement. Five broodstock colonies were selected for microfragmentation 3-months after spawning. Colonies were chiseled into fragments (~10 cm length), then cut into many microfragments (8 mm2). Coral spat and microfragments were held in aquaria until deployment; time in aquaria was equivalent to 4 months for spat and 1 month for microfragments.
Three devices with nominally different levels of grazing exclusion and coral protection were selected for this experiment: (1) a featureless device (open to grazing); (2) a caged featureless device (complete exclusion of grazing); and (3) a device with engineered fish-exclusion features (protection from grazing and our device of interest). The experimental device was designed at AIMS as a part of the Reef Restoration and Adaptation Program (RRAP) and represents the first design of ceramic devices to support field deployment of juvenile corals grown on standard 20-mm (&Oslash;) coral plugs.
Devices with corals were then deployed at Davies Reef onto 4 replicate sites in August 2021. Sites were selected based on their leeward location, shallow depth (&lt; 3 m at high tide), and preexisting population of A. digitifera corals. Devices were surveyed over 3 time points (2, 90, and 240 days) post deployment. Data collection included assessments of coral survival, fish abundance, fish grazing, benthic composition, sedimentation, and wave energy, at the 4 sites. All experimental materials were removed from the reef after 8 months.  
Coral survival and grazing data were analysed using generalized linear mixed effect models (GLMMs) in R statistical software. Redundancy analyses and linear regression models were also used to explore the effects of ecological variables on survival and grazing. Zero-inflated GLMMs were used to compare fish abundance and feeding across sites.

Trace element concentration in whale faeces and muscle, and krill tissue, collected from the Southern Ocean

Whale muscle samples were collected from stranded and dead blue (Baleoptera musculus) and fin (Baleoptera physalus) whales in South-western Australia. Blue, fin, sperm (Physeter macrocephalus), humpback (Megaptera novaeangliae) and pygmy blue (Baleoptera musculus brevicauda) whale faecal samples were collected from coastal waters off Southern Australia by trawling 0.5 mm mesh nets over the surface waters following defecation. Four species of krill (Nyctiphanes australia, Euphausia pacifica, Meganyctiphanes norvegica), including Antarctic krill (Euphausia superba) were collected from various locations worldwide. 
We analysed the concentration of iron, cadmium, manganese, cobalt, copper, zinc, phosphorus and carbon in baleen whale faeces and muscle, and krill tissue using inductively coupled plasma mass spectrometry.

IMOS - South-East Queensland 200m (SEQ200) Mooring Platform

The South-East Queensland 200m mooring (IMOS platform code SEQ200) is part of the East Australian Current (EAC) array. It was initially deployed on the 25/03/2012 at (27.34 S, 153.77 E). The site depth is 200m. This mooring was decommissioned in June 2013.
Observations of currents, temperature, and conductivity are measured.
In conjunction with the SEQ400 mooring and the North Stradbroke Island National Reference Station (NRS NSI), this mooring forms the inshore component of the the EAC mooring array. The East Australian Current (EAC) is the major western boundary current of the south Pacific Ocean. It plays a critical role in the ocean re-distribution of global heat from the equator to the midand- high latitudes. The EAC is relatively stable north of Brisbane, but as the current moves south 2-3 large eddies are pinched off every year. These eddies frequently move onto the continental shelf and close inshore and influence the local circulation patterns. At prominent coastal features the EAC moves away from the coast, driving upwelling which draws nutrient-rich water from a depth of 200m or more. 
Management of this mooring is undertaken by staff from the National Reference Station (North Stradbroke and Maria Island).

SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in December 2008

Flow cytometry data was collected in December 2008, 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 (not bacteria and viruses this cruise).
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.

Phytoplankton concentration measurements in Sydney Harbour - 15th October 2004

A study of the response of phytoplankton to rainfall in Sydney Harbour on 15th October 2004 is reported here.  
Sydney Harbour is an important port and recreational region for the city of Sydney. Phytoplankton can be used as one of the indexes of water quality. The concentration of phytoplankton is influenced by the nutrients in the water and the amount of nutrients is thought to alter according to the urban and industrial wastes that drain from the city of Sydney.    
The amount of phytoplankton before and after rainfall at Pyrmont in Sydney Harbour was observed. The concentration of chlorophyll after a period of rainfall from the 15th October to the 4th November 2004, as measured from the surface to 7m deep, was almost 5 times as much as that as before the rain event. The maximum chlorophyll concentration observed by fluorometer was 27 [ug/litre].

Kimberley Benthic Habitat Survey - Bathymetric Data Files: Raw and Summary

Four locations along the Kimberley coast were video and depth surveyed to describe the substratum type, biohabitat type and the bathymetry of the seabed. Video and depth data was collected between 9 - 29 June 2008 from the vicinity of Gourdon Bay, Quondong – Coulomb Point, Perpendicular Head and Packer Island.
Depth sounding data and tide-gauge data were analysed to generate tide-height corrected bathymetric contour maps for the four survey locations. These maps were used by the Northern Development Taskforce as part of a selection process to rank the suitability of a range of locations for a proposed common-user liquefied natural gas hub precinct.

Monitoring the effects of rezoning the Great Barrier Reef Marine Park

As a result of the Representative Areas Program (RAP), a major rezoning of the Great Barrier Reef Marine Park occurred in July 2004. The objective of rezoning the GBR Marine Park was to conserve biodiversity by ensuring that at least 20% of each of a full range of bioregions within the Marine Park was protected.
To assess the effects of the new zoning plan, pairs of mid-shelf and outer shelf reefs were identified that had both been open to fishing prior to 2004, but one reef in each pair had been rezoned as a &quot;no-take&quot; area in 2004, while the other reef remained open to fishing. Reefs in each pair were located close to each other, were in the same Representative Areas Program bioregion and had similar geomorphology of the NE reef face.
Six pairs of mid-shelf or outer shelf reefs with the appropriate zoning history were selected in each of four localities close to centres of population: Cairns-Innisfail, Townsville, Mackay and the Swain Reefs, and four pairs of reefs were selected in the Capricorn-Bunker Group.
This research was undertaken to monitor the effects of rezoning of the GBRMP, which entailed a large increase in the &quot;no-take&quot; areas within the Marine Park.
These reefs are surveyed using the same survey procedures as those used for the AIMS Long-term Monitoring Project. The survey methods are
1. Broadscale surveys of crown-of-thorns starfish (COTS) and coral cover
2. SCUBA searches on fixed transects looking for agents of coral mortality: Adult and juvenile COTS, Drupella spp. and coral disease
3. Video or still images of benthic organisms on fixed transects
4. Visual surveys of fish on fixed transects
This research was supported by the Marine and Tropical Sciences Research Facility which was represented and managed in North Queensland by the Reef and Rainforest Research Centre Ltd

Effects of damselfish on corals at Britomart Reef, Great Barrier Reef

A series of photographs were taken of experimental conditions over a two-year period and analysed using digitizing techniques to determine direct and indirect effects of fish grazing, damselfish territoriality, and external bioerosion of dead coral substratumPieces of the freshly killed plating coral Pachyseris speciosa were placed under four experimental conditions on Britomart Reef: (1) within cages designed to exclude grazing fish; (2) within the territories of the damselfish Hemiglyphidodon plagiometopon; (3) beneath shade-tops to control for a decrease in light; and (4) outside damselfish territories, fully exposed to fish grazing.Three replicates (A, B, C) were conducted for each set of conditions, placed on the reef 9-11 m deep, and time-lapse photographs taken.Of the 12 plates, 3 subsets were exposed for 8, 12, 24 months.A parallel study was run at the same location and time using the same experimental design to examine the effects of fish grazing on coral recruitment. The number of competitive interactions and successful outcomes (for coral) were recorded between Acropora spat and other sessile epibiota (green alga - Palmophyllum sp.; Foram; red algae - Ceramium procumbens, Centroceras clavulatum, Gracilariopsis rhodotricha, Polysiphonia subtilissima; bryozoans; filamentous green algae; sessile polychaete - sandy tube).
 To determine the relationship between fish grazing, damselfish territoriality, and external bioerosion of dead coral substratum.
 Taxa: scarids (parrotfish); ;acanthurids (surgeonfish); small fish (Pomacentrus molluccensis, blennies); small invertebrates (pagurid and galatheid crabs - Galathea subsquamata). Three categories of borers were identified: Cliothosa hancocki; other sponges (Cliona viridis complex); and 'worms' (included polychaetes and sipunculids - Cleosiphon aspergillum).Coral recruit taxa: Acroporidae (Acropora, Seriatopora hystrix); Caryophylliid or Pectiniid (A); Fungiidae (Fungia A?, B, Compound Fungiid A); Faviid A; Mussid (A, B, C); Oculinidae (Galaxea?); Pocilloporidae (Stylophora?, possibly Pocillipora); Poritidae (Alueopora?, Porites probably P. andrewsi); Unidentified.
