Hydrodynamics and zooplankton community structure in the lee of Helix Reef, central Great Barrier Reef (1992)

Zooplankton were collected over three consecutive nights of the new moon (4-6 January 1992) in an array of 16 light traps anchored downstream of Helix Reef in the central Great Barrier Reef. Three traps were placed within 50 m of the reef crest (A-C) and the remainder were moored in a regular grid pattern across a NW-SE axis. Most traps were cleared several times each night after the lit periods (2100-2200, 2400-0100, 0300-0400). Zooplankton were identified to 53 taxa from the 105 samples taken and abundances counted. Seven clusters were determined using the parameters dates, sampling times, locations, taxa.A two-step depth-averaged hydrodynamic model was applied. The tidal predictions required to force the data were calculated from historical amplitude and phase data, and wind data from nearby Myrmidon Reef. For fine-scale near-reef circulation a two-dimensional depth-averaged hydrodynamic model was nested within the larger-scale model. Boundary forcing data was obtained from sea level and current predictions generated by the regional model.
 To investigate which physical processes determine zooplankton community structure in waters close to coral reefs.

Phytoplankton concentration measurements in Sydney Harbour, Summary.

A study of the response of phytoplankton to rainfall in Sydney Harbour 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].

Understanding fish recruitment processes at Ningaloo Reef

Annual underwater surveys of lethrinid juveniles (&lt;5 cm TL) were collected over thirteen consecutive years across the northern and southern sectors of Ningaloo.
This study focussed on two species of tropical Emperor (Family Lethrinidae) that are common within the Ningaloo lagoon &ndash; the Spangled Emperor (Lethrinus nebulosus) and the Yellowtail Emperor (Lethrinus atkinsoni). Abundance of L. nebulosus and L. atkinsoni were estimated at 11 macroalgae sites within the Ningaloo lagoon and 11 sites within nearby coral reef. Sites were spread along 150 km of the Ningaloo coast, with 12 sites north of Point Cloates (northern sites, six coral and six macroalgae) and 10 sites south of Point Maud (southern sites, five coral and five macroalgae). Lethrinid surveys were conducted in the late Austral summer (February&ndash;March), immediately after the peak recruitment of fish at Ningaloo.
At each site the number and size (to the nearest cm) of all sub-adult (5&ndash;28 cm TL) and adult L. nebulosus (&gt;28 cm TL) and L. atkinsoni (&gt;25 cm TL) within nine 30 &times; 5m transects (1&ndash;6 m deep) were manually recorded by divers before a return run along the same transect recorded all juveniles lethrinids (&lt;5 cm TL) to genus level in a 1m band.  
Surveys for juveniles were repeated annually from 2010 to 2023, while larger bodied lethrinids were included in the annual surveys from 2013 to 2023

Copepod swarms on the central and northern Great Barrier Reef, and Palau

Observations and samples from 200 monospecific copepod swarms of four species (Acartia australis, Acartia bispinosa, Centropages orsinii, Oithona oculata) were made on 11 coral reefs, 2 sea grass habitats, and several marine lakes from the central and northern Great Barrier Reef and in Palau.The date, species and location of each swarm was recorded. Other features recorded were: shape, width and length of swarm; depth of water, distance above substrate, other observations at the time of the swarm such as sky and state of the ocean (calm, etc.). Note that not all features were recorded for all swarms.At Davies Reef, a more detailed study was carried out with vertical density profiles at night and during the day, measurement of copepod size and determination of gender on 190 specimens. Eight swarm sizes were estimated by the use of 3 collection methods (net, plastic bags and photographic images).
 To provide additional information on the density of copepods within swarms.
 Locations:Great Barrier Reef: Adelaide, Big Broadhurst, Carter, Davies, Gilbey, Little Broadhurst; Rib and Yonge Reefs; Lizard and Magnetic Islands.Palau: Western reef, marine lakes on Kaibakku and Urukthapel Islands, in the solution notches surrounding the limestone island complex of Urukthapel, and in the sea grass beds off Koror.

NERP TE Project 2.3 - Monitoring the health of Torres Strait coral reefs (AIMS)

This project conducted a biodiversity assessment of coral communities on Torres Strait reefs to establish a baseline of coral condition and start a longer-term monitoring program of selected coral reefs in the region. The monitoring looked for changes in the condition of coral reefs and documented factors that might contribute to changes including COTS, disease, bleaching, temperature anomalies etc. As part of this project, an early warning system was established for coral bleaching. This will give the Torres Strait Regional Authority (TSRA), Torres Strait communities, industry and other stakeholders, the ability to predict, prepare for and respond to coral bleaching.
Key outputs of this project included:
-biodiversity survey completed for a baseline monitoring survey (Feb 2013) and a repeat monitoring survey (Feb-March 2014). These surveys resulted in a total of 246 coral species recorded during biodiversity surveys in 2013 and 2014. Lists of scleractinian coral species were made in February 2013 at Poruma Island Reef, Aureed Island Reef, Masig Island Reef, Erub Island Reef and Mer Island Reef


deployment of a real time observing station at Thursday Island and Masig (Yorke) Island from 2012 onwards


temperature logger deployments at 15 sites throughout the Torres Strait region


regular reports of environmental conditions including SST, coral bleaching rish, Chlorophyll-a and ocean currents from 2011-2014


Reports and project outputs are available on the eAtlas webpages linked below, and metadata for temperature logger deployments.

Management options to minimise formation of urchin barrens: timed lobster swims - assessment of lobster size and abundance in south-eastern Tasmania

Characterisation of lobster (Jasus edwardsii) abundance and change in abundance at three different sampling sites (Cape Paul Lemanon, North Bay and Fortescue Bay) on the south-east coast of Tasmania, was assessed by GPS tracked SCUBA diver swims of 60 minutes in length whereby GPS was logged approximately every 5 seconds. Large tagged Rock Lobsters were introduced into one of the sampling sites, North Bay (which was closed to fishing). The swims are also being used to assess the impact of reef closure on the local lobster population.

Population genetics of the starfish, Linckia laevigata, in the Indian Ocean and the western Pacific Ocean

A study of the population genetics of the starfish Linckia laevigata throughout the Indian and Pacific Oceans. Seven allozyme loci (GPI, ENO, HK, LP, LT-1, LT-2, SOD) were examined. Variations in gene frequencies of allozymes and common proteins, as well as mitochondrial D-loop DNA (the Restriction Fragment Length Polymorphism - RFLP) were used to estimate connectivity and dispersal between populations in the region.
 Genetic differentiation of populations within and among oceans.To determine whether colour morphs were genetically differentiated.
 1020 individuals were sampled from 2 sites from each of 10 collection locations (Escape, Evening, Davies, Grub, Lodestone, Holbourne, Tern, Sanctuary, 22112, Sykes) between July 1991 and March 1992.608 individuals were added to the previous set (analyses included all samples). These were collected from 18 localities: Australia (Western Australia - Mermaid, Clerke, Imperieuse, Scott and Serangapatum Reefs - Torres Strait, Burke Reef); Fiji (Dravuni, Suva); Guam (Asan, Luminao); Japan (Sesoko, Okinawa); New Caledonia; Philippines (Bolinao, Dumaguete); Solomon Islands (Gizo, Guadacanal).92 individuals were collected from Thailand (Kuta Beach, Phuket Marine Station, Waeo Island) and South Africa (7 reefs in the St. Lucia and Maputuland Marine Reserves); analyses included previously collected data. These samples were of the orange colour morph and were compared the previous data in which the royal blue morph is predominant.

Primary production and nutrients in Darwin Harbour, Northern Territory

On three trips (in February and October 2004 and February 2006) samples were collected in Darwin Harbour.Primary production, respiration, nutrient fluxes and N fixation were measured.Surface-to-near bottom profiles of temperature and salinity were obtained at each site by CTD. Additional samples were analysed for Chlorophyll a, particulate nitrogen, phosphorus and suspended solids.Dissolved inorganic nutrients (ammonium, nitrate, nitrite and phosphate) concentrations were determined. DON and DOP concentrations were calclulated.Experiments were conducted to determine differences in phytoplankton production and pelagic respiration at different stages of the tide. Phytoplankton growth rates were measured on the basis of changes in concentrations of chlorophyll a using the dilution method.Dissolved oxygen concetration and 15N-nitrogen uptake were determined.Net community production (NCP) and community respiration (CR)were estimated. Gross primary production was calculated as the sum of NCP and CR.
 To determine the main sources of primary production and the sources of nutrients supporting growth in a macrotidal estuary, Darwin Harbour.

IMOS - Southern Ocean Time Series (SOTS) - Quality Assessment and Control Report - Salinity Records

This report details the quality control (QC) procedures applied to salinity data collected from the Southern Ocean Time Series (SOTS) moorings between 2006 and 2021. These measurements help to quantify heat and fresh water transfers, help to distinguish Eulerian from Lagrangian influences on seasonal records, and contribute to understanding controls on surface mixed layer depth (and thus light availability to primary production). The quality controlled datasets are publicly available via the AODN Data Portal. This report should be consulted when using the data. 
The Southern Ocean Time Series (SOTS) Observatory located near 141°E and 47°S provides high temporal resolution observations in Subantarctic waters. It is focused on the Subantarctic Zone because waters formed at the surface in this region by deep wintertime convection slide under warmer subtropical and tropical waters, carrying CO2 and heat into the deep ocean, where it is out of contact with the atmosphere. This process also supplies oxygen for deep ocean ecosystems, and exports nutrients that fuel ~70% of global ocean primary production. Local biological production also impacts carbon cycling and the SOTS moorings measure several variables important to these processes.

Effects of periodic trampling on the percentage cover of understory algae within Hormosira banksii dominated rocky intertidal communities

This study assesses the effects of  trampling on Hormosira banksii dominated rocky intertidal algal beds within  Point Nepean National Park, Victoria, over six summers between 1991 and 1996. This dataset gives the percent cover of understory algae within beds of Hormosira banksii after exposure to four levels of trampling for 3 and 5 years.  Sites were located at Cheviot Beach (Harry's pool, Cheviot mid) or Grenade Range, ~ 1 km apart.  Percent cover of understory algae was sampled in the Autumn of 1993 and 1995, after 3 and 5 years of trampling, respectively.  Trampling reduced the abundance of articulated coralline algae at the Grenade Range site but not at either of the two Cheviot Beach sites.
