A new species of marine mite, Mictognathus colemani n. sp. (Acari: Halacaridae) from the Great Barrier Reef

A new species of marine mite, Mictognathus colemani n. sp., was described from the Great Barrier Reef. The male specimen was extracted from a sample of coral sand collected from the reef flat at Turner Cay on 8 December 1998. It is the third known species in its genus and the first species of Mictognathus known to occur in tropical waters. The key to the genus Mictognathus also includes Mictognathus secundus and Mictognathus werthelloides.
 This research was conducted as part of a survey of marine mites from northern Australia.
 The holotype specimen has been deposited at the Townsville branch of the Queensland Museum (Accession Number: QMS105562).

Effects of Sabella spallanzanii physical structure on soft sediment macrofaunal assemblages: effects on colonisation

The introduced European polychaete Sabella spallanzanii has become a dominant feature of sub-tidal habitats in south-eastern Australia.  This study examines the physical effects of  Sabella spallanzanii on macrofaunal assembleges of soft sediments.  Macrofaunal  assemblages  were compared in the presence and absence of real and mimic S. spallanzanni clumps within sub-tidal experimental plots at Clifton Springs, Bellarine Peninsula, Port Phillip Bay, Victoria. The effects of S. spallanzanii on:  i) existing macrofaunal assemblage; ii) distribution of larvae and iii) colonisation of macrofauna were tested.     This dataset gives the colonisation of macrofauna in trays of sediments which had been defaunated and embedded in sediments within  plots of   undisturbed sediment (Control)  and  plots that  contained a single clump of  15 S. spallanzanii individuals (Sabella).  Sediment trays were colonised predominantly by crustaceans, representing 91% of all individuals found.  The presence of Sabella clumps resulted in a significantly higher colonisation of Cylindroleberidid ostracods, but no other effects were detected.

Responses of Bugula neritina, an arborescent bryozoan to the removal of growing tips: short term patterns of regeneration.

In colonial organisms, physical damage or predation can result in the loss of part of the colony.  Although the colony may survive, the loss of part of the colony may alter patterns of growth and reproduction.  In this study, the response of Bugula neritina, an arborescent bryozoan, to physical damage was tested in three experiments: 1) short term regenerative responses to the removal of zooids from growth tips; ii) growth and reproductive responses to damage imposed at different locations within the colony; and iii) the effects of damage produced by a natural predator, the nudibranch Polycera hedgepethi. This dataset gives the growth response of immature colonies over two weeks following the removal of zooids from growth tips of branches from one side of a colony; the remaining side of the colony was left intact. Immature colonies which had undergone four branching events were used in the experiment.  After damage was imposed, colonies were returned to the field site at Williamstown, Victoria.  Colony size (branching score) and the proportion of branches with budding tips were measured on damaged and intact sides of each colony for three weeks between January and February 2000.  Branch tips resumed budding within a few days of damage being imposed and the proportion of budding tips on the damaged sides of the colonies did not differ from intact sides after two weeks.  Damaged sides of colonies were smaller than intact sides two weeks after injury but growth rates were similar by day seven.

Ocean temperatures over time estimated from planktonic foraminifera assemblages in core MD032607 located off South Australia. Estimates are provided for the sea-surface, 50m, 100m, and 150m

In recent years the term 'enhanced greenhouse effect' has become well known in modern society and yet aspects of this possible 'future climate' are poorly understood. The characteristics of the geological record provide a basis to understand this possible future climate through the examination of alternating glacial (cold) and interglacial (warm) stages. Understanding the variability of sea-surface temperature and biological processes in the water column provides insight into general circulation of present and paleo-ocean currents. From core MD032607 the annual mean SST (Tmean) indicates a temperature range of 9oC±0.84oC between Marine Isotope Stage (MIS) 6 to MIS 5, representing the largest sea surface temperature (SST) transition from a glacial to interglacial. The results also suggest that there is more stratification in the water column during interglacial periods as opposed to glacials. Conversely, temperatures gradients are reduced during the Last Glacial Maximum (LGM) and MIS 6 suggesting a well mixed homogenised mixed layer.

WAMSI PhD Top-up - 3.9.4 - Quantifying impacts of the Leeuwin current on the ecology and biogeochemistry of the Ningaloo Reef

Four objectives addressed by the research conducted as part of this thesis were:


To characterise the seasonal variability of nutrient and chlorophyll a concentrations off the north west coast of Australia.


To identify the processes driving the seasonal variability in nutrient and chlorophyll a concentrations off the north west coast of Australia.


To investigate the differences in phytoplankton community, primary production and nutrient uptake between a period of high- and low-flow of the Leeuwin Current in the waters off Ningaloo Reef.


To estimate losses of primary production due to microzooplankton grazing in the waters off the west coast of Australia.


The goal of this research is to understand the processes offshore of Ningaloo Reef that support the production of particulate organic matter that may be available to sustain the reef. This understanding provides the basis to predict the health of the reef under climatic stresses such as El Niño and La Niña events.

Temperate Australian quantitative spatial and temporal abundance data for rocky reef biota (biodiversity): Tasmanian MPA planning surveys and opportunistic surveys

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. 
Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). Further research has collected data in Tasmania, in MPA planning surveys (e.g. St Helens, Waterhouse Region, Low Head, Lillico Beach, Rocky Cape), an oil spill assessment (Low Head), and in studies and surveys in new Tasmania MPAs (Port Davey and the Kent Group).   The data represented by this record was collected in MPA planning surveys and for opportunistic surveys such as the Low Head oil spill assessment. In many cases the dataset involved temporal replication (year scale).

IMOS - Deep Water Moorings - Deep Water Arrays (DA) Sub-facility, East Australian deep water array, East Australian Current 4 Mooring (EAC4) Platform

The EAC4 deep water mooring was deployed in April 2012 at (-27.21 S, 154.65 E) off the Queensland coast, near Brisbane, Australia. The mooring was recovered in August 2013 and the array decommissioned, and a newly configured array (with new moorings) was redeployed in May 2015, and then subsequently decommissioned in July 2022.  
Instrumentation on the mooring includes 75kHz Acoustic Doppler Current Profilers (Long Ranger ADCPs), Seabird SBE37SMPs, temperature loggers (Star Oddi, Starmon Mini) and discrete current meters (Aquadopp 6000).
The mooring will collect a time series of full-depth profiles of water velocity and discrete temperature and salinity measurements. 
The array will consist of 9 current meter and property moorings extending eastward from the Queensland Coastal Node shelf mooring array near Brisbane to the deep ocean. The moorings will be at 500-600 m intervals across the Continental Slope and increasing to 800-1000 m in the deep ocean.  
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 200-m or more.

Taking control of microplastics data: A comparison of control/blank data correction methods

Establishing a robust strategy to account for unintended processing contamination in microplastics research is of interest to the microplastic community who are currently focussed on developing harmonised methods, and to environmental managers who are calling for accurate risk assessment wrt microplastics.
Six commonly used &#39;core&#39; data correction methods were assessed for their suitablity to microplastics research: a) No correction; b) Subtraction; c) Subtraction of mean; d) Spectral Similarity; e) Limits of detection/ limits of quantification (LOD/LOQ) and f) Statistical analysis. An additional 45 variant methods based on these 6 core methods (n=51 in total) were used to correct a dummy microplastics dataset using control data. The dummy microplastics dataset (n=10 identical samples) was created in the laboratory to mimic the laboratory contamination which may arise throughout sample processing and handling. These were free from &lsquo;sample&rsquo; matrix but contained processing solutions and MilliQ water as the surrogate sample matrix. Microplastics processing was conducted following AIMS Microplastics SOPs, and polymer type identified by FTIR and confirmed against the Nicodom Polymer Library.
Data was analysed in Excel and R. Bayesian analysis was also assessed for suitablity.
This work informs work practices for the IMOS long-term microplastic monitoring project, and for all projects conducted by the AIMS microplastics group. This work will also inform the wider microplastics community by starting the conversation towards harmonisation of microplastics data analysis and reporting.

IMOS - National Mooring Network - National Reference Station (NRS) Rottnest Island Mooring

The NRS Rottnest Island Mooring (IMOS platform code: NRSROT) is one of a series of national reference stations designed to monitor particular oceanographic phenomena in Australian coastal ocean waters. The mooring is located at Latitude:-32, Longitude: 115.416.
Physical sampling will be undertaken at each of the reference stations on a monthly basis. The physical samples will be analysed for nutrients, plankton species, both visibly and genetically, and pCO2. Biological sampling will greatly improve Australia's capability to meet its obligations for ecosystem based management and allow many researchers the opportunity to investigate possible long term changes in ecology that are likely to be linked to climate variability and wide scale validation of remotely sensed (satellite) observations of plant biomass.

Multi-temporal mapping of seagrass cover, species and biomass of the Eastern Banks, Moreton Bay

The spatial and temporal dynamics of seagrasses have been studied from the leaf to patch (100 m2) scales. However, landscape scale (&gt; 100 km2) seagrass population dynamics are unresolved in seagrass ecology. Previous remote sensing approaches have lacked the temporal or spatial resolution, or ecologically appropriate mapping, to fully address this issue. This paper presents a robust, semi-automated object-based image analysis approach for mapping dominant seagrass species, percentage cover and above ground biomass using a time series of field data and coincident high spatial resolution satellite imagery. The study area was a 142 km**2 shallow, clear water seagrass habitat (the Eastern Banks, Moreton Bay, Australia). Nine data sets acquired between 2004 and 2013 were used to create seagrass species and percentage cover maps through the integration of seagrass photo transect field data, and atmospherically and geometrically corrected high spatial resolution satellite image data (WorldView-2, IKONOS and Quickbird-2) using an object based image analysis approach. Biomass maps were derived using empirical models trained with in-situ above ground biomass data per seagrass species. Maps and summary plots identified inter- and intra-annual variation of seagrass species composition, percentage cover level and above ground biomass. The methods provide a rigorous approach for field and image data collection and pre-processing, a semi-automated approach to extract seagrass species and cover maps and assess accuracy, and the subsequent empirical modelling of seagrass biomass. The resultant maps provide a fundamental data set for understanding landscape scale seagrass dynamics in a shallow water environment. Our findings provide proof of concept for the use of time-series analysis of remotely sensed seagrass products for use in seagrass ecology and management.
