Patterns in the distribution of sediment fauna on the central Great Barrier Reef

The sediment environment and fauna from reefs in a broad transect across the Great Barrier Reef were quantitatively surveyed. The study was conducted on six reefs in two transects across the continental shelf in the central region of the Great Barrier Reef. Each transect consisted of one inner shelf reef (Pandora or Phillips) located approximately 18km from the coast, one middle shelf reef (Rib or Lodestone) approximately 70km from the coast and one reef on the outer edge of the continental shelf (Myrmidon or Dip) approximately 110km offshore.Within each reef, three or four sites were sampled representing the different sediment environments. Sites were placed at intervals along the gradient of wave energy from shallow windward reef flat to deep leeward lagoon. On the inner shelf reefs, which have no distinct lagoon, sites were positioned on the windward and leeward sides according to the prevailing south east trade wind.One transect of three reefs (Pandora, Rib and Myrmidon) was sampled on four occasions at approximately three monthly intervals throughout a year. The second transect (Phillips, Lodestone and Dip) was sampled once.
 This study was undertaken to investigate the spatial variability of reef sediment fauna at three levels:1) among reefs along a cross-shelf transect2) among reefs at similar positions along a cross-shelf transect3) among zones within reefsTemporal variability in community structure was also investigated to determine whether distribution patterns were persistent over time.Sediment analysis was also carried out to determine whether there was a relationship between sediment characteristics and faunal community structure.
 Sediment samples were taken with a cylindrical PVC corer of 55mm internal diameter, which was pushed manually to a depth of 200-250mm into the sediment. At each site 15 (1st sampling occasion) or 20 (all subsequent occasions) cores were collected for faunal analysis. Sampling was designed to minimise the effects of local patchiness. Four sets (3 on the 1st occasion) of five cores were taken from an area about 1m2 and the sets were spaced about 4m apart. The five cores in each set were bulked to form the basic sample unit (119 cm2).At each site, one additional core was collected for analysis of sediment characteristics on each occasion.

Seamap Australia UNVALIDATED National Benthic Habitat Layer

The Seamap Australia National Benthic Habitat Layer (NBHL) is a compilation of benthic habitat datasets obtained from various sectors including research, government, industry and community sources, across Australia. Disparate datasets are integrated into a single national-scale benthic habitat database, and classified uniformly under a national classification scheme implemented as a controlled vocabulary (https://vocabs.ardc.edu.au/viewById/129).
For acceptance into the 'formal' (validated_ Seamap Australia NBHL (see https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a), source habitat datasets must meet a set of Acceptance Criteria (documented in https://seamapaustralia.org/wp-content/uploads/2023/01/SeamapAustraliaDataAcceptanceGuidelines.pdf). 
Broadly speaking, for inclusion in the Seamap Australia NBHL, datasets must:
(1) be well-described by metadata or associated documentation;
(2) employ a single, consistent classification scheme which avoids non-deterministic or ambiguous terms;
(3) bequality-controlled by the provider prior to contribution;
(4) beacquired using an established and community-endorsed form of data collection (eg satellite, aerial or acoustic remote sensing); and
(5) have documented evidence of ground-truthing validation at the time of data collection (e.g. drop camera, towed video, benthic grabs).
This record describes habitat datasets that meet Acceptance Criteria 1-4, but have not been validated/ground-truthed and are therefore ineligible for inclusion in the formal Seamap Australia NBHL. They have been synthesised and uniformly classified using an identical methodology to the NBHL, but represent an intermediate collection of habitat datasets that would benefit from field ground-truthing in order to validate the habitat classifications.
The Seamap Australia synthesis of unvalidated habitat datasets can be viewed, analysed and downloaded from the Seamap Australia data portal (https://seamapaustralia.org/map). This dataset should be considered a “live” asset and will continue to develop as more unvalidated habitat datasets are collected or made available. 
The most current (2024) version of the data is available from the following endpoints:
WMS: https://geoserver.imas.utas.edu.au/geoserver/seamap/wms
WFS: https://geoserver.imas.utas.edu.au/geoserver/seamap/wfs

RAN CTD Profile Data - HMAS LEEUWIN ProjectID: HI392LEE_H From: 2004-07-02 To: 2004-08-19

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 50 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI392LEE_H from HMAS LEEUWIN. 
The CTD was manufactured by Falmouth Scientific and is the "2-inch Micro CTD" model. This CTD type is referred to operationally as the HS_CTD. This CTD is fitted within an inductive type conductivity cell, a platinum thermometer and silicon pressure sensor.
The CTD temperature sensor is calibrated on the ITS-90 temperature scale against a master CTD using a controlled temperature bath. The pressure sensor is calibrated using a Druck Pressure Calibrator. The conductivity sensor is calibrated in a temperature controlled bath against seawater samples of known conductivity.
The HS_CTD is lowered and raised by a hand winch sampling at a rate of 1.83 Hz. Data files were recorded in the downcast and upcast direction but most data is from downcasts due to higher quality. Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals and converted to netCDF format files. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.

GBRLSH: Lizard Island Shelf Mooring component of the GBR Mooring Array

GBRLSH: Lizard Island Shelf Mooring component of the GBR Mooring Array
 Northern GBR - Lizard Island MooringsThe moorings in the northern area around Lizard Island are designed to detect two phenomena. The first is to measure the northern arm of the bifurcation where the westward South Equatorial Current impacts the reef and splits into two streams, one traveling north and one travelling south along the outer GBR. The bifurcation point varies latitudinally seasonally and so the variability is to be monitored. The slope mooring is located near Jewel Reef (GBRLSL).The other process being measured is the cross shelf movement of water onto the GBR shelf. As the outer ribbon reef is well defined in this area most of the exchange is confined to narrow reef passages and the entrance of Cormorant Passage has been occupied (GBRLSH).
 The Mooring array is part of the GBROOS or Great Barrier Reef Ocean Observing System project which in turn is part of the Australian Integrated Marine Observing System or IMOS.

Natural male-female interactions and territoriality in the fiddler crab Uca capricornis

The behaviour of U. capricornis is not well-known. Consequently, observations were made for approximately 1100 hours over 4 seasons to obtain a general picture of their social system and behaviour. The study was conducted on a large population of Uca capricornis in the vicinity of the mangrove boardwalk in the East Point Reserve, Darwin. Fieldwork was conducted yearly from November-January, 2002-2006. 
To obtain a more detailed description of the relationship between males and females, the natural interactions between males and females living as nearest neighbours were recorded. Twenty-one pairs were filmed from overhead for a period of 30 minutes. Any activity was noted, as was any interactions with intruders. 
Territoriality was also examined, providing the overall area covered by the crabs within the half hour. By aligning the male and female territories with their respective burrows it was possible to determine the area overlap between them.

Diffusion culture experiments using natural phytoplankton from the Great Barrier Reef

Seventeen experiments were carried out between April 1983 and June 1985 to measure in situ growth rates of phytoplankton communities and constituent species in mid- to outer-shelf waters of the central Great Barrier Reef. Growth rates of identifiable phytoplankton taxa, composite groups of phytoplankton (eg microflagellates) and size classes were calculated from changes in cell numbers or chlorophyll concentration occurring while size-fractionated natural phytoplankton assemblages were incubated in situ within diffusion chambers.
Growth experiments were carried out either in the lagoons of, or most commonly, in waters immediately adjacent to three reefs in the central GBR province, Myrmidon Reef, Rib Reef and Davies Reef. Myrmidon Reef was selected to typify conditions found on the outer shelf and in oceanic waters of the western Coral Sea. Located on a protrusion extending seaward from the continental shelfbreak, the sheltered northern side of Myrmidon Reef is exposed to oceanic waters in the southward flowing East Australian Current. Davies Reef and Rib Reef have mid- shelf locations and are surrounded by waters typifying the reef matrix and outer GBR lagoon. Sites at or near reefs for individual experiments were selected to enable safe deployment of diffusion chambers at depths corresponding to desired light penetration depths.
Water samples for dissolved nutrient, chlorophyll, phaeophytin, temperature and salinity analyses were collected daily from incubation depths at the mooring sites.
At most deep water stations underwater light profiles were measured to determine irradiance levels at the depths of incubation.
The purpose of these experiments was to measure in situ growth rates of phytoplankton communities and constituent species in mid- to outer-shelf waters of the central Great Barrier Reef.

IMOS - Deep Water Moorings - Southern Ocean Time Series (SOTS) Sub-Facility

The Southern Ocean Time Series (SOTS) sub-facility provides high temporal resolution observations in sub-Antarctic waters.  Observations are broad and include measurements of physical, chemical and biogeochemical parameters from multiple deep-water moorings.  The emphasis is on inter-annual variations of upper ocean properties and their influence on exchange with the deep ocean.  The time-series provided permit investigation into issues of ocean physics and chemistry, climate change, carbon cycling and biogeochemical controls on marine productivity.  These moorings provide cost-effective observations and overcome the infrequent availability of ships in the region.  
The SOTS site is located in the sub-Antarctic Zone (SAZ), southwest of Tasmania, near 47S, 142E. SOTS observations are made from
1) a deep ocean sediment trap mooring, used to collect sinking particles to quantify carbon transports.  This mooring also provides current meter measurements and a deep ocean CTD to measure heat contents below the depth of ARGO profiling float measurements.
2) the Pulse biogeochemistry mooring, used to measure upper ocean carbon cycle and phytoplankton productivity processes included sensor measurements of dissolved gases (O2, N2) and bio-optical properties.  This mooring also collects water samples for measures of dissolved carbon and nutrients, and phytoplankton microscopic identification. Instrumentation was moved to the FluxPulse mooring in 2016, and then to the SOFS mooring (below).
3) additional biogeochemical sensors (CO2, O2, bio-optical, and bio-acoustic devices) mounted on the nearby Southern Ocean Flux Station air-sea flux mooring (and managed by the Air-Sea Flux Stations sub-facility). Instrumentation was briefly moved to the FluxPulse mooring in 2016.

NESP TWQ Project 3.3.2 - Science evaluation of coastal wetland systems repair projects across GBR catchments, 2017-2019 (JCU)

State and Federal agencies are funding many GBR wetland system repair projects (Mungalla wetlands $1.2M; Reef Trust/Greening Australia $4M; Restoring Burdekin Coastal Ecosystems $837K; Roundhill Creek wetland/FHA $65K, Babinda Swamp Constructed Wetland ~$1.97M). The problem is no scientific data evaluates their success; this project partners with NRMs to fill this R&amp;D gap. Using advanced scientific hydrological and ecological techniques we will generate data to evaluate repair efforts, providing surety to government funding agencies. This project will provide a platform to attract significant private and philanthropic investors, looking to fund large-scale wetland repair projects, via emerging carbon and nutrient trading schemes.

Theme 1B: Ecological patterns and processes in intertidal and subtidal soft-sediment habitats.

Research is focussed on the processes causing and maintaining patterns of distribution and abundance of animals and plants in coastal habitats (Program 1 - Ecology in Coastal Habitats). Without a good understanding of the ecology of species in these habitats, the interactions among the species and the relationships among patches of similar or different habitat, it is not possible to solve problems in the management of coastal change.
Local mangrove forests, salt marshes and mud-flats are habitats for a large variety of animals and plants about which relatively little is known. Apart from research into patterns and processes in these ecological systems and work on environmental impacts and restoration, members of the Centre are doing experimental work on the consequences of fragmentation of habitat, connections with and interactions between different estuarine habitats.
The Centre for Research on Ecological Impacts of Coastal Cities (EICC) has generated many scientific papers and theses from research projects on intertidal and subtidal soft sediments. The link to the URL provided in this record provides a link to this research.

Video Assessment of Population Size Structure and Habitat of Greenlip and Roes Abalone

The team is developing a system to enable the commercial abalone divers to undertake stock measurements using underwater video during their fishing day. The footage is then analysed by WAMRL staff.
The project takes advantage of the divers' access to vast and often remote areas of the fishery, which would be very expensive to replicate, and provides the Research Division with a means of measuring stocks from video footage.
The project involves calibration of equipment, measurement of accuracy of techniques and trialling of the efficiency of the divers skill and involvement.
The project will also
* determine the reliability and usefulness of underwater digital video in getting cost-effective, fishery-independent counts and abalone (as an alternative to traditional manual techniques);
* provide a comparison of abundance and stock structure information (between and within years) for main fishing videoed; and
* develop a time(cost) efficient computer program to extract (frame grab) and measure (within frame) abalone on videotape, and a database where images and data from video can be stored, accessed and analysed.

Industry is supporting the project by providing time, effort and resources such as boats and equipment in order to complete the field work of recording the video footage. Industry is also involved with research staff to calibrate and document efficiency of the technique.
