High resolution acoustic data of reef habitat - Tasmanian East Coast

The principle aim of this project was to map the fine-scale spatial distribution of key abalone habitat impacted by urchins in &lt; 25 m water depth using multibeam acoustic imagery. Detailed substrate type (Pavement Reef, Megaclast Reef, Mixed Consolidated Sediment/Reef and Sand), and kelp coverage maps have been produced for the east coast of Tasmania. Large urchin barrens have been predicted and the minimum quantifiable unit of which small incipient barrens can be detected has been identified using this acoustic water column technique.

This data provides a snapshot of the 2021 distribution of seafloor habitats and associated vegetation distribution, and will assist in the facilitation of strategic decision making for urchin control and abalone management.

All spatial datasets and derivatives of the have been uploaded onto the Seamap Australia data portal for visualisation as a resource for both managers and scientists for further analysis and study. Data packages have been split by fishing block (22-24, 27-30) and are available to download from each of the 'child' records linked to this record (below).

IMOS - Satellite Remote Sensing - SST - L3C - Himawari-8 - 1 day - night time - Australia

This is a regional GHRSST level 3 collated (L3C) dataset on 0.02-degree rectangular grid over the Australasian domain (70E to 190E, 70S to 20N) based on retrievals from the AHI imager on board Himawari-8 satellite. The Bureau of Meteorology (Bureau) produces Integrated Marine Observing System (IMOS) satellite SST products in the International Group for High Resolution SST (GHRSST) GDS2 file formats for Himawari-8 in real time and delayed mode. This product is composed of reprocessed multi-swath SSTskin retrievals obtained from compositing IMOS Himawari-8 hourly L3C files over the night (before dawn).
Every 10 minutes, the Himawari-8 full disk is processed to retrieve SSTs by using the Radiative Transfer Model (RTTOV12.3) and Bayesian cloud clearing method based on the ESA CCI SST code developed at the University of Reading. The hourly product on native grid is then produced by compositing over multiple swaths for the previous 1 hour. Further, L3C-01day SST fields on native grid are obtained by selecting the highest quality data from the hourly SST records with priority being given to the value the closest in time to the product nominal hour.  The L3C-1day night product on native grid is then remapped over the 0.02-degree IMOS grid to compose IMOS L3C-1day night product (Govekar et al., 2021,  https://www.foo.org.au/wp-content/uploads/2021/11/Govekar_FOO_2021.pdf).   The product format is compliant with the GHRSST Data Specification (GDS) version 2.

Assessment of Symbiont Community in Acropora, Isopora, Montipora, and Goniastrea Broodstock Using ITS2 Sequencing (RRAP_ECT2.1; Years 1+2)

This data was collected as part of the Reef Restoration and Adaptation Program (RRAP). Year 1 samples were collected from Acropora kenti (formerly A. tenuis), A. tersa (formerly A. hyacinthus &quot;neat&quot;), Goniastrea retiformis, Montipora digitifera, and Isopora palifera broodstock. Year 2 samples were collected from A. tersa broodstock.  Broodstock colonies used for RRAP Years 1 and 2 experiments were collected in November 2020 and November 2021, respectively. The overall aim was to further our understanding about how the symbiont communities might different within and among broodstock colonies with varying thermal history provenance as this could inform how selective breeding is approached.

Mass coral bleaching and mortality events have increased in frequency over the last 30 years. Genetic interventions like assisted gene flow may speed up adaptation in reefs with less heat-tolerant corals by increasing the frequency of heat tolerance-associated genetic variants; however, the ideal approach to broodstock selection for this intervention remain unclear. To investigate, we collected Acropora kenti (formerly A. tenuis), A. tersa (formerly A. hyacinthus &quot;neat&quot;), Goniastrea retiformis, Montipora digitifera, and Isopora palifera broodstock colonies from reefs along a thermal gradient on the Great Barrier Reef. Fragments were then taken from each broodstock colony for DNA extraction and internal transcribed spacer 2 (ITS2) amplification and sequencing.

Population genetics of temperate subtidal seagrass beds in Tayaritja Sea Country (Furneaux Group of Islands), Lutruwita (Tasmania) (NESP MaC 3.6)

Seagrass beds are a dominant marine ecosystem of Tayaritja (the Furneaux Group of Islands) in the north-eastern waters off Tasmania. Historical coarse mapping has indicated extensive beds of Posidonia, Amphibolis, Heterozostera, and Zostera species, potentially comprising some of the largest and deepest seagrass extents found in temperate Australian waters. However, limited data on the distribution and ecological value of these seagrass habitats represents a significant knowledge gap in understanding Australia's wetland natural assets.

This project mapped the extent, ecological composition, population structure, and blue carbon value of seagrass beds around Tayaritja, in partnership with the Tasmanian Aboriginal Centre. This record specifically describes the seagrass population genetics component of the project.

Leaf tissue samples were collected from four seagrass species: Amphibolis antarctica, Heterozostera nigricaulis, Posidonia australis and Zostera muelleri. Samples were collected from multiple sites around Tayaritja Sea Country and processed for genome-wide SNP genotyping using the DArTseq platform. The dataset includes population-level genetic summary statistics, associated DArT metadata and reports, and raw sequence data used to support assessment of genetic diversity, clonality, population structure and connectivity among sampled seagrass populations.

See the "Lineage" section of this record for full methodology.

Redmap (Queensland) - Sightings of Algae and Plant Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.

Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.

The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.

This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please email enquiries@redmap.org.au.

IMOS - Satellite Remote Sensing - SST - L3S - Single Sensor - 6 day - day and night time - Australia

This is a single-sensor multi-satellite SSTfnd product for a 144 hour period, derived using observations from AVHRR instruments on all available NOAA polar-orbiting satellites.  It is provided as a 0.02deg x 0.02deg cylindrical equidistant projected map over the region 70°E to 170°W, 20°N to 70°S. Each grid cell contains the 144 hour average of all the highest available quality SSTs that overlap with that cell, weighted by the area of overlap.  The diagram at https://help.aodn.org.au/satellite-data-product-information/ indicates where this product fits within the GHRSST suite of NOAA/AVHRR products. The SSTfnd is derived by adding a constant 0.17 degC to the SSTskin observations after rejecting observations with low surface wind speeds (&lt;6m/s by day and &lt;2m/s at night) (see http://www.bom.gov.au/amoj/docs/2011/beggs.pdf). Matchups with buoy SSTfnd observations for the central date indicate typical 2014 biases of &lt; 0.03 degC and standard deviations of 0.6 degC.  Refer to the IMOS SST products web page at http://imos.org.au/sstproducts.html and Beggs et al. (2013) at http://imos.org.au/sstdata_references.html for further information.

Production of this single sensor product ceased in June 2025, due to decommissioning of the NOAA-18 satellite.

IMOS - Satellite Remote Sensing - NOAA20 - 01 day - Ocean Colour - SST

The NOAA20/VIIRS Sea Surface Temperature product is derived from VIIRS 11 and 12 micron spectral bands according to the algorithm described at https://oceancolor.gsfc.nasa.gov/atbd/sst/. This is not a GHRSST-quality product, and demanding applications requiring a high standard of accuracy should consider using one of the IMOS GHRSST products in preference. The VIIRS SST is nevertheless useful primarily because it is measured at the same time as the water leaving radiances used to derive the optical properties (eg chl). This means it is both contemporaneous, and has a matching cloud mask, so it is valuable for applications that seek to combine both SST and optical properties (ie Net Primary Productivity variants). The data set provided here matches the Chl_oci product in temporal and spatial extent.

This SRS dataset covers waters around Australia.

IMOS - Ocean Radar - Coffs Harbour HF ocean radar site (New South Wales, Australia) - Real-time sea water velocity

The Coffs Harbour (COF) HF ocean radar site is located near the point at which the East Australian Current (EAC) begins to separate from the coast.  Here the EAC is at its narrowest and swiftest: to the north it is forming from the westwards subtropical jet, and to the south it forms eddies and eventually the warm water moves eastwards across the Tasman Sea, forming a front with the cold water of the Southern Ocean.  

The connection between coastal and continental shelf waters is fundamental to the understanding of the anthropogenic impact on the coastal ocean and the role of the ocean in mitigating urban marine water quality. The oceans off Eastern Australia and in particular in the region of New South Wales have a complex circulation structure, and are strongly connected with other regional seas and currents. 

The East Australia Current (EAC) flows from tropical regions southward along the NSW continental slope, bringing tropical biota southward. These current structures provide strong physical and biological connectivity, allowing substantial transport and dispersion of biota between regions, and influencing the transport and upwelling of nutrients, which are fundamental to biological productivity.  

The COF HF ocean radar is a WERA phased array system with 16-element receive arrays located at Red Rock (-23.942 S, 151.371 E) to the north of Coffs Harbour and North Nambucca (-24.111 S, 152.713 E) to the south.  The area of focus is off Coffs Harbour where IMOS and the NSW government have mooring sites.  These radars operate at a frequency of 13.920 MHz, with a bandwidth of 100 KHz and a maximum range of 100 Km.  Within the HF radar coverage area surface currents are measured.  Data are also collected from which wind directions and significant wave height can be calculated.

NESP MaC Project 3.14 - Assessing changes in black rockcod abundance and size, 2023-2024 (NSW DPI)

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Assessing changes in black rockcod abundance and size". For specific data outputs from this project, please see child records associated with this metadata.

The black rockcod (Epinephelus daemelii) is a long-lived, reef-dwelling species listed as Vulnerable under Commonwealth and NSW legislation. In Australia it occurs along the coast of New South Wales, including at Lord Howe Island. Although protected from fishing in NSW since 1983, the species is vulnerable to illegal take, incidental capture, barotrauma-related mortality, and degradation of nursery habitats. Long-term monitoring is a high priority for assessing whether recovery actions and spatial protections are improving population status.

This project repeated the broadscale baseline survey of black rockcod across northern NSW and Lord Howe Island, extending a monitoring program that began in 2009–2011 and included smaller key-site surveys every four to five years. Divers surveyed reef sites, photographed and filmed individual fish, recorded habitat and depth, and estimated fish lengths, including with stereo-video where possible. Additional local field capability was built through Indigenous engagement and community-based monitoring activities.

These survey outputs contributed to a 15-year time series (2009-2024) on abundance, occupancy, size structure, habitat associations, and spatial distribution of black rockcod. The results indicated continued low abundance across the species’ surveyed range, while also identifying larger mature individuals and higher abundances in some no-take sanctuary zones. The long-term dataset provided evidence for assessing recovery actions and sanctuary zone effectiveness, informs future monitoring priorities, and supports potential reassessment of the species’ threatened status.

Post release survival in flathead

In fishing trials, the short term survival rates for hook caught flathead (Platycephalus bassensis in Tasmania and P. fuscus in Queensland) were examined to determine critical factors affecting post-release survival.

Biological information (size) and hooking location/damage were recorded and fish held for several days in aquaria to assess survival rates.

In order to relate hooking location and catch rates for a range of hook types (including circle hooks) structured fishing trials and volunteer fishers (using a diary system) provided information on fish size, hook type and hooking location.
