Utilisation of the introduced New Zealand screwshell (Maoricolpus roseus) by native hermit crabs in eastern Tasmania - depth-related variance in shell occupancy

Interactions between native and introduced species can help to elucidate the impact of exotic species on the broader community. This work examines utilisation of an introduced gastropod, the New Zealand screwshell (Maoricolpus roseus) by native hermit crabs in eastern Tasmania.

Variation in shell occupancy by hermit crabs was examined across different depths (10, 20, 30 and 40m) within a single site (Dennes Point, SE Tasmania). 

Sediment cores were taken from 10 and 20 m to compare sediment size structure. A sediment preference trial using the hermit crab Paguristes tuberculatus was also carried out (using sediment from 10m and 20m) to try and determine the low level of hermit crab occupancy at 20m (compared with that at 10m).

IMOS - AusTemp - Heat stress and marine heatwave and cold-spell monitoring metrics for the Australian Coast

This dataset contains the marine heatwave (MHW) and marine cold spell (MCS) categories from the 1st of January 2012. The SST Atlas of Australian Regional Seas (SSTAARS) daily climatology (Wijffels et al., 2018) is used as the baseline for developing heat-stress monitoring metrics. SSTAARS daily 90th-, 50th-, and 10th-percentile thresholds are applied to classify MHW and MCS according to established Hobday definitions. The dataset also contains the Sea Surface Temperature anomalies (SSTa), calculated by comparing the current SST to a monthly SSTAARS climatology, and the Degree Heating-Days (DHD) metrics, calculated by accumulating the daily positive Sea Surface Temperature anomalies (SSTa). When SST cannot be calculated due to cloud cover, the grid cell is left blank (white in web plots, transparent in Google Earth) to indicate missing data.

This product follows on from the Bureau of Meteorology's (Bureau) decommissioned ReefTemp Next Generation, a high resolution mapping product that provided information on coral bleaching risk for the Great Barrier Reef region for 2012-2024. In the first stage of operational deployment of AusTemp, the current operational satellite-derived, night-time-only MultiSensor Level 3 Super-collated (MS L3S, Govekar et al 2022) sea surface temperature (SST) product is being used to define heat stress and MHW/MCS monitoring metrics. A new GeoPolar MultiSensor L3S adds geostationary Himawari-8/9 data to the polar-orbiting satellites. It provides significantly improved spatial coverage, due to Himawari's 10 minute sampling period filling in SST gaps caused by fast moving cloud, with an additional 20% data on average over the MS L3S product (Govekar et al 2024).

The improved spatial and temporal resolution of AusTemp allows for high-detail mapping of MHWs across Australian waters, supporting accurate assessments of local ecological impacts, including coral bleaching and mortality in marine species. These tools are valuable for conservation, reef management, aquaculture, and fisheries, helping stakeholders manage the growing risks associated with marine heatwaves in a warming ocean.

Marine Futures Project - Rottnest Island - reef habitat

The Marine Futures Project was designed to benchmark the current status of key Western Australian marine ecosystems, based on an improved understanding of the relationship between marine habitats, biodiversity and our use of these values. Approximately 1,500 km2 of seafloor were mapped using hydroacoustics (Reson 8101 Multibeam), and expected benthic habitats "ground-truthed" using towed video transects and baited remote underwater video systems. Both sources of information were then combined in a spatial predictive modelling framework to produce fine-scale habitat maps showing the extent of substrate types, biotic formations, etc.

Surveys took place across 9 study areas, including Rottnest Island, a popular family holiday destination just 20 km off the Perth coast. One of the main drawcards of the island is the diverse marine life inhabiting the surounding waters, which Western Australian locals and tourists can experience by snorkelling, diving, boating and fishing.

The marine environment around Rottnest includes seagrass meadows, kelp-covered reef tops, coral patches, and sponge gardens in deeper water. As a result of the warm, southward flowing Leeuwin Current, the island represents the southern limit of the distributions of many tropical corals and fish. The marine life around Rottnest therefore represents a unique mix of tropical and temperate species and habitats.

IMOS - Satellite Remote Sensing - SNPP - 01 day - Diffuse attenuation coefficient (k490)

The SNPP satellite platform carries a VIIRS sensor that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the diffuse attenuation coefficient (Kd) at 490nm wavelength which provides information on how light is attenuated in the water column. It is defined as the scaling length of the exponential decrease of the downwelling irradiance, and has units (m^-1). The VIIRS K490 product estimates Kd at 490nm wavelength, using a semi-empirical model based on the ratio of water leaving radiances at 490nm and 555nm. The algorithm is described at https://oceancolor.gsfc.nasa.gov/atbd/kd/.

Abalone fishing block 28 - High resolution acoustic data of reef habitat

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.

Data for download has been split by fishing block (22-24, 27-30). This record describes FISHING BLOCK 28. The following data products are available for download, for each fishing block:
• 50cm resolution bathymetry
• 50cm resolution substrate type (Seamap Australia classification)
• bathymetry derivatives (seabed slope, curvature, rugosity, 1 and 2m contours)
• water column data - 1m mean signal
• water column data - 9m2 raw block statistic
• water column data - vegetation likelihood classification

See associated records for access to data from other fishing blocks (22, 23, 24, 27, 29, 30).

NESP MB Project A9 - Grey Nurse Shark CK-MR Population Estimate – East Coast

This record provides an overview of the scope and research output of the NESP Marine Biodiversity Hub project "Grey Nurse Shark CK-MR Population Estimate – East Coast". For specific data outputs from this project, please see child records associated with this metadata.

A review of the 2002 National Recovery Plan for Grey Nurse Shark (DEWHA 2009) concluded it was not possible to determine if the east coast population had shown any signs of recovery (DoE 2014); recommending a new recovery plan be developed for this species. A primary objective of the new recovery plan (DoE 2014) is to improve knowledge of GNS population status. This will require a robust estimate of population size and trend – something that has not been provided to date. This project will use genetic SNP data to inform close kin-mark recapture analysis to estimate population size and trend, and provide guidance on future monitoring strategies for the east coast population of grey nurse shark. 

Planned Outputs
• Tools to refine and integrate CK-MR and species demographic data for population assessments of a key threatened species at a national scale (combining knowledge developed under this project combined with similar techniques being applied under NESP to euryhaline sharks and white sharks). 
• A national estimate of (census) population size and trend for the eastern Australian population of grey nurse shark will be developed to fulfil the highest priority actions of the National Recovery Plan.
• Identify national strategies to guide future monitoring of grey nurse shark populations.
• The project will provide peer-reviewed additions to the scientific literature that will add to the science-support for the development and implementation of policies to support the ecologically sustainable management of Australia’s marine environment.

IMOS - Ocean Radar - Rottnest Shelf HF ocean radar site (Western Australia, Australia) - Real-time sea water velocity

The Rottnest Shelf (ROT) HF ocean radar system covers an area which includes Rottnest Island and the Perth Canyon to the north-west.  The Perth Canyon has the highest marine biodiversity in the region with whale and fish aggregations, and high primary and secondary productions which are controlled by the physical oceanographic processes.  

Combined with the dynamics of the Perth Canyon is the dominant Leeuwin Current which produces a wake on the leeward side of Rottnest Island.   This is a topographically induced up-welling and associated primary and secondary productivity.  The region is influenced by Swan River outflow, submarine groundwater discharges , and waste-water outfalls.  

The ROT HF ocean radar is a WERA phased array system with 16-element receive arrays located at Fremantle (32.031 S, 115.746 E) and Guilderton (31.342 S, 115.489 E).  These radars operate at a frequency of 8.512 MHz, with a bandwidth of 33 KHz and a maximum range of 200 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.  

The ROT area of coverage has a small overlap of commonly observed ocean with the Turqoise Coast (TURQ) SeaSonde HF ocean radar system on its north side.  Together, the ROT and TURQ systems provide continuous monitoring of the shelf from Fremantle to Jurien Bay.

Abundance and distribution of coastal, inshore zooplankton in the Huon Estuary and D'Entrecasteaux Channel, Tasmania: Sampling trip 13/10/2005

Mesozooplankton community composition and structure were examined throughout the D’Entrecasteaux Channel, Huon Estuary and North West Bay,  Tasmania, from November 2004 to October 2005, the data represented by this record was collected on the 13/10/2005.

The composition of the mesozooplankton community was typical of inshore, temperate marine habitats, with seasonally higher abundance in summer and autumn and lower numbers in winter and spring. Copepods were the largest contributors to total abundance across all seasons and stations, while cladocerans and appendicularians were proportionally abundant in spring and summer. The faecal pellets of these three main groups, along with those of krill and amphipods, also contributed significantly to material recovered from sediment traps. Meroplanktonic larvae of benthic animals showed short-term peaks in abundance and were often absent from the water column for long periods. Spatially, North West Bay and the Channel had a higher representation of typically marine species, including Calanus australis and Labidocera cervi, while truly estuarine species, such as the copepod Gladioferens pectinatus, were more important in the Huon Estuary.

IMOS - OceanCurrent - Gridded sea level anomaly - Near real time

Gridded (adjusted) sea level anomaly (GSLA), gridded sea level (GSL) and surface geostrophic velocity (UCUR,VCUR) for the Australasian region. GSLA is mapped using optimal interpolation of detided, de-meaned, inverse-barometer-adjusted altimeter and tidegauge estimates of sea level. GSL is GSLA plus an estimate of the departure of mean sea level from the geoid – mean sea level (over 18 years of model time) of Ocean Forecasting Australia Model version 3 (OFAM3). The geostrophic velocities are derived from GSLA and the mean surface velocity from OFAM3. 

The altimeter data window for input to the Delayed Mode (DM) maps is symmetrical about the map date. The width of the window is dependent on the number of altimeters flying at the time and ranges from 30 days to 14 days. The altimeter data window for Near Real Time (NRT) maps is asymmetrical about the analysis date (-21 to 4 days). For both NRT and DM, altimeter data is weighted by the difference between the analysis date of the map and the time of each altimeter observation.
