RV Investigator Voyage IN2023_V07 EM-APEX Profiling Floats Data

This record describes the EM-APEX Floats data from the Marine National Facility (MNF) RV Investigator voyage IN2023_V07, titled "SWOT-ACC: smaller scales of the Antarctic Circumpolar Current in a meander south of Tasmania." The voyage took place between November 15, 2023 and December 20, 2023 (AEST), departing from Hobart and returning to Hobart. Two EM-APEX floats were deployed to measure high-resolution profiles of temperature, salinity, pressure, and horizontal velocity in the Antarctic Circumpolar Current. These observations provide critical subsurface data to link small-scale variability in sea surface height observed by the SWOT satellite with underlying ocean circulation, eddy activity, and cross-front transport of heat and carbon. Tracking of the EM-APEX floats is available via the interactive map link, using hull numbers f10331 and f10317.

RV Investigator Voyage IN2023_V05 Deep-Towed Camera Imagery Data

This dataset comprises still images collected using a deep-towed camera during the RV Investigator voyage IN2023_V05, titled "Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 1)." This was the first survey of the South East Australian Marine Ecosystem Survey (SEA-MES) Project. The voyage was conducted between 27 June 2023 and 29 July 2023 and sampled the south-eastern Australian continental shelf and upper slope from the Freycinet Peninsula to north of Eden.

The deep-towed camera was deployed along survey transects to capture imagery of benthic habitats and associated fishes. The images provide visual records of seafloor characteristics, habitat structure, and faunal assemblages, supporting the classification of habitat types and identification of fish species.

The dataset supports assessments of habitat–fauna relationships, validation of trawl catch data, and long-term monitoring of ecosystem change within the SEA-MES study region, contributing to the establishment of new biological and environmental baselines for south-eastern Australia.

eDNA Data from RV Investigator voyages

This dataset leverages environmental DNA (eDNA) technology to assess marine biodiversity in Australia’s offshore waters across a range of locations and depths. eDNA refers to genetic material (DNA) extracted from environmental samples such as water, soil, or air, rather than directly from organisms themselves. The eDNA in this dataset is used to identify a wide array of marine species, from microscopic plankton to larger marine life, offering a non-invasive method of biodiversity monitoring. The data has been gathered from numerous oceanographic expeditions aboard the RV Investigator over several years. These voyages span different regions of Australia's expansive offshore waters, allowing for a broad and comprehensive assessment of marine life across varying ecosystems, from shallow coastal waters to deeper, more remote offshore areas. This rich dataset includes thousands of individual water samples, collected at different sampling sites across the nation. Each sample provides genetic insights that are then analysed to build an inventory of species, revealing patterns of biodiversity that might otherwise be challenging to track with traditional surveying methods.

eDNA Data from the RV Investigator South-East Australian Marine Ecosystem Survey (SEA-MES) voyages (IN2023_V05 and IN2024_V03)

This dataset is focusing on using environmental DNA (eDNA) to measure offshore marine biodiversity in Southeast Australia. The eDNA samples were collected during two SEA-MES voyages aboard the RV Investigator: IN2023_V05 (July 2023) and IN2024_V03 (May 2024). Sampling sites spanned the continental shelf, from Tasmania to Batemans Bay, NSW, with water collected from both surface and bottom depths via Niskin bottles and a deep-tow camera system. A total of over 100 CTD deployments were conducted across these sites, providing comprehensive spatial coverage.

The dataset includes processed eDNA metabarcoding results, containing sequence read counts and taxonomic data derived from DNA sequences, with a focus on fish but extending across the full tree of life, including bacteria, invertebrates, and vertebrates. Over 180 million sequences were generated, using a variety of markers such as mtDNA 16S (fish), mtDNA COI Leray (metazoans), and V4 18S (eukaryotes). This dataset is valuable for understanding marine biodiversity in southeast Australia and advancing offshore eDNA techniques.

RV Investigator Voyage IN2024_V01 Bongo Net Data

This record documents bongo net data collected during the Marine National Facility (MNF) RV Investigator voyage IN2024_V01, with the title "Multidisciplinary Investigations of the Southern Ocean (MISO): linking physics, biogeochemistry, plankton, aerosols, clouds, and climate". The voyage took place between 2 January 2024 and 5 March 2024 (AEST), departing from Hobart and returning to Fremantle. MISO investigates how interactions between the atmosphere, ocean, and biosphere control processes such as cloud formation, iron supply to marine life, ocean carbon uptake, and drivers of rapid change in the deep ocean. Zooplankton were collected at 13 stations across polar, subantarctic, and subtropical regions, representing a range of temperatures and nutrient concentrations. Sampling was conducted using a double-barrel Bongo net (335 μm mesh) towed to 70 m depth for 10 minutes at each station.

Argo Data

Argo is an international collaboration that collects high-quality temperature and salinity profiles from the upper 2000m of the ice-free global ocean and currents from intermediate depths. The data comes from more than 3000 battery-powered autonomous floats that spend most of their life drifting at depth covering most of the world oceans. At typically 10-day intervals, the floats rise to the surface over about 6 hours while measuring temperature and salinity. Satellites determine the position of the floats when they surface, and receive the data transmitted by the floats. The float then returns to its original density and sinks to drift until the cycle is repeated. Floats are designed to make about 150 such cycles. Argo Australia provides real-time observations of the oceans around Australia by maintaining an array of autonomous profiling floats. Data and information regarding Argo Australia and the International Argo program can be found at the Argo Australia web page (see data link below). CMAR holds a mirror of the data from the US Argo server for internal project access, this is regularly updated. (see data link below).

ACTGOV RFMP - Fuel Break Upgrades

This dataset displays the position and extents of fuel breaks that have been identified to be upgraded in the RFMP 2019-28. Strategic fuel breaks are usually located between assets and surrounding rural areas or bushland. Fuel breaks typically consist of an area of variable width next to an existing track or road where bushfire fuels are maintained at lower levels. The lower fuel levels within fuel breaks result in much reduced fire behaviour. In this way, they provide a defensible space in which fire fighters may work with increased safety to protect assets, usually associated with back-burning activities during fire suppression operations. They also provide an opportunity to ‘break-up’ fire runs and assist with prescribed burning operations.

ACTGOV Regional Fire Management Plan 2019-2028

Due to the level of impact across the landscape during the 2019-20 fire season, the Regional Fire Management Plan (RFMP) 2019-28 was revised. With three years remaining before the scheduled five year review the RFMP was amended to reflect the changes in the environment. We are currently monitoring ecological recovery and fuel-load response. Data collected during these processes will be used to support a comprehensive review of proposed treatments. This review will be undertaken prior to the 2024-28 period. 

<strong>Bushfire management in the ACT</strong>

Bushfires are an inevitable part of living in the ACT. Canberra is described as the bush capital for good reason, with forest and grassland woven through its urban areas. Along with the rural areas and the mountainous and forested landscape to the west and south, living in the ACT means we live in or near an environment where bushfire is a natural occurrence.

State-of-Knowledge data quality ratings for Australian Marine Parks [Seamap Australia]

An assessment was made of the state of research knowledge in the Australian Marine Parks (2022 boundaries). This quality assessment is specifically of the suitability of data streams for deriving habitat maps.

Five nationally-aggregated data streams were used in the assessment:
(1) Seamap Australia (seafloor habitat)
(2) AusSeabed bathymetry survey extents (bathymetry mapping)
(3) Squidle+ imagery deployments (habitat observations)
(4) GlobalArchive video deployments (habitat observations)
(5) Geoscience Australia's Marine Sediment Database (MARS)

From these data streams, quality ratings (0-5) have been made for the state of research knowledge for three research disciplines:
(A) bathymetry maps;
(B) habitat observations; and
(C) habitat maps.

Data quality assessments are reported for each AMP Network and Park. Assessments can be accessed in context at https://seamapaustralia.org/region-reports, via the State-of-Knowledge functionality in the Seamap Australia mapping portal: https://seamapaustralia.org/map, or as a stand-alone file in the 'Downloads' section of this record. This data is live and is refreshed weekly.

Redmap (South Australia) - 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 see Point of Contact.
