Pacific inflow into South China Sea related to post-rift opening of Luzon gateway: consequences for the East Asian monsoon

The South China Sea (SCS) is the most important source of water vapor for the East Asian monsoon (EAM). Late Cenozoic (~34–30 Ma) opening of the SCS likely contributed significantly to the establishment of a strong, modern-like EAM at ~25 Ma per climate sensitivity studies. However, the importance of SCS tectonics in contributing to the evolution of the EAM has been neglected due to the temporal mismatch between both events (5–9 million years). Here, we investigate the bathymetric, sedimentary and oceanographic evolution of the SCS basin by combining Sr-Nd isotopic analyses of rift- to drift sediments from recent ocean drilling expeditions, high-resolution paleobathymetry reconstructions and ocean circulation simulations of this crucial time period. We show that the transition from fluvial, to shallow- and deep-marine environment in the SCS and its opening to the Pacific Ocean occurred well after the onset of seafloor spreading. We highlight a rapid (&lt;1 myr), “flooding” event of Pacific bottom waters entering the young SCS through the narrow Luzon Strait between 25.5–24.5 Ma, coinciding with the strengthening EAM pattern. This shift is underscored by isotopic analysis of detrital fractions which suggest a change in provenance from local sources to inland China deserts and Loess signal shortly before ~25.5 Ma, likely transported as eolian dust by intensifying winter monsoon winds. Tectonic-driven rapid Pacific flooding likely increased the east-west humidity gradient between land and sea and contributed to the establishment of a modern-like, strong EAM at 25 Ma.

ISOMOVE: Antarctic fur seal stable isotopes and tracking data

This dataset contains stable isotope and tracking data from adult female Antarctic fur seal collected at three breeding colonies across the Southern Ocean:

• Marion Island (2008–2018)
• Bird Island, South Georgia (2008–2012)
• Cape Shirreff, South Shetland Islands (2008–2012)

The dataset includes:
• Stable isotope data from whole blood and whiskers
• Compound-specific amino acid isotope data (δ¹⁵NAA) from whole blood
• GLS-derived tracking and environmental data

Samples were collected from adult female seals captured between February and April prior to winter migration. Whole blood samples provide dietary information integrated over approximately 2–3 months, while sequential whisker sections provide longer-term isotopic records spanning multiple years.

Bulk stable isotope values (δ¹³C and δ¹⁵N) and compound-specific isotope analysis of amino acids (CSIA-AA) provide information on trophic ecology and foraging habitat across multiple temporal scales, from recent feeding behaviour to multi-year dietary histories recorded in whiskers.

The dataset also includes light-based geolocation (GLS) tracking data from adult females equipped with geolocator loggers during the inter-breeding migration period. Tracking variables include timestamps (GMT), estimated geographic positions (latitude and longitude), uncertainty metrics, and associated environmental variables such as sea surface temperature (SST) and absolute dynamic topography (ADT), where available.

Cumulative sound exposure from shipping in the Australian EEZ

Over the past century there have been significant global increases in anthropogenic underwater noise from a range of sources, such as commercial shipping, oil and gas exploration, recreational and military sound sources. Anthropogenic noise has been demonstrated to impact marine animals, in particular marine mammals that rely on sound for communication, foraging, and navigation. Sound exposure may impair hearing mechanisms temporarily or permanently, with impacts ranging from temporary behavioural responses and stress, to longer term habitat avoidance, hearing loss, or mortality. 

Commercial shipping is thought to contribute to a significant portion of the underwater noise generated by human activity, driven by marine transport network expansion, urbanization, and greater demand for natural resources. This project aimed to quantify underwater noise from ships in Australian waters, with the ultimate goal of guiding the management of noise impacts on marine fauna. This record describes a gridded map of cumulative sound exposure from shipping in the Australian EEZ for a typical April-September period.

NESP MaC Project 5.15 - National assessment of harmful algal bloom preparedness and future needs (UTS)

This record provides an overview of the NESP Marine and Coastal Hub Emerging Priorities project "National assessment of harmful algal bloom preparedness and future needs". No data outputs are planned for this project.

The 2025 South Australian harmful algal bloom (HAB) highlighted major gaps in Australia’s preparedness for large-scale marine HAB events, including limitations in surveillance capability, forecasting systems, coordination arrangements and long-term response planning. While HABs are not new to Australia, the scale, duration and ecological impacts of the South Australian event demonstrated the need for a broader national assessment of HAB science capability and policy readiness.

This project will review Australia’s current capability for HAB surveillance, forecasting, response and management across environmental and seafood-safety domains. It will examine existing monitoring systems, research capability, early-warning approaches, coordination arrangements and operational policy settings across Commonwealth, state and territory jurisdictions.

The review will consider lessons from the South Australian bloom alongside national and international approaches to HAB preparedness and management, including monitoring technologies, forecasting systems and risk mitigation strategies. It will also consider relevant recommendations from the Australian Senate inquiry into the South Australian algal bloom and broader national policy frameworks, including the draft Sustainable Ocean Plan.

Project outputs will include an assessment of current national HAB capability, identification of critical knowledge and operational gaps, and recommendations for improving HAB preparedness, surveillance, forecasting, coordination and response capacity in Australia.

Tasmanian Fisheries and Aquaculture Industry Economic Contributions 2022/23

This report presents the economic contribution of seven (7) key fisheries and aquaculture sectors, inclusive of processing, to the Tasmanian economy for the 2022/23 financial year:
-   Tasmanian Rock Lobster Fishery;
-   Tasmanian Dive Sector (Abalone Fishery, Commercial Dive Fishery);
-   Tasmanian Scalefish Fishery;
-   Tasmanian Salmonid Aquaculture;
-   Tasmanian Pacific Oyster Aquaculture; and
-   Tasmanian Abalone Aquaculture.

It also reports previously published contributions for six (6) fisheries and aquaculture sectors (Tasmanian Rock Lobster Fishery; Tasmanian Abalone Fishery; Tasmanian Scalefish Fishery; Tasmanian Salmonid Aquaculture; Tasmanian Pacific Oyster Aquaculture; and Tasmanian Abalone Aquaculture), exclusive of processing, to the Tasmanian economy for the 2020/21 and 2018/19 financial years:

The economic contribution of these fisheries and aquaculture sectors are measured through the following indicators:
-   Gross Value Added (GVA)
-   Contribution to Household Income
-   Number of persons employed
-   Contribution to the total full-time equivalent (FTE) workforce

The work was undertaken by the Institute for Marine and Antarctic Studies at the University of Tasmania in collaboration with BDO and builds on the foundations and approach set out in 2017/18 National Fisheries and Aquaculture Industry Contributions Study (FRDC 2017-210). To generate the values for the indicators listed above, the framework recommended in Australian Fisheries and Aquaculture Industry: Economic Contributions Estimates - Practitioner Guidelines 2019 (IMAS 2020) was applied. For the analysis in this report, the contribution of immediate processing or farm gate retail activity is not included. The estimates are based on the best available information at the time of writing and apply input-output modelling (developed by BDO) that uses the economic profiles and conversion to basic prices as provided by IMAS.

The study was conducted to contribute to the measuring and monitoring of the contribution of Tasmania’s seafood production activities to the economic prosperity and wellbeing of Tasmanians. This dataset includes the economic contribution of seafood processing for the 2022/23 year.

Area-based Australian Carbon Credit Unit (ACCU) Scheme projects

This dataset identifies the project boundaries for registered Australian Carbon Credit Unit (ACCU) Scheme area based projects. Area based projects are generally savanna burning and sequestration activities.

These ACCU Scheme projects are registered across a declared project area identified by project proponents at the time of registration. These project areas generally encompass the entire cadastral boundaries for the properties for which the participants intend to conduct their project activities and for which they hold legal right.

For sequestration projects the project area does not generally represent the actual extent of a project activity which is generally a subset of the project area. These subset areas are known as Carbon Estimation Areas (CEA) which are defined by rules set out in the individual ACCU Scheme methods. A project can contain one or many CEAs.

The dataset includes basic attribution including:
Scheme Participant;
Project Name;
Project ID;
Method;
Method Type;
Project Description;
Date Project Registered;
Project location (State);
Project location (Postcode);
Permanence Period; 
Project Status (Active or Revoked); and,

The Clean Energy Regulator publishes and maintains a project register which contains further details about projects registered under the Emissions Reduction Fund. The project register is published on the Clean Energy Regulator website at https://cer.gov.au/markets/reports-and-data/accu-project-and-contract-register?view=Projects and is the point of truth for information about ACCU Scheme projects.

The project register contains attributes not in the spatial dataset, such as, the number of Australian carbon credit units (ACCUs) issued, whether any units have been relinquished, or if that land has a carbon maintenance obligation in place. However, the Project Id attribute (PROJ_ID) can be used to link the mapping data with the project register if analysis of those attributes is required.

Notes:

1. Users should be aware that the project register is updated on a monthly basis.

2. The dataset does not contain the boundaries of ten projects which have had their location suppressed or partially suppressed.

3. The dataset contains revoked projects. These are identified as being revoked in the status column

NESP MaC Project 1.11 - OzSET: Integration and publication of the Australian Surface Elevation Table dataset, 2021-2022 (Macquarie Uni, UQ)

This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "OzSET: Integration and publication of the Australian Surface Elevation Table dataset". For specific data outputs from this project, please see child records associated with this metadata.

Australia’s coastal floodplains and wetlands provide essential ecosystem services and have immense cultural value. They regulate water quality, moderate flood and storm damage, and provide habitat for marine life including commercial fish and shellfish species. These environments are threatened by accelerating rates of sea-level rise. A national approach is needed to monitor and assess the way coastal floodplains and wetlands are changing in response to sea level rise.

A useful measure of resilience is the extent to which coastal wetland sediments can accrete vertically at a rate matching that of sea-level rise. Assessing the resilience, or vulnerability, of these environments requires measurements of rates of vertical accretion, subsidence and elevation gain across a range of coastal settings. The Surface Elevation Table-Marker Horizon (SET-MH) technique measures the vertical accretion of coastal wetland sediments. This enables assessment of whether wetlands are keeping pace with sea level rise (measured at tide gauges), or subsiding relative to local sea level rise and thus vulnerable to permanent inundation and loss. 

Australia’s network of Surface Elevation Tables is one of the most extensive in the world, consisting of over 200 benchmark monitoring stations from Westernport Bay, Victoria to Darwin Harbour, NT. The network has developed largely without national coordination, and the data gathered have not been readily available to the research community or research users.

This project collated SET data on accretion, subsidence and elevation change in mangroves, saltmarshes, seagrasses and tidal freshwater forests, and provides an initial analysis of accretion and surface elevation trends. This information is vital to coastal risk assessment, estimating blue carbon sequestration, and modelling potential predicted changes in other ecosystem services.

NESP MaC Project 2.6 - Mapping critical Australian sea lion habitat to assess ecological value and risks to population recovery, 2022-2024 (SARDI)

This record provides an overview of the NESP Marine and Coastal Hub project "Mapping critical Australian sea lion habitat to assess ecological value and risks to population recovery". For specific data outputs from this project, please see child records associated with this metadata.

Australian sea lion populations have declined by more than 60% over the past four decades. Abundance and trends vary markedly across the species range, suggesting that localised risk profiles from threats - such as bycatch, marine pollution, and habitat degradation - vary at small spatial scales. Fine scale variation in habitat use is thought to underpin these differences, yet knowledge about Australian sea lion's dependency on key habitats and their vulnerability to human impacts is limited.

This project deployed compact animal-borne cameras with GPS and motion sensors on eight adult female sea lions at two key colonies: Seal Bay (Southern Kangaroo Island Marine Park) and Olive Island (Western Eyre Marine Park). The devices recorded nearly 80 hours of footage over 560 km of seabed, identifying six distinct benthic habitat types, including previously unmapped rocky reefs and kelp forests.

The footage was used to develop fine-scale habitat maps using machine learning models, providing a valuable baseline for assessing ecological value, foraging intensity, and the effectiveness of protected areas. This innovative approach complements traditional seafloor mapping and offers a scalable, cost-effective method for locating and monitoring critical habitats for endangered marine species.

The results directly inform recovery planning, fisheries management, marine park design, and the identification of Biologically Important Areas. Ongoing camera deployments at Seal Bay and new sites along the western Eyre Peninsula will improve understanding of sea lion colony-specific behaviours and contribute to long-term monitoring of habitat change, diet, and emerging threats.

Outputs
• Tracking data from sea lion-deployed tags: location, depth, time, temperature, light, acceleration [dataset]
• Timestamped video footage from sea lion-deployed cameras [dataset]
• Final project report [written]

Abalone fishing block 22 - 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 <em>FISHING BLOCK 22</em>. 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 (23, 24, 27, 28, 29, 30).
