Marine Futures Project - Geographe Bay - 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 Geographe Bay in the southwest Capes region. The marine environment at this location varies from extensive seagrass meadows in protected waters, to kelp-dominated granite and limestone reefs in areas of high wave energy. A small number of corals are also found throughout the region, reflecting the influence of the southward flow of the Leeuwin Current. The fish fauna is also diverse, with a high proportion of endemic species.

Designing monitoring programmes for Marine Protected Areas within an Evidence Based Decision Making paradigm

The Evidence Based Decision Making (EBDM) paradigm encourages managers to base their decisions on the strongest available evidence, but it has been criticized for placing too much emphasis on the choice of study design method without considering the types of questions that are being addressed as well as other relevant factors such as how well a study is implemented. Here we review the objectives of Australia’s Marine Park network, and identify the types of questions and data analysis that would address these objectives. Critically, we consider how the design of a monitoring program influences our ability to adequately answer these questions, using the strength of evidence hierarchy from the EBDM paradigm to assess the adequacy of different design strategies and other sources of information. It is important for conservation managers to recognize that the types of questions monitoring programs are able to answer depends on how they are designed and how the collected data are analyzed. The socio-political process that dictates where protected areas are placed typically excludes the strongest types of evidence, Random Controlled Trials (RCTs), for certain questions. Evidence bases that are stronger than ones commonly employed to date, however, could be used to provide a causal inference, including for those questions where RCTs are excluded, but only if appropriate designs such as cohort or case-control studies are used, and supported where relevant by appropriate sample frames. Randomized, spatially balanced sampling, together with careful selection of control sites, and more extensive use of propensity scores and structured elicitation of expert judgment, are also practical ways to improve the evidence base for answering the questions that underlie marine park objectives and motivate long-term monitoring programs.

WITHDRAWN: eReefs GBR1 biogeochemistry and sediments v3.2

<strong><em>This dataset was retired by its authors in February 2026 because the model used to generate it was discovered to have an error which lead to abnormally high/unrealistic Chlorophyll-a levels on the shelf edge and reef matrix. The values in the results dataset are not only inconsistent with the more recent GBR4_H4p0_ABARRAr2_OBRAN2020_FG2Gv3_B4p2_Cq5b_Dhnd dataset, but also scientifically unreasonable for these areas, where Chla should generally be ≤0.5 mg m⁻³ based on coral sea observations. Researchers should discontinue any use of this dataset as soon as possible.</em></strong>

Results from version 3.2 of the 1km-resolution regional-scale biogeochemistry and sediments model of the Great Barrier Reef (GBR1), forced by version 2.0 of the 1km-resolution hydrodynamic model and with Furnas relationships for wet and dry tropics rivers as catchment inputs.

This model configuration and associated results dataset may be referred to as "GBR1_H2p0_B3p2_Cfur_Dnrt" according to the eReefs biogeochemical simulation naming protocol.

The model ran in near-real-time mode, updating daily, until January 2024 when the 2023/24 monsoon season caused damage to sensors in the catchments, and we lost access to the critical river-flow forcing dataset.

National Seafloor GeoMorphology (NSGM) mapping workshop

Geoscience Australia is leading the development of a scheme to map and classify seabed morphology and geomorphology at multiple spatial scales, for use by a range of disciplines and end-users. Central to the effort is the development of a consistent vocabulary and mapping standard, which is now in draft form as the National Seafloor GeoMorphology (NSGM) mapping scheme.

On 29th October 2018 a National Seafloor Geomorphology workshop was held at Geoscience Australia. The workshop was attended by representatives from Commonwealth and State agencies, industry and universities, and had the following objectives:
<ol>
<li>Engage with marine geoscience practitioners: we are seeking feedback and input on the science of the draft NSGM</li>
<li>Engage with state agencies: determine how to connect the draft NSGM scheme to the coast (intertidal and shallow subtidal)</li>
<li>Reach agreement towards the creation of a standard scheme for seafloor geomorphology mapping in Australia.</li>
</ol>

Coastal and marine researchers and practitioners in sedimentology, geomorphology and ecology, and state and Parks Australia representatives presented their own approaches to mapping the seafloor. Participants also commented on the translation of their own schemes to the draft NSGM scheme, and on the structure and breadth of the NSGM scheme. This feedback and other discussion points are represented later in this summary.

RV Investigator Voyage IN2021_E02 EM710 MKII Multibeam Echosounder Data

This record describes multibeam echosounder data collected on RV Investigator voyage IN2021_E02, to calibrate and commission new, upgraded and existing critical equipment (with sea trials and personnel training) onboard RV Investigator for upcoming voyages in the 2021 schedule and beyond. The primary objectives for this voyage were testing the Deep Corer winch stream and respool, Trawling winch calibration, CTD winch 1 &amp; 2 calibrations, HOTS commissioning and Heave Compensation testing, and Deep Towed Camera trial and calibration. The voyage took place between November 20 and November 28, 2021, departing from Hobart (TAS) and returning to Hobart.

The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter around east of Tasmania and around Freycinet Marine Park.

The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 40 to 100 kHz.

Data are stored in <em>.all raw format for bathymetry and backscatter and </em>.wcd format for watercolumn backscatter at CSIRO. There are 32 files totalling 12.2 GB of raw data in this dataset and 30 files totalling 39.7 GB of watercolumn data.

Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position.

Tide corrections were applied to the processed data using RTK/GPS height and the EGM2008 geoid model in Caris. Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff format.

Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.

Extent and persistence of photic zone euxinia in Late Devonian seas – insights from the Canning Basin and implications for petroleum source rock formation

Late Devonian mass extinctions attributed to extensive anoxia and/or euxinia of the oceans are associated with widespread deposition of organic-rich shales. Also in the epeiric waters of the Canning Basin (Western Australia), photic zone euxinia (PZE) prevailed during the Givetian–Frasnian, with geochemical evidence for PZE on the northern (Lennard Shelf)–, and southern (Barbwire Terrace) margins of the Fitzroy Trough. On the Lennard Shelf, shales record episodic pulses of PZE associated with high algal activity due to enhanced nutrient supply, whereas a restricted marine setting on the Barbwire Terrace is thought to be the main driver for the development of persistent PZE and associated bacterial predominance. Structural evidence indicates that the Fitzroy Trough was a confined basin during the Late Devonian with the possibility of limited ocean circulation. Widespread PZE is expected to have developed in the poorly mixed water column, if the basin received sufficient nutrient supply for enhanced primary production.

Notwithstanding the presence of anoxia during deposition of potential source rocks, only two small Devonian-sourced oil fields and numerous oil shows have been found in the Canning Basin. Biomarker assemblages show that the oils produced from the Lennard Shelf fields (i.e. Blina-1, Blina-4 and Janpam North-1) have substantially different molecular compositions to the minor oil recovered from Mirbelia-1 on the Barbwire Terrace. A correlation was established between the Lennard Shelf oils and rock extracts from the Gogo Formation at Blina-1 and McWhae Ridge-1 based on their hopane, sterane and carotenoids abundances. A definitive source correlation was not obtained for the Mirbelia-1 oil, but it did show some genetic affinity to the Givetian–Frasnian extracts from the Barbwire Terrace, suggesting that local source rocks are developed in the region.

Sea-ice HI-Photogrammetry Cape Evans (SIHIPCE) 2023

Dataset collected at Cape Evans, Antarctica, November 2023 as part of a long-term NIWA benthic monitoring program under the Antarctica New Zealand event number K882A.

The dataset includes multiple sea-ice and seafloor hyperspectral imaging transects (10-40 meters long) coupled with normal red, green, and blue (RGB) imagery from a dual camera machine vision system.  The data were acquired using the remotely operated vehicle (ROV) HIcyBot system, funded by the Australian Centre for Excellence in Antarctic Research (ACEAS).  A GNSS-integrated USBL transponder equipped onto the ROV allowed every frame of the high frequency hyperspectral imager to be timestamped via GPS clock to acoustically provided underwater position and attitude.

The dataset also includes hyperspectral imaging scans of sampled/retrieved organisms found at the seafloor, to support habitat mapping algorithm development (e.g., algae, urchins, sea-stars, etc.).  The ROV was tested as part of an ACEAS Program 2 subcomponent that involved the design of the new under-ice hyperspectral imaging and photogrammetric payload mounted onto the HIcyBot ROV.  The overarching goal of the systems was to be able to acquire information of under the sea-ice sympagic and benthic communities (e.g., biomass and photophysiology) and deliver a multi-scale array of biophysical data that can be assimilated with known information in the region and monitor fine-scale change.  Through the analysis of new and existing bio-optical under-ice data, the dataset aims to ultimately envisions the delivery of new monitoring tools and algorithms that can provide support for modelling efforts and reveal complex biophysical processes under a changing Antarctic Sea ice.

Crustal Transects of the Great Australian Bight : A Cruise Proposal in Support of the Ocean Drilling Program and the Law of the Sea

The southern margin of Australia has long been considered an example of a classic passive rifted continental margin. In recent times, it has been cited as an example of a 'lower plate' margin in the terminology describing detachment models of passive margin formation.However, despite extensive study by both industry and government since the early 1970s, some fundamental aspects of the structure and geological history of the margin remain speculative.

It is proposed here to use the AGS0 research vessel Rig Seismic to acquire 4087 km of deep-seismic data (16 s record length) in the central Great Australian Bight (GAB) and across the continental margin south of Western Australia. The survey has three principal objectives:
1. To enhance understanding of the tectonic evolution / event history of the southern margin in support of DPIE' s Acreage Release Program and thus to encourage successfulpetroleum exploration.
<ol>
<li>

To provide the necessary framework data in support of a proposal submitted to the Ocean Drilling Program (ODP) for drilling in the GAB; and 
</li>
<li>

To provide data in the GAB that support Australia's claim to a Legal Continental Shelf beyond the 200 n.m. Exclusive Economic Zone (EEZ) as defmed under the 1982 UNConvention on the Law of the Sea (UNCLOS).
</li>
</ol>

The specific scientific aims of the work include:
- Definition of the deep crustal structure of the region and the mode of margin formationacross a number of key transects. In particular, to image the key detachment surfaces which are believed to have controlled the extensional processes. Interpretation of the deepstructures will be enhanced by seismic refraction data recorded by Lamont-Doherty Geological Observatory in 1976 (Talwani et al., 1979).
<ul>
<li>

Determination of the location and structural setting of the continent-ocean boundary. In places, stratified tilt-blocks that lie oceanwards of the magnetically determined COBsuggest that either the COB identification is incorrect, old oceanic crust has been re-rifted, or the seismic data are imaging an amalgam of oceanic crust and continental slivers.
</li>
<li>

Determination of the structure and origin of the enigmatic Diamantina Zone, west of the GAB, and its relationship, if any, to the change in seafloor spreading rate at 44 Ma. Is the crust to the north oceanic, or is it highly extended continental?
</li>
</ul>

The marine geological imprint of Antarctic ice shelves

Widespread reductions in the thickness and extent of Antarctic ice shelves are triggering retreat, acceleration and increased discharge of marine-terminating glaciers. However, while the impacts of recent ice-shelf changes are now well documented, their role in modulating past ice sheet dynamics – especially at a resolution required to identify drivers of change and test ice sheet models - remains poorly constrained. This reflects two persistent issues: (i) the effective discrimination between sediments and landforms deposited in a sub-ice-shelf setting from other glacimarine environments, and (ii) challenges associated with dating these records. Here we summarise recent progress in deciphering the ‘geological imprint’ of Antarctic ice shelves, including important advances in dating methods and the proxies required to reconstruct the drivers of change. Despite this improved ‘toolbox’ for establishing ice shelf presence and absence, we recognise several challenges that need to be overcome if we are to fully exploit the palaeo record.

2019-20 Honours project - Sea level fingerprints associated with future land ice melting

We utilize the sea level fingerprint module - ISSM’s Solid Earth and Sea level Adjustment Workbench (ISSM-SESAW), developed by NASA/Jet Propulsion Laboratory (JPL), to provide high-resolution sea level fingerprints in response to future polar ice sheet mass changes in the 21st century under the Representative Concentration Pathway (RCP) 4.5 and 8.5 scenarios. We also explore the sensitivity of sea level fingerprints to different 1-D elastic Earth models and the spatial resolution at which mass change of polar ice sheets is resolved. Furthermore, sea level contributions by individual polar ice sheet basins in the 21st century are also estimated for some coastal cities of interest (e.g., Perth) in this research.
