Induced polarization effects in fixed-wing airborne EM: the TEMPEST™ system—Part B, field data inversion from regional targeting to deposit-scale characterization

This paper is the second part of a series examining the effects of ground polarization in airborne electromagnetic (AEM) data collected with fixed-wing platforms. Induced polarization (IP) effects can be detected using airborne electromagnetic methods; however, most geophysical studies have focused on helicopter-borne systems whose sensitivity to subsurface polarizable features is well established. In contrast, the potential of fixed-wing AEM systems for IP detection remains largely unexplored, and their effects have not yet been modelled. Building on Part A of this series, which examined the sensitivity of TEMPEST™ system to ground chargeability with numerical analysis and dataspace inspection, we extend the study using field survey data to model subsurface IP effects in inversion. This study is defined at three different exploration scales: deposit scale, survey-line and regional scale. The first experiment focuses on a comparative modelling analysis between the TEMPEST™ and SkyTEM312FAST helicopter-borne system along two overlapping survey lines. The results show highly comparable chargeability and resistivity distributions, with consistent outcomes across the TEMPEST™ measured components (X and Z) and with geological interpretation of the area. These findings demonstrate that fixed-wing AEM can effectively resolve IP anomalies with resolution and depth penetration similar to helicopter-borne systems, despite differences in acquisition geometry and system design. Then, to assess regional-scale applicability, the entire Musgrave Province in South Australia was inverted incorporating IP effects and comparing the results with the non-IP modelling of the area. The IP modelling show a systematically reduction of inversion misfit, when compared with non-AIP modelling with differences between the resistivity models higher than 100 per cent. To conclude, the ground truthing of regional modelling has been carried over the well-characterized Nemo-Babel mineralization. This confirmed that TEMPEST™ derived chargeability anomalies align closely with known mineralized zones, validating both spatial accuracy and correspondence with mineralization of the modelled resistivity and chargeability. Overall, this study demonstrates that fixed-wing AEM platforms, such as TEMPEST™, can detect and quantify ground chargeability from regional to deposit scale, providing a valuable tool to target exploration and to characterize mineralized bodies.

AGSO Cruise 125 Report : Tasmante Swath-mapping and Reflection Seismic Cruise off Tasmania using R.V. L'Atalante

The Tasmante cruise (AGSO Cruise 125) started in Auckland on 12 February 1994, and ended in Adelaide on 29 March 1994 (Fig. 1). The cruise used the French research vessel l'Atalante on an exchange basis. The French vessel was used rather than Rig Seismic because of the wide-angleswath-mapping capability of its SIMRAD EM12D system. Data were recorded on transits, as well as off Tasmania, our main area of interest (Figs. 1 &amp; 2). The swath-mapping system functioned well throughout. The maps produced are mostly at 1:250 000 scale, and cover the transit from New Zealand (T1-77), the detailed survey off Tasmania (C1-C7), and the transit to Adelaide (T8-T9). The suite of maps generally includes ship tracks, sonar imagery, detailed and less detailed contour maps (25 and 50 m contours), and an overlay of sonar imagery on the less detailed contours. In addition, 1:1 000 000 scale maps of the entire Tasmanian survey area were produced of bathymetry (50 m contours) and imagery. Finally, 1:100 000 scale maps were provided of two fisheries areas off Tasmania: 20 m contours and imagery in thesouth, and 20 m contours in the west.

South Australia Gravity Survey

<b>Survey Purpose:</b>
The Greater Adelaide airborne gravimetric survey was conducted to acquire high‑resolution gravity data for integration with existing terrestrial gravity observations. These data support the computation and refinement of the Australian Gravimetric Quasigeoid (AGQG) through the provision of new, high‑quality gravity measurements that improve spatial data coverage and resolution in the Greater Adelaide region.

<b>Survey Overview:</b>
The Greater Adelaide airborne gravimetric survey was conducted by Sander Geophysics Limited (SGL) for Geoscience Australia between 24 October and 14 November 2024. The survey acquired high‑resolution airborne gravity data over metropolitan Adelaide, surrounding mainland areas, parts of Kangaroo Island, Lake Alexandrina, and adjacent offshore regions.

<b>Survey Operations:</b>
Survey operations were based at Goolwa, South Australia, and covered varied terrain including the Adelaide Hills, agricultural lowlands, and coastal and offshore areas. Data were collected using a fixed‑wing aircraft equipped with a high‑resolution airborne gravimeter, differential GPS, barometric and radar altimeters, a laser rangefinder, and auxiliary sensors. Pre‑planned drape surfaces derived from Copernicus GLO‑30 DEM data were used to maintain a target terrain clearance of 160 m. The flight‑line spacing was 5,000 m, and the total distance flown was 10,350 km.

RV Investigator Voyage IN2026_V01 CTD Data

This record describes the CTD data collected on Investigator voyage IN2026_V01, titled: "Cook Ice Ecosystems and Sediments (COOKIES)." The voyage took place between January 02, 2026 and February 25, 2026 (AEST), departing from Hobart and returning to Hobart.

Data for 37 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #24, fitted with 36 twelve-litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.

37 CTD casts were performed. A Benthic CTD camera was attached to the CTD to observe seafloor approximately ~4 m off bottom. Waiting 20 seconds after camera before firing bottom bottles as they use the same channels.

Cast summary:
• #1 – primary sensor channel had blockage, cleared ¾ on way down
• #2 – primary sensor blockage on way down
• #21, 22, 23 – yoyo casts to 600m – No bottles fired

The final conductivity calibration was based on a single deployment grouping. There were no changes to the sensors used throughout the voyage. The final calibration from the secondary sensor had a standard deviation (SD) of 0.00128 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the secondary sensors.

The dissolved oxygen data calibration fit had a SD of 0.8692μM. The agreement between the CTD and bottle data was good.
PAR, CDOM, transmissometer, Chlorophyll-A, and Backscatter sensors were also installed on the auxiliary A/D channels of the CTD.
The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.

NESP MaC Project 1.24 - A pilot study into the movement and dispersal of sawfishes, 2021-2022 (MU)

This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "A pilot study into the movement and dispersal of sawfishes". For specific data outputs from this project, please see child records associated with this metadata.

The aim of this project is to test the utility of satellite telemetry to elucidate the movement and dispersal in large sub-adult and adult sawfishes, which are a poorly understood life-history phase of this globally and nationally endangered group. In 2021, research and monitoring surveys carried out by DPIRD (Fisheries WA) will provide a unique opportunity to access larger size classes of sawfishes in northern Western Australia. This project seeks to use this opportunity to generate a preliminary dataset on the suitability of satellite telemetry approaches that will guide future research on this taxon to inform the recovery plan.

Planned Outputs
 • Raw survey dataset
 • Animal tag gps tracking data
 • Tissue Sample
 • Final technical report with analysed data and a short summary of recommendations for policy makers of key findings [written]
