Mapping Water Resources with Scientific Precision
From challenge to clarity in groundwater mapping
Mapping groundwater and aquifer resources
SkyTEM provides high-resolution data to identify aquifers and define geological boundaries. By differentiating water-bearing sands from impermeable clays, we help calculate storage capacity and locate high-yield paleochannels. This non-invasive approach supplements borehole data to deliver clear, large-scale resource assessments for sustainable water management.
Managing salinity and saltwater intrusion
We use advanced electromagnetic transmitters and sensors to detect and map saline water in coastal and agricultural areas. Because saltwater is highly conductive, SkyTEM effectively tracks salt-front migration and identifies areas at risk of intrusion. This data establishes critical baselines to monitor salinity changes, protect freshwater supplies, and help stakeholders implement mitigation.
Recharge sites and contaminant plumes
SkyTEM assists in locating optimal sites for Managed Aquifer Recharge (MAR) by identifying permeable zones that facilitate efficient water infiltration. Additionally, our surveys can track the movement of conductive contaminant plumes to protect surrounding groundwater resources. This proactive monitoring ensures both the efficiency of water storage and monitoring and identifying contaminants.
Comprehensive insight from the air
SkyTEM provides high-resolution airborne data that define the structure, depth, and quality of groundwater systems. Our calibrated surveys acquire thousands of data points every second, delivering consistent, reliable results across vast areas within days.
The result is a complete, data-driven foundation for confident and sustainable groundwater management.

The SkyTEM technology was chosen because it is particularly well suited for large-scale groundwater mapping. The system can rapidly acquire consistent electromagnetic and magnetic data while flying at low altitude, producing high-resolution images of the subsurface from near the surface down to several hundred meters in depth. Compared to conventional ground-based surveys, SkyTEM can cover large regions quickly and non-invasively, providing a continuous picture of aquifer systems that would otherwise require years of investigation. Based on the quality of the data, the technical expertise of the personnel involved throughout the survey, and their ability to manage unforeseen events, SkyTEM is highly recommended for organizations seeking to obtain the best possible subsurface information and confidently define drilling targets for effective and efficient exploitation of groundwater resources.
For over 15 years, SkyTEM has been our trusted partner in enabling the acquisition of high-quality, perfectly calibrated airborne electromagnetic data across France—from the mainland to our overseas departments and territories.
Throughout our long-standing collaboration, SkyTEM has consistently pushed the boundaries of innovation, continuously improving both depth of investigation and near-surface resolution. This cutting-edge data has proven invaluable for a diverse range of critical applications, including raw materials prospecting and landslide risk assessment. Crucially, their technology has revolutionized our hydrogeological knowledge. By mapping groundwater resources with incredible precision, SkyTEM provides the insights we need to support vital sustainability initiatives and secure water resilience in a changing climate.
Throughout the Brokilde project, SkyTEM demonstrated strong operational performance, effectively managing the logistical challenges of the Danish landscape while delivering high quality geophysical mapping. The SkyTEM Diamond system provided high-resolution data from the nearest surface (as shallow as 1 meter) down to depths of 200 meters, offering the necessary data for an update of the geological model in the catchment area at Brokilde. Combined with the professional delivery of digital datasets and reporting, SkyTEM and Ramboll have provided data for further analysis that are needed for renovating Brokilde well field.
We are pleased to acknowledge the exceptional contribution of SkyTEM Surveys ApS to our recent airborne electromagnetic (AEM) survey initiative in Maun, Botswana. Contracted by Kemcore Botswana (Proprietary) Limited, SkyTEM undertook an extensive survey comprising approximately 6,100 line kilometres, with a line spacing of 1,000 metres and detailed infill lines at 500 and 250 metres respectively.
SkyTEM’s operational efficiency and deep technical expertise were evident throughout the project, delivering highly accurate geophysical data that proved instrumental in mapping subsurface aquifers, including brine-rich formations. This work significantly supported our sustainable groundwater management efforts and informed strategic decisions in water sourcing and mineral extraction.SkyTEM’s professionalism and commitment to excellence make them a highly recommended partner for any geophysical exploration campaign.
In February 2021, SkyTEM Surveys ApS carried out a helicopter-borne EM/MAG geophysical survey near Ghanzi, Botswana, using their state-of-the-art SkyTEM312FAST system. The project comprised of 2,380 kilometres with ultra-precise 200-metre line spacing, this surveying mission targeted copper and silver deposits in the heart of the legendary Kalahari Copper Belt, reaching depths of up to 400 metres beneaththe surface.
From data acquisition to the production of maps and reports, every aspect of the SkyTEM survey was executed with outstanding safety and efficiency. The high-resolution SkyTEM312FAST data results not only lived up to expectations - it redefined them, confidently delineating our mineral targets.
SkyTEM Surveys ApS successfully completed a regional helicopter-borne electromagnetic (AEM) and magnetic geophysical survey over the Company’s tenement package near Ghanzi, Botswana. Despite exceptionally challenging conditions, including a record wet season and the impacts of COVID-19, SkyTEM delivered high-quality results with professionalism and resilience.
The project comprised 18,970 line kilometers using the advanced SkyTEM312FAST system and the survey objective was to map targeted copper/silver prospects across the Kalahari Copper Belt in Botswana ranging from surface to approximately ±400 metres. The scope of the work included acquisition, processing, and delivery of comprehensive datasets, reports, and maps.
