304 to Yuma. SkyTEM technology maps groundwater in Arizona

SkyTEM survey USAThe SkyTEM304 airborne geophysical system will soon be mapping groundwater resources in Arizona.  The Bureau of Reclamation (BOR), Yuma, Arizona, manages groundwater commitments to critical water districts that use the Colorado River, Gila River, and Yuma area groundwater resources for irrigation and other agricultural activities. The Yuma Area is one of the most heavily-farmed areas in the United States and agriculture here accounts for an annual gross economic return of $3.2 billion. Crops are grown year-round and miles of water delivery infrastructure ensures the agricultural industry is successful. In order to better meet Arizona’s water commitments today and sustainably in the future the BOR is using the SkyTEM airborne geophysical method to characterization groundwater resources in the greater Yuma area.

Data from SkyTEM systems are used as input by scientific organizations and governments worldwide to help them better understand and manage groundwater resources. The team assembled for this project consists of Southern Helicopters, XRIBlue, AlliedGIS and SkyTEM.  XRIBlue, a water exploration and production company has teamed with Allied GIS to process and deliver data that includes detailed geological cross sections and 3D imagery from the very near surface to depths over 350 m. Southern Helicopters, with several years of experience flying SkyTEM systems, will provide the helicopter and pilot. Data acquisition is expected to take place throughout September.

Bureau of Reclamation begins low-level helicopter research flights over Yuma area

YUMA, Ariz. — Reclamation’s Yuma Area Office (YAO), in accordance with Federal Aviation Administration regulations, is announcing an upcoming research project involving low-level helicopter flights in the Yuma area. The helicopter will be towing a large hexagonal frame over the Yuma agricultural production areas and the Colorado River over the next few weeks to survey and capture groundwater imagery. The flights will begin the last week of August and continue for up to 3 weeks.

On August 8, 2016 YAO entered into a contract with SkyTEM to collect real-time airborne electromagnetic geophysical survey flow imagery to determine the amount, location, quality and breadth of groundwater existing in underground channels and aquifers in the area. The instrumentation mounted below the helicopter gathers geologic measurements to learn more about water quality and the extent of aquifers existing below the sub-surface layer.

As part of the research effort, the contract helicopter will fly repetitive survey and grid runs over the Yuma Mesa, Yuma Irrigation District, Gila River, Wellton Mohawk, and along the southerly border with Mexico.

As part of its primary mission, YAO monitors and manages the depth and concentration of groundwater levels in the Yuma area for the use and benefit of water districts who depend on these supplies from the Colorado and Gila Rivers for irrigation, municipal use, or other related purposes. To better meet current and future water use needs in the area, YAO is undertaking a groundwater resource characterization study throughout the greater Yuma vicinity.

In conducting the detailed research, technicians will affix electromagnetic based survey equipment to a hexagon-shaped support apparatus that is towed about 100 feet below the helicopter in a ‘spider web’ array that is designed to map geologic features beneath the earth. The helicopter will be staffed by experienced pilots specially trained for low-level flights using this type of equipment.

Data gathered from the research flights will help YAO better understand and manage groundwater resources, and will include detailed geological cross sections and 3D imagery from the very near surface to depths over 350 meters. Data acquisition is expected to take place throughout September.

ENWRA continues to employ SkyTEM method to map aquifers

SkyTEM is happy to announce that we are again working with Eastern Nebraska Water Resources Assessment (ENWRA) in their multi-year programme to map groundwater resources in the State.  Several Natural Resource Districts (NRDs) have joined together to take advantage of the SkyTEM system and each has planned a mix of survey goals. SkyTEM is a helicopter-borne geophysical system capable of mapping subtle changes in geology from the very near surface to depths over 500 m.

See www.enwra.org for a map of the areas being studies as well as to download ENWRA – Introduction to a Hydrogeological Study for details on ENWRA’s projects and goals and approach to groundwater management.

ENWRA

In 2006 the NRDs determined that careful management of all aquifers, even those not directly connected to surface water, are important because the localized and hydrogeologically-complex nature of many aquifers in eastern Nebraska makes them susceptible to overdevelopment and depletion. The ultimate goal of ENWRA is to develop a three-dimensional geologic framework for all of eastern that can be used to determine location, depth to and volume of aquifers. ENWRA worked with the U.S. Geological Survey to assess geophysical tools for their applicability in mapping buried aquifers under deep layers of glacial till as found in parts of Nebraska. SkyTEM is pleased to have been selected for this year’s projects, and for all the previous years ENWRA has employed our unique technology.

The SkyTEM method, specifically developed to map buried aquifers, is widely accepted globally as the principal technique for mapping water resources. SkyTEM is an innovative and technologically advanced airborne geophysical system capable of mapping the top 500 metres of the Earth in fine detail and in 3 dimensions. It was conceived and engineered in Denmark, a country with a reputation for environmental care and R&D. SkyTEM has helped geological organizations and government water agencies on seven continents unearth a wealth of information about their aquifers and aided in their understanding of how geology and mankind can affect, and be affected by, groundwater resources. The SkyTEM method has mapped water resources on a Galapagos Island, important agricultural areas in the USA, Australia, Africa and India, islands in the Caribbean and Indian Ocean and even Antarctica. Recognized for its ability to quickly and accurately map geology in fine detail, the SkyTEM method is also employed globally for mineral and oil & gas exploration as well as environmental and engineering investigations.

Danish water technology in White House summit

SkyTEM Waterville

On 22 March Barack Obama invited to the summit “Moonshot for Water” in connection with the World Water Day in the White House, Washington DC. The participants were more than 200 decision-makers from the President’s office, federal, state and local offices as well as NGOs and Universities.

The US is facing challenges on drought and unnecessary water of water resources. Over the years to come, billion-dollar investments will have to be made to reduce the Americans’ water and energy consumption. Together with a handful of Danish water technology businesses, the SkyTEM technology was part of a consortium of Danish water expertise.

The solutions were presented in a Lego model of a town named Waterville built of 20,000 Lego blocks with a 1.5m tall skyscraper, water supply, wastewater treatment plan and a SkyTEM frame hooked under a hoovering helicopter.

SkyTEM improves chances of finding water in drought stricken California

SkyTEM mapping water in California

SkyTEM began mapping aquifers in the Central Valley of California as well as Barstow area earlier this year. The SkyTEM508 system has now returned to continue mapping farm lands in the Central Valley.

A recent groundwater mapping project in Australia showed that drilling alone is a hit-and-miss technique in which there is just a one-in-five chance of finding water and even less chance of finding water of suitable quality. SkyTEM’s accurate high resolution data has been used to improve the success rate to better than 1 in 3.

Combined with our ability to detect subtle geological contrasts in the top 400 m, at 150 kilometres per hour, this technology is of significant value to the global mineral and oil & gas exploration communities as well.”

Contributing to the unprecedented SkyTEM data acquisition rate and quick completion of the project was the communications expertise of Mr. Reg Whiten, President of InterraPlan Inc., who worked closely with local First Nations, the SkyTEM field crew, Devbrio Géophysique Inc, who adjusted day to day flight plans to accommodate First Nations cultural events and hunting season requirements and the logistics support and skills of pilots from Bailey Helicopters Ltd.

Mr. Carlos Salas, Vice President, Energy at Geoscience BC said “the Peace Project has collected valuable information. Without the cooperation of everyone, especially the local community, the results would have been much different.”

Information from the Peace Project will serve as a key component of the Northeast Water Strategy by providing knowledge to enable the Strategy’s Enhanced Water Monitoring System. The Northeast Water Strategy is currently under development by the Provincial government with cooperation from Treaty 8 First Nations, local governments, regulatory bodies, and the resource sector.

SkyTEM appreciates the opportunity to map the earth’s critical resources and are proud to have played a role in this vital project.

Combined SkyTEM and AIRGrav Survey in Hope Bay, Nunavut

SkyTEM Nunavut

SkyTEM Canada Inc is pleased to report that data acquisition on TMAC Resources’ Hope Bay and Elu gold mining projects in Nunavut has begun. SkyTEM and Sander Geophysics have teamed to acquire over 15,000 line kilometres of combined electromagnetic, magnetic and gravity data over TMAC’s properties. The airborne data will be used to supplement previous exploration carried out on the Greenstone belt, helping TMAC create Canada’s next major gold mining camp.

The Hope Bay airborne exploration program includes:

  • A SkyTEM516 electromagnetic and magnetic survey over the Hope Bay and Elu properties. SkyTEM516, a dual moment system, is capable of delivering a dipole moment of more than 1,000,000 NIA. A uniquely engineered receiver design reduces the noise level by a factor of 20 for the collection of accurate high resolution data from the near surface to depths of several hundred metres. In early 2015 SkyTEM516 demonstrated its depth and resolution capabilities by mapping the deep and weakly contrasting Caber Deposit in Québec, Canada. Caber results can be seen here.
  • A Sander AIRGrav purpose built airborne gravimeter to acquire high resolution helicopter gravity data over the Elu North and South survey blocks. This unique gravimeter is mounted on a three-axis inertially stabilized platform, combined with extremely accurate Differential GPS (DGPS) to correct for aircraft movement and vibrations. AIRGrav offers a number of advantages over competing systems, including: 1) significantly better resolution and accuracy; 2) ability to operate under turbulent flying conditions; 3) ability to provide high quality gravity data while flying in drape mode; 4) significant operational efficiencies; and 5) shorter time required for data acquisition and processing.
  • 24/7 data acquisition. SkyTEM is managing the surveys and, together with Sander Geophysics and field crew from Devbrio Géophysique Inc, has mobilized a team of 7 professionals, including helicopter pilots, to Hope Bay to take advantage of available daylight hours in Nunavut and maximize daily data acquisition. TMAC’s infrastructure contributes to survey efficiency with the availability of three camps, air strips, roads, fuel storage, a port and power plants. Preliminary data and 1D EM inversions are being delivered every 48 hours throughout the project.

Along with Gravity/Mag/EM data, post processing of Airborne IP signatures will also be completed. If unique geophysical indicators can be defined for the various styles of mineralization at Hope Bay it will significantly improve future exploration targeting and reduce future exploration expenditures and timelines to success. SkyTEM and Sander are both proud to play a part in this important Canadian gold mining project.

SkyTEM data accuracy maps depth to and thickness of Nebraska aquifers

SkyTEM EM survey

In 2013 SkyTEM304 collected data over 99-square miles of Eastern Nebraska to provide critical information on the condition of aquifers in areas suffering from declining water levels.  According to management of the Lower Platte South Natural Resources District (LPS NRD) SkyTEM’s accurate high resolution results provide extensive information about the area’s geology, aquifer characteristics and water in storage.  The NRD’s use of the data is on-going.  The data is intended to help landowners in the project area access data showing the depth to aquifer material, the thickness of the aquifer and other basic information.  The information collected is also available for download and can be found here.
