Gravity data acquired with SGL's AIRGrav system during the Operation IceBridge project have provided scientists with a new bathymetric model revealing important characteristics about the ice flow around Thwaites Glacier. While the glacier is pinned to the east on a prominent ridge, it lost contact to the west approximately 55 to 150 years ago, scientists have determined, based on current thinning. The gravity-derived bathymetric data have revealed an undulating offshore ridge that has been a hindrance to floating ice and the circulation of sea water, thus providing more stability to the Thwaites Glacier. Insight into the future retreat of the glacier has also been revealed by AIRGrav data.

The Gamburtsev Subglacial Mountains buried under the East Antarctic Ice Sheet have been a subject of great interest for researchers, who have had difficulty explaining their high elevation and youthful Alpine topography in spite of their considerable age. Data collected during the International Polar Year project of 1989-1990 to study Antarctica's Gamburtsev Province (AGAP) have revealed in-depth information about the crustal architecture and uplift mechanisms of these mountains, as reported in the journal Nature (see link below). Sander Geophysics participated in the AGAP project that led to solving this mystery, providing an AIRGrav system and personnel to acquire and process airborne gravity data under contract to Lamont-Doherty Earth Observatory (see 2009 news items below).

Sander Geophysics again returns to Antarctica with NASA's IceBridge project collecting data with its AIRGrav system. AIRGrav is one among a number of instruments that IceBridge utilizes in its airborne campaigns to measure the thickness of ice in Earth's polar regions. The use of the term "bridge" refers to the gathering of data using aircraft to fill the gap between NASA's now defunct Icesat laser altimeter spacecraft and the future Icesat-2 mission due to come into operation later this decade. Recently, NASA's Operation IceBridge flew a mission to gather more detailed data regarding the process of an iceberg calving, after satellite imagery showed a growing crack on the Pine Island Glacier in Antarctica in early October. The crack is almost 30 km (20 miles) across and 60 m (200 ft) deep and it is growing daily. Pine Island Glacier is one of the largest and fastest-moving tongues of ice, and NASA researchers' expect the eventual iceberg will be approximately 880 sq km in areal extent.

One of the reasons Sander Geophysics' AIRGrav (Airborne Inertially Referenced Gravimeter) is part of Operation IceBridge is that it compliments radar systems which are unable to penetrate liquid water. Gravity data can help determine bathymetry beneath floating ice, either offshore or onshore in sub-glacial lakes. This in turn enables the creation of water circulation models and thus helps to predict the melting of ice from underneath the ice sheet. A number of elements are required to gather accurate gravity data from a moving aircraft including very accurate acceleration sensors and GPS data.

NASA's IceBridge — Arctic 2011 has begun. Sander Geophysics is again involved in the project with its AIRGrav system. The AIRGrav system is well suited to the task as it measures density and can reveal the variation between water, ice and rock. Monitoring how the Arctic polar ice is changing including the depth of snow and sea ice provides a better understanding of the effects of climate change. Survey flights this spring will include trips from Thule, Greenland, over the north of Ellesmere Island, in Canada to Russian airspace and also north of Prudhoe Bay, Alaska.

Scientists working with data from Antarctica's Gamburtsev Province Project (AGAP) have discovered that the liquid water locked underneath the continent´s coat of ice is thawing and refreezing to the bottom. Ice sheets build up from the top but scientists have known little about the processes underneath. In some places accumulation has been shown to be greater at the bottom than the top. These discoveries are part of understanding how the ice forms and deforms which is critical to comprehend its response to climate change. Sander Geophysics participated in AGAP in 2008-2009. This International Polar Year project involved flying at low-altitude in a grid pattern over the Antarctic ice sheet to determine what lay beneath and determine how the mountain peaks, ice sheet, and subglacial lakes interact with one another.

Scientists working on NASA´s Operation IceBridge data from 2009 have made a new discovery. A deepwater channel under the Pine Island Glacier was found through the mapping of water depth and seafloor topography. While laser and radar instruments can measure the elevation of the ice surface and the bedrock below they cannot penetrate the water. Sander Geophysics' AIRGrav allows ice, water and rock to be identified due to their difference in density. The thickness of these materials can then be estimated. This discovery may help to explain the nature of the recent changes in the glacier and thus be able to better predict the changes to come.

To demonstrate the capability of AIRGrav for marine gravity applications Sander Geophysics performed a marine gravity survey on Lake Ontario in October, 2009. Preliminary results from the survey are excellent, and the data will be publicly released once final processing has been completed. Sander Geophysics has been acquiring and processing high resolution airborne gravity data for over 10 years using the company´s 12 AIRGrav systems. AIRGrav is now the industry standard for high resolution airborne gravity, with over 2 million lkm of airborne gravity surveys flown worldwide. Designed specifically for the unique characteristics of the airborne environment, AIRGrav is the highest resolution gravimeter available. The data quality is not affected by the air turbulence normally encountered on airborne surveys, even in hot and windy environments. The stability of the AIRGrav system also allows surveys to be flown under normal daytime survey conditions. Until now AIRGrav has been used exclusively for airborne surveys, but AIRGrav´s ability to operate in the harsh airborne environment makes it ideally suited to marine use, where it can be used in conjunction with seismic or as a standalone survey - AIRGrav is essentially over-engineered for the less harsh environment of marine surveys, where vibration and vessel acceleration is much lower than in an aircraft.

December 2003

Sander Geophysics has started flying an airborne gravity survey near Timmins, Ontario for Discover Abitibi. The survey is being flown with Sander Geophysics' proprietary AIRGrav system, and it is intended to aid in the mapping of regional geology within this important mining belt. The survey was originally planned as a ground survey, but SGL successfully demonstrated that a fixed-wing AIRGrav survey can match the accuracy and resolution of a ground gravity survey and can deliver significant cost and time savings. Additional information about the survey is available on the Discover Abitibi website.

October 2003

Sander Geophysics now has an aircraft in Brazil ready for surveying. With our Brazilian partner, AeroSat we have licensed and registered a specially modified geophysical aircraft for work in Brazil. The aircraft was brought from Canada and registered in Brazil, and now carries the registration PT-MGX. The aircraft is equipped to conduct airborne gravity, magnetic, and gamma ray spectrometer surveys. Airborne gravity surveys are conducted with SGL's proprietary AIRGrav system which is a purpose built airborne gravimeter. This system has flown gravity surveys in North and South America, Africa and the Middle East.

October 2003

SGL has recently acquired three new aircraft for geophysical surveying, including two fixed-wing aircraft and a helicopter. The company now has a total of ten modern survey aircraft, including six turbine engine Cessna 208B Grand Caravans and a Eurocopter AS 350 B3 helicopter. All SGL aircraft have been extensively modified to reduce their magnetic effect.

September 2003

SGL flew an AIRGrav test survey just north of the town of Timmins, which includes the airport and the Kidd Creek mine site. AIRGrav test survey data set is now available on the Discover Abitibi website or it can be obtained from SGL directly. The data set contains the AIRGrav data, ground gravity data and the survey report.

July 2003

SGL has recently completed and tested a second AIRGrav system. This system is a purpose built gravimeter designed for the rigors of the airborne environment, and suitable for fixed-wing or helicopter surveying. Fixed-wing AIRGrav surveys typically result in airborne gravity data with an accuracy of 0.2 mGal over a two kilometer half sine wave anomaly.
