ASD is seeking and accepting submissions for the 5th annual Students in Mining & Energy TerraSpec® Instrument Program. The Students in Mining & Energy TerraSpec Instrument Program was established by ASD to enhance innovation in the mining industry through advances in mineral measurement analysis. ASD continues its tradition of challenging graduate students involved in mining, geology, energy or geothermal related research to submit their research projects for the 2018 calendar year.

The stability of the Greenland Ice Sheet (GrIS) in a warming world is a critical research area with societally important implications for future sea level rise, with projected GrIS sea level contributions of at least 20 cm by 21001,2. Previous studies conclude that GrIS mass loss has been accelerating over the past decade, but spatial and temporal variations in GrIS mass balance remain poorly understood due to a complex relationship among precipitation and temperature changes, surface melt, runoff, ice discharge3, and surface albedo4. Satellite measurements indicate that albedo, the proportion of incoming solar radiation that is reflected by the glacier surface, has been declining over the past decade5,6, but the cause of the GrIS albedo change remains poorly constrained by field data. As fresh snow (albedo > 0.85)7 warms and melts, its albedo decreases due to snow grain growth, promoting solar absorption, higher snowpack temperatures and further melt8. However, dark impurities like soot and dust can also significantly reduce snow albedo, even in the dry snow zone2.
ASD is now accepting submissions for the 11th annual Alexander Goetz Instrument Support Program. ASD continues its tradition of challenging graduate students from all fields of study involving remote sensing and field spectroscopy to submit their research projects for the 2018 calendar year.
Near-infrared (NIR) spectroscopy is and has been a trusted analytical method in agronomy for years. Many grain quality indicators are routinely measured or researched using NIR. NIR is a highly cost effective testing process, offering an alternative to ongoing expensive, and time consuming, laboratory-based wet chemistry. ASD’s portable and online NIR technology systems can be implemented at numerous points throughout the grain or seed production process where and when analysis is most beneficial.
The use of Unmanned Aerial Systems (UASs – also knows as UAVs or “drones”) is growing rapidly in the field of remote sensing as a new and versatile tool for data acquisition in areas such as agricultural resource monitoring, soil characterization, and environmental monitoring. Specific examples where sensors mounted on UASs have provided useful results include water stress detection in agricultural crops, plant biomass and nitrogen content in crops and grasses, yield forecasting for crops like wheat and rice, rangeland management, leaf area index, NDVI (Normalized Difference Vegetation Index) and vineyard management.
Geologists use ASD spectrometers such as the TerraSpec® 4 and the TerraSpec Halo to help define alteration halos around hydrothermal ore bodies. By using the TerraSpec to differentiate subtle shifts in mineralogies, geologists can identify alteration halos and map zones of advanced argillic, propylitic and potassic alteration such as at the Los Andes, Nicaragua project described below. This helps the geologist better understand the resource and focus drilling programs to optimize exploration time and costs.
