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.

Alexander Goetz Instrument Support Program Seeks Research Proposals

May 17, 2017

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.

Moisture and Protein Composition Characteristics in Barley

May 11, 2017

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.

Ground Truthing and Calibration of Imagery Obtained Using Unmanned Aerial Systems

April 28, 2017

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.

TerraSpec® Alteration Mapping

April 25, 2017

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.

Can Light Really Tell You If You Have the Right Medication?

April 21, 2017

The cost of pharmacy mistakes is high:

“Costco Wholesale will pay $11.75 million to settle Department of Justice allegations that the chain’s pharmacies improperly filled prescriptions.

Investigations were conducted by federal authorities in Washington, Michigan and California.

Costco was accused of filling prescriptions that were incomplete, lacked valid DEA numbers and were for substances beyond doctor’s scope of practice.”

Do Not Miss Out on the April Webinar! - EcoSpec Project

The quest to collect the most accurate data can lead to innovative and creative “solutions” involving the pairing of materials and technologies alongside of an ASD instrument in order to create for a data collection solution that is capable of achieving results.      

How to Create...Towards and for a Measurable Solution

April 14, 2017

Definitions of the word “create” include, “to cause to come into being,” and/or, “to evolve from one’s own thought or imagination, as a work of art or an invention.”1

ASD and Bonsai Attending the 10th EARSeL Workshop

April 06, 2017

ASD will be attending the 10th EARSeL Workshop in Zurich, Switzerland on 19-21 April along with partner Bonsai Advanced Technologies.

ASD is pleased to be sponsoring this event this year, especially as this year happens to be the 20th birthday celebration of EARSeL’s Special Interest Group on Imaging Spectroscopy!

This EARSeL special interest group encourages, “interdisciplinary discussions among specialists working with innovative Earth Observation methods and technologies.”1
