ASD’s 2017 series continues from last year, providing educational webinars that focus on one spectroscopy research application use of an ASD instrument each month. Webinars focus on topics such as theories behind the application, methodologies, analyzing and interpreting data, and using instrumentation.
This February, our webinar season kicks off focusing on the application of geochemical conditions and features ASD’s TerraSpec® Halo mineral identifier.
In this webinar you will learn about:
- Performing lab and field analyses that provide ground truthing for orbital remote sensing
- Specifically for VNIR/SWIR spectra collected by CRISM on-board MRO
- Analog sites: alteration of volcanic material, hot springs, deserts
- Lab samples: pure minerals with varying chemistry; mineral mixtures
- Carrying out the spectral identification tasks related to hydrated minerals and surface alteration
- Band position and shape
- Multiple bands improves accuracy
- Characterization of the Martian surface via spectroscopic investigations
- Orbit: CRISM at Mawrth Vallis, Juventae Chasma, Libya Montes
About our speaker:
Dr. Janice Bishop holds a PhD in Chemistry from Brown University and an MS in Applied Earth Science, Remote Sensing from Stanford – she is a chemist and planetary scientist who explores the planet Mars using spectroscopy. Her investigations of CRISM data of Mars are revealing clays and sulfates in the ancient rocks that provide information about the geochemical environment at the time the minerals formed. Dr. Bishop studies the spectral fingerprints of minerals and rocks in the lab in order to generate a spectral library for identification of these in the Martian data. Her research also involves collecting and studying Mars analog rocks and soils at a variety of locations including volcanic islands, cold deserts, hydrothermal regions, acidic aqueous sites, and meteorites which are the only Martian samples available on Earth to date.
Another component of Dr. Bishop’s research is collecting spectra under Mars-like conditions. Spectra of many hydrated minerals change depending on the moisture level in the air and the amount of water molecules adsorbed on the surface or bound in the mineral structure. Understanding the spectral properties of mineral mixtures in the lab is also important for identifying minerals on Mars and Dr. Bishop’s group is preparing and characterizing the spectral properties of several mixture suites.
