Laboratory spectral reflectance measurements at VNIR-SWIR wavelengths of 17 rock samples from Mount Murphy, West Antarctica
This dataset consists of spectral reflectance measurements in the visible to shortwave infrared wavelength range (0.35 - 2.5 micrometer) of 17 rock samples from Mount Murphy, a volcanic edifice in the Amundsen Sea Embayment of West Antarctica. These spectral measurements provide ground validation for satellite-based geologic mapping of the Mt Murphy edifice and surrounding nunataks. Samples measured for spectral reflectance were collected during the 1990-1991, 1992-1993 and 2015-2016 Antarctic Field Seasons.
Funding source: Natural Environment Research Council (NERC) Grants NE/S006710/1, NE/S006753/1 and NE/K012088/1 and studentship to JRA. The dataset is a component of the "Geological History Constraints" project of the NERC-NSF funded International Thwaites Glacier Collaboration (ITGC).

- Statement
- Reflectance spectra were acquired over the 0.35 - 2.5 um spectral range. The spectral interval and average resolution of the instrument were, respectively, 1.5 nm and 3.0 nm between 350 nm - 1000 nm; 3.8 nm and 10.0 nm between 1000 nm - 1890 nm; 2.5 nm and 8.0 nm between 1890 nm - 2500 nm. All reflectance values are interpolated to a 1 nm interval using cubic-spline interpolation. Radiance measurements of the illuminated sample were compared to radiance measurements of an illuminated reference panel, and ratioed to arrive at a reflectance value. The Spectralon(R) reference panel was post calibrated at FSF to NIST traceable standards. Calibration data is provided as a separate .csv file.
