END_MICROSCOPIC_EXAMINATION.

SPECTROSCOPIC_DISCUSSION:

The spectrum shown is the original data interpolated to our wavelengths and water first surface reflectance added. The reflectance (r) of the first surface reflection was computed using standard water index of refraction (n), where r = (n-1)² / (n+1)².

Original spectral history traces to: spd0109, record 250.
