UV characteristics of sea ice
The instrument of choice (rather, availability,) for this study was a 110+ kg (240+ pounds) spectrophotometer, which in addition to having digital control, high spectral resolution, and clean optics, made a damn fine chair while executing the measurements.
a radiometer (minus the gimp'ed flare) measured the total incoming light over the dominant portion of the solar spectrum.
the best (or classiest, at least) instrument setups are sometimes designed in the field, here note that once again, Vise-Grips are the world's perfect tool. They're holding a fiber optic cable at a precise depth in the hole augered for that purpose.
cores were pulled out of the ice (maximum thickness: 2.2 meters) near the measured area to determine the general structure of the particular sea ice measured.
