Show Abstract
Radiation measurements made during the spring 2008 cruise to the Fram Strait. Transmission of light through ice, measured by divers. 1st site 10 m from floe edge, 2.43 m total thickness; 2nd site 15 m, 3.09 m; 3rd site 20 m, 3.46 m; 4th site 30 m, 4.08 m. OVC, snowing, sun barely visible through clouds, 5-15 cm new snow. Each measurement type (incident, reflected, etc) was made with a different TriOS Ramses spectroradiometer. These are known to have calibration issues at the longest and shortest wavelengths for which data are reported; we recommend using only data from about 350 to 920 nm. No significant quality control has been done to these data.
