Pedersen	Combined airborne profiling over Fram Strait sea ice: Fractional sea-ice types, albedo and thickness measurements	2009.0	30	.pdf	application/pdf	9118	650	63	Fractional Sea-Ice Types, Albedo and Thickness Measurements�, submitted to Cold Region the variance in sea-ice types, albedo and thickness, and the techniques used to analyze the data. Relative high correlations were found between the measured albedo and sea-ice concentration (0.69), measure the variance in sea-ice types, albedo and thickness, and the techniques Previous studies on classifying sea-ice types from helicopter images has mostly extraction of spectral characteristics from AVHRR images, resulted in distinguishing between six sea-ice types (Lythe et al., 1999). thin ice and open water based on the measurements from the airborne sea from the classified images (the fraction of sea-ice types within the spectrometer The test and training data sets (Sec. 3.1.3) were created by manually classifying 120 000 pixels within 23 images to each of the four sea-ice classes. spectral unmixing uses the optical features for classifying the reflectance measurements, and the thresholded EM data only consider the sea-ice thickness.	./cache/work_cqtozv7subba5fgsvz5wcpqxza.pdf	./txt/work_cqtozv7subba5fgsvz5wcpqxza.txt
