On Sea Ice Characterisation by Multi-frequency Sar
By means of polarimetric target decomposition, quad-pol SAR data of sea ice is analysed at two frequency bands. In particular, the non negative eigenvalue decomposition (NNED) is applied on Land C-band NASA/JPL AIRSAR data acquired over the Beaufort sea in 2004. The decomposition separates the scattered radar signal into three types, dominated by double, volume and single bounce scattering resp...
متن کاملFood frequency questionnaires: not irrelevant yet.
To the Editors: Kristal et al. (1) contend that the food frequency questionnaire (FFQ) be abandoned in epidemiologic studies of cancer for three reasons: (a) a growing lack of consistency within and across studies of diet and cancer risk; (b) poor correlations between the FFQ’s measure of protein and total energy with urinary nitrogen excretion and doubly labeled water, respectively; and (c) on...

متن کاملInevitably reborn: The reawakening of extinct innovations
In our innovation-driven world we tend to lay concepts that have lost their attractiveness to rest and rush to embrace the next giant leap. However, in most fields of creation, patterns of reawakening of old, extinct innovations can be found. It often looks as if new technological and social concepts have a life of their own, survival instincts and adaptive properties: They simply refuse to die...
متن کاملMethane excess in Arctic surface water- triggered by sea ice formation and melting
Arctic amplification of global warming has led to increased summer sea ice retreat, which influences gas exchange between the Arctic Ocean and the atmosphere where sea ice previously acted as a physical barrier. Indeed, recently observed enhanced atmospheric methane concentrations in Arctic regions with fractional sea-ice cover point to unexpected feedbacks in cycling of methane. We report on m...
