| Zusammenfassung |
| Perennial and seasonal snow profiles in Antarctica and and Greenland are deposited mostly
under windy conditions. We measured snow profiles with very high vertical resolution on
several places in Antarctica and Greenland. As instruments we measured the penetration
hardness with the SnowMicroPen (1 mm vertical resolution), with a combination of
near-infrared and translucent photography (2 mm2 resolution) and micro-CT samples (20 μm
resolution). All profiles show horizontal spatial variability caused by wind deposition, and a
vertically highly variable profile, difficult to measure by traditional means. We try a first
interpretation of the features found in these profiles and features typical for certain regions. |
