Résumé du document : |
|
On clear moonlit nights, a band of highly polarized light stretches across the sk y at a 90 degree angle from the moon, and it was recently demonstrated that nocturnal organisms are able to navigate based on it. Urban skyglow is believed to be almost unpolarized, and is therefore expected to dilute this unique partially linearly polarized signal. We found that urban skyglow has a greater than expected degree of linear polarization (p = 8.6±0.3%), and confirmed that its presence diminishes the natural lunar polarization signal. We also observed that the degree of linear polarization can be reduced as the moon rises, due to the misalignment between the polarization angles of the skyglow and scattered moonlight. Under near ideal observing conditions, we found that the lunar polarization signal was clearly visible (p = 29.2±0.8%) at a site with minimal light pollution 28km from Berlin’s center, but was reduced (p= 11.3±0.3%) within the city itself. Day-time measurements indicate that without skyglow p would likely be in excess of 50%.These results indicate that nocturnal animal navigation systems based on perceiving po-larized scattered moonlight likely fail to operate properly in highly light-polluted areas, and that future light pollution models must take polarization into account.
