Changes in the south polar region were announced late last year. Is there more to this story now??

HA! Check out my post in the SAR 48-49 thread, post # 6 placed on Oct 3rd. I showed the same change in the lakes comparing the T36 and T49 overlap region as is discussed in the second paper in Olvegg's post above! While I thought the change from radar dark to radar bright in the floor of these small pothole lakes or calderas might be a seasonal drying up effect I wasn't really sure. This seems to be the radar teams reasoning as well.
