From about 0400-0515, there are not data on the plots. This is because there are no data in the isfs...bz2 raw_data files for any of the dsms (including pond). However, rawdata files on each of the dsms appear to be complete.
Our current thought is this was due to a power outage at least at the base trailer. "flux" stayed up, but "eddy" appears to be down. /media/backup on flux also was unmounted, also suggesting a power drop.
Nevertheless, we shouldn't have lost data due to battery-backed-up power at the sites.
