MISSION: South Peninsula DATE: 20141110 SPECIAL ISSUES: Still writing to raid system and syncing to FO. Due to the amount of data expected today, I will need to keep deleting synced files from the raid at some point. This should not be an issue as the files will be on the FO. However, for this reason I am collecting data only while flying over land and stop recording when transiting over ocean or sea ice or whenever possible. This should result in having more segments than usual. There is a side lobe near the surface return for channels 1 and 4 (rightmost) and WF2. Not there for WF0 and WF1.
