| Summary: | Progress Code: completed Statement: Note - these data should be used with caution. The chief investigator for the dataset has indicated that a better quality dataset exists, but the AADC have been unable to attain it for archive. When the instruments and CR10x datalogger were first plugged in to ship power on the 17th October, it appears that the CR10x datalogger's internal battery failed. On every subsequent power cut the timestamp reset to time 0,0,0,00:00. The files have been corrected for this, with the possible loss of up to several minutes data during power cuts of unknown duration, since the files were time-stamped assuming that the power cuts were each 10s or less in length. A file download on the 25th of October indicated that more serious problems had resulted in the loss of 2-3 days of data immediately following the previous data download on the 11th of October. The re-awakening of the logger appears to have coincided with ship power testing on the 14th (during ice station 6). On the 26th of October, the CR10x datalogger was replaced with a CR1000 datalogger, and data collection was restarted. Both the port and starboard sensors were powered, but it appears the starboard sensor was not being correctly logged, and data from the starboard side sensor was recorded as a string of zeros in the "snow2" matlab structure. Note - these data should be used with caution. The chief investigator for the dataset has indicated that a better quality dataset exists, but the AADC have been unable to attain it for archive. Matlab file containing raw data snowfall data collected aboard the RV Aurora Australis using Campbell Scientific dataloggers. Two Wenglor brand YHO3NCT8 photoelectric sensors were mounted on the forward railing of the ship's "monkey deck". The beam heights of the sensors were 18cm above the upper railing, oriented parallel to the railing (perpendicular to the long-axis of the ship), approximately 6m apart. The port sensor was purchased in 2012, from a batch of these sensors manufactured in a new ...
