R/V Nathaniel B. Palmer NBP1102 - Climate variability and predictability (CLIVAR)Entry ID: NBP1102
Abstract: The NSF-supported research icebreaker Nathaniel B. Palmer operates year-round in support of the U.S. Antarctic Program, carrying out global change studies in biological, chemical, physical, and oceanographic disciplines.
This data set consists of underway data from leg NBP1102 on the R/V Nathaniel B. Palmer. This leg started at McMurdo Station and ended at McMurdo Station.

Quality 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.
