Czero 101 Posted January 5, 2013 #9 Share Posted January 5, 2013 (edited) Did I read that right? was that a 24 metre jump? Actually, it was just under 14 meters... in the course of 15 seconds. If you look at all the reported data you will see that there was a spike at one of the reporting intervals: 2013 01 05 09 08 00 2 2739.077 2013 01 05 09 07 45 3 2739.072 2013 01 05 09 07 30 3 2739.083 2013 01 05 09 07 15 3 2739.064 2013 01 05 09 07 00 3 2739.055 2013 01 05 09 07 00 2 2739.074 2013 01 05 09 06 45 3 2739.077 2013 01 05 09 06 30 3 2752.514 2013 01 05 09 06 15 3 2739.054 2013 01 05 09 06 00 3 2739.095 2013 01 05 09 06 00 2 2739.070 2013 01 05 09 05 45 3 2739.042 2013 01 05 09 05 30 3 2739.079 Given that the water column height data is reported every 15 seconds (at least on sensor/monitor/channel 3), and given that the data surrounding the anomalous "spike" at 09:06:30 remains virtually unchanged, it is at least feasible, but more probably very likely, that the "spike" was an erroneous report, or something other kind of error.
