ITP60 Data Description<\/h1>\n\t

The ITP profiler was configured to operate on a pattern profiling schedule with different summer and winter schedules.\u00a0 In the summer (between deployment and October 31), the instrument conducted a 1.5 day repeating pattern of an up profile from 750 to 7 m, followed by 4 one-way (down, up, down, up) profiles between 7 and 200 m, followed by a down profile from 7 to 750 m, all spaced 6 hours apart.\u00a0 In the winter (after November 1), the instrument conducted a 3 day repeating pattern of an up profile from 750 to 7 m, followed 6 hours later by a down profile from 7 to 200 m, followed 24 hours later by an up profile from 200 to 7 m, followed 6 hours later by a down profile from 7 to 750 m, followed by a 36 hour gap before the pattern repeated.\u00a0 The complicated scheme was designed to conserve battery power to extend the lifetime of the instrument, while maximizing the acquisition of the bio-optical data during the summer months.\u00a0 In the surface package, the GPS receiver was powered hourly to obtain locations hourly, and buoy temperature and battery voltage status were recorded.<\/p>\n

The buoy generally meandered southward between 85 and 83\u00b0N along 130\u00b0E during the 6 weeks then circled east, north, and west before communications with the profiler ceased abruptly.\u00a0 At the same time, the temperature of the buoy electronics increased substantially(from -35 to -10 \u00b0C)\u00a0 indicating that ridging was likely occurring around the surface package, so that the buoy was pushed down and not covered in ice.\u00a0 Thereafter communications with the SAMI (including microcat) inductive modem were intermittent but with no data until February 2013. \u00a0The surface package continued to transmit locations until January 2013 as it drifted southward along the Lomonosov Ridge, exiting the Arctic Ocean through Fram Strait, and floated along the east coast of Greenland to the Denmark Strait.<\/p>\n
