750 m depth each day.\u00a0 In the surface package, the GPS receiver was powered hourly to obtain locations, and buoy temperature and battery voltage status were recorded.\u00a0 Buoy drift speeds stayed mostly between 10 and 30 cm\/s, with a few spikes exceeding 40 cm\/s.<\/p>\n<p>After 108 days of normal operation, the profiler began having difficulty transferring files to the surface unit on December 18, 2008.\u00a0 The profiler continued to ring the surface unit on the inductive modem circuit for three more days, but was not able to successfully continue file transfers.\u00a0 On this day, the surface unit began intermittently restarting itself indicating a potential hardware problem, and no more rings were heard from the underwater package.\u00a0 However, status information, including GPS locations, continued to be obtained and telemetered for 2 more years as the system drifted out of the Makarov basin, and continued along the northeast coast of Greenland and through Fram Strait.<\/p>\n<p>See the Data Products tab to the left for descriptions of the three levels (I, II, III) of data processing and to access all data.<\/p>\n\n\n\nLevel III 1-db bin-averaged processed
