The surface package continued to broadcast locations for another 18 months as it drifted through Fram Strait and with the East Greenland current through the Denmark Strait.\u00a0 The last location transmitted from ITP58 in June 2015 was east of the southern tip of Greenland.<\/p>\n<p>The plots to the right are of the final, calibrated, edited data (as opposed to the raw data presented on the active instrument pages).<\/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 profile data in MATLAB format:\u00a0<a href=\"https:\/\/scienceweb.whoi.edu\/itp\/data\/itp58final.mat\">itp58final.mat<\/a><br \/>\nLevel III 1-db bin-averaged processed profile data in ASCII format:\u00a0<a href=\"https:\/\/scienceweb.whoi.edu\/itp\/data\/itp58final.tar.Z\">itp58final.tar.Z<\/a>\u00a0and\u00a0<a href=\"https:\/\/scienceweb.whoi.edu\/itp\/data\/itp58final.zip\">itp58final.zip<\/a>\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58loc1f_510577.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58loc1f_510577.jpg\" alt=\"Plot of buoy locations.\" height=\"1350\" width=\"815\" title=\"itp58loc1f_510577\" \/>\n\t\t\t\t<\/a>\n\t\tPlot of buoy locations.\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat3f_510653.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat3f_510653.jpg\" alt=\"ITP58 temperature and salinity contours.\" height=\"1570\" width=\"1070\" title=\"itp58dat3f_510653\" \/>\n\t\t\t\t<\/a>\n\t\tITP58 temperature and salinity contours.\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat2f_510499.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat2f_510499.jpg\" alt=\"Composite plot of ITP temperature and salinity profiles.\" height=\"1300\" width=\"1100\" title=\"itp58dat2f_510499\" \/>\n\t\t\t\t<\/a>\n\t\tComposite plot of ITP temperature and salinity profiles.\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat5f_510613.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat5f_510613.jpg\" alt=\"ITP58 dissolved oxygen contours.\" height=\"860\" width=\"1070\" title=\"itp58dat5f_510613\" \/>\n\t\t\t\t<\/a>\n\t\tITP58 dissolved oxygen contours.\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat4f_510633.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/11\/itp58dat4f_510633.jpg\" alt=\"Composite plot of ITP dissolved oxygen profiles.\" height=\"1300\" width=\"600\" title=\"itp58dat4f_510633\" \/>\n\t\t\t\t<\/a>\n\t\tComposite plot of ITP dissolved oxygen profiles.\n\n","protected":false},"excerpt":{"rendered":"<p>ITP58 Data Description The ITP profiler was configured to operate on a standard sampling schedule of 2 one-way profiles between 7 and 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.
