Experiment name: Fram Strait Principal Investigator: E.Fahrbach/G.Rohardt/U.Schauer Affiliation: Alfred Wegener Inst. Mooring name: F3-8 Mooring position: 78.839 deg N, 7.992 deg E Instrument depth: 1006 meters Seafloor depth: 1011 meters Times: 1400 18 Aug 2005 to 0500 21 Aug 2006 Time increment: 60 minutes Instrument type: SBE-16 parameter min mean max stddev days temp (deg C) -0.91 -0.77 0.23 0.13 367.67 pressure (db) 1015.60 1021.11 1026.20 2.61 367.67 salinity (psu) 34.88 34.89 34.91 0.00 367.67 At line 1685 (1800 27 Oct 2005) the pressure series shows a change of register - an increase - of about 6 meters, as if the mooring had slid deeper. The same change occurs in the pressure record from the instrument below this one, at the same time. Coincidentally (?) this is exactly when the data from the instrument above this one ends. Possibly the top of the mooring was lost and the two deepest instruments sank about 6 meters because of a loss of buoyancy.
