Experiment name: NPEO Principal Investigator: K.Aagaard Affiliation: U of Washington Mooring name: NP 2001-02 Mooring position: 89.557 deg N, 66.647 deg E Instrument depth: 55 meters Seafloor depth: 4293 meters Times: 0830 10 Apr 2001 to 1652 19 Apr 2002 Time increment: 30 minutes Instrument type: Seabird SBE16 parameter min mean max stddev days temp (deg C) -1.84 -1.79 -1.72 0.03 374.38 pressure (db) 52.58 55.63 63.93 0.72 374.38 cond (mmho/cm) 25.12 26.48 26.67 0.09 374.38 salinity (PSU) 31.66 33.52 33.73 0.12 374.38 Pressure inceases by about 3 db during the first several hours. Some deeper instruments show the same increase. This may indicate that the mooring slid deeper, or that the pressure sensors became acclimated slowly. Conductivity shows a similar initial increase, by about one mmho/cm. This appears to be a sensor problem rather than a depth increase, since it it unlikely that conductivity would change that much over 3 meters of depth.
