Experiment name: AnSlope 2003-04 Principal Investigator: A.L.Gordon/A.Orsi/R.D.Pillsbury PI's affiliation: LDEO/TAMU/OSU Mooring Name: West C-1 Mooring position: 71.939 deg S, 172.727 deg E Instrument depth: 436 meters Seafloor depth: 1630 meters Times: starts 04 Mar 2003, ends 27 Feb 2004 Time increment: 30 minutes Instrument type: Aanderaa RCM8s parameter min mean max sd days dir (deg true) 0.00 202.37 359.38 96.84 360.0 temp (deg C) -0.85 1.01 1.30 0.19 360.0 pressure (db) 433.30 561.08 723.50 82.98 360.0 This instrument lost its Savonius rotor on the ice during anchor descent. Pressure is often offscale during intervals of high speed. It takes the value 723.5 decibars in these episodes. In general, the pressure record is not very trustworthy. Base pressure is 434.8 decibars initially but increases to 508 decibars by the end of the record. The increase probably is due to overstressing of the sensor. In contrast, the instrument below this one shows the usual slow decrease in pressure, possibly caused by line stretch. The current meter's clock was running 6 minutes 13 seconds slow at recovery.
