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: 1238 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 speed (cm/sec) 0.92 42.52 164.85 29.74 360.0 dir (deg true) 0.06 266.93 359.71 91.29 360.0 u (cm/sec) -163.20 -30.61 44.42 31.33 360.0 v (cm/sec) -59.45 15.73 109.33 22.95 360.0 temp (deg C) -1.59 0.23 1.07 0.26 360.0 pressure (db) 1241.70 1305.48 1618.20 75.30 360.0 This instrument's clock was running 6 minutes 25 seconds slow at recovery. There is an interesting event in the pressure record a few hours after installation. The pressure, initially at 1241.7 decibars, jumps to 1256.7 decibars. The latter figure remains the base pressure for the rest of the record, which in itself is unusual since it indicates no sensor drift or line stretch. The initial jump would indicate that the mooring had moved if it were also present in the other pressure records from this mooring. The pressure record from the shallowest Aanderaa seems to confirm movement to greater depth but the other pressure records do not.

The axes of the PVD are labelled in kilometers. Boxes mark the beginning of each month.
