Experiment name: AnSlope 2003-04 Principal Investigator: A.L.Gordon/A.Orsi/R.D.Pillsbury Affiliation: LDEO/TAMU/OSU Mooring name: ADP-1 Mooring position: 71.981 deg S, 172.595 deg E Instrument depth: 872 meters Seafloor depth: 890 meters Times: 2029 06 Mar 2003 to 0100 27 Feb 2004 Time increment: 30 minutes Instrument type: SBE-37 MicroCat parameter min mean max stddev days temp (deg C) -1.88 -0.39 0.84 0.64 357.21 pressure (db) 884.50 908.47 923.70 7.34 357.21 cond (mmho/cm) 27.64 28.89 29.92 0.53 357.21 Each of the four instruments on this mooring contained a pressure sensor. All four of the pressure records show that the mooring slipped downslope somewhere between 20 and 24 meters (measured vertically) during the experiment. Some of the depth changes were gradual and others were abrupt. For example, the deepest Microcat (Accession 4679) experienced pressure increases of about 2.5 meters on 29 March 03, 2.4 meters on 24 April, 4.9 meters on 19 May, 1.9 meters on 20 May, and 1.3 meters on 5 February 04. Corresponding pressure changes can be found in the pressure records of the other instruments on the same dates. Although the deepest Microcat and the Sontek ADP were at the same depth, the ADP's pressure record reads 7 to 9 meters shallower than the Microcat's. Mooring depths were calculated using the Microcat's pressures.
