Position SD2 ============ file dps9697.a4d: Pressure data from digiquartz sensors has been de-meaned and detrended. (a) Temperature from DQ44935 Pressure from DQ44935 (b) Temperature from DQ46267 Pressure from DQ46267 (c) Temperature from DQ52026 Pressure from DQ52026 Deployed November 1996 Recovered December 1997 Depth = 1170m Position 60 50.96S 54 43.36W First sea bed scan is original record 69 =1 Last sea bed scan is original record 38928 = 38860 Time base 63 secs late delt= 15.00002695 Drift and mean removed from pressure channels using a linear drift using filter_drift.m Stations in the Scotia Sea and Drake Passage ============================================ POL deployments in this area were first made in a section between the Falkland Islands and Signy in the South Orkney islands. These stations have names like 'FS1'. Recording then moved west to two deeper (4000 m) stations on the western side of the Drake Passage ('ND1' and 'SD1'), and, most recently, have been on a section between the Falklands and Elephant Island along the official 'Drake Passage' hydrographic section for the World Ocean Circulation Experiment ('ND2' and 'SD2' with the stations including MYRTLE in between). The nomenclature 'ND1' etc. follows that of M.Meredith, 1995. On the temporal variability of the transport through the Drake Passage. University of East Anglia Ph.D thesis. In other publications, for example: Woodworth, P.L., Vassie, J.M., Hughes, C.W. and Meredith, M.P. 1996. A test of the ability of TOPEX/POSEIDON to monitor flows through the Drake Passage. Journal of Geophysical Research, 101(C5), 11935-11947. ND1 is referred to as DN92, SD1 as DS92, ND2 as DN93 and SD2 as DS93. Most instruments were Paroscientific Digiquartz (DQ) pressure transducers with temperature also recorded. BPR's had typically 3 sensors. Instrumental drift has attempted to be removed from all records.
