Position ND2 ============ file dpn9697.a4d: File is in 11 column ACCLAIM format. Temperatures a demeaned, pressure detrended. The original data had an extra 4 channels from digiquartz sensors, but these were removed as the data was corrupted, possibly by water leaking into the modules. Drake Passage North (Pol 8). Deployed December 1996 Recovered 1997 Depth = 1050 m /1077 m Position = 54 56.64S 58 23.02W First sea bed scan is original record 996 = 1 Last sea bed scan is original record 37499 = 36504 Time base 83 secs late delt= 15.00003684 Temperature from QT49187 Pressure from QT49187 The other two sensors DQ46251 and DQ43513 produced corrupt raw data. Drift and mean removed from pressure using a linear drift. 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.
