Station FS1 (Falkland-Signy Transect - Position 1 at the North) =============================================================== file fs1.9292.acc: Use (a) or (b). However, note that a temperature sensor failed on this deployment, thus data for 21st July 1992 onwards are not temperature-corrected and therefore not useable (flagged). Also note the warnings about timings etc. at start of file - phases here look about 3 degrees later compared to deployments 1 and 2, and there are residual tidal signals. No instrumental drift has been removed from this file as it seemed very small. Scotia Sea Stanley end. Position FS14 12th January 1992 to 15th November 1992 53 31.4 S 57 01.9W Depth 2800mIDE GUAGE RECORDER 2T4 (a) DQ 41097 (b) DQ 41083 (c) DQ 41079 Drift very small so not removed from pressures. Hourly values in this file. Raw data was originally corrupted due to tape fault Reprocessed many times by DUS to produce the following file Temperature has a high pre-division factor hence low resolution 3 pressure channels show good agrement The temperature sensor fails from 21st July 1992 onwards. The records after this date are therefore not temperature corrected. The variability in the low frequency is noticeable higher so treat this part of the record with caution Tidal analysis shows M2 phase 3 degrees later than previous deployments There is no indication of timing errors but a tidal residual is evident of approx +- 5 mbar in all channels. 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.
