Station FS3 (Falkland-Signy Transect - Position 3 in the South) =============================================================== FS3 is a deep BPR station north-west of Signy Island. file fs3.9292.acc: Use (b) or (c). This file was updated by Philip Axe on 22 May 1998. 15 minutes was added to the timing of each scan, as the originals were 15 minutes too early. When the data was processed, the scan numbers did not tie up with the start and end of the record, and field deployment notes weren't available at that time. The correct timing was found as the sensors were unplugged at sea, and this time is identifiable in the record. For this 15 minute correction to be correct, we must accept that the scan counter did not increment by 1 at the beginning of the record. This has happened before, and so we are confident of the corrected timings. Scotia Sea - Signy end (logger no. 6) Original file name imv4 4th deployment at FS3 - FS3492 First scan - 7/1/92 14:15:00Z Last scan - 23/11/92 20:16:26:Z (scan no. 30840) - Temperature Sensor ? - Temperature sensor 3T1 (degrees C) (a) - Pressure sensor Digiquartz DQ18567 (+240000 Mbars) (b) - Pressure sensor Digiquartz DQ36573 (+240000 Mbars) (c) - Pressure sensor Digiquartz DQ38175 (+240000 Mbars) 15 minutes has been added to each scan time (22 May 1998, paxe). This was because there was uncertainty at the time of processing between the scan numbers and the start and end of the record. This 15 minute correction should have resolved this problem. If there are any problems please contact POL. 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.
