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.
