Position Myrtle

file myr9296.a1d: (b) contains pressures
from the Quarztronic sensor which stops working near to the end of the record.
(a) contains pressures from a Digiquartz throughout the record
(mbar) but exhibits a large drop in pressure at the start of the record.
Otherwise the two are very similar.

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.
