Station Amsterdam (files amsterdam.*)
=================

This station was occupied by BPR's from POL during 1984-88 and from the
University of Grenoble, France during 1991-94.

POL instrumentation 1984-85 was strain gauge pressure sensor with temperature
also recorded. For 1986-1988, a Paroscientific Digiquartz pressure transducer
was used with temperature also recorded. As stated above, the datum of the
pressure measurements is not maintained from one deployment to the next.                                          
                     
See Vassie et al., Journal of Geophysical Research, 99(C1), 937-949, 1994.

For each POL record a long term instrumental drift has been removed. Station
positions (lat, lon) for the southern Indian Ocean should be regarded as
being uncertain to 1 km (or 1 minute) in these pre-GPS days - if this is an
important factor then notes of the scientists in charge can be consulted as
to SATNAV etc. information.

The pressure time series is essentially flat over most of its length but
with a drop of approximately 20 mbar between days 210 and 240 (August 1984).
From comparisons with a second pressure sensor on the rig, which
malfunctioned at day 271, we believe the rapid fall is an instrumental
effect of the strain gauge. See Vassie et al., Journal of Geophysical
Research, 99(C1), 937-949, 1994.

    box  so that the rig was parallel to the ebb and flood tide.  Inspection of 
    the site at 1430 15 May revealed that the  position  of  the  recorder  had 
    moved  about  15m  to the east due to dragging when the buoys were removed.

    1. Because the pressure is integrated over 890 seconds and then logged, the 
       time  value  assigned  to  a data cycle has been chosen as the mid-point 
       between the start and end of each integration period.                    
    2. Instrumental drift and depth have been removed, thus a drift free series

    I.O.S. Data Processing of Off-Shore Pressure Recorder Data 3                
    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    I.O.S. Data Processing of Off-Shore Pressure Recorder Data 3                
    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Clock lost 1 minute 7 seconds over 175 days 19 hours 31 minutes 7  seconds; 
    the original cycle interval and time values have been corrected.  Batteries 
    failed on sensor B+H5 (BODC series reference 47363) near  the  end  of  the 
    deployment  period.  This sensor was much noisier than sensor DQ 3845 (BODC 
    series reference 47375) for the first  10  days  of  deployment.  Drift  on 
    sensor DQ 3845 was small (approximately 12 millibars).

Station CK2 (file ck2.9394)

CK2 was station number 2 on the west side of the 'Crozet-Kerguelen line'
during a POL Indian Ocean cruise during March 93 - March 94. This file
has instrumental drift removed and is in 11 column ACCLAIM format. Three pressure
sensors were used: one Quartztronic (a) which is very
temperature sensitive; and two Digiquartz (b and c) with their own
temperature measurements which should be
acceptable.

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.

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.

and so there was no end time to check clock drift against. The instrument was
redeployed 1996-1997 and so this data was re-processed using the next year's
drift. The timings had some uncertainty in them, as the only available
deployment time was 'time on the bottom', and this was a bit uncertain. As a

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.

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.

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,

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:

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

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.



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.

was because there was uncertainty at the time of processing between the

correction should have resolved this problem. If there are any problems
please contact POL.

Station Kerguelen (files kerguelen.*)
=================
                                    
This station was occupied by BPR's from POL during 1986-88 and from the
University of Grenoble, France thereafter.

POL instrumentation consisted of Paroscientific Digiquartz pressure
transducers, with long term instrumental drift removed from each of the
records. As with data from Amsterdam and elsewhere, the datum of the
pressure measurements is not maintained from one deployment to the next.
See Vassie et al., Journal of Geophysical Research, 99(C1), 937-949, 1994.

This record stems from a short deployment of a POL 'Mark 1' BPR by the
Instituto Oceanografico of the University of Sao Paulo in 1987. PAVASAS
stands for 'Pontos Anfidromicos e Variacoes Sazonais no Atlantico Sul
(Amphidromic Points and Seasonal Variations in the South Atlantic)' which
is the IOUSP research project. The deployment was in 104m water on the
Brazilian shelf.

(a)         Pressure (mbar) from a strain gauge sensor
(b)         Pressure (mbar) from a digiquartz sensor

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.

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

Station Amsterdam (files amsterdam.*)
=================

This station was occupied by BPR's from POL during 1984-88 and from the
University of Grenoble, France during 1991-94.

POL instrumentation 1984-85 was strain gauge pressure sensor with temperature
also recorded. For 1986-1988, a Paroscientific Digiquartz pressure transducer
was used with temperature also recorded. As stated above, the datum of the
pressure measurements is not maintained from one deployment to the next.                                          
                     
See Vassie et al., Journal of Geophysical Research, 99(C1), 937-949, 1994.

For each POL record a long term instrumental drift has been removed. Station
positions (lat, lon) for the southern Indian Ocean should be regarded as
being uncertain to 1 km (or 1 minute) in these pre-GPS days - if this is an
important factor then notes of the scientists in charge can be consulted as
to SATNAV etc. information.

For the records for 1991 onwards, obtained from colleagues at the University
of Grenoble, no attempt has been made to remove possible
long-term drifts in these pressure measurements.                                  
Station Amsterdam (files amsterdam.*)
=================

This station was occupied by BPR's from POL during 1984-88 and from the
University of Grenoble, France during 1991-94.

POL instrumentation 1984-85 was strain gauge pressure sensor with temperature
also recorded. For 1986-1988, a Paroscientific Digiquartz pressure transducer
was used with temperature also recorded. As stated above, the datum of the
pressure measurements is not maintained from one deployment to the next.                                          
                     
See Vassie et al., Journal of Geophysical Research, 99(C1), 937-949, 1994.

For each POL record a long term instrumental drift has been removed. Station
positions (lat, lon) for the southern Indian Ocean should be regarded as
being uncertain to 1 km (or 1 minute) in these pre-GPS days - if this is an
important factor then notes of the scientists in charge can be consulted as
to SATNAV etc. information.

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.

Station FP1 (file fp1.8384)
===========

The file contains merged data from two separate deployments at almost the
same position - see Cartwright et al., Journal of Geophysical Research,
92(C1), 725-741, 1987 for details.

The deployment was one of several made on the Atlantic equator as part of
the FOCAL experiment.

1. Because the pressure is integrated over 890 seconds and then logged, the 
time  value  assigned  to  a data cycle has been chosen as the mid-point 
between the start and end of each integration period.                    
2. Instrumental drift and depth have been removed, thus a drift free series 
is produced with an artificial mean value.

       time  value  assigned  to  a data cycle has been chosen as the mid-point

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    I.O.S. Data Processing of Off-Shore Pressure Recorder Data 3                
    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    I.O.S. Data Processing of Off-Shore Pressure Recorder Data 3                
    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    1. Instrumental drift and depth are removed, thus the drift free series  is

       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder

    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.

       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    I.O.S. Data Processing of Off-Shore Pressure Recorder Data 3                
    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    Data processing comprises 2 stages:-                                        
    1. Instrumental drift and depth are removed, thus the drift free series  is 
       produced with an artificial mean of zero.                                
    2. Generally the pressure values have  been  obtained  by  integration  and 
       averaging  over  the  sampling  interval, followed by logging; hence the 
       time value assigned to a data cycle has been  chosen  as  the  mid-point 
       between  the  start and end time of each interval. Some pressure records 
       have been sample rate reduced from the basic time step of  the  recorder 
       to  produce  either hourly or 15 minute values, incorporating any timing 
       corrections due to clock error.

    The tide gauge was trawled up some time after 1345h 19 Nov 1974  and  taken 
    by  a  Danish  fishing vessel to Hirtshals. No timing corrections have been 
    applied. Both thermistor channels failed after 10 days although many values 
    before  this  are  suspect.  No  current meters were deployed at this site, 
    therefore a constant temperature of 7.3degC was assumed.  An  interpolation 
    program  was  used  to  produce hourly values, on the hour, of the pressure 
    record.

    Three current meters were also deployed on this mooring.  Discontinuity  of 
    approximately 30 millibars between 1645h and 1700h 18 Sept 1980; tide gauge 
    moved 30cm down and evidence from the current meters on the  rig  showed  a 
    decrease  in pressure suggesting that the sub-surface buoy moved up lifting 
    the anchor and dragging the tide gauge frame.
