FOREWORD Oceanographic measurements are rarely taken as isolated spot readings. Most oceanographic instrument systems take simultaneous measurements of a number of different parameters and the same set of measurements is taken repeatedly at specific intervals in space and/or time. The data taken during one repetition of the basic measuring sequence is usually called a data cycle and the repetition of this cycle builds up into what is collectively called a data series. The composition of a data cycle depends not only on the manner in which the data has been collected but also on the manner in which it has been subsequently processed. In most cases the length of a series is set naturally by the period between the deployment and recovery of the instrument package. However, where the data are collected over a long period at a fixed location, it is often convenient to split the data into series on the basis of date (e.g. treating data for each year as a separate series); or whenever the instrumentation or methods of measurement change; or maybe where there is a significant break in the data measurement programme. The BODC data base is built as a collection of data series and was designed to reflect the manner in which the data were originally collected and processed. It is a generalised system capable of accommodating a full range of different types of oceanographic data irrespective of the particular parameters measured. A description of the parameters included within the data cycles of a given series is stored with the data. Each series has associated with it a series header containing information common to the series as a whole. The layout of the header is independent of the type of data and includes such information as: the reference no. assigned to the series by BODC; the originator's identifiers for the series; date/time at the start and end of the series; information on the geographic latitude, longitude and depth of the instrument; depth of the sea floor if the instrument is at a fixed location; the nominal interval between data cycles etc. Also included are coded entries to identify the originating laboratory, the type of data, the type of instrument and instrument mounting, the position fixing uncertainty and the depth datum. Also stored with the data are plain language narrative records documenting the circumstances under which the data were collected, including information on the measuring and processing procedures, the instrumentation and its calibration and performance; the type of mooring; the quality of the data; any problems encountered with the data etc. The narrative records are grouped into what are called documents and each document is given a unique reference number. On the BODC database each series has associated with it a list of document reference numbers addressing the plain language documentation relevant to that series. A given document may contain information which is either specific to a single series or is generally applicable to a number of series. There are four types of document: a) Warning documents: these are to warn the user that fundamental errors/problems have been found in the data and that they should be used with extreme caution. 24 Mar 1999 Page 1 b) Caution documents: intended to alert the user that some problems have been noted with the data - these may not invalidate use of the data but the user should take them into account. c) Basic documents: simple units of plain language text which, when concatenated together, provide the series documentation. d) Headed documents: longer documents with detailed information on standard procedures or instruments - the first line of these documents contains a title. Data documentation is compiled on the basis of the information that is supplied to BODC - this varies from comprehensive data reports to short hand-written notes. In some cases insufficient information is available for the data to be fully documented. There is little that BODC can do to improve the inherent quality of the data it banks - this is dependent on the procedures and methods used by the data originator, and the care that he takes in making and processing his measurements. However, prior to loading data onto its data base, BODC carries out a set of data screening procedures aimed at detecting significant errors or problems with the data. Any suspect properties detected are documented in the form of warning or caution documents. Whilst every care has been taken to ensure that the data and information supplied are reliable, errors may go undetected on occasions. Should you detect any problems please do not hesitate to let us know. 24 Mar 1999 Page 2 REPORT LAYOUT ------------- The qualifying documentation and header information in this report is supplied in two sections: SECTION A: Series Specific Information -------------------------------------- The information for each series starts on a new page and commences with an annotated list of the header information appropriate to the series. Any warning or caution documents associated with the series are then listed out in full. The basic documents associated with the series then follow under the caption 'Additional information stored with the data': individual documents are separated by a short dashed line. It should be noted that basic documents that exceed twenty lines of text and that are also associated with more than one of the selected series, are not listed out separately for each series but are included in the General Documentation Section - the reference no. of each of these documents is included with each series as appropriate. The Series Specific Information concludes with a list of titles and reference numbers of any headed documents that are applicable to the series. If the series is associated with a particular Project, Fixed Station (e.g. oil platform or coastal station) or Data Activity (e.g. a cruise or an instrument mooring) there may follow a reference to a document describing that Project, Fixed Station or Data Activity. When large quantities of similar data are supplied (e.g. CTD data) this section may be suppressed. SECTION B: General Documentation -------------------------------- This section contains: a) all basic documents that exceed twenty lines of text and that are also associated with more than one of the selected series b) all headed documents that are referenced by the selected series c) any documents that are available describing Projects, Fixed Stations or Data Activities with which any of the selected series are associated d) descriptions of the various parameters associated with those series which have been fully screened by BODC e) descriptions of the flags which may be associated with the data cycles Headed documents start on a new page; all documents are annotated with the BODC document reference number - also included is a list of the BODC Series Reference numbers of the series to which the document or parameter set applies. 24 Mar 1999 Page 3 SERIES INDEX This report contains the qualifying documentation and header information associated with the following data series

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. 24 Mar 1999 SERIES SPECIFIC INFORMATION Page 115 INFORMATION FOR BODC SERIES REF.

Wormley. It incorporates a seabed mounted pressure transducer interfaced to a 12 channel Normalair-Garret data logger housed in a 56cm diameter aluminium pressure sphere. The frequency modulated (FM) transducer consists of a diaphragm which when flexed by changing hydrostatic pressure varies the gap of a parallel plate timing capacitor in an LC oscillator circuit. The pressure casing enclosing the transducer circuitry is evacuated so that absolute rather than relative pressure is measured. The frequency output is divided down to about 100Hz and is counted over a period of 890 seconds to average out the unwanted fluctuations due to waves: this sampling period gives 50dB (99.999 p. cent) attenuation of energy from 10 second period waves, but only 0.006dB (0.14 p. cent) attenuation of semi diurnal tidal energy. The integration period of 890 seconds and the subsequent 10 second scanning and recording sequence are controlled by 900 second pulses from a crystal clock. The reading from each channel is recorded serially in either 3 or 4 decade BCD on 0.25 inch magnetic tape and a parity bit is added during each scan by the digital serializer. A synchronizing signal is recorded on a second track of the tape to assist in translating the magnetic tape during the data processing. The sphere containing the data logger and interfacing electronics is mounted in a tripod frame made of tubular steel with the pressure transducer mounted on the base of the framework and beneath the sphere. The tripod is supported on a disposable heavy ballast frame consisting of welded girders and the two frames are connected by 3 corrodible magnesium alloy links and a pyrotechnic release mechanism. The recorders are deployed as pop up moorings and released by acoustic release. 24 Mar 1999 GENERAL DOCUMENTATION Page 253 BODC HEADED DOCUMENT NO. 27731 Applies to BODC Series Ref.

Calibration and Data Processing of Off-Shore Tide Gauge Data Calibration of pressure/frequency sensors and thermistors are carried out using the facilities and staff at I.O.S. Bidston with the exception of pre 1975 pressure/frequency sensors, which were calibrated in the pressure chamber at I.O.S. Wormley. The data are copied from the logger magnetic tape to 9 track magnetic tape and disk. The data are either listed or plotted as an initial check. A program is then used to check the data from the temperature sensor channels, calculate and plot the temperature values and store them (if temperature sensor channels are available). A second program performs a similar function for the pressure sensor channel, using the pressure frequency coefficient to convert each pressure frequency to the frequency at the reference temperature and calculating the pressures using the pressure frequency calibration. The data values, generally at 15 minute intervals, but occasionally at 10 minute intervals, of pressure are then plotted and stored. If waterhead is required, it may be computed by subtracting atmospheric pressure and applying the hydrostatic relation:- H = P / ( d * g ) H = waterhead (cm) P = pressure (0.01 mb) d = density (kg/m3) g = gravitational acceleration (m/s2) 24 Mar 1999 GENERAL DOCUMENTATION Page 254 BODC HEADED DOCUMENT NO. 27762 Applies to BODC Series Ref.

Bidston. The data logger can sample a maximum of 20 input channels at periodic intervals and record their values by means of an incremental tape recorder in a computer compatible format. Any input channel is capable of sampling either D.C. or frequency modulated A.C. inputs - the FM inputs can be sampled for periods of 15/64, 15/16, 3.75, 15 or 60 seconds or continuously (i.e. the integrating time is virtually equal to the sampling period of the data from the channels). The number of channels scanned can be truncated to less than 20 and the sampling interval can be 1.875, 3.75, 7.5, 15, 30 or 60 minutes. Sensor packs used with the logger incorporate both a pressure and a temperature sensor and are completely self contained units with their own sensor electronics and power supplies. Different types of pressure sensor based on either strain gauge, vibrating wire or quartz crystal systems have been used on the tide gauge. A brief description of each is given below. 1) The strain gauge sensor has been developed using a Bell and Howell type 4-306 transducer and operates as a phase shift oscillator whose frequency is controlled by the ratio of output to input voltage of the transducer Wheatstone bridge network. 2) The vibrating wire sensor consists of a tungsten wire stretched between a rigid frame and a diaphragm and mounted in a magnetic field. Any movement of the diaphragm due to a change of pressure will increase or decrease the tension of the wire and hence change its natural frequency of oscillation. The wire is connected in the feedback loop of an amplifier and thus makes a variable frequency oscillator where frequency is a function of pressure. To achieve temperature compensation for the coefficient of expansion of the wire, the coefficient of expansion of the supporting frame is designed to balance the expansion of the wire. These sensors are manufactured by Vibroton and Ocean Applied Research. 3) Two types of quartz crystal pressure sensor have been used. The Digiquartz pressure sensor consists of a convoluted bellow linked to a 40kHz quartz crystal resonator coupled by piezoelectric action to an electronic resonator. The Hewlett Packard Oceanographic sensor consists of a 5MHz quartz resonator coupled by piezoelectric action to an electronic oscillator and mounted in an oil filled case adjacent to a pressure case containing the electronic circuitry. A second closely matched quartz crystal resonator is mounted in the pressure case and is therefore not exposed to hydrostatic pressure and is used for temperature compensation by heterodyning the frequency outputs of the two crystals. The data logger and batteries are housed in a 56cm diameter aluminium sphere with sufficient space for the sensor batteries, acoustic release electronics and ancillary sensor electronics. The sphere and a number of sensor packs are mounted in an aluminium sub-frame which in turn is 24 Mar 1999 GENERAL DOCUMENTATION Page 255 BODC HEADED DOCUMENT NO. 27762 (continued) protected by a heavy steel outer frame. The Mk II tide gauge is usually deployed using a U-shaped mooring (i.e. buoy or pellet float to wire rope to tide gauge to ground line to anchor to wire rope to buoy), but W-shaped moorings are used in conjunction with either current meters or thermistor chains. A W-shaped mooring comprises pellet float to pellet line to sub- surface buoy to current meter or thermistor line to anchor weight to ground line to tide gauge to ground line to anchor weight to wire rope to surface buoy. 24 Mar 1999 GENERAL DOCUMENTATION Page 256 BODC HEADED DOCUMENT NO. 27793 Applies to BODC Series Ref.

Current meter speed and absolute pressure count are integrated over a pre-selected period (usually 10 or 15 minutes) and sampled by the logger at the same pre-selected time interval, together with spot readings of vane direction, temperature, elapsed time and rig orientation. The pressure sensor consists of a convoluted bellows linked to a 40kHz quartz crystal resonator coupled by piezoelectric action to an electronic resonator. A quartz crystal clock is used for controlling the sampling interval. The data are recorded on magnetic tape as 10 bit binary words in serial form with the frequency count from the pressure sensor stored as most and last significant counts. The pressure sensor pack, containing the Digiquartz type 2-300a quartz crystal pressure transducer but no temperature transducer, is mounted approximately 1m above the rig base, with the current meter 0.7m above the base. The rig is 1.5m in height and the base is formed by a tripod with legs of length approximately 0.7m. The current meter/pressure recorder is usually deployed using a U-shaped mooring (i.e. buoy or pellet float to wire rope to tide gauge to ground line to anchor to wire rope to buoy), but W-shaped moorings are used in conjunction with either current meters or thermistor chains.

It was then returned to Aanderaa Instruments Limited who carried out modifications changing it to the specification of an Aanderaa WLR-5. Hence from 1980 onwards the instrument is known as Aanderaa WLR-5 (serial number 500). The Aanderaa recorder uses a Digiquartz type 2-300a quartz crystal pressure transducer. The pressure sensor consists of a convoluted bellows linked to a 40kHz quartz crystal resonator coupled by piezoelectric action to an electronic resonator. The sensor pack is mounted in a low profile steel tripod frame 0.76m by 1.183m in size with the sensor level approximately 0.48m above the frame base. Data are recorded on to 0.25 inch magnetic tape on an Aanderaa data logger in the same case. A quartz crystal clock is used for controlling the sampling interval. The data are recorded as 10 bit binary words in serial form with the frequency count from the sensor stored as the most and least significant counts. There is no temperature sensor. The tide gauge is usually deployed using a U-shaped mooring (i.e. buoy or pellet float to wire rope to tide gauge to ground line to anchor to wire rope to buoy), but W-shaped moorings are used in conjunction with either current meters or thermistor chains.

The pressure and temperature recorder consists of an Aanderaa current meter type logger modified to accept input from a pressure sensor containing a Bell and Howell strain gauge or a Digiquartz pressure transducer and a platinum resistance thermometer. The pressure and temperature transducers are mounted in the same heat sink for compatible data. The pressure sensors are mounted in a protective frame of dimensions 1.75m by 1.14m by 0.66m, attached to a ballast plate or frame. Teleost recorders are deployed as pop-up moorings and released from their ballast frames by firing a pyrotechnic release by acoustic command. 24 Mar 1999 GENERAL DOCUMENTATION Page 260 BODC HEADED DOCUMENT NO. 32414 Applies to BODC Series Ref.

Mk IV Pressure Recorder This instrument was developed at I.O.S. Bidston and is a deep water pressure recorder (i.e. used at depths between 300m and 5000m). Each recorder consists of one or two Bell and Howell strain gauges and/or a Digiquartz pressure sensor and a temperature sensor. The sensors are interfaced into a Seadata cassette recording system. Sampling is usually every 3.75 minutes with the integration period equal to the sampling interval, but may be set to other sampling intervals. For example with a 3 second sampling interval and integration period the instrument may be used as a wave recorder. The recorder is housed in a tubular aluminium frame 1.3m in diameter by 1.4m in height attached to a disposable steel ballast weight. The data logger together with the associated battery supply is lowered into a central 15cm (internal diameter) aluminium tube. Sensors are mounted externally with Marsh Marine connectors. The assembly free falls to the sea floor. An acoustic release system is used to separate the ballast weight and buoyancy is provided by Corning glass spheres attached to the aluminium frame. 24 Mar 1999 GENERAL DOCUMENTATION Page 261 BODC HEADED DOCUMENT NO. 32428 Applies to BODC Series Ref.

Off-Shore Pressure Recorder Mark III The main part of the capsule is a forged aluminium sphere of 0.66m internal diameter, which contains the data logging system, acoustic command and release units and all battery supplies. Each half of the sphere is bolted to a central equatorial ring, a seal being provided by O rings. There are twelve outlets through this ring for Marsh Marine type electrical connectors. The sphere is housed in a free flooding tubular aluminium alloy frame. Also mounted on this frame are 2 pressure transducers, a sea temperature unit, 2 subsidary platinum resistance thermometers for measuring sea temperature and 2 wound nickel scrolls that act as acoustic pinger beacons. The frame and sphere, complete with attachments, have a positive buoyancy, and in order to anchor them, they are mounted on a steel tripod. The tripod is attached to the main frame by a central pyro-release unit. The system incorporates a commercial data logger modified to operate in the deep sea capsule. The logger will accept input from a total of twelve separate sources or channels. The temperature and pressure sensors have variable frequency outputs. The frequencies are counted over a 890 second period and the total count for each channel is then recorded during a scan of all channels which lasts for 10 seconds. Thus the averaged integrated pressure and temperature values are logged every 15 minutes. Temperature is measured to correct for the temperature coefficient of the pressure transducers. 24 Mar 1999 GENERAL DOCUMENTATION Page 263 BODC DATA ACTIVITY DOCUMENT NO. 31031 Applies to BODC Series Ref.

It consists of two intensive measurement programmes. FLEX - the Fladen Ground Experiment - to study the development of the thermocline and the dynamics of the plankton bloom in spring in relation to the physical, chemical and biological environment. Measurements are concentrated in a square of side 100km for 100 days from March to June. INOUT is concerned with the general circulation of the North Sea and the storm surge problem. Currents flowing into and out of the open boundaries as well as at discrete points within the sea, are measured concentrating on a period of 40 days in the stormy season from March to April. Some 200 current meters (most also recorded temperature) of which 30 were lost, and 5 offshore tide gauges were deployed over 83 stations and more than 10 ships collected hydrographic data. The Netherlands organised a collection of meteorological data. The northern boundary of INOUT is from Wick to 59deg 20min N, 0deg E then along this latitude to the Norwegian coast. The southern boundary crosses the English Channel from Portland to Cherbourg along the meridian 2deg W (approx). One of the most important reasons for the cooperative exercise, pooling data, was the need to provide large data sets for the evaluation and running of physical and ecosystem numerical models. Data underwent intradisciplinary processing and interdisciplinary evaluation. Intercomparison of Instruments: There was no field comparison station for moored instrumentation. Laboratory techniques in use for calibrating current meter compasses were compared and shortcomings eliminated prior to the exercise. The two main types (Plessey and Aanderaa) of current meter used in the exercise were compared in a simplistic way on four of the rigs and showed that at certain times the two types could give differing responses to the same velocity field simply because of differences in instrument and rig design. This point should be borne in mind whenever comparing data across instruments. Previous JONSDAP Exercises: The first JONSDAP: this achieved the systematic collection of data from all moored stations and coastal observation sites in the North Sea in the period 1971 to 1973. The second: JONSDAP 73 was a programme of tide and current measurement in the Southern Bight of the North Sea from September to October 1973. 24 Mar 1999 GENERAL DOCUMENTATION Page 265 BODC PROJECT DOCUMENT NO. 26423 Applies to BODC Series Ref.

Bidston in the North Channel of the Irish Sea, during August and September 1979, in order to study the tidal and non-tidal dynamics of the region. Currents were measured at eight stations, sea bed pressures were measured at three stations and coastal tide gauges installed to measure sea surface elevations at four sites. A density survey of the area was carried out by continuously monitoring sea surface temperature and sea water conductivity, and by taking profiles of temperature and conductivity with depth. 24 Mar 1999 GENERAL DOCUMENTATION Page 266 BODC PROJECT DOCUMENT NO. 27220 Applies to BODC Series Ref. Nos.: 33957, 33969, 33970, 33982 IOS Celtic Sea Experiment 1978 An experiment was conducted by I.O.S. Bidston in the Celtic Sea and South West Approaches to the U.K. during the period March to May 1978. Currents and sea bed pressures were measured at each of eight stations in the Celtic Sea and one station in 4000m of water at the shelf edge. Aanderaa thermistor chains were deployed at four of the stations and profiles of sea water conductivity and temperature with depth were taken during the cruises and sea surface temperatures and conductivity were continuously monitored. Coastal tide gauges measured sea surface elevation at six sites. BODC PROJECT DOCUMENT NO. 28542 Applies to BODC Series Ref.

Bidston in the Celtic Sea during the period August to October 1980, in order to study sea level, vertical current structure and circulation patterns under stratified conditions. The experiment complemented one in March to May 1978 which studied the Celtic Sea under homogeneous conditions. 19 rigs containing recording current meters, thermistor chains or pressure recorders were deployed for 50 days at 8 stations. The density field was measured during both the deployment and the recovery legs by continuous monitoring of sea surface temperature and conductivity and by recording CTD profiles. 24 Mar 1999 GENERAL DOCUMENTATION Page 267 BODC PROJECT DOCUMENT NO. 28556 Applies to BODC Series Ref. Nos.: 34174, 34186, 34198, 34205, 34217, 34229 IOS North Sea Experiment 1981 An experiment was carried out by I.O.S. Bidston in the North Sea during May and June 1981. The scientific objectives were (i) to investigate the slope of the mean sea level surface between Leith and Immingham, (ii) to study the tidal energy budget in a shallow coastal region and (iii) to measure currents around a sandbank to test theories of spring neap changes in the mean currents. 24 rigs containing recording current meters, thermistor chains or pressure recorders were deployed for 40 days at 15 stations. Data from nearby coastal tide gauges were also used. The density field was measured during both the deployment and recovery legs by continuous monitoring of sea surface temperature and conductivity and by recording CTD profiles.
