RAPID Cruise JC064 CTD instrument description
CTD unit and auxiliary sensors
The CTD configuration comprised a SeaBird Electronics 9plus system #09P0943, with accompanying SeaBird Electronics 11plus V2 deck unit #11P246800587. The CTD frame was fitted with two SeaBird 3 Premium temperature sensors, two SeaBird 4 conductivity sensors, a digiquartz temperature compensated pressure sensor, a SeaBird 43 dissolved oxygen sensor and a benthos PSA916T 7Hz altimeter. All instruments (other than cast 012) were attached to a SeaBird 24 position carousel #32198170243 containing 12 Ocean Test Equipment 10L water samplers (#1A, 3A, 5A, 7A, 9A, 11A, 13A, 15A, 17A, 19A, 21A and 23A) and were used in alternate positions on the CTD frame. This was to allow moored instruments to be strapped to the frame for calibration purposes. Cast 012 used 24 bottles and therefore included the remaining even numbered samplers (#2A, 4A, 6A, 8A, 10A, 12A, 14A, 16A, 18A, 20A, 22A and 24A). The table below lists more detailed information about the various sensors.

SeaBird Electronics SBE 911 and SBE 917 series CTD profilers
The SBE 911 and SBE 917 series of conductivitytemperaturedepth (CTD) units are used to collect hydrographic profiles, including temperature, conductivity and pressure as standard. Each profiler consists of an underwater unit and deck unit or SEARAM. Auxiliary sensors, such as fluorometers, dissolved oxygen sensors and transmissometers, and carousel water samplers are commonly added to the underwater unit.
Underwater unit
The CTD underwater unit (SBE 9 or SBE 9 plus) comprises a protective cage (usually with a carousel water sampler), including a main pressure housing containing power supplies, acquisition electronics, telemetry circuitry, and a suite of modular sensors. The original SBE 9 incorporated SeaBird's standard modular SBE 3 temperature sensor and SBE 4 conductivity sensor, and a Paroscientific Digiquartz pressure sensor. The conductivity cell was connected to a pumpfed plastic tubing circuit that could include auxiliary sensors. Each SBE 9 unit was custom built to individual specification. The SBE 9 was replaced in 1997 by an offtheshelf version, termed the SBE 9 plus, that incorporated the SBE 3 plus (or SBE 3P) temperature sensor, SBE 4C conductivity sensor and a Paroscientific Digiquartz pressure sensor. Sensors could be connected to a pumpfed plastic tubing circuit or standalone.
Temperature, conductivity and pressure sensors
The conductivity, temperature, and pressure sensors supplied with SeaBird CTD systems have outputs in the form of variable frequencies, which are measured using highspeed parallel counters. The resulting count totals are converted to numeric representations of the original frequencies, which bear a direct relationship to temperature, conductivity or pressure. Sampling frequencies for these sensors are typically set at 24 Hz.
The temperature sensing element is a glasscoated thermistor bead, pressureprotected inside a stainless steel tube, while the conductivity sensing element is a cylindrical, flowthrough, borosilicate glass cell with three internal platinum electrodes. Thermistor resistance or conductivity cell resistance, respectively, is the controlling element in an optimized Wien Bridge oscillator circuit, which produces a frequency output that can be converted to a temperature or conductivity reading. These sensors are available with depth ratings of 6800 m (aluminium housing) or 10500 m (titanium housing). The Paroscientific Digiquartz pressure sensor comprises a quartz crystal resonator that responds to pressureinduced stress, and temperature is measured for thermal compensation of the calculated pressure.
Additional sensors
Optional sensors for dissolved oxygen, pH, light transmission, fluorescence and others do not require the very high levels of resolution needed in the primary CTD channels, nor do these sensors generally offer variable frequency outputs. Accordingly, signals from the auxiliary sensors are acquired using a conventional voltageinput multiplexed A/D converter (optional). Some SeaBird CTDs use a strain gauge pressure sensor (SensoMetrics) in which case their pressure output data is in the same form as that from the auxiliary sensors as described above.
Deck unit or SEARAM
Each underwater unit is connected to a power supply and data logging system: the SBE 11 (or SBE 11 plus) deck unit allows realtime interfacing between the deck and the underwater unit via a conductive wire, while the submersible SBE 17 (or SBE 17 plus) SEARAM plugs directly into the underwater unit and data are downloaded on recovery of the CTD. The combination of SBE 9 and SBE 17 or SBE 11 are termed SBE 917 or SBE 911, respectively, while the combinations of SBE 9 plus and SBE 17 plus or SBE 11 plus are termed SBE 917 plus or SBE 911 plus.

BODC CTD Screening
BODC screen both the series header qualifying information and the parameter values in the data cycles themselves.
Header information is inspected for:
 Irregularities such as infeasible values
 Inconsistencies between related information. For example:
 Deepest CTD data cycle is significantly greater than the depth of the sea floor.
 Times of the cruise and the start/end of the data series.
 Length of the record, number of data cycles, cycle interval, clock error and the period over which data were collected.
 Parameters stated as measured and the parameters actually present in the data series.
 Originator's comments on instrument/sampling device performance and data quality.
Documents are written by BODC highlighting irregularities that cannot be resolved.
Data cycles are inspected using depth series plots of all parameters. These presentations undergo screening to detect infeasible values within the data cycles themselves and inconsistencies when comparing adjacent data sets displaced with respect to depth, position or time.
Values suspected of being of nonoceanographic origin may be tagged with the BODC flag denoting suspect value.
The following types of irregularity, each relying on visual detection in the time series plot, are amongst those that may be flagged as suspect:
 Spurious data at the start or end of the record where the instrument was recording in air
 Obvious spikes occurring in the data due electrical problems
 Constant, or nearconstant, data channels
If a large percentage of the data is affected by irregularities, deemed abnormal, then instead of flagging the individual suspect values, a caution may be documented.
The following types of inconsistency are detected automatically by software:
 Data points with values outside the expected range for the parameter, as defined by the BODC parameter usage vocabulary.
Inconsistencies between the characteristics of the data set and those of its neighbours are sought, and where necessary, documented. This covers inconsistencies in the following:
 Maximum and minimum values of parameters (spikes excluded).
 Anomalous readings due to the CTD package being bounced through temperature and/or salinity gradients.
This screening of the parameter values seeks to confirm the qualifying information and the source laboratory's comments on the series. In screening and collating information, every care is taken to ensure that errors of BODC's making are not introduced.
RAPID Cruise JC064 BODC CTD data processing
The data arrived at BODC in 11 MSTAR format files representing the CTD casts conducted during cruise JC064. The data contained in the files are the downcast data averaged to a 2db pressure grid. The casts were reformatted to BODC's internal NetCDF format. The following table shows the mapping of variables within the MSTAR files to appropriate BODC parameter codes:

Although there was an oxygen sensor on the CTD frame, no data were received.
The reformatted data were visualised using the inhouse EDSERPLO software. Suspect data were marked by adding an appropriate quality control flag, and missing data marked by setting both the data to an appropriate value and setting the quality control flag.
Detailed metadata and documentation were compiled and linked to the data.
RAPID Cruise JC064 Originator's CTD data processing
Sampling strategy
JC064 formed the second leg of the JC064 cruise, while JC063 was referred to as the first. The JC064 cruise began on 10 September 2011 in Santa Cruz de Tenerife. A total of 11 CTD casts were performed during the cruise along approximately 26.5°N, which includes the Eastern boundary, Mid Atlantic Ridge and Western boundary sections of the RAPIDMOC array. Two casts were performed on JC063, therefore making a total of 13 casts executed at 13 different stations. On each cast, up to 12 SBE37 MicroCATs were attached to the frame for calibration purposes. One cast (referenced as cast 012) used 24 water samplers as additional samples of Antarctic Bottom Water were desired, so no MicroCATs were attached. The CTD casts provided startpoint calibrations for instruments to be deployed and endpoint calibrations for recovered instruments. For recovered instruments that were redeployed, the postdeployment cast provided a predeployment calibration. The instruments were set to the fastest sampling rate and the CTD lowered as normal. On the upcast, the bottle stops were increased to 5 minutes to allow time for stabilisation and the provision of more accurate data. To allow the instruments to be attached to the CTD frame using bespoke attachments, up to 12 sample bottles were removed on all casts (excluding cast 012).
Data processing
Raw CTD data were transferred from the SeaBird deck unit to a LINUX machine via SeaBird software. The binary files are converted using SeaBird processing software (SBE Data Processing v7.20g). Physical units were calculated from the frequency data using the manufacturer's calibration routines and the data converted to ASCII format. The ASCII files were converted to MSTAR format and MEXEC programs run to process the data which included reducing the frequency of the data from 24Hz to 1Hz, calibrating the data, and averaging the downcast to a 2db pressure grid. A calibration was produced for the CTD primary conductivity sensor by merging the salinity sample data with the CTD data. Details of the MEXEC programs used and further details of the processing performed can be found in Cunningham et al. (2012).
Field calibrations
Independent salinity samples, obtained from the bottles on the CTD frame, were used to calibrate the CTD salinity data. Bottle samples with incorrect conductivities were identified and removed from the calibration. Data points were excluded if the residual (bottle conductivities minus CTD conductivities) was outside the limits 0.002 to 0.005 mS/cm. Also if the residual was larger than 3 standard deviations of the new station mean, the data were excluded.
A slope correction to account for sensor drift was applied such that C_{CTD}corrected_{1}=C_{CTD}*K. As no distinct groups of casts were identified, all 11 stations were treated as one block in the ctd_cal script where K=1.000027.
A quadratic fit of residual difference against pressure was then applied to remove the increase in residual with depth. The quadratic polynomial computed by ctd_cal was
ΔC = (1.6028 exp^{11}) p2 (3.6391 exp^{07}) p + 0.0007507.

Project Information
Monitoring the Meridional Overturning Circulation at 26.5N (RAPIDMOC)
Scientific Rationale
There is a northward transport of heat throughout the Atlantic, reaching a maximum of 1.3PW (25% of the global heat flux) around 24.5°N. The heat transport is a balance of the northward flux of a warm Gulf Stream, and a southward flux of cooler thermocline and cold North Atlantic Deep Water that is known as the meridional overturning circulation (MOC). As a consequence of the MOC northwest Europe enjoys a mild climate for its latitude: however abrupt rearrangement of the Atlantic Circulation has been shown in climate models and in palaeoclimate records to be responsible for a cooling of European climate of between 510°C. A principal objective of the RAPID programme is the development of a preoperational prototype system that will continuously observe the strength and structure of the MOC. An initiative has been formed to fulfill this objective and consists of three interlinked projects:
 A mooring array spanning the Atlantic at 26.5°N to measure the southward branch of the MOC (Hirschi et al., 2003 and Baehr et al., 2004).
 Additional moorings deployed in the western boundary along 26.5°N (by Prof. Bill Johns, University of Miami) to resolve transport in the Deep Western Boundary Current (Bryden et al., 2005). These moorings allow surfacetobottom density profiles along the western boundary, MidAtlantic Ridge, and eastern boundary to be observed. As a result, the transatlantic pressure gradient can be continuously measured.
 Monitoring of the northward branch of the MOC using submarine telephone cables in the Florida Straits (Baringer et al., 2001) led by Dr Molly Baringer (NOAA/AOML/PHOD).
The entire monitoring array system created by the three projects will be recovered and redeployed annually until 2008 under RAPID funding. From 2008 until 2014 the array will continue to be serviced annually under RAPIDWATCH funding.
The array will be focussed on three regions, the Eastern Boundary (EB), the Mid Atlantic Ridge (MAR) and the Western Boundary (WB). The geographical extent of these regions are as follows:
 Eastern Boundary (EB) array defined as a box with the southeast corner at 23.5°N, 25.5°W and the northwest corner at 29.0°N, 12.0°W
 Mid Atlantic Ridge (MAR) array defined as a box with the southeast corner at 23.0°N, 52.1°W and the northwest corner at 26.5°N, 40.0°W
 Western Boundary (WB) array defined as a box with the southeast corner at 26.0°N, 77.5°W and the northwest corner at 27.5°N, 69.5°W

RAPID Will the Atlantic Thermohaline Circulation Halt? (RAPIDWATCH)
RAPIDWATCH (20072014) is a continuation programme of the Natural Environment Research Council's (NERC) Rapid Climate Change (RAPID) programme. It aims to deliver a robust and scientifically credible assessment of the risk to the climate of UK and Europe arising from a rapid change in the Atlantic Meridional Overturning Circulation (MOC). The programme will also assess the need for a longterm observing system that could detect major MOC changes, narrow uncertainty in projections of future change, and possibly be the start of an 'early warning' prediction system.
The effort to design a system to continuously monitor the strength and structure of the North Atlantic MOC is being matched by comparative funding from the US National Science Foundation (NSF) for the existing collaborations started during RAPID for the observational arrays.
Scientific Objectives
 To deliver a decadelong time series (20042014) of calibrated and qualitycontrolled measurements of the Atlantic MOC from the RAPIDWATCH arrays.
 To exploit the data from the RAPIDWATCH arrays and elsewhere to determine and interpret recent changes in the Atlantic MOC, assess the risk of rapid climate change, and investigate the potential for predictions of the MOC and its impacts on climate.
This work will be carried out in collaboration with the Hadley Centre in the UK and through international partnerships.
Mooring Arrays
The RAPIDWATCH arrays are the existing 26°N MOC observing system array (RAPIDMOC) and the WAVE array that monitors the Deep Western Boundary Current. The data from these arrays will work towards meeting the first scientific objective.
The RAPIDMOC array consists of moorings focused in three geographical regions (subarrays) along 26.5° N: Eastern Boundary, MidAtlantic Ridge and Western Boundary. The Western Boundary subarray has moorings managed by both the UK and US scientists. The other subarrays are solely led by the UK scientists. The lead PI is Dr Stuart Cunningham of the National Oceanography Centre, Southampton, UK.
The WAVE array consists of one line of moorings off Halifax, Nova Scotia. The line will be serviced in partnership with the Bedford Institute of Oceanography (BIO), Halifax, Canada. The lead PI is Dr Chris Hughes of the Proudman Oceanographic Laboratory, Liverpool, UK.
All arrays will be serviced (recovered and redeployed) either on an annual or biennial basis using Research Vessels from the UK, US and Canada.
Modelling Projects
The second scientific objective will be addressed through numerical modelling studies designed to answer four questions:
 How can we exploit data from the RAPIDWATCH arrays to obtain estimates of the MOC and related variables?
 What do the observations from the RAPIDWATCH arrays and other sources tell us about the nature and causes of recent changes in the Atlantic Ocean?
 What are the implications of RAPIDWATCH array data and other recent observations for estimates of the risk due to rapid change in the MOC?
 Could we use RAPIDWATCH and other observations to help predict future changes in the MOC and climate?
