Cruise DY077 Originator's CTD Data Processing

Sampling Strategy

A total of 23 CTD casts were preformed using a stainless steel rosette frame throughout the cruise to the Porcupine Abyssal Plain (PAP) sustained observatory. CTD cast 0013 was aborted at 100m on the return to the surface due to issues with the wire out being incorrect by 40m. The CTDs were used primarily to test sensors and releases although samples were also taken specifically for the USA Thorium group (to 350m). Samples were also taken to look at typical profiles in the region, for sediment trap water, micro-plastic analysis and method development. The new OTEG phosphate analyser, (initially there was also a nitrate one but it leaked and was removed before CTD 004), were also put onto the frame and triggered to start measurements once sub-merged. As sensors took up room on the frame only 21 of the 24 Niskin bottles were used during DY077. On each occasion that samples were taken the order of sampling was: Dissolved Oxygen, Dissolved Inorganic Carbon (DIC), Inorganic Nutrients, Salinity and associated parameters from the top 200m. The associated parameters from the surface samples were chlorophyll and PIC.

Sensor Issues

On the first three casts there were some issues with the configuration file for the Transmissometer and the Chelsea Fluorimeter being on the wrong channels. This was corrected by swapping around the channels in the software that they were assigned to. The XML. CON files were then changed to reflect this, so that when the data was replayed it was correct. The dissolved oxygen values also appeared incorrect on the first two dives, due to short turn around time, it was decided to continue with the sensor on cast 003, at which point it became very clear that the instrument was faulty. Once returned to surface, after cast was complete the sensor was replaced for S/N: 43-2818. On the first deep cast ( cast 003) it became apparent that the altimeter was incorrectly set up. The cast was completed without incident ( CTD package no closer than 35m to sea bed). On surfacing the problem was investigated and it was found it had a scale factor of 1 in its set up, this was then changed to its correct value of 15. Due to the problems on the first three dives, it has been suggested that in the future PAP cruises that a shallow CTD be carried out as test cast to check all sensor readings including altimeter. Further details of the sensor issues can be found in the cruise report.

Field Calibrations

The conductivity was not calibrated as bottle salinity samples were not deemed accurate enough by the originator. CTD Oxygen Data were calibrated against bottle samples. In order to compare oxygen bottle data with sensor data, dissolved oxygen data were converted from µmol/l to µmol/kg by dividing the values with the insitu density. More information on the unit conversion can be found on page 88 of the cruise report.

Data Processing

Data were processed by BODC on behalf of the PAP scientists using the MEXEC software suite available from the NOC Marine Physics and Ocean Climate group. The MEXEC processing follows the initial Sea Bird conversions and corrections (time alignment and hysteresis correction of oxygen data and cell thermal mass correction for conductivity). Conductivity was not calibrated as bottle salinity samples were not deemed accurate enough. The oxygen sensor was faulty throughout cruise, therefore this channel should not be processed.

Instrument Description

CTD Unit and Auxiliary Sensors

A Sea-Bird 911plus CTD system was used on cruise DY077. This was mounted on a 24-way stainless steel rosette frame, equipped with 21 Niskin bottles. As sensors took up room on the frame only 21 of the 24 Niskin bottles were used during DY077. On the first three casts the dissolved oxygen sensor was faulty and there were also some issues with the configuration files for the transmissometer and the Chelsea Fluorimeter. These sensors were replaced after cast 003. Below are the CTD sensor configuration tables for the first three casts and for the CTD sensor configuration from the forth cast onwards .

Sea-Bird Electronics SBE 911 and SBE 917 series CTD profilers

The SBE 911 and SBE 917 series of conductivity-temperature-depth (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 Sea-Bird'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 pump-fed 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 off-the-shelf 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 pump-fed plastic tubing circuit or stand-alone.

Temperature, conductivity and pressure sensors

The conductivity, temperature, and pressure sensors supplied with Sea-Bird CTD systems have outputs in the form of variable frequencies, which are measured using high-speed 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 glass-coated thermistor bead, pressure-protected inside a stainless steel tube, while the conductivity sensing element is a cylindrical, flow-through, 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 pressure-induced 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 voltage-input multiplexed A/D converter (optional). Some Sea-Bird CTDs use a strain gauge pressure sensor (Senso-Metrics) 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 real-time 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.

Specifications

Specifications for the SBE 9 plus underwater unit are listed below:

Further details can be found in the manufacturer's specification sheet.

Aquatracka fluorometer

The Chelsea Instruments Aquatracka is a logarithmic response fluorometer. It uses a pulsed (5.5 Hz) xenon light source discharging between 320 and 800 nm through a blue filter with a peak transmission of 420 nm and a bandwidth at half maximum of 100 nm. A red filter with sharp cut off, 10% transmission at 664 nm and 678 nm, is used to pass chlorophyll-a fluorescence to the sample photodiode.

The instrument may be deployed either in a through-flow tank, on a CTD frame or moored with a data logging package.

Further details can be found in the manufacturer's specification sheet.

Biospherical Instruments Log Quantum Cosine Irradiance Sensor QCP-2300 & QCP-2350

The QCP-2300 is a submersible cosine-collector radiometer designed to measure irradiance over Photosynthetically Active Radiation (PAR) wavelengths. It features a constant (better than ±10%) quantum response from 400 to 700 nm with the response being sharply attenuated above 700 nm and below 400 nm.

The sensor is a blue-enhanced high stability silicon photovoltaic detector with dielectric and absorbing glass filter assembly. The output is a DC voltage typically between 0 and 5 VDC that is proportional to the log of the incident irradiance.

The QCP-2300 is specifically designed for integration with 12-bit CTD systems and dataloggers requiring a limited-range of signal input.

Specifications

Wavelength 400 to 700 nm
PAR Spectral Response better than ± 10% over 400-700 nm
Cosine Directional Response ± 5% 0 to 65°; ± 10% 0 to 85°
Noise level < 1 mV

WETLabs Single-angle Backscattering Meter ECO BB

An optical scattering sensor that measures scattering at 117°. This angle was determined as a minimum convergence point for variations in the volume scattering function induced by suspended materials and water. The measured signal is less determined by the type and size of the materials in the water and is more directly correlated to their concentration.

Several versions are available, with minor differences in their specifications:

  • ECO BB(RT)provides analog or RS-232 serial output with 4000 count range
  • ECO BB(RT)D adds the possibility of being deployed in depths up to 6000 m while keeping the capabilities of ECO BB(RT)
  • ECO BB provides the capabilities of ECO BB(RT) with periodic sampling
  • ECO BBB is similar to ECO BB but with internal batteries for autonomous operation

Project Information

Fix03 - Fixed-Point Open Ocean Observatories

Fixed point Open OCean Observatory network (FixO3) is a EUR7 million, four-year (2013-2017) research programme network includes 29 partners from academia, research institutions and small and medium enterprises (SME). In addition, 12 international experts from a wide range of disciplines comprise an Advisory Board.

Background

FixO3 is coordinated by the National Oceanography Centre, UK, and seeks to integrate European open ocean fixed point observatories and to improve access to these key installations for the broader community. These will provide multidisciplinary observations in all parts of the oceans from the air-sea interface to the deep seafloor. FixO3 will build on the significant advances achieved through the FP7 programmes EuroSITES, ESONET and CARBOOCEAN.

Open ocean observation is currently a high priority for European marine and maritime activities. FixO3 will provide important data on environmental products and services to address the Marine Strategy Framework Directive and in support of the EU integrated Maritime Policy.

The FixO3 network will provide free and open access to in situ fixed point data of the highest quality. It will provide a strong integrated framework of open ocean facilities in the Atlantic from the Arctic to the Antarctic and throughout the Mediterranean, enabling an integrated, regional and multidisciplinary approach to understand natural and anthropogenic change in the ocean.

The programme will be achieved through:

1. Co-ordination activities to integrate and harmonise the current procedures and processes. Strong links will be fostered with the wider community across academia, industry, policy and the general public through outreach, knowledge exchange and training.

2. Support actions to offer a) access to observatory infrastructures to those who do not have such access, and b) free and open data services and products.

3. Joint research activities to innovate and enhance thee current capability for multidisciplinary in situ ocean observation.

Further details are available on the FixO3 website.

At present there is a mooring and surface buoy measuring hydrography, O2, chlorophyll and carbon parameters. Real-time and delayed-mode capabilities. This site provides the longest existing homogeneous time series from deep ocean. The facility presented here is the mooring situated between 150 and 2000m.
W1-M3A Ligurian Sea A single multidisciplinary observatory mooring with real-time and delayed mode capability. The W1-M3A observing system is composed by a large spar buoy and a sub-surface mooring periodically deployed close to the main buoy depending on specific research needs.The W1-M3A large spar buoy specifically designed for air-sea interaction studies and the collection of meteorological data even in rough sea. Stability is the basic feature of this type of buoy with respect to the other more classical approach based on discus-shaped buoys. The buoy was specifically designed as a stable measuring platform since its total mass, the unity buoyancy at the sea level, and presence of a damping disk allow for negligible sensitivity of sea heave and height.

The British Oceanographic Data centre store data from PAP, NOG and SOG as of January 2018.
