Problem Reports

Chlorophyll

Post deployment, a calibration against the CTD fluorometer revealed that the Turner Cyclops fluorometer was recording at a 10 x gain (below 50 m). This was corrected by wet chemistry, using the calibration from the RRS Discovery Cruise DY050 cruise report draft. Data diverged at the end of the deployment due to a slight amount of bio-fouling. The wiper was not working when the mooring was recovered. It was estimated that the operation failed a few weeks before recovery. Please see the DY050 cruise report for further detail.

BODC flag M hs been applied to a single spike in chlorophyll concentration data (CHLTVOLU), this was the value of 0.41 mg/m³ recorded at 22:30 on 11/12/2015.

BODC flag M has also been applied to all values of CHLTVOLU below 0 mg/m³ (4 cycles out of 7174). Values for chlorophyll concentration below 0 mg/m³ are outside of BODC parameter limits, indicating there may be a problem with the data.

CHLTVOLU was recorded by the following instrument: Turner Designs Cyclops-7F fluorometer.

PAP1 Mooring Turner Cyclops Fluorometer: DY032 BODC Data Processing

The mooring was deployed on the RRS Discovery Cruise DY032 (01/07/2015) and recovered by the RRS Discovery Cruise DY050 (25/04/2016), at the Porcupine Abyssal Plain - Sustained Observatory (PAP-SO) site in the North East Atlantic ocean. The Cyclops Turner fluorometer (SN 2103960) was mounted to the Aanderaa Seaguard platform (SN 1614) on the frame at 30m with a ZebraTech wiper set to activate every 6 hours. Data diverged at the end of the deployment due to a slight amount of bio-fouling. The wiper was not working when the mooring was recovered. It was estimated that the operation failed a few weeks before recovery.

The data were supplied to BODC in .xlsx format. This was converted to a .csv format by BODC. The data were then loaded into BODC's database using established BODC data banking procedures. For more information on the deployment of these instruments please see the DY032 cruise report.

The originator variables were mapped to appropriate BODC parameter codes as follows:

The reformatted data were visualised using in-house EDSERPLO software. Any suspect data were flagged using the BODC quality control flags.

PAP1 Mooring Turner Cyclops Fluorometer: DY032 Originator Data Processing

The mooring was deployed on the RRS Discovery Cruise DY032 (01/07/2015) and recovered by the RRS Discovery Cruise DY050 (25/04/2016), at the Porcupine Abyssal Plain - Sustained Observatory (PAP-SO) site in the North East Atlantic ocean.

Prior to the mooring deployment, the Seaguard was deployed on CTD (conductivity, temperature and depth) cast 020 (25/06/2015) in order to calibrate the oxygen optode and fluorometer against the CTD sensors. The CTD cast went down to 200 m. The Turner Cyclops fluorometer was calibrated against the WETlabs sensor (SN 30250), which was mounted on the base of the CTD.

During this deployment, the Cyclops Turner fluorometer (SN 2103960) was secured to the Aanderaa Seaguard platform (SN 1614), along with an Aanderaa 4339 oxygen optode (SN 2001) and a DCS current meter (SN 685). The Seaguard was set-up and secured in its pressure housing. The unit was then integrated into the sensor frame to be positioned at 30m and armed to start operating before deployment, to ensure correct communication to the Hub. It began operating at 12.30 on 27/06/2015. The Cyclops Turner fluorometer was mounted in a ZebraTech wiper set to activate every 6 hours. It was started at 14.00 on 28/06/2015 so that the wiper would activate on the hour, minimising the chance a wipe would happen at the same time as a measurement by the fluorometer.

Post deployment, a calibration against the CTD fluorometer revealed that the Turner Cyclops fluorometer was recording at a 10 x gain (below 50 m). This was corrected by wet chemistry, using the calibration from the RRS Discovery Cruise DY050 cruise report draft.

Data diverged at the end of the deployment due to a slight amount of bio-fouling. The wiper was not working when the mooring was recovered. It was estimated that the operation failed a few weeks before recovery.

Please see the DY032 cruise report and DY050 cruise report for further detail of originators processing.

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 including 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 the current capability for multidisciplinary in situ ocean observation.

Further details are available on the FixO³ website.

Data Activity or Cruise Information

Data Activity

Moored Instrument Rig PAP1_072015

This rig was deployed as part of the Porcupine Abyssal Plain (PAP) observatory project. 'PAP1_072015' refers to the deployment of mooring number 1 in July 2015 ('072015') located at the PAP Observatory. This was the eleventh deployment of this mooring configuration at the PAP site, under this project.

Data summary

Instrumentation

The mooring design is an 'S' tether configuration allowing the mooring to better withstand the extremes of the environment it is in. The main surface buoy is an ODAS (Ocean Data Acquisition System) buoy, and below this buoy are 30 meters of chain with a conducting cable running along side. The chain is there to take the loads that the mooring will experience and the cable is a vehicle for the data. Attached to the bottom of the chain is the instrument frame, and coming out of the bottom of the frame is a cable attached to a subsurface buoy, an acoustic release and then finally a 3 tonne sinker weight. Further details on page 15 of the deployment cruise report.

Instruments on the subsurface frame are listed below:
