Task 4.1 Calibration(M1 – M42), (HZG, OGS, SMHI, SYKE,

NERC(POL), HCMR, CNR, IH) Objectives:• standardize and harmonize various facilities

across European networks, • share existing calibration facilities within the

network, thus significantly reducing costs • exchange and transfer know-how within the

network through a series of workshops, seminars and staff exchange.



SubTask 4.1.1: Physical sensors T, S, DO, Currents, Sea-bed Pressure

(OGS, NERC(POL), CNR HCMR)Actions:• Harmonization of calibration practices through:

– documentation and assessment of existing calibration methodologies, equipment, and reference material currently in use within JERICO suggesting recommendations for standardization and

– organization of joint calibration exercises among partners to arrive at a consensus on methodologies and specifications.

• Sharing of calibration facilities including: – joint meetings for documentation of existing calibration

infrastructures within JERICO – identification/definition of potential trans-network “nodes” for

these services.JERICO KICK OFF MEETING


Actions cont…

• Dissemination of know-how and the fostering of technical collaborations/partnerships to deal with pressure, temperature, salinity and dissolved oxygen calibration issues. This activity will provide material to WP6.



SubTask 4.1.2: Optical sensors Chl-a, Turbidly, PAR

(SMHI, IH, OGS, SYKE)Actions:• Harmonization of calibration practices through documentation and

assessment of existing calibration methodologies, equipment, and reference material currently in use within JERICO

• Sharing of calibration facilities including: – joint meetings for documentation of existing calibration

infrastructures within JERICO – identification/definition of potential trans-network “nodes” for these

services.• Designation of best practices for the use of optical sensors. This

includes recommendations on time of day and frequency for sampling, calibration procedures, anti fouling measures and procedures to combine different data to produce high quality products.



SubTask 4.1.3: Chemical sensors-Nutrients

(HZG, CNR)Chemical sensors (either wet chemistry of in situ methods) need frequent calibrations and validation with insitu samples in order to have a satisfactory quality. This is due to deterioration of chemicals, interference with other substances in the water (seasonal or spatial) and other factors. Two main categories can be identified:

– wet chemistry sensors for nutrients such as NH4, NO2/NO3, PO4, SiO4

– optical sensors, currently only for NO3.

Actions:• standardisation of Standard Operation Procedures (SOPs) for

calibration, adopting common procedures on comparisons with samples (time interval, sampling procedure etc.)



Actions cont…

• practices on analytical methods applied on seawater samples for in situ validation and long term performances evaluation of chemical sensors (pH, Total Alkalinity, TCO2, dissolved oxygen, dissolved inorganic nutrients, total/dissolved organic carbon) will be documented and harmonized.

• sharing of facilities and inter-calibration exercise between the involved institutions in order to assure a common lab quality



Task 4.2 Biofouling prevention(M1 – M42), (CNR, HCMR, SYKE, NERC(POL), HZG,

NIVA, IFREMER, CNRS) Objectives:• all different methods used across the network will be

described with reference to the cost (implementation, maintenance) and adaptability (different sensors and areas),

• there will be sharing of best practices and methodologies across the network with the aim towards a common approach

• new methods used by the community external to JERICO will be evaluated to identify and suggest possible future implementation.



SubTask 4.2.1: Physical sensors T, S(HCMR, NERC(POL), IFREMER, CNRS)

Biofouling can cause deterioration of data quality for conductivity sensors especially on fixed platforms (including instrumented ferries) and on sea bed landers.

Actions:

• sensors by different manufactures, using different techniques and geometries, will be investigated to see which are the most reliable

• dissolved oxygen sensors are commercially available which are claimed to be relatively immune to bio-fouling. These claims will be tested, as long data records are obtained



SubTask 4.2.2: Optical sensors Chl-a, Turbity, PAR

(SYKE, CNR, NIVA, HCMR)Optical sensors, especially fluorimeters are very sensitive to bio-fouling.

Actions:

• sensors by different manufactures, using different techniques and geometries, will be investigated to see which are the most reliable

• dissolved oxygen sensors are commercially available which are claimed to be relatively immune to bio-fouling. These claims will be tested, as long data records are obtained



SubTask 4.2.3: Chemical sensors-Nutrients

(CNR, HZG, IFREMER)Actions:

• identification of the chemical sensors used across the JERICO network and collection of information about the biofouling prevention methods used (implementation, maintenance and total cost).

• screening and summary of scientific literature and reports on biofouling prevention methods applied to chemical sensors, including the ones that at present are not used in the JERICO network, but that are recognized a necessary implementation for future applications (as specified by WP1.2 Implementation plan and label definition)

• comparison of the methodologies identified above with reference to effectiveness and cost.



Task 4.3 End to end QA(M1 – M42), (HCMR, CSIC, NERC (NOCS, POL),

CEFAS, SYKE, OGS, HZG, NIVA, IH, AZTI, MUMM, PUERTOS)

Objectives:• to describe best practices in all phases of the system

(pre-deployment test, maintenance, calibration etc)

• to adopt common methodologies and protocols

• move towards the harmonisation of equipment which will help in reducing maintenance and calibration costs. For this inter calibration tests and in-situ validation will be organised.



SubTask 4.3.1: Fixed Platforms(PUERTOS, HCMR, IH, OGS, NERC(POL),

AZTI)Operating fixed platforms although focusing on more or less the same parameters are characterised by very diverse equipment with different needs and requirements. Considering them as members of a European network it is very important to:

Actions:

• describe best practices in all phases of the system (preparation, deployment, maintenance, calibration etc)

• adopt common methodologies and protocols

• move towards improved overall system quality



SubTask 4.3.2: Ferry Box(NERC(NOCS), HZG, SYKE, NERC(POL),

NIVA, MUMM)

FerryBoxes are characterised by the measurement of core variables (T, S, Chl a, Turbidity) which are currently measured with different sensors by different operators. This equipment diversity is true for additional measurements (eg nutrients, O2) which are not on all FerryBox operations. To enable regional comparisons (FerryBox to FerryBox), this diversity in sensors and variables requires: transparency in best practices in all phases of the setup (e.g. sensor type, deployment, housing, calibration etc). Such transparency will enable adoption of common procedures and hence lead to quality assurance.



SubTask 4.3.3: Gliders(CSIC, OGS, CEFAS)

Gliders is a new-technology platform; it is very important that right from the start there will be efforts towards adopting common methodologies and protocols as well as harmonisation of equipment at European level. This will help reducing maintenance and calibration costs.

Actions:

• describe best practices in all phases of the system with emphasis in the optimization of design strategy and quality control.

• to adequately sample mesoscale and/or submesoscale structures in the coastal areas, we propose to evaluate and develop an optimal strategy for the deployment of individual and/or coordinated schools of gliders.



Actions cont…

• Specific quality control procedures will be developed for T,S sensors (pumped/not pumped) in areas of intense gradients such as the thermocline where thermal lag is an important issue.



SubTask 4.3.4: Running costs (CEFAS, HCMR, NIVA, CSIC, OGS,

NERC(POL, NOCS), MI, HGZ, AZTI, MUMM)

The long term sustainability of the observing systems is an important issue with running costs being the most significant burden. JERICO will provide a unique opportunity.

Actions:

• to describe in an analytical form the expenses emanating by the operation of each different system. This will be a valuable tool as it will enable the operators to compare, adjust, improve and exchange practices with ultimate goal the minimisation of costs

• to examine the possibility of shared resources i.e. Research Vessels, personnel
