Objectives

WP12 – RESEARCH AND DEVELOPMENT ON CRITICAL OBSERVATORY FUNCTIONS

The overall objective of this work package is to enhance the capability of the FixO3 infrastructures to make very high quality observations (Tasks 1-3) and to develop of new low energy consuming platform design in order to promote more sensors per platform and extension capacities (Task 4). The tasks 1 to 3 are enhancing CO2 measurement, pH measurement and passive acoustic practices. Task 4 development will be able to be implemented on FixO3 platforms not cabled to shore and transmitting data in near real time: stand alone observatory on the seafloor, above seafloor, along mooring line and on board buoy.

Description of work and role of partners

Description of work

Task 12.1 Enhancement of CO2 measurement

UGOT (Lead); OGS, HCMR, UNEXE, NKE, CNR, CNRS

Highly relevant to ICOS, this task will perform an inter-calibration, based on specifications from WP2 and WP3. It will be done in the spirit of the JERICO Forum For Coastal Technology type initiative (not including CO2), the US ACT experiment, and the 2003 and 2009 pool-side inter-comparison exercise on CO2 in Japan. Complementing and enhancing these previous efforts, we will concentrate on surface to deep water, for open ocean sensors that are immersed and not only buoy/shipsupported. Specialists will perform this inter-calibration/evaluation.

Task 12.2 – Enhancement of pH sensors

ULPGC (Lead); OGS, ULPGC, NKE, UGOT

Photometric principles were successfully developed during EuroSITES to produce a very promising instrument. Sensors based on other physical and optical properties such as optode type sensor are now also available. This task will focus on the improvement of the existing sensors, in particular in terms of detection range and power consumption. Inter-comparisons will determine which sensors are most suitable for use at FixO3 sites. This task will be completed in conjunction with pCO2 measurements, since the combination of pH and pCO2 measurements is relevant to both upper ocean environmental change and to issues of CO2 leakage from the seafloor after subsea floor injection (EU project ECO2).

Task 12.3 – Enhancement of measurement of marine sound

UPC (Lead); HCMR, Plocan, Ifremer, CNRS, USTAN

Passive acoustics are an emerging topic of high relevance to gain insights into ecosystem function (marine organisms) and to assess anthropogenic noise pollution, which can have devastating effects on the marine fauna (i.e.The Marine Strategy Framework Directive -Descriptor 11). The technology is mature and is already implemented at several observatories eliciting high interest in the data. This task will focus on data processing and management in order to implement pre-processing software at sensor level thus reducing power consumption and the demands of data transmission and storage. Some event detection criteria will be implemented for validation: acoustic event detection, classification and localization, e.g. marine mammals, rainfall and specific signals of hydrothermal activity.

Task 12.4- Development of non cabled platform for high data volume sensors, with precise time reference

IFREMER (Lead); INGV, MI, NKE, HCMR, UPC, UAzores, TEXCEL

There is a demand for integrating high data volume sensors like ADCPs, seismometers and cameras on non cabled platforms, providing a common precision time reference. The time reference is the mandatory feature of event detection but also a stumbling stone of multidisciplinary long time series data comparison between cabled, non-cabled, satellite, lagrangian and terrestrial sources. This task will develop a low power, high throughput, time referenced, modular architecture enabling easy integration of demanding instruments. It will take into account the requirements from all FixO3 stand alone platforms: benthic stations, water column mooring and fixed buoy. The electronic interoperability will build upon the work of the WP2 sensor interoperability task and report to it. The software development will be made to cover a wide range of the most important sensors for FixO3 (in relation with WP11) and at least one high data volume instrument. The ease of integration provided by the new electronics will allow to optimise the configurations on the sites of FixO3 through spatial extension around their permanent observatory. The mechanical design has to be upgraded accordingly. For the three types of real time communicating platforms (stand alone observatory on the seafloor, above seafloor and mooring line), the capacity to prepare, store, transport and deploy a FixO3 class equipment within short notice will be studied.
