ABSTRACT

The European Union’s Marine Strategy Framework Directive (2008) states that “Provision should be made for the adoption of methodological standards for the assessment of the status of the marine environment, monitoring, environmental targets and the adoption of technical formats for the purposes of transmission and processing of data […]”. In its 2010 Communication to the European parliament and Council on the Marine Knowledge 2020 initiative within the framework of the European Union’s Integrated Maritime Policy, the European Commission highlighted that “Fragmented standards, formats and nomenclature, lack of information on precision and accuracy, the pricing policy of some providers and insufficient temporal or spatial resolution are further barriers [to the exploitation of collected data in developing new products and services]”.

The above institutional excerpts are testimony to the pressing need to begin building a strong metrological basis for marine measurements in Europe, making it an integral part of the region’s marine observing and data management sectors. The metrological approach represents an established way to assure traceability of measurements to the Système International d'Unités (SI) and achieve true inter-comparability of data at the transnational level. Such traceability is essential to ensure:

  • the relation of acquired measurements to recognized standards;
  • the conformity of measurement practices amongst laboratories to acknowledged guidelines at both the national and international levels;
  • the provision of documentation to handle sensors and data properly.

However, metrology is rarely discussed in marine observing circles and in the marine data management community despite its intimate link to sensor performance, data quality and data usability issues. This disregard arises from ignorance concerning the rigor required of modern measuring activity and the complexity of the underlying metrological system supporting it. It must be said that the situation is also a heritage of the historical evolution of marine observing activity, which developed outside the umbrellas of national metrological institutions (NMIs) and formally recognized international metrological frameworks. Unfortunately, in today’s reality, where marine measurements and data are no longer viewed solely as a scientific tool but also as a valuable multiple-use commercial commodity and a resource for social change, this state of affairs is no longer tenable and needs to be addressed.

At the present time, there are very few scientists working formally in the field of metrology applied expressly to marine measurements (perhaps even < 10 persons per country in Europe). But, over the past few years, these small groups are beginning to work together to try to lay the foundation for a pan-European marine calibration grid in coordination with the system of NMIs and industry. Most of this activity is being, or has been, attempted indirectly, and only in small ways, within the framework of European projects and programmes, most notably, ENV05, JERICO, JERICO-NEXT and JPI-Oceans. There is a strong necessity to inform the marine observing community and the European Commission of the need for specific attention and investments on this topic as it will be fundamental to fulfilling central European policy goals such as the Marine Strategy Framework Directive and Blue Growth.
