Final report of the Coastal Surveillance Through Observation of Ocean Color (COASTlOOC) oceanographic expeditions conducted in 1997 and 1998.

An improved understanding of the global carbon cycle is important to the success of efforts to mitigate climate change, such as agreed in the Paris meeting of the UN Conference of the Parties in 2016. Climate change mitigation and adaptation requires action by individual countries, municipalities, cities, and their citizens. These actions require a diverse range of information. Current efforts responding to the need for these carbon observations are, however, fragmented. There is a need to coordinate observations on carbon, GHG measurements, and ecosystem processes related to carbon cycle dynamics. The GEO Carbon and Greenhouse Gas Initiative (GEO-C) was launched to further support continuity and coherence of the ongoing efforts and facilitate their cooperation and interoperability. The GEO-C Initiative (1) supports the development of a holistic cross-domain, global carbon cycle and GHG monitoring system that provides long-term, high quality, and open access; (2) engages with users and policy makers and ensures the fitness for purpose of the observation and reporting system; and (3) aims to establish a common terminology (including scientists and decision makers) involved in addressing GHG emissions. This chapter describes the background of the GEO-GHG initiative and describes the main aims of the initiative and first steps toward implementation.

The Copernicus programme for Earth observation represents a big investment by the EU, justified by expected returns in public governance and private business. Copernicus is user and policy driven, and provides cross-domain products and services with a full free and open data policy and where possible taking up new technologies and research. This study has made a survey of the extent that Copernicus is used to support policy making in the European Commission, also assessing the perspectives for increased uptake. Also other Earth observation data and information has been looked at. An extensive use of the services is observed for policies monitoring landuse, climatic and environmental conditions, and this is expected to increase further with e.g. the new Common Agricultural Policy and the Land Use, Land-Use Change and Forestry Regulation. Information of the Climate Change Service on optimal land-use targeting specific human activities, harnessing the beneficial opportunities of climate change, provides policy makers with a new set of adaptation measures. While air quality measures can be monitored by the atmosphere service, the marine service provides input to the information system for marine knowledge. The emergency service supports disaster risk reduction measures and a resilient build-up of society. Security is of increasing importance where land and water resources are at the origin of conflict and migration. Several lines of action have been identified to improve uptake: Increasing engagement within the policy Directorates-General, fostering feedback loops between the end-users and Copernicus services, Increasing communication, information and training, setting standards and guaranteeing quality controls, enabling full integration of different datasets. The Copernicus programme brings a unique opportunity to the EU for being a global player, addressing SDGs and International Conventions because of its a long-term sustained commitment and strong international dimension. No such space programme is currently available elsewhere., JRC.D.6-Knowledge for Sustainable Development and Food Security

This is the third report form the CO2 Monitoring Task Force on the multiple input streams of in-situ observations that are requirement for the Copernicus CO2 Monitoring and Verification Support capacity to: (i) calibrated and validate the space component, (ii) assimilate data in the models and integrate information in the core of the system, and (iii) evaluate the output generated by the system for its end users. The availability of sustained in situ networks is currently a significant factor of risk that needs to be mitigated to establish a European CO 2 support capacity which is fit-for-purpose. The current status of existing networks may be the source of large uncertainties in anthropogenic CO2 emission estimates as well as limited capability in meeting the requirements for country, large city and point source scale assessments. This conclusion results from a risk analysis formulated for four scenarios: 1) maintaining the status quo, 2) assuring sustained funding for the status quo, 3) enhancing network capabilities at European scale with sustained funding and 4) with a significantly improved in situ infrastructure in Europe and beyond. This report substantiates the multifaceted needs and requirements of the European CO2 support capacity with respect to in situ observations. The analysis concerns all core elements of the envisaged integrated system with a particular attention on the impact of such observations in achieving the proposed objectives. The specific needs for the validation of products delivered by the space component that is, the Copernicus Sentinels CO2 monitoring constellation, are addressed as another prerequisite for the success of the CO2 support capacity. This European asset will represent a significant contribution to the virtual constellation proposed by the Committee on Earth Observation Satellites (CEOS) and, accordingly, complementary requirements are elaborated in that international frame. The report highlights that although high measurement standards are present within existing networks such as ICOS, in the context of the needs for targeted in situ data for the realization of the operational system, these data are not fully fit-for-purpose. A fundamental prerequisite is to have a good geographical coverage over Europe for evaluating the data assimilation and modeling system over a large variety of environmental conditions such as, for instance, urban areas, agricultural regions, forested zones and industrial complexes. The in situ observations need to be extended under a coordinated European lead with sustained infrastructure and targeted additional and maintained long-term funding. It has been clearly understood from the onset that the international dimension of the European CO2 support capacity would be critical and that these aspects should be developed in parallel to, and in synergy with the definition and implementation of a European contributing system. It was also understood that this international dimension had both strategic, policy relevant and technical dimensions and the Commission and the relevant European institutional partners have started since several years to engage both bilaterally and multilaterally with the relevant stakeholders and counterparts to develop these relations. Specifically, CEOS will undertake, over the next few years, dedicated preparatory work in a coordinated international context, to provide cumulative added value to the specific programmatic activities of their member agencies. Concerted efforts have already begun in the context of the European Commission's Chairmanship of CEOS in 2018. It is recognized in the context of the European efforts, and increasingly by our international counterparts that a broad and holistic system approach is required to address the requirements which are represented by the climate policy, of which the satellite component, whilst important, cannot effectively be developed in isolation. This system indeed includes the satellite observing capability but in addition, the required modelling component and data integration elements, prior information, ancillary data and in situ observations delivered by essential networks. Acknowledging the need for an efficient coordination at international level for instance via the Global Atmosphere Watch programme of the World Meteorological Organisation is a key towards a successful implementation of appropriate actions to ensure the sustainability of essential networks, to enhance current network capabilities with new observations and to propose adequate governance schemes. Such actions to mitigate current network limitations are deemed critical to implementing the Copernicus CO 2 Monitoring & Verification Support capacity in its full strength., JRC.D.6-Knowledge for Sustainable Development and Food Security

The report is the result of fruitful collaboration between EASAC and the JRC. It has been prepared by a working group of experts drawn from the European National Science Academies, which was supported by the JRC. It is hoped that the report will prove useful in the further development and implementation of European Union marine and maritime policy as well as the organisation of supporting science needed to inform and guide these policies. The last ten years have seen a growth in marine and maritime policymaking within the European Union with a key feature being the concept of the ecosystem approach to guide sustainable use of the seas. In view of this increasing focus on coherent marine and maritime policy and governance within the EU, as well as globally, the EASAC Council decided in December 2013 to conduct a study on the issue of marine sustainability. This decision particularly acknowledged the need to provide advice from the point of view of the European science academies on this new direction of marine policy and to highlight the particular challenges that this poses to the organisation of science. The report has the aim of contributing to the governance challenge of how to integrate the various aspects of marine policy (fisheries management, biodiversity conservation and marine environmental protection) as part of a coherent ecosystem approach. It considers how current science knowledge on marine ecosystems and the organisation of science can support an integrated approach to management of the seas. The report looks at a number of key aspects for sustainable development in changing oceans and seas, and particularly highlights the key scientific challenges in addressing these issues. The report presents both recommendations from science for policy development, and recommendations on policy for science. The health of the oceans and coastal seas is vital for the future well-being of all of Europe, indeed of entire mankind, and sustainable management of this sensitive and fast changing component of the global ecosystem is essential., JRC.A.3-Inter-institutional, International Relations and Outreach

The Arctic is experiencing unprecedented and disproportionately high rates of environmental change due to effects of climate change. These changing conditions are making it easier to exploit the natural wealth of the Arctic (mineral, fisheries, land) while putting the existence of Arctic ecosystems and the indigenous population that rely on them under threat. EU institutions have recognised these opportunities for, and threats to, the Arctic. The EU Commission and the EEAS (European External Action Service) are due to “present proposals for the further development of an integrated and coherent Arctic Policy” in the first quarter of 2016. A cornerstone of EU efforts is engagement with the Arctic Council, the high-level intergovernmental forum of States bordering the Arctic, representatives of indigenous peoples, and permanent observers (including seven EU Member States). The Arctic Council has not yet pronounced on the EU’s longstanding application for observer status, and will not do so before 2017. By virtue of its scientific excellence, JRC engagement with the Arctic Council and its subsidiary bodies is therefore currently one of the few channels for direct engagement of the EU with the Arctic Council. This report presents JRC activities in support of the Arctic Council and its bodies, and possibilities for their further development, identifying three alternative paths for future engagement in support of EU Arctic policy making., JRC.H.2-Air and Climate

The performance of 36 models (22 ocean color models and 14 biogeochemical ocean circulation models (BOGCMs)) that estimate depth-integrated marine net primary productivity (NPP) was assessed by comparing their output to in situ 14C data at the Bermuda Atlantic Time series Study (BATS) and the Hawaii Ocean Time series (HOT) over nearly two decades. Specifically, skill was assessed based on the models' ability to estimate the observed mean, variability, and trends of NPP. At both sites, more than 90% of the models underestimated mean NPP, with the average bias of the BOGCMs being nearly twice that of the ocean color models. However, the difference in overall skill between the best BOGCM and the best ocean color model at each site was not significant. Between 1989 and 2007, in situ NPP at BATS and HOT increased by an average of nearly 2% per year and was positively correlated to the North Pacific Gyre Oscillation index. The majority of ocean color models produced in situ NPP trends that were closer to the observed trends when chlorophyll-a was derived from high-performance liquid chromatography (HPLC), rather than fluorometric or SeaWiFS data. However, this was a function of time such that average trend magnitude was more accurately estimated over longer time periods. Among BOGCMs, only two individual models successfully produced an increasing NPP trend (one model at each site). We caution against the use of models to assess multiannual changes in NPP over short time periods. Ocean color model estimates of NPP trends could improve if more high quality HPLC chlorophyll-a time series were available. © 2010 by the American Geophysical Union.
