Low virus to prokaryote ratios in the cold: benthic viruses and prokaryotes in a subpolar marine ecosystem (Hornsund, Svalbard)

The density and spatial distribution of benthic viruses and prokaryotes in relation to biotic and abioticfactors were investigated in sediment cores collected in Hornsund, a permanently cold fjord on the West coast of Svalbard,Norway. The cores were obtained from the mouth of the fjord to the central basin, along a longitudinal transect. Theresults of our analyses showed lower densities of viruses (0.2 × 108 to 5.4 × 108 virus-like particles/g) and lower virus-toprokaryoteratios (0.2-0.6, with the exception of the uppermost layer in the central basin, where the ratio was about 1.2)at the study site than generally found in the temperate areas, despite the relatively high organic matter content in subpolarsediments. Variations in benthic viral and prokaryote abundances along gradients of particle sedimentation rates, phytopigmentconcentrations, and macrobenthic species composition together suggested the influence of particle sedimentationand macrobenthic bioturbation on the abundance and spatial distribution of prokaryotes and viruses in cold habitats.

Possibilities of integration of monitoring requirements by other EU and national legislation

Deliverable 1.3 provides inventory of legal regulations, initiatives, developed projects and technologies having potential influence on sensors design processes. Report focus on possible integration of monitoring requirements by other EU and national legislation. Structure of the report consist of: 1. Inventory of EU directives bringing legal regulations providing requirements for having potential influence on sensors design and measurement methodology in reference to parameters demanded, spatial and temporal resolution of data and availability of information for potential users, 2. Inventory of conventions adopted by European Countries, approaching to reach and keep Good Environmental Status, having impact on monitoring processes and fostering development of technical infrastructure, 3. Analysis of national legislation implementing EU directives and representing approach to develop appropriate infrastructure for monitoring duties 4. Inventory of projects developing technologies having potential influence on sensors design, measurement and monitoring methodologies. 5. Inventory of innovative technologies, initiatives and ongoing policy developing processes as source of requirements for perspective technology development These identified items are drivers of new technologies development processes. Sensors, as a part of bigger systems and infrastructures interoperating each other have to conform regulations formulated in legal acts in the context of parameters measured, condition of operation, interaction with environment as object of examination, transmission protocols and data collections terminating data acquisition, processing, storage and information extraction and exchange processes. Objectives The objective of the report is to provide inventory of regulations, directive and conventions having potential influence on sensors design, measurement and monitoring methodologies development having potential influence on sensors design processes. Rationale New developments in the field of technology, measurement and monitoring methodologies, policy and law regulations, possibilities and demands for integration of monitoring requirements by other EU and national legislation, and interoperability challenges are factors determining perspectives of sensors development. Report on regulations, directive and conventions having potential influence on sensors design will include the analysis of possibilities of integration sensor's functionality to meet monitoring requirements and to help to distinguish sensitive or vulnerable areas where monitoring is necessary according to identified ecosystem properties

Marine ecosystem services: Linking indicators to their classification

© 2014 Elsevier Ltd. All rights reserved. There is a multitude of ecosystem service classifications available within the literature, each with its own advantages and drawbacks. Elements of them have been used to tailor a generic ecosystem service classification for the marine environment and then for a case study site within the North Sea: the Dogger Bank. Indicators for each of the ecosystem services, deemed relevant to the case study site, were identified. Each indicator was then assessed against a set of agreed criteria to ensure its relevance and applicability to environmental management. This paper identifies the need to distinguish between indicators of ecosystem services that are entirely ecological in nature (and largely reveal the potential of an ecosystem to provide ecosystem services), indicators for the ecological processes contributing to the delivery of these services, and indicators of benefits that reveal the realized human use or enjoyment of an ecosystem service. It highlights some of the difficulties faced in selecting meaningful indicators, such as problems of specificity, spatial disconnect and the considerable uncertainty about marine species, habitats and the processes, functions and services they contribute to

Deliverable 3.6 zoning plan of case studies : evaluation of spatial management options for the case studies

Within MESMA, nine case studies (CS) represent discrete marine European spatial entities, at different spatial scales, where a spatial marine management framework is in place, under development or considered. These CS (described in more details below) are chosen in such a way (MESMA D. 3.1 ) that they encompass the complexity of accommodating the various user functions of the marine landscape in various regions of the European marine waters. While human activities at sea are competing for space, there is also growing awareness of the possible negative effects of these human activities on the marine ecosystem. As such, system specific management options are required, satisfying current and future sectoral needs, while safeguarding the marine ecosystem from further detoriation. This integrated management approach is embedded in the concept of ecosystem based management (EBM). The goal of marine EBM is to maintain marine ecosystems in a healthy, productive and resilient condition, making it possible that they sustain human use and provide the goods and services required by society (McLeod et al. 2005). Therefore EBM is an environmental mangagement approach that recognises the interactions within a marine ecosystem, including humans. Hence, EBM does not consider single issues, species or ecosystems good and services in isolation. Operationalisation of EBM can be done through place-based or spatial management approaches (Lackey 1998), such as marine spatial planning (MSP). MSP is a public process of analysing and allocating the spatial and temporal distribution of human activities aiming at achieving ecological, economic and social objectives. These objectives are usually formulated through political processes (Douvere et al. 2007, Douvere 2008). Within MESMA, a spatially managed area (SMA) is then defined as “a geographical area within which marine spatial planning initiatives exist in the real world”. Marine spatial planning initiatives refer to existing management measures actually in place within a defined area, or in any stage of a process of putting management in place, e.g. plans or recommendations for a particular area. Management can include management for marine protection (e.g. in MPAs), or management for sectoral objectives (e.g. building a wind farm to meet renewable energy objectives). Within MESMA, SMAs can have different spatial scales. A SMA can be a small, specific area that is managed/planned to be managed for one specific purpose, but it can also be a larger area within which lots of plans or ‘usage zones’ exist. This definition is different from the definition mentioned in the DoW (page 60). The original definition was adapted during a CS leader workshop (2-4 May 2012 in Gent, Belgium) and formally accepted by the MESMA ExB during the ExB meeting in Cork (29-30 May 2012). MSP should result in a marine spatial management plan that will produce the desired future trough explicit decisions about the location and timing of human activities. Ehler & Douvere (2009) consider this spatial management as a beginning toward the the implementation of desired goals and objectives. They describe the spatial management plan as a comprehensive, strategic document that provides the framework and direction for marine spatial management decisions. The plan should identify when, where and how goals and objectives will be met. Zoning (the development of zoning plans) is often an important management measure to implement spatial management plans. The purpose of a zoning plan (Ehler & Douvere 2009) is: To provide protection for biologically and ecologically important habitats, ecosystems, and ecological processes. To seperate conflicting human activities, or to combine compatible activities. To protect the natural values of the marine management area (in MESMA terminology: the SMA) while allowing reasonable human uses of the area. To allocate areas for reasonable human uses while minimising the effects of these human uses on each other, and nature. To preserve some areas of the SMA in their natural state undisturbed by humans except for scientific and educational purposes.peer-reviewe
