The "Diagnostic Report" project aims to identify the achievements and gaps in the existing BSIMAP and BSIS, to assess the suitability of data for calculation of BSC and EEA indicators, and the relevance of the monitoring system in the BS region to meet the requirements of regional commitments, stipulated in BS legal/policy documents and of the MSFD. Hence, the gap analyses allows identifying areas where further efforts are needed to improve the monitoring and reporting systems in the Black Sea region so that the assessments of pressures, state and impacts could serve in decision-making in the region and fit into Pan-European assessments based on EEA agreed set of indicators, taking into consideration ("forward looking") also the wider approach envisaged in the Annexes I and III of the MSFD.
The examination of BSIMAP, overview of data compiled in the BSIS and outside, and possibilities for indicator-based reporting analyses were undertaken by the BSC PS in a consultation with BS experts. Many scientific institutions in the region contributed to the checks of availability of data outside of the official reporting flow, submitting often full inventories of cruises and meta data on parameters of interest. Generalized requirements (benchmarks for the analyses) to the data and monitoring system have been formulated on the base of EEA methodologies for indicators calculation and on specific needs to meet the obligations of the MSFD in EU-member states.
In total, information about 20 major data-holders, 30 important projects which carried out cruises and/or produced data outside of BSIS and 30 observation systems operating in the Black Sea area has been compiled. Meta data (outside of BSIS) were reported by 15 Institutes, some of them provided full inventories for nutrients, Chl, macroalgae and contamination of biota. The information provided by BS Institutes was further supplemented with the help of extensive Internet search (publications, on-line data sets, GIS, etc.). All collected data/information (BSIS, BSIMAP and outside of them reported by Institutions) were analysed and cross-tables were produced showing availability of datasets in question and their suitability to calculate indicators. A summary of suitability of Black Sea data (of BSIS and external data sources) for calculation of BSC and EEA indicators and MSFD descriptors was prepared in a special table and conclusions were drawn (see below).

On the basis of the numbers of BS indicator that exist in relation to the EEA and MSFD "needs" the following concusions were drawn. Among the eutrophication indicators (inorganic nutrients, chlorophyll and N/P ratio), N/P is not specifically reported to the BSC but as a generic indicator it can be easily derived from BSIS. Chlorophyll is poorly reported to the BSC and the data cannot be used for a regional assessment. However, outside of BSIS Chlorophyll data are available and suitable to build trends and maps of spatial distributon. Nutrients data in BSIS is suitable to trace trends and spatial distribution in coastal waters, but not in the open-sea.
Expansion of hypoxia zones (BSC and MSFD indicator) can not be traced based on BSIS data, however, data are available in the region.
Harmful algal blooms (MSFD indicator) are regularly studied in the Black Sea, the BSIS data are not enough to support this indicator, however, external data are sufficient for regional assessments. Primary production (MSFD indicator) is not regularly studied in the Black Sea to build statistically significant trends or spatial distributions. There are no data in BSIS, and outside of BSIMAP different methods are used to measure primary production, therefore the data are not suitable for comparisons. IBSS-Sevastopol developed equations to calculate primary production from Chlorophyll, specifically for the Black Sea. The method should be verified by other Institutes.
Hazardous substances in biota, sediments (BSC, EEA, MSFD indicators) and their effects (MSFD indicator) are studied in the Black Sea sporadically, the data are not sufficient for regional assessments yet.
Discharge of oil from refineries and offshore installations (EEA indicator) is not reported to the BSC, there is no information on the availability of data in the region. Illegal discharges of oil from ships (BSC, EEA indicator) are considered, EMSA provides satellite images in case of suspected oil spill, however, verification of spills (aerial surveillance, for instance) is still poorly provided by states.
Loads (BSC, MSFD) are well reported to the BSC, data are sufficient for hot spots and rivers. Marine Litter (MSFD) is not a component of the BSIMAP, data outside of BSIS are available, however, assessments are possible for ML on the coast, but not in the Sea and on its bottom.
Most of the BSC Biodiversity indicators are also EEA and MSFD indicators, however, the data supporting those indicators for macroalgal communities in the BSIS are limited, for seagrassess not reported, outside of BSIS available and suitable for building indicators. MPAs are well reported to the BSC, together with threatened and protected species.
Those BSC Fishery indicators which appear also as EEA and MSFD indicators are well reported to the BSC, however, stock assessments for most of the fish species are in need for harmonization.
The EEA indicator "North-ward movement of species" is not reported to the BSC, however, scientific studies in the region are available. Invasive species diversity and abundance (BSC, MSFD) are poorly reported to the BSC. Data outside of BSIS are suitable for the indicators calculation.
Bathing waters data are regularly collected in all Black Sea states, data outside of BSIS are sufficient for tracing compliance with established standards (not yet harmonized in the region).
The report describes the structure of BSIMAP, which was conceptually developed in 2001 and the modifications introduced through the years. National monitoring activities in the Black Sea states are supported by Ministries of Environment. Other Ministries, such as Ministry of Education, Agriculture, Transport and Academies of Science support problem-oriented monitoring in the frames of different projects. Ministries of Agriculture are responsible for fisheries investigations (stock assessments, catches, fishing fleets, etc.) and Ministries of Transport support/supervise most of the investigations related to environment safety aspects of shipping.
The status of national monitoring systems was thoroughly analysed and existing problems were identified against the requirements of the BSIMAP and MSFD. The analysis of identified datasets and BS monitoring/observation systems revealed gaps in regularity and data coverage, gaps in the national monitoring systems in terms of organization/strategy and compliance with commitments, problems with data accessibility, compatibility and suitability to produce indicators.
The major gaps were listed as follow:
What are the reasons for those gaps in BSIMAP? The main reasons can be listed, as follow:
Recommendations to filling the identified gaps in monitoring and reporting have been elaborated, including proposals on development of new indicators, how to improve the existing EEA indicator specifications to make them more suitable for Black Sea assessments, on harmonization of GES identification and wider assessments in EU and non-EU member states, and others.
Therefore, major targets in further development of the Black Sea monitoring to fit into Pan-EU assessments should forsee improvements in:
The supporting activities recommended should focus on:
Crucial issues in the improvement of BSIMAP and BSIS in the Black Sea region are the better coordination between authorities involved, less complicated organization and a strategy for integrated monitoring developed at the national level, using best available examples (e.g. the system in Romania) and assuring sustainable financial assistance for better planning of activities.
