This presentation gives an overview of the results of the EMODnet Sea-basin Checkpoints (Arctic, Atlantic, Baltic, Black Sea, MedSea & North Sea) related to chemistry. The presentation was given by Atanas Palazov, EMODnet Black Sea Checkpoint and Head of the Bulgarian National Oceanographic Data Centre and former Director of IO-BAS, at the EMODnet Sea-Basin Checkpoints Stakeholder Conference held on the 14-15 February 2017 in Brussels.

  2. 2. EMODnet Sea-basin Checkpoints Results Chemistry 2 Mediterranean Data availability for rivers input is high (except for the Pollution events) but spatial resolution and temporal coverage is low Horizontal resolution and coverage for all the characteristic categories are not adequate to develop products Almost all of data are not adequate from the point of view of temporal coverage and validity
  3. 3. EMODnet Sea-basin Checkpoints Results Chemistry 3 Atlantic Data for Nitrate and Phosphate concentration in rivers is scattered, often available from local sources only, with the metadata sometimes incomplete (e.g. measuring date) In the North Atlantic, in EMODnet Chemistry 44% of all raw datasets (i.e. 178 000 occurrences) are available by negotiation, which may lower data access Problems with robustness of EMODnet chemistry data access services were reported
  4. 4. EMODnet Sea-basin Checkpoints Results Chemistry 4 Baltic The observed concentration is often too sparse to calculate loads, while the E-HYPE model can be used to fill in the gaps with good results High data confidence for eutrophication is only found in less than half of all sub-seabasins Both EMODnet and ICES have data that others do not have, but it is more time consuming to download EMODnet data Generally, the sub-basins in transition waters and icing waters were lacking sufficient amount of data for the high confidence assessments
  5. 5. EMODnet Sea-basin Checkpoints Results Chemistry 5 North Sea River inputs data is very patchy The Marine Environment challenge was not able to collect ‘whole-basin’ data for an assessment of Eutrophication. There was a considerable amount of data on water chemistry available through EMODnet on nitrates, phosphates, silicates and ammonium. The primary issue with these data is the way in which dates are formatted. These are not in an immediately usable form and the link to the metadata online returns a blank page.
  6. 6. EMODnet Sea-basin Checkpoints Results Chemistry 6 Nutrient data are rather scarce in the Arctic Rivers Only nutrients and a couple of chemicals are described in the six largest rivers, and the data are recent It is difficult to create time series from the available data Arctic
  7. 7. EMODnet Sea-basin Checkpoints Results Chemistry 7 Black Sea There are significant amounts of chemical data available for Black Sea The available data is sufficient to generate the requested products High number of errors in data format (ODV) More than 60% of data is unrestricted 2016
