  • This dataset is the first dedicated SMOS Sea Surface Salinity (SSS) product for the Baltic basin to enhance the science capabilities in the Baltic region and help to fill the gaps and grand challenges identified by the scientific community. These new product has been created under the funded ESA project ITT Baltic+ Salinity dynamics (4000126102/18/I-BG). This basin is one of the most challenging regions for the satellite SSS retrieval. The available EO-based SSS products are quite limited in terms of spatio-temporal coverage and quality. This is mainly due to technical limitations that strongly affect the brightness temperatures (TB), such as the high contamination by interferences and the contamination close to land and ice edges. Moreover, the sensitivity of TB to SSS changes is very low and dielectric models present limitations in this low salinity regime. Baltic+ L4 SSS product comprises 9 years (2011-2019) of daily maps at 0.05 degrees. A detailed explanation of the product algorithms and validation can be found at http://bec.icm.csic.es/doc/BEC_PD_SSS_Baltic_L3_L4.pdf and in the publication: Gonzalez-Gambau et al., “First SMOS Sea Surface Salinity dedicated products over the Baltic Sea“, Earth System Science Data, 2021 We present here the seasonal averaged Baltic+ L4 SSS products for the period 2011-2019. The daily Baltic+ L4 SSS products can be downloaded from the BEC FTP service (sftp://becftp.icm.csic.es) in the directory OCEAN/SSS/SMOS/Baltic/v1.0/L4/daily/

  • The objective of the BALTHAZAR project has been to assess the potential sources of hazardous substances from landfills/dumping sites, to characterise their environmental risks and to develop measures to reduce the risks of run-off of hazardous substances from waste site to the Baltic Sea.

  • This indicator evaluates the eutrophication status of the Baltic Sea area based on dissolved inorganic phosphorus (DIP) concentration. The measured average DIP is based on in-situ PO4 measurements from oceanographic monitoring data for winter period (December-February) 2011-2015 (umol/l), surface water (0-10 m). More detailed description on methodology can be found at HELCOM Core indicator report (http://www.helcom.fi/baltic-sea-trends/indicators/dissolved-inorganic-phosphorus) and HELCOM Eutrophication assessment manual (http://www.helcom.fi/Documents/Eutrophication%20assessment%20manual.pdf) This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 open sea sub-basins and division of coastal areas to WFD water types or water bodies). The open sea areas have been assessed based on HELCOM Monitoring data and results for coastal areas are based on national WFD results.

  • This indicator evaluates the eutrophication status of the Baltic Sea area based on water clarity measured by secchi depth during summer. The measured average secchi depth (in meters) is based n in-situ measurements from oceanographic monitoring data for 2011-2015 summer months (June-September).
