This dataset describes fishing intensity for Otter mobile bottom contacting gear in 2014 based on VMS/Log book data processed by ICES Working Group on Spatial Fisheries Data (WGSFD). ICES secretariat collected during 2017 relevant VMS and logbook data for 2009-2016 to produce, as a technical service to HELCOM, updated spatial data layers on fishing intensity/pressure. Improved data quality control checks were implemented. Submitted data across the HELCOM area have improved in quality compared to previous data 2009-2013 published in 2015. Standardized methods were used to produce the requested data layers. The code used to create the data products is available here: https://github.com/ices-eg/wg_WGSFD For further technical information on the advice request, see http://www.ices.dk/sites/pub/Publication%20Reports/Advice/2017/Special_requests/helcom.2017.18.pdf HELCOM secretariat did the following processing to the shapefile provided by ICES: - Conversion to ETRS89LAEA coordinate system - Added feature and attribute "Reported" to display unreported areas. Dataset attribute information: c-square: Unique reference of the c-square polygon Year: Year of fishing activity mid_lat: latitude coordinate of the centroid of c-square inWGS84 decimal degrees mid_lon: longitude coordinate of the centroid of c-square inWGS84 decimal degrees SurfaceSAR: Surface area ratio (Swept area, < 2 cm penetration depth of the gear components) Subsurface: Subsurface area ratio (Swept area, subsurface =>2 cm penetration depth of the gear components) totweight: Total Weight (kg) totvalue: Total value (Euros) Kw Fishing Hours: (Kw*h) Fishing hours: (h) Reported: Yes=Reported data. No= No reported data (area that does not contain effort/intensity value due to lack of reported data). Please note that this dataset was updated (v2) in January 2019, see further details below in the lineage section.

Observations of Macroplea pubipennis were collected from the Baltic Sea area for HELCOM Red List species list. The HELCOM Red List of Baltic Sea species in danger of becoming extinct (2013) is the first threat assessment for Baltic Sea species that covers all marine mammals, fish, birds, macrophytes (aquatic plants), and benthic invertebrates, and follows the Red List criteria of the International Union for Conservation of Nature (IUCN). Almost 2800 species were considered in the Red List assessment and about 1750 were evaluated according to the IUCN Red List criteria. Macroplea pubipennis has been placed to the Red List category of Data Deficient (DD) species. Dataset for download contains spatial grid of the Baltic Sea. Distribution of the species can be found in corresponding name column. Values are coded: 1 - Present before year 2000 or in 2000, 2 - Present after year 2000, 3 - Present both before and after year 2000.

Nutrient monitoring activities in the Leningrad and Kaliningrad regions have been implemented within BASE Project. BASE supports the implementation of the Baltic Sea Action Plan (BSAP) in Russia. The monitoring pilot project is focused on the assessment of the nutrient loads coming to the Baltic Sea from Russian part of the catchment. The main activities within the pilot project include nutrient sampling and flow measurements in the river Neva catchment (downstream outlet from Lake Ladoga) and in the water objects of Kaliningrad region (Pregolya and its tributaries, other rivers of Vistula and Curonian Lagoon etc.). More information about results can be found from the BASE Project final report from the HELCOM website.

In 2010, HELCOM completed the initial assessment (HOLAS I) of the ecosystem health of the Baltic Sea – including the associated costs and benefits to the society. The assessment was based on data from 2003 to 2007. The summary report can be found at: https://helcom.fi/wp-content/uploads/2019/08/BSEP122.pdf and more information about HOLAS I at: https://helcom.fi/baltic-sea-trends/holistic-assessments/2010-initial-holistic-assessment/ All datasets for HOLAS I and associated metadata were here compiled.
