Observations of Nerophis lumbriciformis 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. Nerophis lumbriciformis has been placed to the Red List category of Least Concern (LC) species. The map shows the sub-basins in the HELCOM area where the species is known to occur regularly and to reproduce (HELCOM 2012).

Total (monthly, and 5 year average) discharge from hydropower dams (m3/s). Data includes the water that passes the turbines as well as the water not passing the turbines. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Estonia, Finland and Sweden. The activity was declared as not relevant in Denmark, Germany, Latvia, Lithuania and Poland. Data contains only those hydropower dams that are situated closest to the Baltic coast (less than 40 km), are the first ones from the coast in the river network and have a direct connection to the Baltic Sea trough river. Swedish data is a combination of actual measurements and modelling. Modelled data have been calculated with s-hype2012_version_3_0_0. These data are also presented online at http://vattenwebb.smhi.se/regulations/. Please note that data from 2015 is provisional and may be subject to revisions.

This core indicator evaluates the status of the marine environment based on concentrations of Polyaromatic hydrocarbons (PAH) metabolites in biota. Quantitative threshold value is used to classify core indicators status in “Achieve”, “Fail” or “Not assessed”. As There is no commonly agreed threshold value for measuring metabolites available, this report only considers concentrations of contaminants. This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas and division of the coastal areas by WFD water types or water bodies).
