IMPOSEX_2014_CONT1_NASSARIUS
Description
The information contained in this dataset refers to the Cont-IMP/14 campaign (IMPOSEX 2014). Descriptor 8 of the Marine Strategy Framework Directive states that it is necessary to assess the concentration of pollutants in the marine environment and their effects, taking into account the impacts and threats to the ecosystem. One of the indicators selected to evaluate descriptor 8 is the study of the specific biological effects of tributyltin (Imposex) on marine gastropods. The main objective of the campaign was the sampling, under standardized conditions, of marine gastropods (Nassarius reticulatus).
The area covered by the data provided is part of the North Atlantic Marine Demarcation of the Member States, specifically on the Galician coast.
It is a data set composed of point elements, where each element represents the sampling point of marine gastropods: Nassarius reticulatus.
Each object is associated with a series of alphanumeric variables such as the name of the sampling point, the name of the campaign, the date and georeferencing, according to the GIS protocol of the Spanish Marine Strategies project (ESMARES).
The sampling of Imposex in the Galician and Cantabrian coasts has been carried out by the group of J.M. Ruiz (Coastal Biology Research Group) of the Universidade da Coruña from 1996 to 2017. Since 2014, the IEO has been carrying out sampling and analysis in collaboration with the Universidade da Coruña.
The geographical information collected is stored in a spatial database.
This work has been financed thanks to the project ‘Technical Scientific Advice for the Protection of the Marine Environment: Evaluation and Monitoring of Marine Strategies, Monitoring of Protected Marine Areas of State Competence (2018-2024)’. Marine Strategies are the marine environmental planning instrument created under Directive 2008/56/EC (as amended by Directive 2017/845) establishing a framework for Community action in the field of marine environmental policy (Marine Strategy Framework Directive), and have as their main objective the achievement of the Good Environmental Status (GES) of our seas. The 11 Good Environmental Status descriptors form the basis for the description and determination of good environmental status of the marine environment. They are established by the Directive in its Annex I. The marine assessment areas are located within the Marine Reporting Units (MRUs) defined in the framework of the Marine Strategies of Spain.
