Description

Areas designated for depositing dredged materials.

MSP Challenge

Dumping dredged materials at sea contributes to the bottom disturbance pressure. The bottom disturbance can influence certain species present in the sea region.

Return to shipping.

In the North Sea region there is data regarding dumping areas that are no longer in use (closed dumping areas), and others that are still being used (open dumping areas).

Original Title

The EMODnet data layer used was the "Dredge Spoil Dumping", the polygon-based layer was used.

Description

The dataset on offshore dredge dumping sites in the European seas was created in 2015 by CETMAR for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several sources. It is updated every year and is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). The dataset contains points and/or (where available) polygons representing offshore dredge dumping sites in the following countries: Belgium, Bulgaria, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Latvia, Lithuania, Malta, Norway, Poland, Portugal, Russia, Spain, Sweden and United Kingdom. Each point and polygon has the following attributes (where available): INDEX_ID, Site name, Country, Dredge ID, Dredged material, Year of operation, Information provider, Distance to coast (m) and Distance from centroid to coast (m)(This last attribute only appears for polygon data).

Original Title

Deposit of dredged material sites points 2011-2016.

Description

"This data set on deposition sites of dredged material (points) reported by HELCOM Contracting parties according to HELCOM recommendation 36-2 for the reporting period 2011-2016.

The dataset contains data reported by nationally by nominated experts by HELCOM PRESSURE group for Denmark, Germany, Estonia, Finland, Latvia, Lithuania, Poland, Russia and Sweden."

Description

For reference, we replicate here the abstract description from EMODnet regarding the Dredge Spoil Dumping (polygons) layer (EMODnet Human Activities data portal , accessed on 25-04-2022):

"The database on offshore Dredge dumping sites in the EU was created in 2015 by CETMAR for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several sources. It is updated every year and is available for viewing and download on EMODnet Human Activities web portal (www.emodnet-humanactivities.eu). The database contains points and/or (where available) polygons representing offshore Dredge dumping sites in the following countries: Belgium, Bulgaria, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Latvia, Lithuania, Malta, Norway, Poland, Portugal, Russia, Spain, Sweden and United Kingdom. Each point and/or polygon has the following attributes (where available): INDEX_ID, Site name, Country, Dredge ID, Dredged material, Year of operation, Information provider, Distance to coast (m) and Distance from centroid to coast (m)(This last attribute only appears for polygon data). The distance to coast (EEA coastline shapefile) has been calculated using the UTM WGS84 Zone projected coordinate system where data fall in."

Creation Date

2015-04-05

Methodology

Clipped data layer to the Adriatic Sea region, reprojected to Lambert Azimuthal Equal Area (EPSG:3035).

Not applicable.

This layer is not present in the Eastern Mediterranean Sea.
