Disposal sites areas 36/2

This dataset contains disposal sites reported by HELCOM Contracting Parties, according to the HELCOM Recommendation 36/2 ( https://helcom.fi/action-areas/industrial-municipal-releases/dredging/). The disposal sites are grouped by spatial data type to pointwise, line and polygon datasets. Data covers the years 2006-2022.


The data format is defined in the HELCOM Guidelines for management of dredged material at sea ( https://helcom.fi/action-areas/industrial-municipal-releases/dredging/).


Attribute information (heading for downloadable shapefile):


Helcom site ID (Helcom_sit): Unique id for deposit site

Dredging ID (Dredging_I): Dredging site id, where material originates from

Unique ID (Unique_ID): Unique id for each depositing activity (Helcom site ID + Dredging ID + year)

Site name (Site_name): Name of the deposit site

Type of area dredged (Type_of_ar): Type of area that was dredged (e.g. harbour or sea)

Dredging activity (Dredging_a): Maintenance or capital dredging

Material deposited (Material_d): The type of material deposited (e.g. sand, silt)

Amount deposited (tonnes) (Amount_dep): Amount of material that has been deposited to deposit site, tonnes dry weight

Amount beneficial use (tonnes) (Amount_ben): Amount material used for beneficial purposes, tonnes dry weight

Beneficial use (Beneficial): Description of beneficial use

Year (Year): Year of activity

Country (Country): Contracting Party of HELCOM

Sub-basin (Sub_basin): HELCOM sub-basin (assessment unit level 2) where activity has taken place

Comments (Comments): General comments related to activity

Contaminants Cd - SPAH9: Amount of contaminant deposited, in tonnes dry weight

Contaminants SPCB7 - MBT : Amount of contaminant deposited, in kilograms dry weight

Other contaminants (kg) (Other_cont): Any other contaminant deposited (substance indicated in "notes")

Petroleum HC (tonnes) (Petroleum_): Amount of Petroleum HC deposited, in tonnes dry weight

HCB - DEHP DBP BBP: Amount of contaminant deposited, in kilograms dry weight

Contaminant notes (Contaminan): Notes related to contaminant load

Permit (Permit): Deposit site permit reference

Quality flag (Quality_fl): Quality flag of data

- Quality assured: Data is quality assured either in the annual verification or in a separate quality assurance process by EN DREDS

- No quality assurance: Data is not quality assured due to the reason that process has not been carried out

- No Quality assurance possible: Data quality assurance process has been made, but it was not possible to find the reference data to verify the parameters

Statement

The disposal sites are grouped by spatial data type to point, line and polygon datasets. The data format is defined in the HELCOM Guidelines for management of dredged material at sea. https://helcom.fi/action-areas/industrial-municipal-releases/dredging/


Data quality aspects


Two separate quality assurance processes of old reported data 2006-2016 have been carried out during 2018. In addition annually reported data is verified by Contracting Party before making the data publicly available. Attribute "quality flag" in the data provides information on the quality status of individual depositing/dredging activity.


Denmark


Denmark can only quality assure data from 2013 onward. Denmark cannot review the raw data for 2009 and 2010. The reason for this, lies in the history of the monitoring of dredged material in Danish waters: Before 2013, the responsible authority was decentralised in Denmark, meaning that the different regions had very different formats for reporting of dredged material. In 2013, all dredging activities were centralised to the then national agency of nature. Thus, Danish data older than 2013 has been removed from HELCOM database.


Sweden


Information on the calculation of contaminants prior to 2013 is scattered, and not possible to trace fully. Data from 2013 onwards is quality assured.
