Fishing intensity DRB MOL 2011 v2 |
Short description |
This dataset describes fishing intensity for DRB MOL mobile bottom contacting gear in 2011 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

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. |

HELCOM secretariat downloaded the data and did the following processing to the shapefile provided by ICES:
- Conversion to ETRS89LAEA coordinate system
- Added feature and attribute "Reported" to display unreported areas.
After processing, the datasets were publsihed via HELCOM Map and Data service as individual map layers.
