Abstract

This dataset contains the average weekly shipping density for the whole of the UK at a 2km grid resolution. For 2014, AIS datasets were sampled from the first seven days of each month, commencing with January,at monthly intervals.The total value for all 12 weeks were divided by 12 to determine the weekly average for each vessel group, therefore decimal values may occur for certain cells. The weekly average of all vessel groups were multiplied by 52 to provide the estimated annual average. Please note that the grid used to calculate this dataset is not consistent with that of 2011, 2012 and 2015 data. The data will be recalculated to provide consistent data as soon as possible. The field headings in the attribute table are as follows: 0 - Unknown Vessels 1 - Non-Port service craft 2 - Port service craft 3 - Vessels engaged in dredging or underwater operations 4 - High Speed Craft 5 - Military or Law enforcement 6 - Passenger 7 - Cargo 8 - Tankers 9 - Fishing vessels 10 - Recreational vessels Weekly_Ave - Weekly average of all vessels Annual_Ave - Estimated annual density for all vessels

Quality and validity

Lineage

The MCA supplied type A and type B AIS data on behalf of the MMO. AIS-A is carried by international voyaging ships with gross tonnage (GT) of 300 or more tonnes, and all passenger ships regardless of size. The data contained message types 1, 2, 3 and 5. AIS-B is carried by smaller vessels and is aimed at the leisure and fishing sector. This data contained message types 18, 19 and 24. The validation data was the vessel type details supplied by Lloyds List Intelligence. For full methodology including processing techniques and data outputs please see the MMO1066 reports Mapping UK Shipping Density and Routes from AIS and Mapping UK Shipping Density and Routes technical annex.
