AIS DATA

 

The file downloads provided below are density plots of vessel transits created using Automatic Identification System (AIS) data from calendar year 2010 plotted on NOAA nautical chart backgrounds.

The larger gridlines seen on the plots are Outer Continental Shelf (OCS) lease blocks and the smaller blocks are referred to as aliquots and are 1/16th of a lease block.  The larger 4-digit numbers in each lease block are the lease block numbers.  The smaller numbers seen in the aliquots are the total vessel counts that passed through the aliquot in a one year period.  A vessel is counted each time it enters and exits an aliquot so it is possible to be counted more than once if the vessel enters and exits multiple times. 

The files are Adobe Acrobat PDF files that can be viewed using Adobe Acrobat Reader available free at www.adobe.com.  The files are provided in high resolution to allow users to zoom in with minimal loss in clarity.  They are also layered PDF files which enable you to select which layers you would like to display.
