Marine Vessel Traffic Animations

The animated .gif images on this page created from an archive of over 70 million vessel locations show seasonal patterns of marine vessel activity in the Aleutian and Bering Sea Islands region. Four types of vessels are displayed: Bulk Carriers, Dry Goods, Tankers, and Fishing vessels. Reduced traffic in the northern Bering Sea during winter months is primarily due to the presence of seasonal sea ice. Seasonal changes in the routes of bulk carriers and dry goods vessel may reflect storm avoidance using of the lees of the Aleutian Islands where reduced fetch results in calmer seas (Joseph Sienkiewicz - NOAA, personal communication).

Animations created from satellite AIS (Automatic Identification System) data ranging from July 2010 - August 2013. Images include copyrighted material of exactEarth Ltd. All Rights Reserved.

This project is conducted in partnership with the Wildlife Conservation Society and the Scenarios Network for Alaska and Arctic Planning at the University of Alaska Fairbanks.
