This report discusses the capabilities, limitations, and synergies of radar and Automatic Identification System (AIS) information in Vessel Traffic Service (VTS) operations based on published literature and on relevant documentation from the International Maritime Organization (IMO) and the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA).
Prince William Sound (PWS) on the southern coast of Alaska is characterized by high volumes of marine traffic both commercial (oil tankers, fishing vessels) and recreational. The ability to detect potential pollution events is vital for the area?s environmental and economic integrity. The Regional Citizens? Advisory Council (RCAC) was formed to promote environmentally safe pipeline and tanker operations throughout PWS and its adjacent waters. In an effort to support RCAC?s mandate, this project was carried out to demonstrate the utility of satellite surveillance for environmental monitoring in PWS. Using freely available radar imagery from the recently launched Sentinel-1 mission, emphasis was placed on detecting potential oil slicks as well as large vessels transitioning PWS on their way to and from the Port of Valdez.
In 2002, under contract from the Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC), C-CORE assisted in the installation of an ice detection radar on Reef Island in PWS.
