The View from St. John’s just a collection of small floes that are easier to navigate through.” The sec- ond phase of the R&D project focused on detecting bergy bits and growlers (less than 1 meter above the surface). During his annual trip from

Newfoundland to the west coast of

Greenland in 2008, Captain

Broderick was able to detect the smaller icebergs in low visibility. At distances up to two miles, he esti- mates a 20 to 25 percent improve- ment with the Sigma S6 system com- pared to standard radar—both in terms of detection and its ability to hold the target over time. The Sigma

S6 system has been installed on more than a 100 ships and offshore plat- forms operating in the Russian,

Canadian, and Norwegian Arctic and sub-Arctic regions, Baltic Sea, Alaska,

Antarctica, and offshore

Newfoundland and Labrador.

The Norwegian Coastal

Administration has been using the

Sigma S6 system for ice operations since 2007, and in 2008 they discov- ered that it can also be used to detect a small oil slick. The Norwegian

Clean Seas Association (NOFO) pro- ceeded to test Rutter’s Oil Spill

Detection system over a three-year period. In August 2010 NOFO certi- fied that the system meets these stan- dards for NOFO oil recovery vessels: “(1) The vessel must have an oil detec- tion system permanently installed that gives automatic detection, and (2) Must be able to present area and position determination of oil slick, operating history, speed and direction of the slick.” NOFO is currently operating two of these systems on oil recovery vessels. The system is also deployed on other oil spill recovery vessels in Norwegian waters as well as a Statoil platform. “To date,” said
