30th meridian west

The 30th meridian west forms a great circle with the 150th meridian east, and it is the reference meridian for the time zone UTC-2.

Between the 45th and 61st parallels north, the meridian forms the boundary between the Gander and Shanwick Oceanic air traffic control areas, and for this reason is also known as the "Molson-Guinness Line".^[2]
