The Atlantic Ocean is sub divided into areas from the north down to
south and these different areas are used by various stations on both
sides of the Atlantic .The two main areas are in the north covering
Iceland down to about level with Bay of Biscay across to New York is
area NAT-B/C and from that area down to northern Brazil to Dakar is area
NAT-A.
There is a small sub division of NAT B/CÂ between UK / Ireland and
Gander named NAT-F   and south of that a a mall subdivision of Nat AÂ
 named NAT_E.
There are radio stations at New York, Gander, Reyjkavik Shanwick, Santa
Maria and the Canaries.
Planes approaching the ocean will be transferred to the relevant radio
station by ATC so out of JFK this could be New York or up th coast to
Gander. Out of the UK it is Shannwick. Once the Oceanic station is
contacted the planes confirm the flight plan and are given the calling
and secondary frequency of the station covering the point they leave
that area.  Planes travelling north south will be given the station
controlling the area they are transferring to such as Santa Maria in the
Azores.
The oceanic stations may all have web sites and this is the link to
Shannon (Shanwick)
