W
Meridians east of the prime meridian are labeled with the letter E, which stands for east. The prime meridian itself is labeled as 0° longitude, and meridians to the east are assigned increasing positive longitude values.
Longitudes west of the prime meridian are given either as "40 degrees W" or "-40 degrees", with degrees represented by the "o" degree symbol.
The name of the meridian that is labeled 0 is the Prime Meridian.
The Prime Meridian effectively divides the continent of Antarctica in half. Since prime meridians are arbitrary this is based on the Greenwich Prime Meridian.
The Prime Meridian The International Date Line
The Prime Meridian is numbered zero degrees. Meridians, or lines of longitude, are numbered with increasing numbers of degrees both east and west of the Prime Meridian. On the opposite side of the world from the Prime Meridian is 90 degrees, which is also the International Date Line.
Vertical lines parallel to the prime meridian are lines of longitude.
