    Edited based on instructions from Ray Sliter, 2/9/2011:
    Two lines from this cruise crossed over the 180 degree line and somehow the nav was lost.
    The only option we had was to digitize the extensions of these lines over 180.
    Please update your "best file" in the "seis" directory for this cruise.
    the new files that need to be added to the master navigation are here:
    /we/ray/nav/line001B_digi.nav (new digitized portion)
    /we/ray/nav/line023B_digi.nav (new digitized portion)

    /we/ray/nav/w1174bs_77-001B.nav
    these fixes were digitized from MAP_28-1.tif
